Default what injector size?

Ok, I have a 98 formula with the factory fuel injectors still.

I'm getting ready to install a heads/cam setup with all the bolt ons. ( ls6 intake, 80mm bbk throttle body, long tube headers, etc.)

On top of that, looking to juice 100-200shot. (nx works wet kit)

What size injectors should I go with. I was going to go with 38 lbs, they were a great price, but after doing some reading. 42lbs, but than they might be too small too.

Should I just get 60 lbs and not have to worry about it again?

All I can tell you is that I have 36s in mine with fast intake and headers and the highest duty cycle I can get them is about 60% and they should be good up to 85 percent. They stockers were running in the low 90s before I changed them. I'm thinking 42s will be fine unless you find a way to suck in a lot more air.

Do the 60s and stay ahead for the future. The price is almost the same. I did it backwards. Which in the end cost an extra 450.00.

If you are going to stay nitrous, then 36's (red tops on a ford car) will be fine. 60's would be way over board. Now if it was a dry kit you were spraying id be all for the 60's!

Brid does have a good point. My ocd azz wont stop adding parts. I've been modifying my junk since I bought it brand new in dec of 01. And Im still not done and may never be! So if you see yourself wanting more.... think about what you want for a little while.

I have a set of used 42's. If your interested PM me. I would say if your not going FI, then 36 or 42 would do fine. Unless as stated, you go with a big dry shot.

I'd also go with the 60's also, I've seen way to many people have to do it twice. Bob

Looks like I'm going to a turbo setup now.

so, I will probably go with 60-65lbs just to be on the safe side. Hell, I might just do 75lbs for the hell of it since they can be tuned.
