okay I have a 99 dodge neon rt it has a aftermarket 55 millimeter throttle body should I get bigger injectors?I have about 7000 dollars in motor parts cams pistons push rod bearings moroso oil pan timing gears

 

List all your mods to determine whether or not bigger injectors are needed.

 

Wiseco pistons 9.6.1,Moroso deep oil pan,Eagle ESP forged steel H-beam rods, ARP Head bolts, Chikara Header,2 Crane cams, AEM timing gears,55mm Throttle Body.

 

You don't need them unless you are running lean. Stick with the stock 19lb and you will be fine. As long as your engine isn't starving for fuel, you will be good. If you had upgraded to the 2.4 with all the mods, you could definitely benefit from the 24lb injectors.

 

k thanks

 

How do you know what engine is in a car . I know its a 2.0 DOHC

 

The 99 R/T's came with the 2.0 DOHC with manual transmission from the factory.

The "ACR" neon was designed to be raced in the SCCA.
