I have a STOCK 1993 RX-7 Twin Turbo. The key to this is that i want to get rid of the work STOCK. I have 5,000 dollars and i need to make my rx-7 a 11-12 second car. Please give me a setup on how i can make it a 11-12 second car with using about 5,000 dollars. Thanks

 

Front mount intercooler, intake, downpipe, midpipe, catback exhaust, fuel pump and ECU upgrades, boost controller, and good motor.

 

Power FC ~1200
Downpipe ~ 300 = 1500
Bigger IC ~ 1600 = 3100
Intake ~500 = 3600
Cat-Back ~500 = 4100
Radiator ~500 = 4600
High-flow cat ~ 400 = 5000..

run 12 lbs of boost..anymore then please spend the some more money on a fuel pump and possibly RRFPR....

Should be in the 12's with ease..gotta do the labor yourself, but all these are pretty easy to do

 

all you need is a 200hp shot of NOS and a new engine

 

These guys have you on the right track, you should be able to get your car in the low 12's maybe even high 11's if you are lucky. And I am pretty sure you should be able to do that for around 5,000...
