I want to do a little moding on my 99 SE and i was wondering if u guys know any good mods for the L36, and im thinking about putting in a supercharger from an SSEi but i dont know if it would be worth it and i was hoping u guys could help

im looking at buying a rebuilt supercharger from GM heres the link: http://www.psesuperchargers.com/Product ... 8-2003.htm

You would need much more than just the supercharger. The heads would need to be changed, the lower intake manifold changed, accessory bracket changed...not to mention the fuel rail, the injectors, and running the new fuel lines as the L36 lines won't mate to the fuel rail.

On top of that, the PCM needs to be reflashed for an L67 tune, boost control wiring needs to be added, and the transmission beefed up with a heavy duty differential and matching passenger axle.

That's too much like work.

ya ive done some research and found out that a swap would be the best way to go so i think supercharging is gonna be to difficult, but does anybody no any good mods for the l36?

Plenty of good mods. Cheapest would be gutting your airbox. If you have not already done so, I would do the lower intake gaskets...replace those with aluminum-framed ones and there's a good chance that motor will last forever...or at least much longer than with the stock gaskets. While the lower intake manifold is off of the motor, either yourself or someone else could port match the intake. That single mod will make that engine respond well.

alright thanks and is intense racing any good?

Intense is very good. I've been running an Intense-flashed PCM for ~2 years now with nothing but good things to say about it. It definitely woke up the car. The transmission tweaks are the things you notice most about it. Being able to drop 2 gears by flooring it is nice. It's not the absolute best tuning option. It's good enough for the guy who wants to plug-and-play a tune. Overall, I'm very satisfied with their PCM.

Here's where you could go with your SE for ~$500: Tuneup, 180* thermostat (also required for Intense PCM), Intense PCM, polyurethane endlinks, gutting the airbox, Amsoil EaA air filter, ported LIM. That will give you a better-driving, better-handling car.

First, before you do anything, check the car for any mechanical issues, and get those taken care of. Also, if there's any rust, make sure it's not car-killing, or won't lead to structural issues after you've sunk money and time into the engine and suspension.

alright thanks heres what i think im gonna get; intense fenderwell intake, intense pcm, intense 180* thermostat, a ported LIM, 4" speakers for the front, and maybe subwoofers if i can find some cheap

You take 5.25" front speakers....the 4" just won't cut it for you.

are you sure? cuz crutchfield is saying 4"

Yes, your speakers should be 5.25"
It's easy enough to check before ordering though.

ok thanks guys

Definitely 5.25" for the front. If you have the tweeter grilles, you can get components with separate tweeters.

yes. 5.25" in the front. also, you should get components. they sound better, and i'm sure you could find the tweeter grills somewhere on this forum. that's what i did. now i have a nice set of Pioneer components in the front. go for it!

Let me put this very simply: Crutchfield is WRONG. They have been wrong before and are still wrong with this. That's all it is. I know they're a useful source of information on what fits in various cars. But they're just wrong on this.

i ordered the 5 1/4" and just put them in, the fit perfect just wanted to thank u guys for correcting me on the size

that's what this forum is for!

what kind did you get, out of curiousity?

Out of curiosity, have you done this yet?

If not, you better account for about 200 of your mod budget right there, and do that first. It'll give you the opportunity to port your LIM, which is the biggest flow restriction on the motor, and will enable all other mods to perform far better.

i got pioneers (very happy with them)

honestly i am yet to do anything to the engine and it could be some time before anything happens with it. i will definitly put the money into fixing that before anything gets done

i was looking around on intense and found gm uim and lim gaskets that would fit my l36 i was wondering if these would solve the problem
