Ok those of you who responded to my last thread know where i stand as far as engine mods but for the sake of finding it I'll post it again...
2002 Celica GT 1zzfe:
255lph Walbro Fuel pump
11:1 Compression Wiseco Piston
(motor was fully rebuilt w/ all new parts)
DC sports header
Cat Back exhuast
Ok here's the million dollar question (or in this case $5,000 as thats what the motor cost), is it safe to put 5 to 7psi through a 1zzfe with 11:1 compression if you fully upgrade the head (valves, springs, ect.)? Is it safe at all? This will be a fully stripped race car so make no mistake it doesn't have to be a reliable daily driver but I also don't feel like paying to rebuild it after every race.
Some one with S/C expirience please help. I know the Greddy systems are run on the 2zz and they are stock 11:1 and are safe. Will this also apply to a modded 1zz?
