450cc injectors on a n/t with 13G turbo ?

[94tealtalon]

I'm installing a 13G turbo on my 94 non turbo 4g63 engine. Would it be safe to run 450cc injectors ?

I think you mean 13G.

ya I meant 13G...


thanks

Stock 13g auto cars came with 390's so I hope you have an safc to tune with..OR a 5 speed turbo ecu, to use the 450's..

I have the 5 speed turbo ecu. I was told that the 390cc injectors might run to lean.

Ok heres the info you did not know..

1g auto's came with 13g turbos,390 injectors and 42ish psi fuel pressure.
5speeds came with 450 cc injectors and 38 psi fuel pressure..

But vfaq says 1g fuel pressure is 36-38 psi..So I could be wrong

If you run the 450s and 5 speed ecu that ecu will be tuned for the 450's..So running the 390's on a 5speed ecu will cause it to run out of fuel..

I was going to use the auto turbo ecu if I went with the 390cc injectors.

Someone on this site was telling me that my n/t motor has more compression than a turbo motor and if I was going to turbo my n/t motor I should take it easy if I used the 390 injectors because it will run to lean.

Basically if you run a turbo on n/t compression..Don't expet to run 10 psi..Id say 5 to 8 psi..Or you risk blowing your motor to hell...You can run a turbo on higher compression but low boost is the key..On a 13g you should be happy with 5-8psi..Not to mention the basically idle spool(insta spool)..They spool super quick if your didn't catch that one..

This link is good reading if your going to go through with it..

Have to do something with the ECU with this.

For the stock ECU will think that the stock 240's are still in there. You drop 450's in there and they'll still be putting out like 240's due to the ECU having control of the fuel delivery that it's programmed for.

Gotta match up stuff perfectly for things to run right.

youll be fine just get a good tune afterwords.
