Thats what i was thinking, but i couldn't find a website taht offered them so i guess youd have to go through a dealer.

Yup. Be seated when they quote you too. I'd like to know just for the record though?

Yeah, this isn't anything I'm going to do anytime soon. Unless I win the lottery, or make-believe money is considered legal.

96, iL. Has the poo-poo stereo, but otherwise I like it a lot better than the newer ones with the lcd display in the dash. I took a picture a month or so ago like the one you had for a while with the two next to each other, just never got around to photoshoping it to make fun of yours. (it also wasn't very good of a picture, partially because our garage is filled with crap)

The bmw is eggplant purple, and has the stock wheels chromed. Tis quite good looking when clean.

Yea, let's get a $3,500 turbo and stuff it into a $3,500 car that it's the wrong size for anyway. That's a great idea.

Turbo-supercharging would be a fun project - something I've batted around as an idea. If you like low-end grunt you can either (1) get a Corvette, (2) upgrade to a 3.0L engine in your 944, (3) develop a good TT setup, (4) get a Callaway setup ( ), (5) change your gearing. There's more than one way to skin a cat, so to speak. . .

Thats not not really the truth.

You do know that you can overcome the loss of a supercharger by running a larger unit @ more PSI compared to running a smaller turbo @ less psi. Sure the supercharger has more loss but it still will produce more power.

Actually there was a VNT turbo production car made in the early 90's. It was the Dodge Daytona Iroc (225hp, 4cyl, turboIII). Very few were made and the engine looked very simmilar to the newer SRT4, except the SRTs use regular turbos.

All the 99-up VW TDIs have a VNT turbo. My DD is one and it gives boost at very low rpms and keeps it all the way till redline.

All I said was i couldn't think of any off the shelf variable vane turbos. Those were limitied production cars and the tdi is a diesel so i don't get what your trying to argue.

Anyways if you ordered a variable vane turbo as someone already said it would be teh wrong size, but more importantly how are you gonna control the vanes?

I have to admit that I would be happy with less top end, and more everywhere else with a quicker throttle response. Cat bypass and flow work would be the middle ground, with no loss of top end. It has also been said that the right gear ratios can give an equivalent performance increase of 50 HP.

What is the weight difference between an LT1 and a turbo motor anyway ? Since we are bored and all ...
