Ok, I have a 92 Camaro L03, and I want to know how much hp I'll have after the following are done:
1) Headers(coated, of course)
2) Full cat-back exhaust
3) Edelbrock Performer TBI intake
4) New cam(don't know what kind yet)

Where would this put me? Oh yea, I also put K&N in instead of the stock air cleaner. Don't got the money for heads, don't got the money for new TBI(yet) Just wanna know where I'll stand when all is said and done.

If you're digging so far in might as well grab soem TPI heads to port and poslish and throw in. Pablo spent $150 on his heads if I remeber right.

Full exaust and open element should get you 230 HP but your HP and torque curve will move all over so you'll probably need gears.

 

Ok, but what about the cam and intake? I've heard that they make a "seat of the pants" difference. So how about gears? They're expensive as hell aren't they? I'm only 17, so unless my engine is going to die without them, I'd push them off until summer at least. Also, with all of these mods, am I shortening the life of the car? Just curious, because for a car that was meant to have 170 hp, and pushing 250+ might be bad for it, but i've seen worse done(i.e. 400+)
Thanks man

 

Yeah, exaust is a very good mod for our cars. And a aftermarket cam WITH a full exaust system is even better.
30hp from the full exaust and 25hp from the cam w/ the full exaust. Unsure about the intake manifold. People have mixed feelings about the performer TBI. Some have gains and some didn't. So I am not sure.

gears are **** cheap. Go grab a whole V6 rear from the junkyard for $50

 

So, with cam, intake, and full exhaust, you figure I'm pushing about 250(probably more) right? That's very nice, but how can I dust off a 96 Cobra? Some old lady is talking trash about Camaros and I don't want to make a fool out of myself. Keep in mind it's completely stock, got a few miles on it(I think like 63,000)and she is an old woman. I thought heads were in the $800 range, but if they're cheap, I will get some. However, I am no mechanic, so I'd make sure it's done right and take it to a shop, which will double the cost presumebly(but I might have a hook up with a GM dealer)

 

used TPI heads, not new. no one wants them but they are better than what we got.

 

Yeah, installtion would be double. And I wouldn't try racing a Cobra with a guesstimated 250hp.

And these heads will bolt straight on? I won't have to add a bunch of BS onto the work order? So how does this order sound:

1) Already got Cat-Back
2) Headers
3) Intake
4) Cam
5) Heads
6) Gears
With the gears, would the V6 gears fit mine? I know I have 2.73's, but how much would a good set of 3.42's be? I don't want to lose too much gas mileage(but exhaust helps a lot I've heard, so does the intake)and I also don't want to F up the rear end of my car. Am I in danger of blowing my car up with all this business?
Thanks for the responses also

 

Well I don't think ur going to blow up ur car. But I would try getting a hold of a posi unit when u did the gears.

I'm pretty sure you'll want to do gears after the headers to match the drop in torque and the increase in the HPs RPM.

 

So with all of those mods listed above, where would I be/ estimated 1/4 mile times? Thanks guys for your help, there's so many things that I could do, but I have trouble deciding what to do next.As long as I can beat this guys stealth(he says it has 232 hp) I'll be good as gold. Plus, he says he got a gain of 35 hp from cat-back alone. I called on his bulls**t, and I was right to do so, right?

 

you could easily go into the low 14's right out of the box with all this stuff. look into the head thing before you do it. if you plan to just basically drop the heads on the way they are then this is a good deal. if you plan to put some work into them before the install(rebuild with fresh springs and stuff, and some port and polish work) make sure you get a good estimate on the price first. it may be just as easy to buy a good set of heads for a few bucks more.
the gear thing is a great bang for the buck thing. if you replace the 2.73's witha 3.42 or 3.73(this is the good one) you can expect to knock off several tenths, .3-.5 is perfectly possible. especially with a new came that will likely come on a little later.
headers can be a little tough. not hard just gotta figget the things around until they fall into place.
good luck.

If this combo can hit low 14's with traction, why doesn't anyone on the Tech board think that a 9.6 to 1, 204-214cammed, WP SR 305 headed, Headered, 650cfm Carbed 350 would go high 13's? Just curious, what cam are we talking about.

 

Yea, I want to get all of it done, but the gears and heads will be last on my list. Is that a bad plan? I've heard that the cam and intake helps a lot, so I'm going to get them purchased and installed at the same time.But I'm also going to do headers first(next). By the time I get enough money to buy intake and cam(I've heard the kit is relatively cheap) Then I'll drive on that for a while before I get heads. Gears will be the finishing touch I think, unless that's bad for the car. I love this thing, I don't give a damn if I have a TBI, I like the mileage, and it's still faster than anyone else at my school, so I don't care(faster stock probably)I think low 14's would be sweet, especially since I only ran a 15.4 a few weeks ago with just my cat-back, so I bet I could get this thing flying pretty good. Thanks for all of your help guys, and I'll post my low numbers in a few weeks.
