Default Looking for a "doable" forced induction setup. Just starting out.

I have a 93 T/a that is stock except for the heads. I was considering going the forced induction route. After reading up a little I was thinking centrifugal supercharger. I want to stay away from turbos all together. Im looking to keep the car on the street for the time being. I am starting out now with a little over a grand to work with (This budget will of course increase over time). Where do I start? Looking for some advice or opinions.

Start with basic boltons. With a $1000 budget you can't even scratch the surface of a blower build.

What is done to the heads?

They were replaced with aluminum ones. Don't know much else besides that, they were on the car when I got it. With the $1000, I'm just looking at the beginning of the supporting mods.

If you are going supercharged, start with true duals. That'll pretty much eat up that $1k.

I was thinking about doing a set of headers/exhaust anyway. What other mods are needed for S/C?

fuel pump(s)
Injectors
built motor or at minimum forged pistons
probably some stiffer valvesprings
new rearend
built transmission

There's a ton more, but that's a quick off the top of my head basics.

Stock heads are aluminum. Need to know what you have before you can figure out what you need to buy.

there is a complete procharger d1sc kit for sale in the classifieds for $2800 last time i looked. a set of forged pistons, fuel pump and injectors, and a good dyno tune and you could easily drive it around reliably. now racing it would be a different story, but that is the bare minimum you would want

With that budget you could do a nice nitrous set up. A healthy bolt on LT1 with a 150 shot can be a mid 11 second car.

if you really plan on doing boost in the future you'll definitely need exhaust, i'd do valve springs since the stockers are so weak, dont necessarily worry about the intake if you're going FI in the future as you'll have to ditch it, maybe just get a good filter that you can re-use later. while ur doing the springs throw a set of 1.6's on. you'll need to get a built tranny if auto, you'll want a better rear end, everything adds up.

you'll need a lot bigger budget to go FI, especially supercharged. although i would never go supercharged, but that's just me

I'm a turbo guy personally but with such a low budget you will never get that S/C setup because you will need all of the supporting mods. You can do a nice Nitrous setup for cheaper and still make great power.

So what is the verdict on a ballpark figure for a midrange setup that is still reasonable for the street, yet produces a decent amount of power? Can everything be done for around the 5k range?

Just the engine and fuel maybe for a supercharger you'll want forged pistons, valve springs, machine work, and a keyed crank hub at least. Turbo same but you can skip the keyed hub. You'll need big injectors and a dual pump or external setup too.

Not the bolt ons ($2k ish), rear end ($2k ish), supercharger system ($3k-$6k, depending on used, build yourself or whole kit etc).

It will only last about 11 seconds also.

A healthy stock LT1 can spray a 150 shot all day assuming it was installed correctly.

Whole new top end, forged pistons and rods, built tranny and rear end, and full bolt ons.. Get all that done and a supercharger will work like a charm

Plenty of cars have blown up using nitrous and I've seen what it does to other parts as well. Clutches that look like they've been burned etc :p

Based on what you guys are telling me, I might stick with some basic bolt ons for now. Anyone have suggestions on LT headers + exhaust?

if you can swing it, go stainless, and as big as you can afford, so you have room to grow. yeah it's possible you'll lose a tiny bit of bottom end but once you get a cam, heads, intake, FI like you want, you'll be glad you went big the first time
