This is my setup and need help with injector size before purchase. I've got a 91 stock bottom end, b-cam, SVO y-heads w/1.7 rockers, 73 mm C@L, 75 mm TB, Trick Flow Street intake, and a 100-125 NX shot of gas. Of course I already have the stall and rearend done. Last thing I need is the injectors. My question is should I go with 24 lbers or 30lb. Thanks.

i get 42s you will install more mods down the road

I have a set of 42's, I was just skeptical about them pushing too much fuel. I quess the dyno tune man can turn them down though. Another quick question, I have a Pro-M 80mm mass air made for an intercooler set-up. It is the blow through design. Would this work on my current set up?

24s will be fine.

^^^ I think so too.

run 24# injectors, 42# is rediculous for your car

If you are planning on sticking with the current mods, go with 24s. If you are going to do some heavier mods in the near future, get the 30s

Thanks for the input. Does anyone know about my mass air question?

I dont see why 19's cant keep up with that setup... no power adder, but i assume your worried about being lean when nitrous is on, 42's are way more than you need even with the duty cycle tamed. 24's are readily available and will suit your needs.

Id go with 30's but thats jus me...
