ITB's

[ZedEx]

yeah. ill be building an all motor b20/vtec later on down the road. i like the idea of ITB's but the motor is probably gonna cost 8k(including tranny) to build so i dont know if i wanna spend another 1200 for ITB's if i can get the same power for 1/2 the price w/ a normal intake man.

thanks for the help guys

For $8,000, you can build a pretty decent all motor setup... I wouldn't be as quick to shoot for 250whp though, that's a tough number to hit with a B-Series. If you had twice the money, I'd say it wouldn't be a problem.

16whp gain is teh hawtness

The Performer X manifold is all over the place on honda-tech, and yes, that was with just the manifold itself. Aerodynamic technology has come quite a long was from where it was 5 years ago.

Pretty much.

c'mon man how much are u looking to push out of the b20? boost is the way to go baby.ITB are not my favorite unless....i can't even think of a reason...but feel free to do what u have to do. just 0.2cents buddy.

see ya 240love.

You obviously don't know the first thing about all motor Hondas... For example, RPRacing's 230whp all motor Integra Type-R ran 11.98, in a full weight Type-R. Now imagine about 240whp all motor in a CRX.

230-250 . im not gonna half ass it. Stage 4 block http://www.exospeed.com/category.php?id=144

fully built head

and maybe a turbo after that if im not happy..... and hell, ive got a crx so it wont take more than 250 to put me in the 11-12sec qtr mile range

Don't waste your money. Just come up with a block and a head, and call RLZEngineering in Concord, NC. They've built many 250-260whp all motor B-Series in the past, one for a friend of mine for his Type-R.

I guess your a hella driver then LOL

You're acting like that's unobtainable? 210whp would put him in the 12s, no problem. Look at what CRXs are doing with stock B18C5s, low 13s, high 12s, with about 170whp... Just do the math.

hmmm

...when building an engine for NA it eventually gets to the point to where you have to go with pistons. And the only way you're going to get any kind of decent power is if you choose high compression pistons to go with a nice set of agressive cams.

Sure, go ahead and do that. I did

But after that, any kind of FI is out of the question on that block.

you should be able to tap mid to high 12s with the right setup in a CRX.

Well, keep in mind, you don't want too high of CR. Typically, with decently aggressive cams, you'd want around 11.5:1CR, no higher than 12:1CR. Example, a friend of mine dyno'd IDENTICAL Type-R engines with Skunk2 Pro-Is, with CTR pistons (12.5:1CR), and P30 pistons (11.4:1CR), and guess which setup lost 4whp due to it's CR? Yeap, the setup with CTR pistons.

Sometimes less is more, especially with all motor Hondas.
