on my 84 242 turbo, i"m getting ready to fix the exhaust along with some oil leaks and start driving my car. going to pull the engine to address oil leaks. the B21FT has 142,00 and in good shape. my question is turbo size. i have a new Garret T3 that is oil cooled only with the compressor 2.75 inlet and 2" outlet. its a 4 bolt outlet turbine /76 compressor trim 57 and .63 A/R. i dont know turbo and is this too big for the little B21FT? . car is on megasquirt but not tuned yet. going 3" and two muffler and no cat. also got a good 16T that i figure might be a better choice for a driver. Thank for any advice.
 
Should be fine. The powerband won't be hugely different from the stock TB03. Definitely worth using a 90+ exhaust manifold though.
