What am i gaining from my 9.2:1 stock pistons to the p30 11.5:1 pistons in my stock lower end? just a stock rebuild not bored or anything...

 

2.3:1 more compression lol

 

lol no ****... but hp numbers torque numbers?

 

nothing but trouble without a tune.

 

higher comp ratio=0 hp. you need cams too

 

there is not a number anyone can put on this, period. It all depends on the tune, what other supporting mods you have etc. maybe look into this a bit more before you make any decisions. i assume the b18 is a LS? if so you will want cams for sure or you will want cams for sure or you are just wasting time

 

70mm throttle body, ported and polished intake... what should i run for cams... i cant go to extreme its in a racecar and everything supposed to remain stock but they dont know what they are looking at... whats a mild cam thats gonna help me gain a little hp and ft lbs?

 

wait...so you're cheating?

 

id like to think they're idiots but they don't even pop your valve cover to check if your doing just that?

entry level cams would work.

and no one but a dyno will tell you the numbers.

 

they can pop the cover but if i do regrinds they wont know the difference, they dont know what they are looking at everything i race against is mustangs pintos and probes... there is a dyno close by... whats your opinion on tunning with hondata? and opinion on what program i should go with or custom?

 

I just wanna know... are you building a LS? if you are save your money, throw a vtec head on it and be money and power ahead from the get go.

 

hondatas good.
ask the tuner at the dyno what he thinks you should run. they'll know more then me.

 

yes im running non vtec ls... but ive swapped tranny to 92-93 style for the gear ratio on the track... i turn 6800 at the end of the straight away in third... swapping to a vtech head is going to change my power band that im in right now correct? its going to want more rpm???

 

Ill take back what i said. UNLESS you put ARP rod bolts in the bottom end a Vtec head wont do much for you other then cause problems, if you did that though you could turn 8200 w/ a stock vtec head and make alot more power, plus top end will kill on the track.

 

but tire size is whats gonna kill the car... the size of what im running now is as small as i can run... and im only turning 6800 rpm now... i dont have tire means to twist 8200
