ok im hopefully buying a 87 turbo 2 this week, what are some good starting mods and how high can i safely raise the boost, money will probably be an issue i can maybe spend about $2k on it this summer, i already know i will need exhaust (im probably buying HKS i found on the internet) the turbo might need to be replaced, im thinking im just going to get the stock turbo unless i hear from you guys there are better ones for what i will be using the car for (mainly just for fun maybe do some autocross) i will most likley be buying a front mount intercooler and thats about it let me know what you think i could do....yes this is my first rx7 and i have no experiance with rotary engines but ive done a lot of research on them

thanks in advance for the help

 

For one, if you open up the exhaust system, the turbo will instantly breath easier. Without a ported wastegate and fuel/fuel control modifications, this is a bad thing. Boost will spike, and you'll hit fuel cut at 8.6 psi. If the turbo has to be replaced anyway, this would be a perfect time to port the wastegate.

These links are a little out of date, but still good overall. Some things not mentioned are the Rtek chips available for stock ECUs: http://www.pocketlogger.com/index.ph...age=1&ecu=S4T2.

 

Yeah I'd agree that exhaust would be a great first step.

 

alright the plan changed a little the 7 i was going to buy is gone now so im looking to buy a 84 gsl se, it has a lot of stuff on it already here is the list
