TO B18 or not to B18

Kunundrum · #1 03-23-2003, 06:29 PM

Ok i'm at it again... this tim i'm thinking... B18A... not just any B18A.... but a Built B18A

I'm thinking... who needs Vtec... F*ck Vtec.

I found a block for 500$ (no distributor) I was thinking to get it bored .25 over anf put some pistons in, rods, new bearings, get the crank micro polished, ballance everything.

head i would get P&P with a 3 deg valve job, SS valves and new valves springs and retainors. Crower cams, cam gears...

But don't know if i should go NA or FI...
damn... desisions desisions.

any imputs... I would like to make 250whp but also wanna make it reliable.

I'm a big beliver in KISS (keep it simple stupid) and am leaning towards NA... but can a 11.7:1 CR Daily drive be reliable ? and will that be enought o give me 250whp (~300 crank)

220hp = a need for boost

Why not just go b16 turboed? There are a couple of guys down in Florida running boosted b16's. One jrs and one a homemade turbo kit.

The JRS one did 204.5hp on the dyno without tuning. Thats running on a 10PSI Jackson Racing Supercharger from a Integra GSR.

The turboed I don't remember the power but it ran 12.15 or something insane like that. He runs RPI.com out of Orlando and he's a great guy. Check it out.

Oh ya the b16 turbo was without any engine building... none at all!! All tuning baby

What are you gonna do with the ZC?

well personally for reliability reasons i would keep the compression down and throw on a moderate supercharger.... nothing too crazy, but i think you could easily pull the kind of numbers you want with a built B18 non-vtec. if you want insight in to building a high compression forced induction motor, Sport Compact Car did a 11.5:1 turbocharged Toyota Matrix as a project car... you might be able to find the articles online or maybe order a back issue. i'll look around for some info on it. I am all for building a non-vtec motor that can kick ass. and yes, what ARE you going to do with your ZC?

i'll keep an eye out for some more info for you.

here is the page for the project cars. down at the bottom is the matrix: http://www.sportcompactcarweb.com/projectcars/

i know they talk a lot about premade parts for the matrix, but i think you could derive some tips from it about building a high comp forced induction motor.

well i say go buy a jg built block, idk i but i love jg, then jsut go buy a turbo kit. there blocks are suppose to handle 35psi. so if your only boosting about 10psi then its all good.

on the jg site, www.jgenginedynamics.com , they have dyno graphs, one is a b18a with not to much parts on it, at 14 psi on 92 octane putting down 326.3hp and 267.4tq to the wheels. so runnin around 10psi should be the hp u want. but anyways yeah, i love the dynos on that site. cant wait till i save up, i am gonna get one of those block and some boost

JG can blow me, a frend Blew one to shrapnell @ 20PSI with his Twin Skrew SC... The new Dart B20 Block he is using has taken it up the ass @ 32PSI and has remained. His SC is off the hook, I forget who makes it, but it looks tight as hell and has a built in intercooler!
