When do I have to upgrade injectors?
I plan on camming my car, prolly gonna make around 370-380 RWHP....How much power can my stock injectors support before I have to upgrade them....Also, same question for fuel pump.
My car is a 2001 TA.
Thx

I wouldnt worry about upgrading the injectors until over 400rwhp, so you should be fine. My car has heads and cam and still uses stock injectors although when I put my Fast 90/90 on this week I will be upgrading to 42# injectors.

small cams and bolton setups need 30s (redtops, really flow 34.6 at the stock 58psi fuel pressure). bigger setups need 42s (greentops). for example my car with 364rwhp ran 85% duty cycles on redtops, but a friend of mine got them to do ~430rwhp but it was running out of fuel so bad you could see both AFR and power output flutter on the dyno graph--dont do that
