Do you have any suggestions as to what cheap and simple modifications i can do to a 2.8l to make it run better? Even stuff i can do myself whitout parts.

aside from the standard tune up, not that i can think of. the 2.8 isnt really a performance engine, just economic

I just though about it, would a turbo, or even a TWIN turbo considering all the space there is, work on this engine? I mean, costs less than a swap but takes the performance to a whole new level? Maybe? Sorry, im not a mechanical expert...

I wouldn't think it'd be worth it on that engine, i'd go more for looks if anything else..

And this car needs to get it's looks repaired, beleive me... O_O

Yea i'd have to go with Pedal on this one. Get The looks going first. I am doin the same thing to mine. Unless i sell it. If not its gettin A V8.

I've been shopping around and looking alot on the net as to what i could do, apart from a swap.
The thing is that the car has a welded frame, wich is solid but it makes the car a bad candidate for an expensive swap. Basically what i'm looking forward to is spending up to $1500 and lots of spare time on it to make it run nice and swell to beat the local hondas until i have money for a better car.

I've narrowed down my options, note that i'm on a tight budget. I probably will go with most of the following.
1. Free-Flowing Exhaust: Most likely what i'll do is do a 2.5in line with free-flowing cat and cherry bomb muffler.
2. The air-intake/hot wires/performance plugs boogie, all the bolt-ons i can think of.
3. Stroke the engine (http://www.engine-parts.com/GMV6/gm28stroker.html) to a 3.1. There's quite a lot of work to do, like pulling the engine, but a friend of mine is a mechanic that has all required tools.
4. Holley 3210 (http://www.holley.com/502-3.asp) throttle body. Heard it helps alot.
5. Cam and Rockers kit (http://www.engine-parts.com/GMV6/28camspecs.html). Again, complicated but perfectly doable.
6. Turbo city. I don't know if it's even been done before.

... Or is a 3.1/3.4?? swap really more easy than i though?

Turbo city. I don't know if it's even been done before.



i've seen a turbo 3.1 driving around, he's consistantly running low 13's in the quarter, but he's put some money into it too.

the motor wasnt made to handle boost. hell, if ur going to swap, why not put something bigger under there? go for broke

Is the turbo 3.1 in the 1990 Grand Prix really that rare? It'd be the perfect thing. I'd like to swap a small block, but idk... It's been done so much, and i can't afford the gas price. I don't want a drag car, just something nice and lean. Beleive me, i've been in an IROC-Z and i love that V8 rush, but that's gonna be for later.

Ill keep an eye on this topic as im currently looking to add performance to mine as well. Its actually in my shop and within a month i should be redoing it. Midnight Blue metallic. its gonna be soo siiiick:)
