i cant decide what to get/build how does a prelude turbo compare to an ls turbo. how does vtec react to turbo's even with higher compression r they better for that sense a Pvtec-turbo/Gs-r turbo. i just want imput what do u think?

 

well, since a Prelude id alrger displacement, then you are obviously going to be able to produce more power with the same basic setup, exept that it will cost more money to build an H series motor compared to a B

 

H23 is a great platform for turbo, and i would take it over the LS B18B any time. mainly due to the displacement difference. keep in mind of course that any honda motor will not be reliable with turbo if not done right.
H22 doesn't like boost that much, and B18C will take it better. but if you're planning on fully building it, then H22 should be fine and it will put down greater numbers.
if you're gonna put this in a civic or an integra, i say get the USDM B18C1 and boost that.

 

i would say that you should reduild the h23 motor and build up the bottom end. then turbo it. bigger dispalement the better.

 

b series vtec motors take to boost much much better then an h series motor. either h22a or h23a.

i've had an h22a turbo accord before and can atest to that. i currently now have a fully built haltech 99 gsr pushing tons of hp.

the b series motors are much easier to tune, cheaper to build, many more options for set-ups, etc. for a streetable turbo car a b series motor is a much better option. the bigger displacement is truly meaningless in a street car and most race cars as traction becomes more of an issue then it already is.

 

I honestly don't feel VTEC when I'm boosting. I think that you will get the same results with the H23 and H22 unless you are going to keep the stock compression. In that case if you are going with stock compression then go with the H23. Doesn't the H23 have more torque for some reason?

 

that is based on assumption, not fact, i have heard very few horror stories about stock boosted H22s

 

thanz guys. i still dont know what i want but this has giving me some pro's and con's so thanx alot

B18C1 will take boost better, period. i know this from first hand experience. i'm not saying that H22 sucks when boosted, but it's not as good as the B18C1.
and my statement is not based on assumption, it is based on research and hours of tuning. compare H22 rods and bearings to those of the B18C1 and you'll see what i'm talking about.

 

Yep, the H22A takes boost incredibly badly in stock form.

 

no, that is inaccurate, and their are plenty of people on this board that KNOW from first hand experience that will back me up. it will not hold the pressure that a B18 in stock form will, but, it WILL take a fair amount of boost, and much more than any of you guys give it credit for

 

if i boosted an h22, i would re-sleeve them. they dont come with all that great of a sotkc internal for high boost.

 

youo would have to do it for an H23 as well....
