Talking Summer mods?

Hey whats up guys? It's snowing so I've been cooped up inside and bored. I'm going to want to do about 2 grand of mods on my lt1 this summer. I want to do the lt4 kit, but that i heard is not worth the money. Hot cams? What are your opinions on that. I'm definately putting on some longtube headers, not going true duals (cops will pull me over constantly), maybe magnaflow cat back, a new MAF, I am looking into a rear mounted turbo. Is that any good? Anyone use one, couldnt find the brand STS through the search function.

sounds like you don't really know whatyou want to do.

What mods do you have already?

I suggest bolt ons then a camm swap for starters.

tell us a little about yur car...miles/tranny/ect.

Start by fixing any existing problems/opti/plugs and wires/fuel pump/ect.

My favorite parts for a stock car would include:

TIRES! TIRES! TIRES!-get some Nitto 555R or M/T ET Street Drag radials
GMMG chambered catback
Long tube Hooker, Jet Hot, or Pacesetter Headers
Off road Y pipe/cutout (ORY)
Lingenfelter Cold Air intake
PCMforless mail order tune
1.6 Roller Rockers
BMR/UMI point subframe connectors
and I'd ditch the EGR/AIR system (state laws/enforcement pending)

Honestly, that'd all be over $2000 probably but it'd be a very good start.

By the sounds of it, spend $2k on well thought out bolt-ons and you'll see huge improvement.

This looks like a great starting point for a stock car. Definitely have a well thought out plan first though. For example, if you're serious about a rear mount turbo then your not going to want to buy a catback (among other things, but that's just one example).

You forgot valve springs, if he does the 1.6rr. I'd wait on those for the cam swap anyway

this is just my .02 if you wanna go fast for cheap..pull the front and rear pumper take out the supports. get some fats and skinnys with good tires. headers and a good cai a tune deff wont hurt. if you want to build a turbo motor the correct way 2k is gonna get your not very far. crank and pistons maybe

Just remember to think out your options, pick a specific goal, do tons of research, and pick the right for your goals. Otherwise, you can waste a lot of money and time doing things twice.

Do stuff right the first time, and don't cut corners.

I heard a great quote recently:
"Fast, Reliable, Cheap-you can only pick two."

if i had 2 grand to spend, i'd do CAI, full exhaust, stall, gears, and a tune. that'd give you some good improvements. and you'd probably have some leftover too.

The car is a 94 firebird formula, 125k miles, automatic tranny with "Transmission Perform" button (which is rediculously nice).

I have a cold air intake, i don't know the brand it came with the car. As far as stalls go, how hard is it to put one in and what is a good brand? I don't wanna DESTROY fuel economy, but I'm not a tree hugger. I'm only 16 so, gas money is my only money lol. But this summer I'll get to work a lot and I'll have around 3 grand. I don't wanna put a **** load in the car. I was thinking a ram air intake system with a WS6 hood. and anyone know anything about the LT4??? I kinda wanna do that. Or at least what other heads would be able to handle the new mods. Thanks a lot for your input.

Wow, sounds like you have no idea whats going on. Judging by your first post to this post. Bolt-ons dude. Intake/Full exhaust for starters. I really wouldn't be thinking about an LT4 swap if thats what you're implying in this post.

Honestly, I think that would be more than 2K in parts unless he goes used. I agree though, after reading his other posts that this is the road I'd recommend.

The Thunder Racing performance package is a decent deal for $530. CAI, Magnaflow, and airfoil. My brother has that on his 1994 Z28 A4 along with Nittos and a 3.42 rear and went 13.5.

If the OP has the transmission performance button then he has 3.23 gears, so I'd move those farther down the list and get the full exhaust, CAI, stall, and drag radial. Should make for a high 12 second car in decent conditions.

Those are some good parts for the money...but have you checked around for different catback sounds? they all sound very different. What do you want yur car to sound like?

here's a couple of quick examples...
