E-tune contact : youtube@bdalchemist.com so in this episode I compare a 4b11t and a 4g63t along with their cylinder heads. power differences , oiling system and i give my opinion on which is better. evo 8 evo 9 evo x - ยานยนต์และพาหนะ
Damn I always thought that the 4G63 was the superior engine. I didn’t realize that the 4B11 engine is pretty much better in every aspect aside from the block being weaker do to being aluminum. Which can easily be remedied by just sleeving the 4B11 block.
Love this!! I have an Evo X myself and I’ve worked for Mitsubishi as well. And I love both motors.
I honestly feel like the 4B11 is where it’s at.
It’s just as amazing as a 4G63, but it’s a more refined version. Any flaws or needed upgrades to the 4G63 was put into mind when they engineered the 4B11.
Anyone that hates on the 4B11 mostly hates it for the way it has to be serviced. Sure you got a little bit of awkward locations for certain components and bolts, but if you know what you’re doing, they can be much more easier to get the job done easier and error proof than you would find with the previous generations.
My respect for the evo 8 and 9 but this new 4b11 motors are amazing I have one as a daily driver almost to 140 thousands miles and still pulls like the first day ❤
I've owned and built both motors myself. Been a mechanic for 12 years. I personally also think the 4b11 is better. And I love the 4g63. But every point you made was dead on 100% correct. And ive echoed similar things to evo friends. Alot of people couldn't get behind the evo 10 because of the motor change and evos long lineage with the 4g63. But the 4b11 is more superior. HOWEVER I think the evo 8-9 is the best looking evo ever/car ever made. I think it looks way cooler than a 10. I love love love the look of an evo 8-9. And to be is what makes it so special. Even though the 4b11 is better engine. The 4g63 is still a kickass motor one of the best and most classic. Thanks for the video.
I was a mechanic and I own both cars, and built both cars also. I think the 4b11 makes power easier. I'd agree with what u said. Except the Evo x has the looks in my opinion but has to be the sss package. U can fit 10.5 wheels easy and the 9 feels skinny. The 10 has a better sound in my opinion more smooth.
Well CHEMIST you know me is a 4B11 man already. That's what I'm doing to mine darton sleeve, wiseco pistons, manley rods, stock crank. Port and polish head, ferrea valve train, gsc stage 3 cams on a 6466 precision. To each is own still but I'm biased to 4b11 CHEMIST. Love 🇯🇲
4b11 ftw
Love the video. Keep them coming!!!!
Thank u
Thank you for sharing your knowledge.
Timing chain is fairly easy on the 4B11. Can change it out on a driveway with not many issues. The only problem I had was re-attaching the water pump sprocket with the 3 small bolts. Ended up getting one of my kids to do it with small hands!
Lol we got a small guy at the shop for that
Great video 💯🔥👌🏽
I own a 09 X 77000km
400hp at engine
Driven Evo 7 and 8
Here is my general experience
The 4g simply feels more raw and brutal with sudden boosting feels very strong but definitely feel the lag and sluggishness in the lower rpms
The Evo X feels definitely more refined less brutal more consistent torque and power band through the revs
The turbo lag is minimal and car responds so rapidly to boost and picks up speed to fast it’s shocking After fast it spools and slams through the gears
It’s by far the more advanced faster and more reliable engine.
Thanks for the honest review m8.
Overall maximum power nice, want to see the spool rate and how long it holds the maximum torque and overall efficiency of the motors. Started to look at this video seven hour ago but the sleep was strong keep up the good work put one in an S chassis or an IS show people how they work rear drive.
BD, you are the man! You have such a way of explaining things that I myself admire! My history around the internal combustion engine is huge, and I have never come across a human such as yourself who appears to be so humble in explaining the subjects surrounding the multiple topics in relation to the air pump. I had a 05 Evo 8 MR that I built back in 06, and now I have just picked up a low mileage 08 Evo 10 GSR. Promised my wife I'd leave it alone. 🤭🤑 Would love to talk to you over the phone sometime. If possible please let me know where I may contact you at. Shop #?
Wow, thank you so much for such a big compliment. And I'm sure ur wife knows what she got her self into. U can find me on Facebook or insta "BDAlchemist" or email youtube@bdalchemist.com.
The 4b11 benefits from almost 30 years new tech so you'd hope it'd be better. I'd take the 4g63 block and bottom end, 4b11 head with timing components and 4g63 mechanical oil pump if it was even possible. Head flow makes or breaks and engine really IMO which is why honda engines have been so good at making power naturally aspirated. I think mitsu should have asked Honda for help designing the 4g63 heads, would have made for a better engine all around. I hate hate hate the timing belt on the 4g63, such a pain and unreliable, but once you've done them a few times its easy peasy. I agree with a lot of your assessment coming from a 4g63 nut.
Nice video!
Awesome 👏🏽
Thanks for the video man , very informative, people that say the EVO x is not a real EVO have no idea what there saying , the EVO x is a big upgrade , from drive train to motor , yes it’s not a drag strip king , but once you look past the fact the block is aluminum you will start seeing the upgrades it has . Your a sick man sir . But please follow and like my videos , check out my EVO x . I’m a novice channel
If you leave the 4b11 stock vs 4g63 stock I guess you could say it’s better. But once you start modifying the 4b11 is glass.
Thanks for the videos man, what would be the best way to contact you? I have a few questions.
Fb or insta "BDAlchemist"
Wow, turns out machining and changing the very core and material of an engine makes it stronger than a drop in piston and rod setup 🤯
4B11t is the best, no question. And this doesn't even get into how the Evo X 5 speed is FAR stronger than then previous Evos 5 speed!
What are your thoughts on the whole EPA spiel?
Can u be more specific?
When you sleeve a 4b11t
How is the reliability and maintenance intervals if you were to say making just 650whp and close to or at 500wtq to throw out some numbers out there?
Very good
@@bdalchemist have you had any encounters with 4b11t's using cylinder supports instead of full sleeving? There's a company that's reputable doing them in mostly Honda engines and they have an option for the 4b11t also.
@@dustin2956 those have been around for a long time. stock sleeves will support 700-750whp. they do affect cooling. Me personally i would either stay below 650 or sleeve the block.
@@bdalchemist thanks for the reply. I figured putting the supports like that would do something to coolant flow. I was thinking the factory aluminum cylinders with an aluminum deck support would cool a little better than full iron darton sleeves while adding some support for a fraction the cost. I just didn't know if it was a good idea to put that kind of faith in the stock liners with some coolant restriction. I have a journal bearing custom ported 3576 so I don't think I'll make much more than the stock liners can handle if I even get that power hungry, so I should probably just leave the cylinders alone.
What’s your opinion on 4b11ts making over 500 on stock bottom end? There’s a “reputable” Etuner that seems to be trending becuse a lot of his customers make 600+ whp. Have you tuned very many stock block 4bs over 500whp?
Yes plenty , and depends mainly on health of the motor to start with and turbo being used to get to that level. Anything below a 35 is not safe at that power level
@@bdalchemist can you explain why a 35 is the bare minimum? Is it because it limits the torque at lower rpms? I’m sure mivec tuning might have some influence on it as well
@@DTFTUNED69 yes
I ran 651hp with cams and stock block for awhile before a valve broke.
4b11 can short stroke 2.4L with 272cam very very good power band good Rev , that’s e9 cant
What's the ideal cost of fully built+sleeved+labor on a 4b11 ? Going down this road in the future for sure
Of u send me a good block and crank only, to build it that would handle 1000whp it would be around $5300-$5500
Just the built block right? Labor for putting it back and the head etc will be extra
@@mperez2496 correct
@@bdalchemistfigured lol what's the turn around time on a sleeved 2.0 build
@@mperez2496 typically 2 months
🙏🙏🙏🙏
I want to build a kick ass all motor 4b11
No turbos!
How do i do it?
Best way to do it.. don't. These motors are fantastic with boost and designed around it so there aren't really options like that. But if you reeeeeeeeally want to, without having all the extra cylinder pressure and heat from the turbo, I'd do lightweight forged internals in the stock sleeves with 625+ rod bolts, the biggest cams you can find, and supporting springs to rev the car to the moon. Like 10k+ rpm. Also, if it's in the cz platform, shed as much weight as possible. Absolutely gut it and realize you're still rolling in a 3000+ lbs car.
Come on. Turbo’s are for those who can’t build engines with this Modern Day engine it must be easy to do 300hp+ naturally aspirated
Get a Mitsubishi Lancer with the NA Open Deck 4B11 and use that as the stomping ground. It may not have the strength of the 4B11-T but since you're going NA, it wouldn't make any difference once you get it sleeved and CSS Support so I'd say start with one of those. Bolt ons will net you closer to 200whp but I'm positive that when you add upgraded Cams and get it a good tune it should surpass 200whp+ nicely!
@@Manuqtix.Manuqtix Tell me you don't know much about building engines without telling me you don't know much about building engine 🤣
Wbu do ppl choose the Honda engine when they do kit/project/swaps? The 4g6 motors consistently make more power. Buddy just did a swap on a datsun 510 never even considered the mitsu
U can get a whole k fitted Honda car for the same price as a 4g63 long block.
@@bdalchemist unless you go older 4g63 series ya, DSM 4g63's are only now getting expensive at 2k a pop for a stock engine, before you could get them all day for $500
Sounds like what you are saying is 4B11 is better if you spend an extra $1200 to $ 1600 to get it sleeved.
Lol here we go
No no, I’m good with either, I have one of each.
@@bdalchemist lol lol 😂
Are EVO X even worth buying with the SST?
Depends on the cost
Has there been any great technology improvements to the SST say for example how they've advanced the technology with the GTR R35?
@@DJ_Driven i run a 14 plate clutch in my SST and makes 700whp atm and worked fine, that was with stock ecu, reached the limit on stock ecu before having issues. now with a syvecs ecu i can push 900whp. built transfer case
@@parabpbpbp interesting can you still run the SST in the factory modes or does it have to be locked into sport mode only? Also curious who built the SST transmission for you?
@@DJ_Driven has to be locked in super sport mode, and it drives quite rough, harsh gear changes. built in aus by boostinjuice performance.
So the 4b11 gives better head Yes!! I agree ,But the 4g63 is faster . There's a reason why girl like the 4b11 better , it's comfy
my girl definitely likes the evo x better because it is comfy. she hated my 9 lol.
@@k.johnny2174 she was all sad when i said im getting another evo. On the ride back from the dealer... she was like "oh thank god, not like the last one" lol
4g92 mivec
How much for your head work?
Depending on what ur looking to do, which is based on power goals
@@bdalchemist looking for 700hp goal
@@lonewalker13 which evo?
@@bdalchemist Evo x
@@lonewalker13 u need cams , springs retainers and large turbo to get to ur goals. But for safety (not for power) I would add valve changes and mivec cam delete. U can message me for pricing
New upload this week?(:
Swarmed at the shop and dyno lift needs work. Soon
@@bdalchemist awesome! Also did a compression test on my 4b11 and all cylinder came out to be around 145-140. Would you push this engine to over 400? It has around 140k miles
Compression is the not the only factor , if all is well then yes
@@bdalchemist any advice?
Leak down, make sure timing chain is good, monitor mivec , and fuel system , and then if all is well and ur tuner is comfortable , then push it.
Funny I think the 4G63 is as much simpler platform to wrench on and seems to make and hold more power than the 4B11. My biggest problem with the Evo X platform is it's just so damn uglies 🤣 Now had the FQ400 platform been available in the USA market I would have snatched that up!
It doesn’t make or hold more power. That is a misconception that seems to linger despite the 4b11 holding 600 plus hp on stock block despite being aluminum.
@@alaskayoung3413 Well if you look at the world time attack, road race, and drag race Evo's most choose the 4G63 platform over the 4B11.
@@DJ_Driven think a lot of that has to do with the aftermarket support and knowledge of platform being much more for the 4g bc the evo died off with the x. There’s ten times the amount of aftermarket support for a 8/9 over an x.
@@alaskayoung3413 Plus as far as I have read, if I recall the 4B11 also has a Cast Iron sleeves so you'll also notice that people with upgraded rotating assemblies can still use stock sleeves because the material in them is still strong too. Take the StreetScienceTX 4B11 car for example making 850whp on stock sleeves
@@alaskayoung3413 Really ? What can u get for a 9 that u can't get for a 10?
4G63 sheep stay far away from this video. 😂
Lol stop!
4b11 cannot hold 550-600whp on the stock rods. The 4b11 stock, much like the 4g63 stock, can hold roughly 420TQ... There is NO WAY the 4b11 can hold 600TQ on stock internals. Even the stock sleeves cannot handle that much power.
i made 700whp on stock sleeves, cant take more imo.
@@parabpbpbp Torque? If the torque was kept below 420-450 I can understand. The same can be achieved on the 4G63. Although it becomes a matter of when, not if at that point.
@@KiwiTheKiwi24 516 it made. forged rods and pistons, stock crank, head bolts and fire ringed
My motor has been holding up just fine at 500+ for 2 years and 600 now going for another year. The block has even been taken to 650-690whp STOCK. With a head package ofc. So yes it can take it. Now torque obviously not. 400-450tq sometimes a lil bit more is as far as I've seen stock bottom end. A good tuner can make both high hp while keeping the stock rods happy at "safe" torque level
Sorry bro , 4b11s is just an head ache
