Ok guys im pretty new into the rotary FDs and I'm having an issue with my 93 FD. So the things that were done by the previous owner was a street port 13b with 850cc injectors on primaries and secondaries running on a Walbro 255 fuel pump and with a single T3 63mm. It was hooked up with a power FC but then he took it out ones the car was totaled along with the display HKS boost control. Ive tried to start it up with the stock ecu to see if it would've fire it up but it just turns over. But ones I plug in a power FC from my brother's rx7 stock twins it starts up but starts throwing out a lot of white smoke from the back and when I press on the gas it dies on me. And when I try to start it up again it wont start, it just turns over. What could be the issue here? Could've been flooded because it wont start again? or do i need the ecu mapped?

it could be a lot of things. Could be flooded so check the sparks to see if the tips are wet. Also it could be because of low compression in the motor, again you've to check this too. White smoke i guess is normal on startup, but if its too much and/or persists then this might be a sign of coolant leak.. And yes, you need to have a tune for your car, the power fc tune from a TT car might not be enough for your single turbo setup, let alone your non-stock injector setup etc.

Sounds like it might be badly flooded. I'm guessing the primary injectors, combined with the stock ecu flooded the engine. Follow the deflooding procedure and see what happens.

Ok. I got the car to start now. I took out the spark plugs and cleaned them. Ok now it is still a lot of smoke coming out but not exaggeration of. It has coolant. And the smell is idk mayb sweet. Ive heard from previous owner that he used premix on gas. So idk if its low compression because its been 700 miles since rebuild street port engine and never droven over 5k rpm

The smoke can be due to the flooding. Go for a drive, then turn it off and let it cool down before starting it up again. Let us know what happens.

Also, if a reputable shop built the engine your engine should be fine if it's only 700 miles on it.
