Default 03 GS Na-T technical help please

ive tried searching of Na-t thread for gs300 but not specific to what im looking for. Greatly appreciated if you guys can give me some tips. I have 03 gs300 with about 90k on, i want to go turbo here are my priorities:
- maintain drivability ( i drive my car daily)
-270-280 hp to the wheel
- keep all the Gs functions

i went to the Na-t forum but i think their thread are more towards SC's, so i wasnt sure if those information would apply for what im looking for. Any setup recomendation? What parts would you use, like fuel manage system, type of turbo, basically what hardwares i would need. Any shop in Souther cali that has extensive experience with 2jz specifical with 2GS? Thanks again

Just out of curiosity, if you want 270 at the wheels, why not a GS4?

Default I will have to agree with Coco buy a Gs400 for that power level->

Or another option would be to supercharge your Gs300. If you really want to go turbo a standalone is a must to maintain reliable driveability. I am using the Tec3r for my engine management and it retained all my car functions. The only down part was the cost. Other options AEM, Haltec, Autronic. I will close by saying this 400rwhp is when the fun begins on a GS300.
Later, Jose

Too damn true! lol. On another note, you can get the GS running reliably with 440cc injectors + AEM FIC to around 300-350whp if you know how to tune it correctly. I've done it a couple of times now. Once you start exceeding 450-500hp range then a full standalone is the only option.

Another question is how often do you guys drive your car? Jeff you live in texas so lots of open road, here in So Cal, its not the case. This is my only mode of transportation for the time being. Can you link me on some more of your turbo write up Jeff? Its very informative, oh btw what front bumper is that on your car? it blends in perfect with the FMIC.
