Hi All, so I finally took out the S2000 for a test drive this weekend and was very disapointed in the power the car makes. I really liked the way the car handles and the design. I currently have a turbo'd Miata and definetley don't want anything that much slower than my current car. So here is my question, how much HP can you make on the stock internals (I'm talking about safe reliable HP). Are there any good kits out on the market right now something that's complete, fits well and has proven itself. Will I need to replace the clutch, how much power will the rear end and transmission take before blowing up. I will probably end up going with stand alone ecu and wanted to hear from some of you guys that have installed turbo chargers on your cars about the costs, problems and any info you can relate.
Thanks in advance.
Mike

With stock internals, engine reliability will begin to become an issue above about 290-300 wheel HP, primarily due to the high compression ratio (11:1). Most FI engine failures seem to be a result of detonation. For more extreme motor builds (>300 rwhp), standalone engine management is therefore essential, and lower-compression pistons should be seriously considered.

The stock clutch is inadequate for forced induction and will need to be replaced. Other weak points in the powertrain seem to be the ring & pinion gear and rear half-shafts, though the diff gears themselves seem to be pretty strong. In any case, drop-clutch launches WILL break something, sooner rather than later, and even with a stock motor.
