I would like to know if this list of mods will get me 300rwhp or higher. Also, will I be able to hang with a stock A4 LS1 car or possibly beat one. My car is a 1994 Pontiac Firebird Formula A4 car.
1. SLP CAI
2. Carsound high flow cat
3. Hooker aerochamber exhaust
4. TPIS throttle body airfoil
5. throttle body coolant bypass
6. MAC midlength headers 1 5/8
7. PCM for less power tuning
8. 160 t stat
9. 1.6 RR on stock cam 480 490 exhaust 203 208 116 LSA
10. Lloyd Elliiot stage 1 ported and polished
heads 255 intake 180 exhaust cfm using stock valves

I will also be putting in 3.42 gears to help me get better acceleration. I have 2.73 gears in there now. Also, what do you think I will run with this combination of parts. Will it put me in the low 13's or maybe high 12's with traction. Thanks

 

It should get you there, but I do not see why you would keep stock camshaft? I would at the minimum get the Hotcam, it just seems logical, unless you are trying to show something on stock cam ported heads?

 

Yea you should be over 300 rwhp with those mods. There's plenty off people that have all that minus the heads that are hitting a little over 300 rwhp.

 

With an Auto it'll be harder to hit that 300rwhp mark, but you'll more than likely make it. Like mentioned above, tap into the power of a cam while you are messing with the heads. Call up Lloyd Elliot or Combination motorsports, tell them what you intend to do and they'll set you up with the right H/C package. Alot of times you can keep up with LS1's with Full exhaust and CAI, but it isnt easy. Everything on that list seems logical, only changes I would make would be AS&M midlengths and a Madwolf tune. But thats my preference. AS&M will you some bigger primaries to grow with.

If going through the expense and work of the heads do the cam period. If you want stock manners down low try a ZZ3 cam, or the Crane 210/224, or even the GMPP 845(may lope a little), the ZZ3 cam is mellow enough that even fellow b-body enthusiasts comment on how it sounds stock, but it is still a performance upgrade.

 

You certainly should. I hit 303 rwhp with CAI, headers, y pipe, 1.6s and a tune.
