KA Injector Swap Question

I think I might have a injector going bad, so I while I was at it I was going to swap all the injectors out. There are some 300Z (370cc) injectors that I might pick up, 100cc bigger then the KA24DE (270cc) and order a pressure fuel reg. I'll have my full exhaust (header back), bigger intake manifold / TB, slightly bigger fuel pump, and cams later down the road. Just asking if these injectors will work on my KA24de

Not without tuning for them. Also, you don't need an FPR unless your stock one is going bad. Even then, an OEM regulator will be fine.

what you the best way to tune them with out spending $100's of dollors? On a pretty tight budget now cause I'm buying my GF a 2008 Saturn Outlook (Chevy Traverse) for Xmas. That is costing me a pretty penny. lol

Best way for you to stay within budget is to get a set of OEM injectors and leave it alone.

I've always been a guy with the normal bolt-ons, but I lean more to motorcycle. But thanks for the answer. I need to be wasting money on $h!t that not going to do anything for me. OEM injectors, but I did order the FPR mainly for the gauge. lol

Leave your FPR alone and cancel your order. If the new FPR is not set exactly like your OEM, or does not react exactly the same way in dynamic conditions, it will require remapping (and you dont want that either).

The only thing that the gauge will get you are leaks and problems. I guess you did not buy an aeromotive or any 80$+ FPR , did you ?
