Hi,

I need i little information if possible.

Can i put B18B1 pistons into a B16A2 block with the same bore size (81mm) ?

Thank you.

yes. but your compression is going to suck.

Boosting?

ek9wannabe · 01-16-2007, 06:01 AM

maybe, it will def. lower your compression. but if your replacing pistons for boost, wouldnt u want to use forged over stock cast pistons?

DeeDjay · 01-16-2007, 09:56 AM

Yes its for boosting

I only want 300wph and it will be dispendious to put forged for only this power.
The pistons that i have is for boosting. Flat head

I'd just use the stock b16 pistons for that kind of power level.

If I were choosing a stock piston, I'd probably go with a P72 GSR piston. The B18B pistons will give you a compression ratio of around 8.5:1, which is good for running high boost, but not for your setup. Since your goal is only 300whp, youll be running relativly low boost, and will want to retain as much power OFF boost as you can. With an 8.5:1 compression ratio, your car will be slow as piss until you get it into boost. a 9.5:1 compression ratio would be optimum. The USDM P72 pistons will give you a ratio of 9.1:1, and the JDM GSR pistons will give you a 9.6:1. Thats your best bet.

bleh, you can make 300whp with stock b16 internals easy with a good tune

lol boosting is for whimps..

besides..if ur only aiming for 300whp..lol its very simple to hit that on a stock block ls and a stock block b16..
