If I were to drop some 9:1 pistons in my B16A, is that going to dull the engine significantly pre-boost?

Also, what about putting some in that bring it down to 9.8:1 or thereabouts, and putting a thinner headgasket in (I know, they contradict each other) so bump compression up to 10:1 or thereabouts. The engine would then have slightly lower compression and more abusable pistons, would that work alright?

 

Yes, you will be slower.. Is that your question?

 

you're not going to notice a difference dropping to 9.8:1, especially once boost kicks in.

 

any more?

 

why the hell are you putting thinner headgasket on it if you are going turbo?

what the ****? why are you boosting if you are gonna bring the compression back up to less than 1 point below stock?

put it this way, if you do to that, you are gonna be limited in the amount of boost you can run, so its gonna make your car ALOT slower than the little difference you would feel with 9:1's before you spool.

 

I don't want to go high boost- and if y'all read I said I was just askin' a hypothetical question to end up with heavier duty pistons and only slightly lower compression, a yin/yang sort of thing, I didn't know if that would work, 9.8 pistons with a hg that ups it .2 to 10:1, what's with HT? Someone asks a question that may not be plausible/possible but legit nonetheless and people step all over them, then someone asks what f*ckin' interior teg piece can go into a fugly hatch and everyone trips all over themselves with an answer.

 

If you're not going to go "heavy boost" why would you need pistons that are desgined to hold up to extreme heat/boost/horsepower? Just run your stock ones and leave it at that.

 

if your not going to be running high boost then you dont need to lower compression as long as you have a good tuner you still might want to get stronger pistons but you dont need to lower compression

 

I was under the impression that forged pistons could take a beating day in and day out.

So can stock ones. But if you get some aftermarket forged ones with a shitty tune and some stockers with a good tune on the motor, I'll bet you that the stockers will outlast the forged ones.

 

Might want to fix your signature there CaptivaBlue... if you don't know what's wrong with it then... for you.

Shhhh......if he doesn't know then don't tell him.

is this b/c I called it JDM b16a2 rather than second gen obd1 B16, if so, Grow the F*CK up for Christ's sake- if you knew what I meant then why does it matter?

 

Its gonna be ok. Just take a couple deep breaths. We were just playing around with you. Don't take it so seriously.

Not to mention that whole "weakest link" thing, If you upgrade just the pistons it will only make hte pistons stronger, If that's the weakest link you can run more boost till it detonates and messes up everything else :D.

BTW the whole lower comp pistons higher compression combustion chamber is the exact same as just getting equat comp pistons. It doesn't matter where the compression comes from it's the same. Just if you mill your head your timing is retarded and if you get thin headgaskets it's the exact same as milling your head just differnt way to do it. .

it does matter because there was no jdm motor with the a2 designation, and the b16a2 is obdIIb, not obdI.

 

if that's what y'all stress your lives over, maybe you should sit back and evaluate a bit- but to all that gave some good info, thanks
