Default 60lb injectors for h/c car?

I have a 450 rwhp head cam and i am going to be adding a fast 90/90 with new fuel rails. my old 28lb injectors were already maxed out and i was going to switch to some 42lbers when i put the fuel rails on, but i plan on doing some forced induction in the summer. Could i go with the 60lb injectors now instead of the 42 and not have any problems? I am going to have a dyno tune once the 90/90, rails and injectors are on. I dont want to have to buy things twice but want to make sure i can run those 60lb injectors without problems.

Without a doubt go with the 60s and save some cash on having to upgrade later. Just make sure whoever does the tune know what they are doing. I had a so called "performance shop" attempt to tune my car and it ran like crap. I had to find someone that knew their stuff.

Im definately having a reputable tuner do the tune. So are the mototron 60lbers a good choice and do they work well at a low DC?

Do it to it. I ran the mototrons on several setups and they tuned out nicely for idle quality. You'll just be running a lower duty cycle with the 60's.

Nice to see another michigander in the thread. I am going to call the tuner tomorrow and make sure there will not be any problems and make sure he is confident it will drive and idle just as it did before. I am having Kirk over at Vector Motorsports in Clinton Twp do the tune.

It will drive fine. Don't forget, when we are not in boost. Its just like NA.

Exactly! With a good tune, they behave and operate perfectly. Bob
