I am interested in doing this. Currently i run a NOS setup 120 shot running through a HaltechECU which controls all the aspects of the engine.

really... sweet... i have a GS300 too and i wanna do a bunch of things to it... but not yet. I think there are a couple Turbo GS3's rolling around, but their not on this board for whatever reason, if you would be so kind as to e-mail me some detailed info and maybe pics on your GS3 haltac NOS setup it would be much appreciated, or post them here, thanks

Thats my car about 1 year ago august its 2000 gs 300
Bought it in August from the dealership started to modify it as soon as i got it. Got the greddy pe exhaust,Greddy front lip, Homemade intake out of aluminum,nos and haltech prepping for the turbo as soon as i figure out where i can mount things.

Should be using FMAx manifold t3/t4 63 trim turbo with custom downpipe mounted to air water intercooler to save space.

Haltech is a pretty respectable company in the engine/computer tuning field. I heard from somewhere that SRT's intake ECU was somehow developed in conjunction with Haltech or something. I could be totally wrong.

waiting for the turbo setup to get everytthing dialed in. the unit i got from CTC at it retails for 1045. Its is tuned based off laptop and some good ole dos software. you have full controlability of cam changeover points, fuel curve, timing curve. Still waiting to get my level 10 tc before the car goes under the knife in October.
