3100 Turbo Project

[thegreenmachine]

Whats up guys my name is Andrew and i have a 1995 Pontiac Grand prix with a 3100 v6 obd 1. Now I am starting to collect parts to piece together a turbo system. I have gotten the turbo, crossover, manifolds, and the downpipe. every thing there will bolt up all i have to do is port the manifolds to the d shape on the 3100 heads. not the hard part comes the fuel and the timing it is neccessary to of course add more fuel and of course retard the timing. For the fuel am open to suggestions on the fuel injectors i believe the 3.4 injectors are the same as a TGP but not sure if they will fit properly in mine, also i was thinking of using a FMU for the extra fuel i know alot of people dont like using them but i think its my only choice for a cheap way out. next the Timing i have no idea how to change the timing on a distributorless ignition system i know its run by the ecu which raises my next question what can i do to tune the computer, make the proper adjustments and such. if i bring it to get dyno tuned can they do it or do i need something. Im Open to all opinions and am excited for your responces.

For low boost, a FMU and stock timing should work fine. Don't break 7 psi though. Split Second makes a piggyback that can adjust your timing and should allow fuel tuning also, but costs $$$.

look into megasquirt, you can build it for cheap.

porting the tgp manifolds doesn't leave much material left and they could end up cracking, thats why i sodl off my tgp stuff.

a rrfpr could work, but i am looking into custom eprom for my setup

sweet thats good to hear that i can avoid adjusting the timing but what do you guys suggest as far as injectors. i want direct fit and big enough ones to handel the FMU

you don't need to go much over stock with a rrfpr, some have ran 19lbers and 22 but it will prolly need tuning for the larger injectors

if you have a 1995 vin M you are gonna run into the same problem I had with no access to tune anything dut to "OBD 1.5" Double check your vin before you go anyfurther. Other than that, godspeed and post pics.
