Boost and timming Problems HELP
Just Bough a 1987 RX& with a 91 T engine on it, Have it for 5 months and blew a rotor and a Housing. Invested 1500 in all brand new parts for the motor small street port and in the 3rd week just Blown Engine yesterday. I Notice the boost was droping over 12 psi with almost no efort.
So I'm Going to fix it again, How can I prevent my engine from blowing off,
1) Is a Manual Boost controler Enough?,
2) How to control the fuel to run rich?
3) What about timming, Heard the computer goes crazy on timming after certain PSI
4) And last but least important FDC, where can I buy one cheap and I guess is one of the problems that kill my motor?
Will apreciate your comments. and Sorry About the TIPOS..

PLease read the various FAQ's about rx-7's because it will answer many of your questions in depth.
My first guess would be that you have many mods but have not looked at your fueling problems.
1. They cannot lower boost to a safe level, only raise it.
2. With a computer like the S-AFC or many others.
3. The stock computer is good for running stock.
4. You mean an FCD? Look online and yes, it can kill your engine indirectly.

Invest in a wideband sensor/monitor if your not going to take it to a dyno shop.
Keep the boost down to ten psi if your not going to get a standalone computer.
Like they say.....a boost controller can only raise boost.
Do the fuel pump rewire.
Buy a Walburo if you must. It seems to me a safc is good enough if you keep it down around 10 with the stock turbo. Intercooler intake temp are extrememly high even with a stock turbo running around ten psi. It gets in the two hundred degree mark under long boost sessions. Beware.
The guy with the supercharger in the other thread has not even put a intercooler on........yet. I wish he'd monitor his intake temps, but that won't happen. They're a lot higher than he/they think with a supercharger.
