What's up? It has been awhile since I posted. Just letting people know whats up with the GS4!<br><br>I just ordered the supercharger for my GS4, and have gone up on the rims. Right now, I have a new upgraded torque convertor, and a SRT intake system. The car sounds like a V8 suppose to sound like. I am on 17's now, and I spin out, and burn rubber at will. I am at 330hp now, and crushing cars on the regular! Also crushed a GS430, and he couldn't understand how! (My stock setup for the GS400 will beat a stock 430 anyway!)<br><br>Since I am going with the supercharger, I HAVE to go up to chrome 18's, (18x8.5 in the front, 18X10's in the back.) I will be at 450 hp, and doing sub 5 sec 0-60s. So any new corvettes, z28, ANY BMWs, I will crush with no problem. Will have to stick with having one of the fastest Lexus's on the east coast. The tuner that is doing my car has a GS4 with 1000hp! Oh well!<br><br>I will post pics soon!<br><br>Lee

I just bought a '98 GS400 and would like to beef it up a bit. Any ideas? Or better yet, how can I increase the performance? Thanks.

First thing I did was upgrade to 17" wheels. Then I would look into upgrading your torque convertor. That will take about .6 off of your 0-60 times. Maybe look into the Swift Racing Intake system. That will give you another 25-30 hp. Those two upgrades will have you smoking your tires everytime you turn off the VSC. I have yet to lose to a 4 door car since I put those two upgrades. (540i owners hate it!!!) <br><br>Check out <a href=http://www.swiftracing.com target=new>http://www.swiftracing.com</a> and <a href=http://www.clublexus.com target=new>http://www.clublexus.com</a> .<br><br>Hope that helps<br><br>Lee
