Has anyone ever converted a N/A 3.4 in a 01 996 c2 into a turbo, is there a kit or a shop on the east coast that has done this?? I know about the supercharger kits available but I can't seem to find a turbo kit. Yes I know it would be wiser to sell C2 and get the turbo, yes they are cheeper now but I do not want to sell my car for any reason, so that is not an option and I can not have two p cars so that is not an option. Just curious at this point if this is an option or not and what the cost factor would be, Thanks in advance for your anticipated assistance with this. Yes I do track days and autox on a regular basis take direction from execelent instructors with PCA and seat time is a priority for me in my quest to become one with the car but I'm still curious if there is a turbo conversion kit or mod for this engine/vehicle set up. NOS is not an option for me.

I think TPC, is going to make one also.

Here is something to consider...while turbo "kits" probably can be fitted, you also have to consider transmission, brakes, suspension, numerous other internals, even axles as the torque can be significantly greater with a turbo...unless you have an unlimited budget to fix things as they break.

In order to get the full benefit of a turbo, assuming intercooling included, your engine must first be detuned, static compression ratio lowered to something in the range of 8:1. That, basically, would result in the car not being very satisfactory for use as a daily driver. Same is true for SuperCharging.

A more satisfactory forced induction solution could be had via the use an intercooled SC(***) and Toyota's new e/VVT-i system. But that would require some really serious engineering design and mechanical engine retrofit work. To summarize, the engine, DFI assumption, could run in standard Otto mode, 15:1 compression ratio, for light throttle/engine loading. Atkinson cycle, 12:1 CR, for moderate throttle/engine loading, and then Miller Cycle, 9-10:1 when Boost is required/used.

*** TurboCharging cannot be an effective solution with an Atkinson or Miller cycle engine. No "waste" gas to spin the turbo.

I've only seen supercharger kits. And despite the impression that you've read other posts here with the usual caveats about modifying your stock motor, this bears repeating: If you want more power, your best option is to buy more car. Sorry, it can't be avoided. :D If you stick with NA cars, Mk2 996s and early 997s are getting cheaper by the day and a powerkit or S motor will give you a substantial gain over your 3.4.

What about pricing a used Turbo drivetrain? I imagine this would be $$$$, but if changing your car is not an option it might be cheaper than building a turbo kit from scratch. I'm not sure if the stock 996 mk1 transmission is compatible with the split-case turbo engine, so you may have to look for a GT3 tranny to get a 2wd replacement.
