Hi, I plan on building my stock 90crx si engine for boost(havent got boost yet), and I have been trying to decide which pistons to get. There is a group by for wiseco pistons but on the wiseco website pdf-- http://www.wiseco.com/PDFcatalogs/20...act_screen.pdf
there is only a aplication for d16y8 and d16z, they are pretty much the same size except for comp. height and dome volume(cc).
d16y8 comp. height 30.16mm dome volume 14.cc-
d16z comp. height 29.82mm dome volume 15.4cc-

And Info would be greatly appreciated

I also plan to use eagle rods, and I am wondering what other parts I should get for high boost(12+psi), sleeves? valves? retainers? springs?

THANKS!

 

JE pistons. reinforced rods. thats a fairly low compression motor but see if you can get it down to 9.5:1. either by thicker head gasket or diff pistons. new valves and retainers, and springs. get a timing light and an external knock sensor. the msd boost timing retard is kind of decent. as boost goes up it retards more even if detonation isnt present. therefore your loosing power as boost increases vs if timing didnt retard at same levels of boost. some what safer than not adjuting timing at all but doesnt do **** if detionation is present hence the knock sensor. will retard at precense of detonation. upgrade injectors, pump, fuel rail and pressure reg. you will need an external afc to manage all your fuel. definatly need an A/F guage to monitor mixtures.
