my talon was a 91
one thing the will limit your potential horsepower with all the boost you wanna add is the fuel delivery. i have run a few different fuel injector calculators and just to get 300 hp , it comes up with about 31 lb/hr injectors. stock are 21 lb/hr. if you are running higher than stock boost, read your plugs after a run and see what they tell you. i had to read my plugs after every run with my talon and i was only running 11 psi of boost. if the timing was too far advanced, the octane was too low, or not enough fuel, you will see a peppering on the ceramic end of the plug. this is minor detonation. which is not good. next comes the electode melting off and then pistons melt.
if you are going to race, one thing i suggest stongly with any forced induction car. learn to read spark plugs
you will save money in new parts by doing this and run more consistent times. isnt this the key to bracket racing?
one more thing, one of the biggest problems with selecting injectors is the impedence( resistence) of the injector. if its not right, you will over work the electronics . accel just came out with this list of new injectors about a week ago according to SUMMIT. our injectors are 21 lb/hr stock, if you look at the ford T-bird sc 3.8, they have 30 lb/hr injectors stock. this is a big difference in size for the same size motor dont ya think?

jeffrey10x2, I understand your need to upgrade injectors because you are used to dealing with a turbo and a Talon. But remember, your SSEi has the Eaton M62. You can't max out the stock injectors using the M62, unless you go to insane pulley'* (like 2.0) but the Eaton M62 will not handle that. It will spin too fast and wont cram more air but just create more heat. Anyways...
These cars have roots blowers, much different principles than turbo'*. The only time you should be changing your injectors is when you have switched to a whole different setup. Otherwise, leave them in, you are not going to max them out with a Eaton M62. And I believe the stock injector is 24lb/hr, the N/A cars are 19 or 21.... I think 21.

i just looked at ZZ performance website and they list injectors for the sc cars there, they said that they run 42.5 lb injectors in their 97 gtp. i know that ours is 21 lbs stock. thats like adding another set of injectors to keep up with the fuel demand.
