[delsolvtec]

You can't turn the boost on a Greddy kit any higher then 10psi without internal modification to the turbo itself. I am running the kit at 10psi on my del sol and it was hands down the best money I have spent to date.

If you want to run 10psi run the setup I have. It works great and was bought on a budget.

Apexi Twin chamber blow off valve
Greddy intercooler
greddy turbo timer
autometer boost guage
autometer air/fuel guage
b&m command flow fuel flow modifier
apexi vafc (optional, for precise fuel tuning)
bbk 255lph fuel pump
venom injectors
aem fuel rail
b&m fuel pressure guage mounted on fuel rail

I cranked up the boost and started replacing parts until the car ran good. Then hooked a wide band O2 sensor up and went to town fine tuning the fuel system and timing. It's tricky to tune a vtec with a turbo. You are going to need a dyno and a wide band oxygen sensor to use in tuning.

Also it doesn't take much time to install the turbo kit. It took me about 2.5 hours total for the turbo kit, and another hour for the intercooler. If you are going to be running 10psi I would also recommend the following, trust me I blew all this stuff at 10psi.

Arias low compression forged pistons
Total seal rings
greddy 2mm head gasket
arp head studs


My pistons cracked to pieces at 10psi after about two weeks of driving with the boost up that high.
