Hello everyone.
Anybody knows anything about it please let me know.
We took my wrx02 heads of the block to replace the block with 2.5.
We ported the heads and then noticed that valves doesnt sit in place. after figuring things out we found out that both heads got diformation at about 0.2mm. the right head (turbo side) diformated more and the other one less. Strange huh?
What we are doing now is making sure that valves sit right. we make the sits deaper and change washers to adjust valves range.
anyways. anybody knows WHY did this happend and as there any right way to fix it and maybe you can give me some recomendations? maybe i need to change heads ? (that would be sucks).

Anyways. my car with the 2l block was set up to 18,5psi with sr50 and made 300whp. + i used 65shot wet zex nitrous kit (maybe this is it?). but i used nos maybe 10-15 1/4 miles runs. no more. like 2 botles total.

thank you for everybody who can answer my problem.

Andrey.

 

man go to ZEX website and see that they do make wet kit and as long as i installed it myself and i have nos and fuel lines goes into intake that i puted in myself - i am sure it is a wet kit
