my engines dirty but this is when i first got the car but anyways is this tpi mfi or tbi i'v had peopl tell me different things

 

That is the multi port fuel injection. I believe they had a sticker on the manifold that said "MSFI". The "S" being sequential.
TBI would be Throttle Body Injection and look almost like a carb. TPI would be Tuned Port Injection and look like a rectangle part going the lenght of the motor with tube going down into the intake.

 

alright thx a lot
