Pt-54 Injectors question

[86TType]

Ok i have a Pt-54 and stock injectors....i was wondering what size injectors should i go with? I have the built transmission with a 3500 ptc stall convertor...everything else is mostly stock! Any suggestions? Thanks

I would say no smaller than 50's...Depends on how hard you plan on running the car...If you are not running alky,And plan on running the boost well into the 20's..I would go with the 60's...That would be more than enough to cover you...If you have alky...You could get away with 50's no problem.

If you use alcohol injection and/or race gas you could just get by with 50's, if you plan to max out on 93 octane without alky then 65's are the minimum. I'd either go with the 65's (also called 60's) or if you plan to step up to a bigger turbo later go ahead and get your ecm modified and go to 72's now instead of buying twice. I ran 72's and a 54 for several years - didn't need all the 72's could do but shouldn't ever have to buy bigger.

I would get the 60 lb injectors and a matching turbo tweak chip. This combo will take you far and you won't have to upgrade for a long time.

10.69@125.6 on a TurboTweak Street chip (70% fuel) and 55's...No alky.

I think you will be fine with the 55's...You need to add more fuel into the chip...If you are running a TT Chip.
