I think an oil cooler POST turbo wouldn't be a bad idea if theres a nice way to set that up.
However I strongly disagree with everyone being against turbo cars on the track. I fully intend to make a track car out of mine. I've had turbo cars prelude,ZX TT in the past and never had issues with either on the track. I think the koyo radiator upgrade on it's own would be the end to any problems you MIGHT have had. The other good mod is a baffle for the oil. That's a concern more on track then AutoX though since AutoX doesn't have extended periods of high G corners in one direction. I in general am against turbo for AutoX since it is constant on off power applied, it exaggerates what a turbo car does worst. Not to say it can't be used correctly but it makes it MUCH more demanding to get the most out of the c ar. I wouldn't be surprised to see most drivers do better in auto-X by short shifting quite a bit in a turbo car.

1. Turbos run off of hot exhaust gases and will literally glow red hot during period of extended boosting. For example, here's a turbo Miata:

2. While this under hood heat is not normally an issue with cars designed for forced induction, I do believe this is the main problem with many turbo S2000's because the turbo is typically situated next to the main fuse box and a motor mount. The close proximity to both could harm our gel-filled stock motor mount and wiring harness.
In addition to the previously mentioned cooling modifications, I would consider relocating the fuse box to get the wiring away from the turbo. I know some guys wrap the motor mount in thermal insulation...that seems like an easy solution.
I would love to see a reliable turbo'd track S2000...I would love to enjoy the additional torque and wider power band of a lower boost turbo setup.
Cheers,

dont you think it would be a good idea to get a turbo kit with a better tuning solution and one which actually produces a smooth powerband without dips?
It might be smarter to go with an inlinepro kit and get it properly tuned with the proper sized turbo for what your trying to accoplish.

rev-hard ....mines water cooled GT30R... .lots are.
INFO
I jet-hot coated my snail and yes it helped out but only a little, but its noticiable.
Yes I had a battery begin to melt before I went with the PC680MJ which doesn't sit so far over. I also had the fuse box begin to melt but the easy solution there while i was in vegas was some aluminum foil. Now I simply don't worry cause the hotcoating on the turbo made enough of a difference.
If you run a log style cast manifold I would ceramic coat that as well as its even larger then the turbo and creates a ton of heat. Performance gain as well. Both hotside of turbo and the manifold will help the heat go to the turbo where it should. Slightly less spool time to be expected as well.

I am looking forward to seeing a reliable track-driven turbo S2000.

That is my goal with my upcoming turbo setting. I have ~30 track days and ~20 or so auto-x up to this point. I plan on doing everything I can to make my car reliable for 20 minutes of track driving with a 400hp turbo setup.

cool thank for all the suggestions and comments guys.
I'll think about moving the fuse box and battery as well as all pertinent electronics to the other side of the engine bay and aybe even vent my hood on that side.
Thanks
