If you dont have a 3rd gen I would say go standalone and such for over 300whp on a 2nd gen , but Im still gonna safely try for it without one being I have the 3rd gen turbo and almost have all my fuel querks worked out . Stock manifolds and ic , will most definitely have wi and a few other things like a actual working o2 sensor ( mine doesent ever work properly ) and egt and oil pressure gauge and ect.ect. Just all small things like so to see how far it will go.I have a hks ssqv with the mr2 adapter and filter Love Doctor if you want to buy it .Also NO ONE HAS REALLY BROUGHT CHANGING YOUR WIRING HARNESS TO BE COMBATIBLE WITH A 3RD GEN MAP SENSOR AND ECU TYPE SETUP,any feed back onthat ? Ive thought it but backed out due to lack of money as always. I have seen as many people as I can stand do alot of so called power adders and never leave the mid 13s and 2.0 on the 60ft and that is enough to convince all thid after market stuff is hype . FWIW
