Hey...

I just have a question about low compression pistons for
my '95 Civic Si with a D16Z6. I'll be replacing my pistons next week, and I was wondering if it would be a good thing to do to replace my stock ones with low-compression ones, or to just buy a set of new STOCK ones (I'll be running 8psi with a T3). How would the low-compression ones help my setup (and would they?). Also, what else
do I need to buy with the low compression pistons? (connecting rods? etc?)

Thanks in advance,
Peter

Or maybe I can get other NEW STOCK pistons from another Civic engine (DX?) and they will fit in my engine, and will provide lower compression?

 

IMO if your only going to run 8psi i would just use some new stock z6 pistons, compression at 8psi should be ok.

 

yeah...keep your stock pistons. a lot of pro racers now days are running higher compression and less boost

 

for 8 psi keep them, but i'm going to tell you...You will be wanting more boost afterwards ... so new forged pistons are a good thing to have with forged connecting rod's. I wouldn't lower the compression to much though.
If you ain't got the cash for connecting rod's and pistons just go stock it will hold 8 psi. But if you got ---- loud of money do the swap and you'll be happier on the long run when you decide do boost higher
