I'm looking for a TPI setup to change out my 92 RS it has a 305 TBI how hard is it to change out can you guys help

esc

AlDixie did that swap recently.
If I remember correctly he repinned the origional wiring harness to work with a TPI computer. But he could tell you a lot more than I can.

Do you have any of the parts yet?

Yes I repinned my TBI Harness to work with the TPI speed density setup. Its fairly easy to do. I still have all of the information. Requires you to lengthen a couple of the sensor wires and of course add the extra injector connectors.
Quite happy to pass the information on.

Yes please can you send me the info at talsma2007@yahoo.com also does it matter what year i get the tpi off of and will it end up being speed densty or maf. thanks justin

Late 90 thru 92 is speed density, easy to tell just look for the 9th cold start injector on the drivers side of the manifold. If it has it then its MAF, the MAF is more forgiving is your using a bigger cam. I used a speed density setup, there are a couple of guy's on here who can do you custom proms if you use the speed density and want a more radical cam. The only other change to do on the TBI engine is you need to change the knock sensor as its different between the TBI and TPI. Also to get the electronic speedo working you have to put a jumper wire from the VSS (speed sensor)I'll gather all my info and email to it to you.

It also helps if you have the factory manual, I should be able to scan in the required pages this weekend.
