Has anyone ever swaped their TBI system to a TPI set up. I want to what parts would i need and how hard the task would be. I will be pulling my engine this winter to rebuild along with the rest ot the car. I have a 1992 Camaro RS 305 TBI 25th Anniversay Heritage Edition. Red with blacks heritage stripes.

 

Welcome to TGO!

Yes, it has been done many, many times and is a pretty common swap. There is a pretty good tech article on this on the main page, check it out first:
https://www.thirdgen.org/newdesign/tech/tbitotpi.shtml

After that, try a few searches. All the info that you will need should be in past posts from people that have done this before. It's a common swap, so you should have no trouble finding out what all you need. If you still can't find answers, then post questions. The TPI board might be a better board to post in though, considering most of the guys here are sticking with TBI.

 

hope youd going with some diffrent heads and cam

 

so are they saying u cant do a tbi to tpi on a 1989 IROC is that a common swap ????

 

They are not saying you can't do it, but simply WHY? The TBI is not a restriction on a stock engine! Why spend more to get the same. Headers, Full Exhaust, Cam, Heads, and Chip work are the keys to power on your TBI engine. All of which are not going to be changed with TPI.

 

im buildingt my first 383 for my IROC so not sure if tbi or tpi is best

 

TBI is great, but for a 383 you'll have better luck with a TPI harness and ecm, just get a better intake.... "just MO"

 

i need some opinoins then i have 1989 IROC 305 tbi 5spd ,gonna build 383 with t56 ,shoud i convert 305 to tpi now , or should i wait till engine swap heard its good to get the bugs out now then swap should go smoother ,thanx in advance

 

with a big cubic inch motor, I would not go with TPI, Something like a Stealth Ram would be better. (unless this is going in a truck, in which case TPI woudl be great, as the long restrictive runners are great for low-mid RPM torque.

 

Dewey, thats what i was getting at when i a said diffrent intake....
