5.0 TPI Injector Swap to 5.7 TPI

Can 5.0 injectors be used with the 5.7?? I plan on using the 5.0 ecm because it's a T5.

Re: 5.0 TPI Injector Swap to 5.7 TPI

When i converted my 305 TPI TA to 350 TPI i used the stock ECM and it ran perfect.. as long as you have the same ohm rating. now if you went to svo 24s i would recommend a chip mod..

the 5.0 are 19 the 5.7 needs 22's. you will run your duty cycle in the high 90's which can cause a failure which will result in engine damage. Call FIC and get a set of 22's I think they are like 125 for the design 2 and a few bucks more for the newer type 3 Bosch. Then get the prom configured by a competent tuner
