@@UABlackCat just making that back yard power 💪😎

@@justin4588 don’t worry I’ve rebuilt this motor already with new internals and gapped piston rings to run more boost

@@AmirUniqueTuni 100% yes it’s exactly the same if you look at a n52b30 and an n52b25 you wouldn’t be able to tell the difference if it wasent in the car it will just make a bit less power then the n52b30 but the process and what you need is exactly the same down to the last bolt. if you follow my other videos on how to boost and what u need the process is the same and Itill get u boosted 👍

@@AmirUniqueTuni I would recommend pulling a clutch and flywheel from an n52b30 or any awd variant will have a 240mm pressure plate and clutch disk this is a big upgrade for the n52b25 rwd cars just fyi

@@rumrunnersracing Thank you for information, I have zf6hp automatic gearbox, flash tuned with xhp, will it work when I boost engine? Also where did you buy turbo kit for your engine? What is the reliability after the turbo installation because this is my daily car, just wanna know. 😃

Auto will handle the boost fine just keep it 7-10psi and the engine will love it. My turbo “kit” was pieced together mostly from Amazon and from eBay. The turbo is from Amazon it’s a gt35 the exhaust manifold was made in house by a friend of mine and my ecu is a custom standalone made in house by another friend of mine lol. It will be on the market to buy spring 2025 we’re just boosting an automatic car to work out the functions for auto cars and the awd cars so you can electronically switch from awd to rwd whenever you want. But you can keep it cheap and flash tune your stock ecu and just modify your manifold and put a flange on if you weld. The engine is reliable if you do your daily maintenance and don’t go over 10psi or you will need to open the engine and gap piston rings. Any other questions u have during the process u can post here I reply to all of the comments on my videos good luck 👍

@@yyskrta thanks I appreciate the positive feedback 👍 this new setup should hit the dyno sometime after Christmas holidays.

@@evensisftw top end is all stock besides having fully tunable valvetronic settings as well as boost with my one of one standalone made by popformance other then that stock head studs stock valves and springs. The weak point isint wrist pins or even pistons it’s piston rings when they touch Itill blow out the wrist pin because Itill bind in the cylinder the stock gap in these cars is super tight that’s how I went through 2 motors prior all same issue to much boost piston rings touch each other and part of the piston decides to go swimming in the oil pan. If you boost more then 11psi u gotta gap the rings at the very least I went a bit farther and put in low compression pistons as well so I can run 18-20psi own the new setup it’s just waiting for good weather to hit the dyno.

​@@rumrunnersracing Makes a ton of sense mate, nice one for that. Yeah no plans to go beyond 10 pounds lol, will definately want to get that bottom end done looking at this as won't be long till get used to the power :D Looking forward to your dyno results!!!

@ yea buddy I’ll keep u posted I can’t wait to get the new setup dialed in and if you have any questions that u don’t find answers in my other videos feel free to hit me up again in the comments I don’t mind spreading the knowledge good luck on the supercharging 👍

@@titorivas5623 the computer is a standalone that runs the car by itself and keeps valvetronic and boost so it’s a one of a kind until more get made in the spring right now it’s a one of a kind from popformance my buddy is getting into making ecus he made some for a few Nissan skylines and 300zx and now for the n52 it’s completely plug and play to replace the factory ecu it should be on the market spring 2025 so far it’s been amazing just working out the software for the automatic cars and a few other things then it will be ready for public purchase

@@titorivas5623 it uses a custom built standalone designed for the n52 to control valvetronic and boost made by my buddy at popformance we’re working on the features for the automatic cars and updating the software before it gets released to the public should be available sometime in spring 2025 you can inquire about getting a pre order at www.popformance.com

@@anonymoustruthaboutworldsp938 you only really feel it stabilize over 150ish kmh but from 150-220 you would be surprised I took the wing off thinking less drag but it is actually a lot less stable at high speeds so I dunno if u were being sarcastic but rwd cars do benefit from some downforce for stability and to put pressure on the rear wheels for grip to not spin when slamming gears on a no prep drag strip but not when city driving so long story short yes the car goes fast the wing helps stabilize the car 🧐…. 😆

@@betolopez1021 it’s only good for turbo cars if you have a non turbo car they run higher compression to make more power. Turbo cars have air compressed and pumped into the engine so they have more pressure in the cylinders so they run lower compression ratios to gain timing and be able to run more boost safer. High compression + high boost= blown motor. Also the piston rings need to run a bigger gap then n/a cars as well so the rings can expand more due to increased heat and cylinder pressure. Hope that helps if There’s anything u want me to elaborate on just ask I don’t mind passing down knowledge to the bmw fam 😎 👍

@@titorivas5623 my car uses a custom standalone that runs everything it was made by my tuner at popformance it works with the tuner studio software. It’s a prototype I’ve been running for the last year it should be available to buy by next spring we’re just doing some updates on the valveteonic coding. This is the only car that uses full valvetronic control on a standalone it’s pretty sweet like having a tunable camshaft. This car is scheduled to hit the dyno after Christmas.

@@lateatnight8323 I’ve already had an n54 fbo Theyr great but maintenance and parts if anything breaks are expensive af and I’ve got 3 kids so I can’t even afford a set of injectors or the walnut blasting upkeep for the n54 😆 but the n52 is all over my local scrap yards so I work with what I got and play with what I can get my hands on cheap and when things go on these n52 cars ppl just give them away for real cheap Theyr the new e46 I think

@ I’m glad you’ve seen both sides and can honestly speak on both, plenty of people bitch and cry about the n54 being “junk” but haven’t had one

@ yea I don’t hate the n54 at all if parts were cheaper and maintenance on their direct injection you can’t beat the n54 it’s the German 2jz just a single turbo and it’s ready to go and the jb4 tuner is sick af my tuner and I are developing a standalone for the n52 that’s y I’m so overly invested it will be the first n52 to have tunable valvetronic tables as well as using boost its pretty sweet It should really help the n52 guys looking for that n54 power on the n52 budget 😆

I think they are the new e46 also. Would love to grab up a rwd one and keep it and my Xdrive possibly "forever​". But i really want to get a E39, whatever opportunity opens first. @@rumrunnersracing

@ I have a buddy selling a boosted e39 drift car there’s a few videos it’s in on my channel if u wanna check it out

Thanks I appreciate the compliment a lot of time and effort went into this build when the new setup hits the dyno it should set n52 records at least 600whp is what were shooting for I’ve made 600whp before but stock ring gap dosent play well with anything 14psi+ lol this is engine #3 so by now I have worked out a lot of the issues 🤷‍♂️

@@smartiesnestle6679 it’s a gt35 from Amazon it was like 250$ around there and it has been going strong we bought one for my buddys e39 as well Theyr pretty stout

@@josephchewning919 not really if you know how to drive a manual 🤷‍♂️ but I see what your getting at

@ lol if I go through a set of gear from bottom to top I can learn the ratios and rev match all the way back down first time. I also dont slam my gears through the synchronizers, I let the synchros do the work.

And if I break any synchros I’ll let u know first 😜 👍 but so far nothing I know where this car likes the shifts I’ve got no worries for the trans rods is my main concern going forward shooting for 600+whp on a drift setup if u saw my videos u would see this is an old shifter setup and motor setup but either way I know my car like every driver does I just don’t like reaching so far from a short shift to the hydro e brake and back I like when they’d more equal length and the hydro needs the leverage it’s more of a personal preference but to each his own if ur feelin ur setup over mine I don’t mind I’m just glad ur driving manual 😎 👍 keep manuals alive. What do u drive?

I had my buddy just weld one up for me it’s not to hard there’s a few designs you can make a few v band clamps and some pipe bends and you could have one ready to go. I don’t think the ones Theyr selling online are worth the price you can buy the pipe and the welder to make one yourself for the prices I’ve seen online it’s just a bit of time getting the placement right.

@@Alfonso-mh1np yea she flows good I just swapped to lower compression pistons and opened the ring gap I’m going to go for more then 14psi I wanna go for 18-20psi. The cars together and running I just gotta do a slow break in with the engine then it goes to the dyno.

@@rumrunnersracing what pistons did you use? n51?

@ in this video those are stock n52 pistons and all stock internals 145k on the engine. In the new build I just used 9:3:1 compression pistons I got on eBay and opened the stock ring gap but the car dosent hit the dyno for a bit with the new setup the car is scheduled for a full retune in the dyno sometime after Christmas.

@@pistolpaulie4871 I never looked it up it’s more just tight is tight type deal u don’t gotta go to hard as long as u feel the rubber squish down ur good just go over all of them once at the end to make sure u didn’t skip tightening any and ur good to go 👍

@@007-K2 this motor was 152k on it and I blew piston number 6 from boost creeping to 16psi to many times. So if you check the page u can see my rebuild with lower compression pistons and how I gapped the piston rings for higher boost the new goal is 18-20psi with the new low compression pistons but stock you could run 7psi for years and have no issues it’s when you get 12psi and above you see what parts don’t like boost 😆

@ so If I took time out to save up and rebuild the motor with lower compression with 12psi as a goal, would you be able to daily that?

@ 100% just gap the piston rings as well debatably you could run 12psi daily with just gapping the piston rings to handle the boost that’s what the biggest issue to running boost in n/a cars run a tight ring gap turbo cars run a bigger gap so the rings can expand with the added heat and pressure in the cylinder so low compression pistons and gapping rings could be overkill if you don’t plan on abusing the car at the track like I do.

@@mauriziobossoli5200 it depends how much power you want to make I went overkill on fueling and engine management but you could toss a setup together for a few grand if you can make your own exhaust manifold and source some cheaper bigger injectors and aftermarket fuel pump

@@bagelmonster420 this is actually last years setup those shifters have been swapped out with wrenches 🔧 I made into a hydro and shift handle that sword handle was laying around my shop and I lost the actual shift knob. But the wrenches are cool af but not much shorter 😆

Thanks me 2 can’t wait to use it again after the car gets tuned.

Yea buddy it hits hard might be my new catch phrase 😆👍

@@Realitywords89 it’s just a kit I threw together using the basics of what you need to boost it’s pretty universal most parts are from Amazon or eBay and the manifold my buddy made for me at his shop. I have a video on basics of what you need to boost your e90 if u wanna check it out 👍

@@Realitywords89 we may make a kit next season due to high demand just working out a solid manifold design

This actually an old setup I swapped both handles with actual wrenches 🔧 I welded on 😎

Yea it’s a bmw thing they love the check engine lights 😆

Yea I have an oil cooler just unsure how I wanna plumb it up 🤔 any suggestions?

​@@rumrunnersracing you could use the n54 oil filter housing which would make a lot easier and straightforward

@ yea I thought that I’m just broke af so fittings and the housing are things I can’t afford atm still waiting on a sponsor for the channel 😆 that’s y I tap the stock plastic oil cap for my feed 🤷‍♂️ but if I even see an n54 in the scrap yard I’ll be all over it 🤩

Also fun fact about n52 cooling it’s entirely controlled by the standalone I have so the stock radiator is fine because when my standalone sees the car drifting hitting the limiter it just opens the thermostat max and keeps the car in the mid 80’s the tech in these cars is pretty sweet. I did put a massive intercooler in there tho to keep the iat’s cool

You know it buddy did a test drive today and she’s running like a dream just gotta drive a few days before it goes on the dyno 😮

​@@rumrunnersracing yessuh 🔥🔥🔥

@@kontext4277 thanks man I’m all over it this is engine #3 all pulled and installed on this gravel 😆 but this is the first one I opened up and built it to handle more then the 14psi that blew the other 2 motors. It should be going to the dyno soon. 3 years still have t got to the track but that’s comin 2025 gunna be a big year 👍.

@rumrunnersracing 👏🏽👏🏽👏🏽 well I'm looking forward to it bro

Yea the buy an n54 is usually a big one i get 😆 but I’m way to deep into the n52 rabbit hole 🕳️ to start digging my way out now lol. thanks for the support I just hope this inspires other ppl to make power. I actually just got the transmission issue fixed and today I finally take it out for a test drive after the rebuild.

@rumrunnersracing I mean if you worked out the links you could make kits with eBay turbos and sell them to people like me that have limited welding abilities haha. Good stuff tho brother. My plan is JUNKYARD LS

Yea to be honest man if I was where u are had a chassis with no motor ide do 5.3l ls they love boost and can make cheap reliable power. I plan on buying another e90 shell and doing another series going the ls route but same style I always do scrap yard parts and a ton of diy 😆. There’s lots of ppl making kits out there but none ide buy most are incomplete because ppl just want 7psi and call it a day so they don’t have rising stuff like rate fuel pressure regulators they don’t gap piston rings and the one that gets me is they boost there cars and no cool thrashing videos of e90’s sending it. My car gets driven like it’s stolen 😆 I just gotta get more videos to show ppl how sick these cars can be. But next is 5.3ls.

That sucks man i hope u get your frs fixed I was in that boat I ended up buying another e90 with a bad oil pan leak i got dirt cheap just to daily because the r&d on this car actually took years I’ve been at this 3 years now changing the setup adding things overcoming issues for more power gains and I hardly got drive time out of it but was constantly working on it. But that same n/a e90 just took all kinds of abuse and loved it I use to slide the n/a e90 every time I drove it so even without boost these cars are sick af 👍

@rumrunnersracing they're definitely fun af NA. I ended up having the crankhub spin on mine on Tuesday but got it retimed and its better than it has in a while. Definitely a platform that's deserving all the revent r&d

@@IIINGWO with my turbo manifold setup there’s no clearance for anything over 3” to fit behind the manifold I actually had to bend part of the pipe in the vice just to make room. Trust me this thing sounds nasty when you get hard into the boost.

@@IIINGWO I made this with my Amazon welder 👨‍🏭 and straight pipe I bought from my local exhaust shop it’s a literal straight pipe under the car from the the Downpipe to the rear then there’s a single 45 bend to set the tailpipe where it needs to be I’ll put up a video about it my buddys get a kick out of it 😆

@rumrunnersracing Oh ok I hear you G

@@IIINGWO hasent hit the dyno yet I got the engine together and in the car then my throw out bearing started to go so I just pulled the trans last night getting it back together tmrw then break in then dyno. Last setup I made a bit over 600whp on the dyno but we had to back it off due to intake temp issues so it sat around 480whp we’re going to shoot for over 600 on the hub dyno to make it one of the highest hp n52 motors around

@rumrunnersracing Ok brother will be here when the jobs are done.

@@IIINGWO cars done and driving I gotta do the break in for 200km of running break in oil and grandma driving before i can swap to the synthetic and then she goes to the dyno we’re looking at late November getting it on the hub dyno so look out for that video for drop soon 😎

@rumrunnersracing is understandable, and that's a must.

@@jeffthekiller6648 in this video they’re completely stock I didn’t open this engine just added the turbo and fueling mods with a standalone ecu. Since this I’ve swapped to low compression pistons and gapped the piston rings for higher boost. Those videos are on the way soon the car goes to the dyno in the spring to get dialed in.

@@rumrunnersracing be cool to see more experiments done 👀 like n54 rods used and maybe see if the closed deck conversion fits the n52 block as well

@ I was going to upgrade rods but they are forged from factory so if they fail then I’ll swap in the next build the main thing this build has going is it’s the only one to use boost and valvetronic functionality the n54 dosent do that. If I ever get sponsored I will definitely be willing to experiment more with these bmw platforms 👨‍🔬 🧪 closed deck and getting steel sleeves with water methanol injection and aftermarket head studs it would make big power I have a ported head I’m working on as well that’s going to be put in next season after I dyno it and see what gains it gives me.

@@rumrunnersracing you have ig? I'm planning on building a back up n52 for when I get the eurocan turbo kit 😂

No I just have Facebook in the admin of the rum runners racing facebook group it’s just me and a few buddys started out as local roll racing now it’s just me doing next level n52 stuff

@@ethansimon6216 and let’s not forget the sound of that turbo spool there’s nothin like it 🎶 if my slave cylinder didn’t randomly quit on me after I got the new motor setup in it would have been on the dyno already

@ things happen ppl who drive and work on their shit understand

When you see the video where I show the damage Its crazy it started at all and I was able to drive it into my barn I’m surprised it didn’t lock up the cyl6 was missing like 20% of the bottom of the piston. This is engine #2 that this happened to running 14psi so I did an overhaul on engine #3

Yea it’s was piston #6 ring land let go since this video I’ve rebuilt the engine with new low compression pistons and gapped the rings to 0.023 so it’s ready to see 18-20psi but my clutch slave cylinder quit on me so that’s my newest issue 😅

@@Builds23 I’m shiftin like a samari 🥷 😆

@@Elbmwenthusiast there’s no set spec for gapping rings u do it for how much boost you plan on running you only need one tool the piston ring grinding unit my buddy used in the video and we recommend doing 5 rotations then measure then another 5 it’s better to go slow because if you take to much material off there’s no going back. Both top rings get gapped and the oil ring at the bottom gets left alone I shot for 0.023 stock was 0.013 you could just go for that. How much boost do you plan on running with your setup?

@@rumrunnersracing OK I’ll go off base with the recommendation that you gave me cause I’m trying to aim for at least 19 psi if possibility, but you’re already doing all the things ahead of me what I’m doing because I’m already rebuilding my engine as well with the n52 that already has 150 K mileage I’m learning from you because halfway through I’m already buying all the parts to throw a turbo on it

Glad I could help pave the way but I would start lower boost and work your way up I would thrash it at 10-12psi work out the kinks of the build if there is any then work your way up. Also tuning is key when running high boost you will not be able to rely on any remote tunes or anything you get online you will want real time tuning or the motor will just blow the head off. That being said the one thing I didn’t address is how strong stock head studs are will they be able to handle 18-20psi I’m not sure 🤔 but to help the situation I will be adding water methanol injection to keep intake temps down that’s another crucial part of the setup hot intake temps and high boost will also blow the engine. What is your plan for tuning?

@@rumrunnersracing my plan was going to Stage FP for tuning for turbo. I also was looking into 22 RPD which I heard from both parties they are good but as you said, I think remote tuning is not as good for turbo because yeah you might end up blowing a head gasket so what I’m going to do is an ECU exchange or buy an AEM ECU for a piggyback just in case or just ship my car all the way out there lol but I heard stories about they’re tuning capabilities with turbo and superchargers and they are pretty good and as well as 22 RPD, but yeah as you said, let me start off low first start before I go high

@@Elbmwenthusiast nice man sounds sick also you will have to lock your valvetronic at whatever height you want to run because other standalones or piggyback ecus wont have the ability to control valvetronic that’s y my car made such good power my ecu is custom made by my tuner to use full valvetronic function with boost you man be able to snag one of the first ones my tuner is finalizing it over this winter before he makes a run of them. He’s just working on all the automatic functions because testing was all done on my car and i converted this car to manual almost immediately after I got it. My tuners website is www.popformance.com he’s a Tuning wizard and makes ecus and all sorts of stuff you could inquire about tuning and the standalone development thro his website his names Patrick tell him Matt with the e90 gave u the info 👍. Ide love to see progress pics do u have any Instagram or anything?

Got that long throw 😆 but she bangs the gears pretty good I’m not a fan of short throw shifters it’s to much travel from the shifter to the hydro e brake. This way u swap back and forth easily.

@@thecrazyy2O4 I don’t get the question lol any n/a car can be turbocharged Ls motors never came turbo but boosting them is the easiest way to make massive power. It is a hassle that’s for sure but if your a car guy hassle is just part of the game. You could run low boost and be fine but I test the limits and slowly upped the boost until something broke and now I’ve rebuilt the engine to overcome the issues that stopped me from going higher then 14psi but with the time and money I put in personally it’s not worth it but I pave the way for other people to be able to boost and know what Theyr getting into then they can decide if it’s worth it and for most ppl It’s not 🤷‍♂️ but for a select few die hard car guys it is 💪😎 built not bought isint for everyone lol
