Swapping for 450cc injectors.

[yukondoit]

Would it be worth it to swap out to 450 or wait and get 550s, if not how high can i boost on the stock 390's before havin to swap. thank

It really depends on your goals. If you're shooting for less than about 270 at the crank, 450's should be sufficient... (you can run a little more with an adjustable fuel pressure regulator.) Plus, you can't beat $50 off of ebay.

Im sorry but i was under the impresion that our cars (95-99) came with 450cc injectors stock as well as some of the 1g's. And as i believe that this is true trading your stock 450cc injectors for new ones would be rather pointless.

correct, all 2g's, auto or manual have 450's. If I remember right I did the math in maximum boost and a set of 390's at 100% duty cycle would be good for about 250-260hp, but that's with no room for error. So now I have a question, how much boost should I run safely on my 390's with a small 16g. or just leave it at stock psi until I get my AFC to tune for my 550's.

Wait for 550's. Perhaps you should read up on this before you get too into it all. http://www.dsmtuners.com/tuning-guide/2gturbo/ Just some notes from there I thought I should point out: If you plan to upgrade your turbo you'll need at least 550's, and you shouldn't go past 16 psi with a stock fuel pump.

AHhh didnt relize that 2gs came with 450cc, thanks for the info on that, yea i've read of the free mods and other stuff a couple of times as to try and figure out where i want to go. I was thinkin around the 300 mark at the crank enough to get me around but nothing real serious.

if you are never planning on going too big, you can stick with your 450s, but I would suggest 550s/afc/190 pump. At least with those you have so room to play around with.
