60lb or 80lb Dekas for any gas application. Depends on HP goals, but the 60's will run to 750hp naturally aspirated and the 80's to 1000hp. Knock a couple of hundred ponies off those numbers if you want to throw some boost at them.

They are ultra reliable injectors for $400-450.


What are you planning to do with your car? HP wise, fuel wise, power adder?

Siemens here. Stable and affordable.

If 80's aren't big enough Bosch 220's are basically the next step up.

Deka 60lb here. Be VERY careful of knock off Chinese Deka injectors. If the price is less than $350, they aren't real Dekas...

This right here is the first thing that needs to be figured out.

Do you want a crisp clean idle? What is your base fuel pressure, do you have a return style fuel system, what do you use for fuel filters, what do you have in the fuel system?

It's not just slap in whatever and send it.....

Plans for the car are a Street/strip build with an emphasis on street (I want to drive the car alot) but respectable at the strip (mid to low 12's).

Are you using an aftermarket ECM or stock?
