I'm building a 2.4 motor but I'm sticking with the stock turbo Till I can afford to upgrade to a Black or something along that line, Can I Use stock injectors for now or do I need to upgrade. You can see my specs in my Signature.

Another question. Should I expect a increase in power from the 2.0 to 2.4 still using the stock turbo. or just a change in drive characteristics.

 

That turbo is going to spool very fast. It will most likely run out of air to push, or will be pushing extremely hot air, in the higher RPM band. Honestly, I would upgrade the injectors before just to be on the safe side. You know for a fact once you make the turbo swap you will need them. So I would cash in on the injectors and then the turbo when it comes time.

 

The stock turbo will run out of steam very quickly on a 2.4. It will spool at very low RPM's.

I would definitely consider getting bigger injectors sooner rather than later. FWIW - my stock fuel injectors were at 119% duty cycle on the stock turbo, stock 2.0 at 27 PSI of boost.

If you run the same amount boost on the 2.4 as you did on the 2.0 - yes the 2.4 will make more power.

so which is a good set of injectors to go with like I said the FP Black is probably as big as I will go

 

1450's if running E85....

 

I had FIC 1050cc injectors on the stock 2.0 with the FP Black - made 441 WHP injectors on 93 OCT and the injectors were at 68% duty cycle.

Just methanol injection not E85

 

Depending on the size of the meth jet you might be able to get by with the stock injectors + the meth. FIC 1100s are a good drivable injector that offer you all the benefits of a larger injector without the negatives of slightly worse manners at idle or cruise.
