Top 20 Cl Dyno Pulls

Good luck man!

Just for reference... one of my buddies bulletproofed and built up a B20/VTEC setup for turbo, and he only made 170/140 at the wheels without the turbo. That included a port/polish from Endyn, turbo grind cams, 9.3:1 compression etc- so you'll probably come in a bit lower than that.

i doubt it...my compression is gunna be around 9.8:1 port and polish with type r cams, jg intake manifold golden eagle fuel rail, aem fpr. but im not really concerned with the power without the turbo. when the motor is done im hoping to put down somewhere in the neighborhood of 450-500hp at 22-25psi. shouldnt be to difficult but we will see.
Oh and about your b20 i wouldnt expect that to last long, sleeves are much to thin plus the are siamesed which is why a lot of pros dont use them. you would be better off buying a gsr bottom end and sleeving it, then boring it out to 84mm even then your pushin it for turbo. you gotta think about cylinder pressures when your building turbo motors. a lot of the turbo motors we build, we keep right at the stock 81mm bore or go just a little bigger(82). However these are on sleeved bottom ends, not stock sleeves.

84mm and boost on aftermarket sleeves is perfectly fine. Hell, I've seen STOCK b20 blocks hold 18-20psi for track days, 14 daily driven...for extended periods of time.

lol ok...personal thing...i dont like it, id much rather have reliability. besides id have to call bs...your talking about something a sleeve that is thinner than a stock b18's and can handle more? ask anyone, a stock b series sleeve is NOT good to 20psi reliably. period.
look at my sleeves, then look at a b20;s and tell me which one you would rather have?

Uh, like I said... he bulletproofed and built the engine. That means the best Golden Eagle sleeve setup he could get, coated forged pistons, custom cams, custom port/polish etc... tons and tons of crap. He's shooting for 500whp minimum. Running the stock sleeve to me does not constitute bulletproofing an engine for boost.

And like I said- if you're running the stock bore, you're going to put down less power under boost, even with Type R cams (probably less aggressive than his) and a half point higher static compression. You've got more than 200cc less to play with.

Damn straight. An unmodified B20 can still handle quite a bit of boost. I've said it a thousand times- they're not made out of glass.

Thicker is better, yes- but that doesn't mean that the thinner siamesed design it a total piece of crap like all the bandwagon jumpers in the Honda world like to believe. Stock B18s have no problems running 20psi at the track either- you just have to know what you're doing.

Yup. I was just making a point- both you and my friend "R" have built engines for similar goals, but his put out a certain power level, and is 166cc larger than yours. The logical conclusion is that you would make slightly less power because of displacement- half a point of compression won't help you overcome a 9% displacement deficit. I'm not trying to bash your engine building skills or parts choice- just making an observation.

Good luck on the dyno.

I never said I wouldn't RATHER have an aftermarket sleeved block, but you seemed to think a stock turbo b20 wasn't possible, and even 84mm aftermarket sleeves weren't enough for boost. You can call BS if you want, but people know it's possible, and it's been done. Shame you didn't know. Stock B series sleeves, on the B18 and B20, have been taken to 20 psi for numerous track passes, and run 14 on the street. I never said the B20 sleeve could handle more than a B18, that's simply the way you took it because of your "beliefs."

[Hybrid_Coupe]

i never said a stock sleeve motor, let alone a stock b20 turbo isnt possible. i said i dont like b20's because of their siamesed bore design, thinner sleeves and what ive learned from seeing a b20 crack sleeves under boost.
Now, as for a golden eagle sleeved, b20, thats a totally different story, that would be just like running any other sleeving. My block is JG sleeved, that would make it the same as my block, just with more displacement. now the one difference, what crank is he using? the b20/ls crank? you people seem to forget, the main prob. with ls/b20/vtec motors is they lack rpm. now a built one can handle more rpms than a stock one, yet i still dont believe in a high rpm ls/vtec. id much rather have my gsr built to go to damn near 10,500.
I dont understand why you want more displacement anyway, you seem to forget, that my buddy made 536whp at 23psi of boost. and that was on an 82mm bore. And you know what, last night we built an 84mm 12.5:1 compression all motor car, with thicker sleeves than mine. I just dont like the idea of 84mm and turbo. you guys all jump on me for not talking civilized, your all jumping down my throat, because i tell you i dont think something will work. maybe you all need to learn to take your own advice. hell im gunna stop helping you people so youll learn from your own mistakes.

He's using the B20 crank. There really isn't much difference between the GSR 87.2mm crank and the B20's 89mm crank- the change in static cylinder wall loading is only 3%. If you said that your engine was going to displace 1834cc at 81mm bore, I assume that you're running the 89mm stroke also.

Why not? More displacement = more torque = more power at lower revs. That's a good thing.

Sure, if you like thicker sleeves, that's fine. I never jumped down your throat- just made a simple observation that you would probably make less power off boost than a similarly built engine with 9% more displacement.

Calm down.

[Hybrid_Coupe]

alright sorry, i guess i got a little butt hurt there. my bad. i know there are different views on building motors. i just like to add my 2 cents in. i know its not the only way to do things, and your prolly right, i will make less torque. but i doubt ill make a considerable amount less horsepower.
oh no im not using the 89mm crank, im using 82mm pistons. i think it makes my displacement something like 1832 or something like that...im not exactly sure. ill do the math in a little bit.
