I have a 93 coupe dx with a j-spec 1.5 sohc vtec motor. I have had my greddy turbo kit for 2 years with no problems. I am bored with it so I got an intercooler from an isuzu box truck and installed that, it feels better but I am going to turn the boost up to around 9psi and I am looking for suggestions on suppling more fuel...possibly 320cc injectors, turn the fuel pressure up leave it alone...possibly a afc but how will this affect the greddy fmu. :banghead:

turbod16.com forums has a TON of info (even though technically your motor [I'm guessing] is a D15b it's basically the same thing). But basically you'll definently want to upgrade the injectors and probably get a differennt fmu unit. The Greddy one is set for 6 or 7 psi so you'd benefit from an fmu that has a better suited fuel map. But you should definently consider getting it dyno tuned with that much psi; I've seen a few turboed d16/d15's blow their motors from improper tuning. Hope anything i said helps.

thanks for the info...I actually blew one motor by running 12 psi...I already had the new motor but I wanted to see what would happen. anyway thanks for the info on the web site.
