go with custom supercharger kit. It will be fast enough with the low boost.

 

this is a motor swap in a IS, if you do this to our car you have to change the transmission, everylight in the dash will be on, the ecu will not match up to the car. It would no longer be a luxury sedan, It would be ridiculous though!!!

 

go through that thread. the ONLY warning light is "check VSC".
engine and 4 speed tranny swapped. even the paddle shift and gear indicator on the dash works.

this is just an example of what can be done when someone has the resources.

 

yeah it would be cool to have a chip for our car. those 335i's have one...

 

There is a larger aftermarket following for BMW rather than Lexus... Keep in mind that you dont "chip" a 335, you flash the ecu and for a good solution for a 335, it will run you around 2k. Any added boost in a 335 will require an oil cooler...

 

Hey just curious, lexus offers "F-Sport equipment" for the 3GS here: http://www.lexus.com/models/GS/f-sport/overview_GS.html
Are their F-sport products better than HKS? for example, HKS Hi-Power Exhaust vs F-Sport Exhaust?

 

It would be cheaper for you to sell your GS300 and get a GS450H or GS460 thats more then +100 horses!!!!!!!!!!!!!!!!!!!!!!

 

that is250 is siiiiiiiick.. and it would be crazy to see a gs350 with a 2jz-gte. wow, its still amazing how ahead of its time that engine was. were still using an engine from like 93' trying to get it in our 2010's lol.

do you think this actually works? is it worth trying it out and blowing your engine.lol. idk. seems kind of cheap to promise up to 60 h.p. i can imagine a gs at 360 h.p to be a rocket. i know i love the speed on my gs.

 

Total BS......

 

Toms Racing makes a turbo kit for our car for a discounted price of 15k lol!! You of course have to send out the factory ecu to be re flashed and they of course are not responsible for the lose of factory information. For this kind of effort I can buy a 2nd gen gs drop a 2jzgte with a single turbo conversion, jdm trans, aem computer, intercooler, airrunner and some seriously aggressive 3 piece wheels, I must now go clean myself off!!

 

It's total BS once someone actually tries it!

 

Come on someone do it for the team!!!!!!!!!

 

OK I will take the bait! I am buying it today!

If it works, you guys owe me big time!
