-What I have done-
1994 Camaro Z28 V-8 5.7L
-Dual 3` Magnaflow Exhaust
-4L60E 2pc Case High Performance Race Transmission
-SLP Cold Air Induction w/ 2 K&N Air Filters
-MSD Cap/rotor
-MSD Blaster Coil
-MSD 8.5mm Super conductor wires
-Bosch IR Fusion Plugs
-TB Bypass
-Whatever odds and ends done to the car before I bought it.


-What is comming next-
-58mm Throttle body
-Stage 2 Jet Chip
-JET Powr-Flo Mass Air Sensor


What do you think about the parts that I will be installing this month? I dont want to get into the motor like cams and things, because it being winter, and I work 12 Hr days. But basic bolt ons? What about the "Big 3"?
How much would the Chip and the upgraded MAF / the throttle body give me? (i know i prolly wont need the throttle body upgrade...but why not? lol

run ac delco platinum plugs.

scratch the 58mm tb, whatever a "jet chip" is, and the maf. the last two are wastes of money and you, in no way, need a 58mm throttle body.... you will actually HURT your performance by putting that on your car is it sits now.

Use your money and get a nice set of headers and then a tune.

reamo04

agreed.
Buy some longtube headers.
If you have extra $$ sitting around, throw in some gears (3.73 since its an automatic), and a nice like 3200 yank stall converter

Then get a mail order tune, and your good to go

I was looking at the gears. Will this kill my MPG? (not that I get much as it is). I have 20` Rims installed aswell.

reamo04

those 20s are KILLING performance. I forget what the real number is, but its osmething like 1lb of rotating mass is approx. 6-7 lbs of stationary mass.
Gears will not really bother your gas mileage much, your just revving a little higher, not much. ive heard of people not even having gas mileage affected going from 3.23's to 3.73s

Im really not too keen on what these do tho. Will this increase acceleration?

What kind of Headers would you buy? I like the deep sounding too, I hate that high pitched crap.

My Red 93Z-28

Longtubes will give you a deep sound with all else being equal. I'm not sure about the high-pitched sound you are talking about.

Yes higher gear ratios will increase acceleration.

Ricers

My Red 93Z-28

That has to do with them only having 4 cylinders compared to 8

I know, it sounded good though. Im currently looking at either hooker headers, or PaceSetter headers. Iv NO idea how hard these are to install though, n how much of an increase in performace would i expect?

My Red 93Z-28

They can be quite a pain to install. I think on LT1's the gain is about 20 RWHP after you tune for it. It could be more or less I can't quite remember.

Agreed..... the 58mm TB ($300-400), JET chip ($320) and the JET MAF ($390) are a waste of money. No way you need a 58mm TB with your level of mods, you could get a good custom tune and gain real HP for less than 1/2 of what the JET chip costs, and there is no reason at all to change your stock MAF.

You need to work on the exhaust, as mentioned. Just out of curiosity, how did you run 3" duals, when you don't have headers? Or do you mean you have dual 3" exhaust tips?

In order to determine what mods would benefit you most, you might want to explain what your goals are. Do you street race, take it to the drag strip, want to Auto-X? With the mention of 20" wheels, it would seem you are more interested in building a show car than a high performance setup. Any engine and drivetrain mods need to be accompanied by suspension work, to put the power to the ground effectively, and what that takes is determeined largely by how you plan to use the car.... take one suspension to drive 1/4-mile in a straight line, another to allow the car to corner well.

From what I remember, theres a huge tube out of the stock headers, then the cat, then the same sized huge tubes go to a giant box thing and goes to two 3` tips. (sorry i dont know the correct termanloigy for them, im just getting into things like this)

My Red 93Z-28

Huge pipe - I'm guessing y-pipe, it's called a y-pipe because it makes a y to connect the header primaries into one pipe.

Huge tubes after the cat - exhaust pipes after the catalytic converter

Giant box thing - that would be your muffler, single inlet, DUAL outlet...not really dual exhaust.

Dual exhaust would be if the header primaries came down and instead of a y-pipe there was an x or H-pipe (again they have that name because they look like an x and H) then the two pipes go down to two mufflers, one on each pipe.
