Oh yeah what otehr mods can i do.I dont want to dump the motor thats in it.Its in great shape with only 56k miles on it.Some old guy owned it before me.Suggestions please.

i don't think brackets will do the trick for ya. basically you need to swap in a GT engine to get any kind of turbo. there are many parts on our GL's that just wouldn't be strong enough to withstand the power.

you need to switch almost everything from a GT over, including...

engine (stronger internals and lower compression)
GT axles and a bigger spindle to support the axles
GT ECU
GT wiring harness
GT tranny
and a few other misc parts...

basically it cost alomst the same to turbo a GL as it would to just sell the GL and buy a GT. but you can still get some pretty good performace out of a GL with the proper mods.

To just add on a turbo that isn't meant for our car would be several thousand dollars. However, that's just to be able to run 4-6 p.s.i. (the amount safe on our stock internals) which isn't a lot. If you wanted to run 15 psi or something worth while, you'd need to rebuild the engine with new pistons and what not. If you want to keep your engine stock, go with a supercharger set up. They would cost about the same to do, maybe less and you'd get more performance gains from it.

Well, if it is a genuine WRX turbo, it can be done for $1200, plus a new tranny, clutch, axles, andd hubs.
The GL motor is stronger than some people think, although I don't recommend running 15 psi or anything like that.
True is it weaker than the GT, but it does have the same crank, and decent rods. The pistons are the same type of casting as in a Kia sportage, and they can take to boost pretty well.
If you really are looking at the true WRX turbo, 4-6 psi with the higher compression will make you feel almost NO turbo lag, and pretty good horsepower numbers. BUT, everything behind the engine won't hold up to it very good, so you will need to upgrade the drivetrain.
Also, the coputer will get confused, the injectors are too small, and you don't have intercooler piping, or an intercooler.
The GT's also have a oil cooler that you might want to look into, I don't know for sure if the GL's have them or not, but I've heard that they don't.
If you do just hook it up it will go BOOM!! So you will need to do something about the computer.

I can see this thing done for about 3000-3500 bucks, though, and it would be a real surprise to anyone pulling along side you. In fact the turbo will come on so quick, that they would probably assume you still N/A, too.
