- We are guessing this is the highest hp RB20 in Georgia, maybe the south east? If not who cares it’s still fast! Brett has been watching us for a while and decided we were worthy to work on his pride and joy. He had us do a full engine build with a 450-500 hp goal in mind. We actually exceeded that goal making 517hp/428tq on 25 psi running e85.
Mod list: 9.5 compression built block, built head with over sized valves/springs/Kelford cams, Garrett 3582r turbo with internal wastegate, 1000cc injectors, 450 pump and Haltech ecu! Now for the crazy part, the engine is running the following stock parts: turbo manifold, intake manifold, throttle body, fuel rail, fuel line size, fpr and trans. You don’t have to over do it or upgrade everything to make lots of power. We think there’s more on the table but we’ll stop here for now. Thanks Brett for letting us work our magic!

Heck yeah love these kind of videos u guys really do work magic! That’s one badass gtst
That's impressive... Can't wait to see what can be pulled out of the RB26. Keep posting and keep [safely] pushing expectations.
They're gonna be building and tuning mine later in the year!
Loving the stock intake manifold. I did the same in my S13
Keep it up countersteer does good work
Best shop around
Awesome video
That RB20 sounds nice!
I love your work bro 👏🏼👏🏼👏🏼
Huge props to y'all
Thank you!
New subscriber here from Florida . I love how methodical you are w your vehicles.
Have a r33 hopefully on the way to driver motorsports and want to get it to 325/350 but man these damn things are expensive to get there safely lol.
I can always hope though. Keep up the skyline vids!
Thank you! We will be tuning at Driver the end of this month :)
Can't wait for my build dylan
Hear such good things about you guys in outsiders, definitely wanna bring the gts4 by someday
Hey thank you! We'd love to help you with the car in any way!
Awesome R32 build, sounds like a screamer. How did you find the performance of the Kelford Cams, would be keen to hear your verdict. Thanks for installing Kelford Cams.
Love the car and especially repping the 🙌🏽 #gocanes
Will be reaching out to you for my RB build
I have one of your driveshafts going into my r32 gtst being built atm. similar motor build / hy35x (for now.)
I am a Big fan of you I like the car
Will be taking my car to you guys !
Absolutely, we would love to help you! You can email us at Contact@countersteerLLC.com if you are interested in a quote!
Just bought an r32 gtst and id love to make mine like this
Congrats! Bring it by sometime!
Semi built it sounds like, did you get all of the rotating assembly (with clutch) balanced?
Will be reaching out to you all for my RB build
I gotta hand it to you guys, you made a hell of an engine, that doesn't sound like shit. It sounds amazing. Thank you for not desecrating it with a fart can like some of those ricer assholes do. That's horsepower done right, there.
See an ok gain also if you put a bigger throttle body on it. And 10-15 more psi. ;)
Got myself a Gtst type M recently and I really want to build the rb20 but everybody says go 25 , my 20 only has 22k original miles on it so I feel like I have a great base
Where are you guys located? Waiting for my r32 to show up from Japan , should be a couple weeks
We are in Canton, GA and we would love to work on your car. Contact us by email contact@countersteerllc.com.
Nice work, turbo may be a little big. I’m making just over 400 on a built 20 but I got full boost at 3500 rpm goes to 8500. That’s in aus also
What are the details of your build?
@@rleojeda spool rods, srp pistons, billet pump gears, cometic gasket and arp bolts everywhere, biggest cams kelford make. 6 boost and plazmaman manifolds 1250cc injectors and a Kinugawa td05 16g on 22 psi
Is it okay to over build the fuel system like get 1000cc injectors but run a low DC. Just rather over build incase I wanna increase power eventually
Yes it's ok to run 1000cc if you don't need it all at the moment. We don't suggest a smaller size very often to be honest.
Currently building a gtst r32 going a different route but do need help with a tune I’m running a nistune type 2 board for the ecu.rebuilt block new water pump new oil pump aem fuel regulator 550cc injectors 255 walbro pump z32 maf stock intake and top mount mani for the turbo I’ve got basically a gt3071 but its billet built by a company named Arashi im only shooting for around 350~400 to the wheels love to get some ideas on where to go for tuning down here in KY (I don’t mind to travel I’ve got a truck)because nobody can tune on nistune but ik your running haltec just thought maybe you could help me out but it’s jus my luck i guess love the Build got a sub.
Hey shoot us a email and we'll see what we can do!
I’ve got a 20 on about 22psi.. making 371 on Nistune and ethanol. What plugs/gap are in that thing? I’m getting a bit of spark knock..
nice
Hey Bryce, We use NGK BKR7E and gap to .022". I doubt your plug type and gap are causing spark knock. It's hard to make these engines knock on e85 even if tuned wrong. Maybe the knock sensors are bad, faulty wiring or your timing sync is off. Also make sure your ethanol content is 65 or above.
@@dylancrumley1559 hey thanks for the response.. I meant to say spark blow not knock 🤦🏼♀️ I was only running a walbro 255 and I fry them every once in a while. Switched to a Bosch 300lph and mounted it closer to the tank. She’s ripping again 🤘🏽swapped from BPR7ES to BKR’s as well 🤙🏼

Do they have oiling issues like the 25/26?
As long as you have a long nose crank collar, billet pump gears and loctite pump screws there are really no oil problems. Head drains and sometimes over filling the oil a little keeps pretty much all these engines happy under 500-600 hp. Once you get higher than that a better baffled pan is recommended.
What size is your intake piping ? And where did u get the split fires
Pre turbo 3" I believe and charge piping is around 2.5 to 2.75". We no longer use Splitfire coils, only R35
@@countersteerllc9009 what size are the intake couplings to manifold ? Also 3” ?
Was he running the stock transmission for this build?
Yes he was for about 7 days and the RB20 trans blew up lol. He then converted to new RB25 trans which we sell on our website.
Wow my gtst just broke down need a new clutch. Its all stock would like to get it built
We'd love to help. Email us and we'll see what we can do for you. Contact@CountersteerLLC.com
Just curious why not swap to an aftermarket intake manifold?
The customer wanted to keep the torque numbers as high as possible with the long runners of the OEM intake manifold. Front facing tends to drop torque and raise horsepower.
hey, with a built motor like this how much power is it able to hold? what else could you have done to get more power and how fast could you make it if you did?
I'd say we could squeeze about 650-700 hp out of the one in this car and it last a good while. To get more power out of it I'd run a large top mount turbo setup and intake manifold. For as much as possible port the cylinder head and do a stroker block.
@@countersteerllc9009 good to know, looking to build my rb20 soon. do you have an instagram i could follow so i can ask questions?
@@benibsen830 yes please follow us at Countersteer_LLC.
@@countersteerllc9009 holy shit and i thought i would be lucky to make 520!
@@countersteerllc9009 well i have a new power goal now lol!
Where did he get the GTR front bumper? I have a gtst and want to get the gtr front bumper👍🏼
We have one here in stock with front lip. Email us contact@countersteerllc.com
@@countersteerllc9009 okay I just sent you guys a email👍
25psi with that turbo on e85 with 1000cc injectors? Arent injectors over 100%DC?
That is the correct boost, fuel and injector size we ran. Only took 79% duty cycle.
It would be, pop it on a Aussie dyno and watch this only make around 400-450rwhp
I’m late to this but, may I ask what oil pump did you run on this build?
Standard OEM RB25 or RB26 housing with PRP billet gears. We sell these if you're looking for the same setup!
@@countersteerllc9009
Awesome! I will actually. Thanks for the info
One more question. You mentioned you were running cp pistons, you mind sharing which cp pistons and compression ratio you were running if you recall?
@@emmanuelbravo3061 These were ordered from Spool Imports
@@dylancrumley1559 I understand that, but there had to be a cp piston model out of the multiple options they offer, same applies for the compression ratio. I don’t think he just slapped those pistons in the block not knowing the specs, hoping it runs right.
Looks like I will just do an RB20 build, with the prices of 25s going up.. lol. How much would a 20 benefit from a stroker kit? I hear 26 rods and crank and some 82mm pistons will stroke it to a 2.4.. I love my 20 up high, but man I hate it down low lol
Since it's such small displacement I think a stroker would be a fantastic idea.
@@countersteerllc9009 what do you think i could stroke and build an rb20det for to make about 500-600
Put the money towards a 25, better yet a Neo 25.
@@WraithDeath 25s have effectively doubled or tripled in price in the last 2 or 3 years. They're becoming pretty hard to find a solid enough candidate for less than 5 or 6k without trans. Rb20s still less than 2k all day long, and for most of us are plenty capable. If I wanted a 450+ hp car then obviously rb25/30 block is the way to go, but upper 300s or low 400s is very attainable on a 2 liter
@@Michael-jq5pf Purchase an n/a RB25 S1-S2 or a Neo, rebuild the bottom end to suit forced induction, add on all the bolt ons, fuel supply blah blah you would regardless of engine choice and you would have a RB25DET that's freshly assembled for the same amount of coin
RB20's may obtain 300-400rwhp but they're a lazy engine that imo, is never worth spending a cent on
Is it possible/safe to get around 350whp without going into the motor on rb20?
We recommend metal head gasket and head studs at a minimum. You could probably do 300 roughly unopened and it would last on a healthy engine.
@@countersteerllc9009 do you think a tdo5 18g turbo is a good size for 350whp?
@@nathandouglas5323 sorry but we don't have any experience with that turbo
Would y’all be able to work on mine and tune ?
Hey Hunter! Absolutely, we would to make that happen for you. You can email our office at contact@countersteerLLC.com and we can get you a quote to have that done!
Ever tune a blue printed rb24?
No sir!
How did you test the mishimoto vs the koyo?
A customer of ours has driven the tail of the dragon twice in his R32 GTR. Once with a Mishimoto and another time with a Koyo. With his Haltech CAN gauge he noticed a 15 degree difference in temps driving the car pretty hard both times. He installed the Koyo hoping to drop his temps and it worked.
@@countersteerllc9009 both installs had the rad only in variation? Was the weather similar?
I imagine in a strip car it would not affect that much?
@@jasaircraft Only variation and similar weather.
Mishimotos pretty much low quality tbh. Heard wild storys, had their drainplug on mine and the head broke off at not even 20nm
@@countersteerllc9009 do you know what radiator you went with? On the koyorad site it only shows the RB26 radiator
Respectable number power wise , but that curve is absolutely dreadful as you’d expect from a RB20
Capable of revving high but they just don’t have any low end guts to them mostly in part their tiny bore x stroke ratio
Heads also breathe piss poorly , so you’d still ultimately had been better off investing in to an RB25
Not that its fair, but my stroked rb24 will make 700+ lol
