@6 psi boost, roughly 65 hp and 85 lbs of torque, but that depends on the condition of the motor, type of supercharger, and obviously, boost levels.

Ive already got an intake and exhaust, but is there anything else for this engine? I found an intake manifold for a non-turbo supra, but i cant find headers, throttle bodies, etc. any suggestions?

make sure the bolts are VERY tight.

Turbochargers are great for high-end power and a peaky torque curve due the the lag since the turbo needs to spool up. Because of that, the bigger the turbo, the longer the lag and the less torque you have off the line. However, the potential for overall performance and power are much higher than a supercharger due to the ability to boost 1 bar and much further beyond (1 bar = 14.5 psi). Superchargers (except for the vortex) are belt driven and work off the pulleys in your car. Since they are mechanical, they are limited by the size of the pulleys and the engine's baseline power. Because of this they are generally limited to 10psi and below in many import applications. However, since they are motor driven, the torque is instand and provides a long linear torque curve with great power off the line for very quick launches. The downside is the potential for higher boost pressure is bleak. Many people in the import world prefer turbocharging to supercharging due to the higher potential for power in a small package. Also, turbo lag can be counteracted by simply using a nitrous kit that triggers at wide open throttle.

A great combo is the Eibach pro-kit and a set of koni adjustables. A drop of about 1.5 and a decent ride to go with it! Its been working for me for the last 30k miles!

I blew out my factory tweeters in my 1998 GS300 and I needed to know which ones are compatible, Ive been having trouble locating a pair I can use. Thanks

Im looking for new rotors for my 98 GS300, and I just wanted to know the differences between the front and the rear brakes. Calipers, rotors, pads, etc. Thanks in advance for any help!

Would it be ok to use a 9005 blub in the foglights for a 98 GS300? I know it should be a 9006 blub, but what exactly are the differences?

For a budget, the Eibach pro kit springs with a set of koni shocks will be a well rounded package for the price.

I just got my lexus in Dec. of 2003, its a 1998 GS300 Well, my car got rear ended in a parking lot, and now i need to get a new bumper. Im thinking of just getting a new kit and putting it on instead of the OEM part. I would like to do it myself, but I am having a bit of trouble figuring out how to remove the front and rear bumpers. Does anybody know how to do this? http://photos.friendster.com/photos/07/10/...4321876258l.jpg 1998 GS300 InJen intake Greddy Evo exhaust Eibach pro kit Koni yellow shocks 18 in.

I was thinking about getting a header, but I would really like to get a new paintjob to make it black. Thanks in advance for any suggestions.
