Couple of questions

1. Which is the better tb and plenum setup to go with for a 99GT 70mm or 75mm???

2. At what point of modding do you need to go with bigger injectors? Can you do all the basic bolt-ons and not need bigger injectors with no problems?


Thanks for the help guys!!
 
That depends on the plenum. there is no universal rule. c&l 75mm, accufab 70mm, trickflow I think flows best with 70mm can't remeber what the dragon worked best with.

injectors will hold up to 300hp+ so you should be fine. the best I have seen with all bolt on's including cams, bullit intake, and everthing but the kitchen sink is 300 on the nose. rule of thumb I have heard is like 315hp+. basically I would consider injectors if I was running, heads, cams, longtubes, intake the whole nine. it is a point that I am sure could be debated.
 
ok good thats what I thought for the injectors but I was watching that show "tuner transformation" on speed channel and they were ricing out a civic and all they did was a CAI, and full exhaust headers back, and they upgraded the injectors.....just made me wonder....but I guess they are a bunch of morons on there...
