Anyone an expert in removing the traction control system in a first gen GS? I have the manual and have been able to locate most of the components, but I'm not sure it's worth ripping out. I did some searches over at supraforums and everyone their said that getting rid of TRAC destroys the tranny. I know some first gen GS3s didn't come with TRAC, and I thought the tranny's were the same. Any advice, thoughts would be greatly appreciated.

 

there is a tutorial on it at mkvii.com (mk something .com lol) IMHO its not worth doing. The reason they do this in turbo supras is when you have a big turbo and are pumping mad pressures into the engine the trac butterfly valve disturbs the airflow and removing it can make a substancial difference. In our na cars it does not do anything except come in handy when it is wet. I wouldn't remove it if I were you especially since i can't get traction for **** in the rain, with trac off in the lex when its wet my rear end will start to slide if i punch it even a 40mph. Won't be anything but extra work for you with no gain. I thought about doing this too a while back but like i said, alot of work and no gain unless you are going turbo.

 

I agree with Gomka, removing traction control is very troublesome and the return gains are not that great unless you turbo the car.

If there's anything I'd experiment with, it's the 2 inch diameter EGR tube stuck in the middle of the intake track just after the throttle body. If you open your throttle and look back, you'll see a brass tube that is in the middle of the airflow. I'm sure that has to restrict airflow, but it's necessary for the egr system. I thought about cutting it out but I believe it was made that way so it would distribute egr gasses evenly into the cylinders. Maybe a smaller diameter pipe could be used so it doesn't restrict so much airflow.

I know that in Supraforums people removed this pipe but they also disabled the egr system. And then to stop the computer from sending out error messages that created a jumper or something so the computer thinks the egr system is working. I'm sure this won't pass a smog check. This is why I think a smaller diameter pipe would be the better solution. If you look at the brass pipe you'll see a small hole where the exhaust is introduced into the intake air. To me this shows that very little exhaust gasses is sent into the intake, so maybe a smaller pipe would do the job equally as well.

Just a thought if you want to experiment, although I don't know how difficult it would be and how much you can gain from it.

 

Thanks for the great responses guys... excellent thoughts. I just have this mad bug to get this baby to move any way I can. Guess it's time to go stare under the hood for the afternoon.

I know what you mean man. After carefull thought I have found the cheapest way to get the lex going is to get a NN kit. (kinda like NX express kit). But NN stands for natural nitrous, all you need is a can of refried beans.
