Final setup - LQ4 98 Firebird I have asked this question before but the setup has changed a bit. Just finished up under the hood on my crapbox firebird with a 200k mile lq4. Has an Elgin 216/220 .561/.561 cam, LS1 intake, long tubes, 42 lb injectors, and will be on pump gas (87). 60e to stock open diff 10 bolt. Stock ls1 f body air box. This used to be a v6 car. Take a guess! I would be happy with 350+ whp. Might need to do a higher pump gas setup, but would be nice to use 87 or 89. |
This might get there, but you would do yourself a HUGE favor getting an LS6 intake manifold (either OEM or Dorman). The long tubes will help a LOT, not sure you need the 42# injectors, but they won't hurt as long as it's programmed for them. |
I am just using rebuilt S/C 3800 injectors. They are about 42lbs at 58 psi. The stock truck ones I hit 107% duty cycle at 6000rpm. The intake I got for $150 to my door. So that will be fine for me. It's an ice cream family cruiser. My plan in the future after everything is done is to do a LS3 top end on it (intake and heads). |
