what is the largest fuel injectors I can put in my turbo 1998 Z24 without having to mess with my ecu??

Ummm, if you are turboing your car you are probably going to have to mess with your ecu anyway, which makes this post irrelevant.

thnx i was just wondering. cuz i know that with dsm's you can go up to 550cc without messing with the ecu

ya its not the same with a jbody, from what I have seen pretty much any upgraded injector dumping more fuel than stock will mess with your ecu, they jsut dont like it...get hp tuners ...

if you are willing to install a FPR, then you can install any size you want, just have to lower the fuel pressure accordingly. But HPT has made it so we can run stock regulators and go to as large as 750cc is what I have personally read, and I am using 650cc.


HP Tuners | Garrett T3/T04B | 2.5" Charge Pipes | 2.5" Downpipe | 650 Injectors | HO Manifold | Addco front/rear | Motor Mounts | HKS SSQV | Spec stage 3 | AEM UEGO Wideband | Team Green LSD | FMIC | 2.3 cams | 2.3 oil pump swap | 280WHP | Now ECOTECED

what do you do if you have a 96? 97 and up for hpt right?

I believe the 96 guys usually go with AFPR and a FMU, but I could be wrong.
