It looks good...I dont know who did that kit, but that is pretty much what I have in mind for the 98+ GS300's. The intercooler aspect of it is pretty much taken care of already, as with the turbo set up, but like as I mentioned before, when the engine management (fuel / ignition maps) is correctly addressed ... a complete kit will be very feasible.

I want it now!!! I need it now!! Let's find out some more info on it!! HKSpower GS4, are you creating your own turbo setup for the 98+ GS300's? If so can you give me some details on what you have done? I really want to increase my power on my GS3 but I need some help.

Yes, I am planning on creating a turbo kit for the GS300. Similar to the XS kit for the IS and the GS kit they plan to make, the mechanical components is not the major issue, it is the detail of the fuel system. For the XS kit (a great performing kit) a custom return style fuel system must be created to allow for the increase in fuel delivery needed for forced induction via such components as an adjustable fuel pressure regulator. With the stock returnless system, the stock fuel pressure regulator is near the fuel tank and pump, which limits the traditional methods of increase fuel delivery.

What I want to do is try to utilize the stock returnless system (for ease for the masses) and simplfy the process of turbocharging the 2jzge VVT-i.
From experience with another returnless fuel system that has been successfully turbochaged, I want to duplicate the same results with the 2jzge by utilizing the same engine managment system. The next factor, assuming that the engine management works out well, is the limitation of the stock fuel injectors and the pump.

I hope this gives you a little insight with what I would like to achieve. Let me know if you have any other questions.

Have you started on any parts of the turbo yet? Could you give me some advise on how I can get started on modifying my GS300? I want a turbo so what could I do to maybe get started on collecting the parts that I would need. Please advise.

CoswoR'z is the first Japanese garage to come up with the bolt-on turbo kit for the 2JZ-GE Aristo S300. Maybe it's them. Reasonable price. I remembered something like 540,000 yen (roughly 4,500 USD). Capable of 300~600ps. wow.

Hey Aristov3o0,

How fast are you running with the Area 51 Stage 1 Supercharger? What's the cost?

Thanks in advanced.

Don't do that... I'm betting a turbo kit for the V8 within another year...

Bliu the GS4 engine can handle as much HP as the 2JZ

thats a nice kit i'd like that! i would REALLY like that kit! that intake manifold IMO is better than the V300 manifold too cause it lets the air flow real nice, dont you think?
