Except the engine would cost as much as the car.
Keep an eye on the vacuum lines to the wastegate. I was using a synapse that would melt the vacuum lines... I had to switch to a JGS that had proper fittings on it so I could run telfon/AN lines to it.
Boost is fun. This is my stock K24 at around 450whp... basically 10mph per second with roughly 70-80% throttle:

Bigger than what you're going with: GT35R w/ 1.06AR ... T4. On track, it does well... slower corners feels a little sluggish as it ramps up, but very controllable. I'm curious what a smaller AR would do to the response... I originally wanted a 800whp setup, but at 550whp, it's scary -- this setup will pull on a Radical SR8 / 911 turbos / ZR1s.
Boost is at 16psi, peak at 18psi.
The transmission is a quaife sequential, dog engagement. I know they make a box for the S2000 -- but you'd have to get the flat shift... it's the best thing ever.

At that power level, did the Quaife require an oil cooler, I thought they came with an oil pump? Would the Quaife have supported 800hp? I thought they are rated for 750hp; did you decide on the Quaife after you decided to stick at 550hp? Did you consider paddle shifters?
Ian, where did you fit the brake ducts with the oil cooler taking up one of the front openings?

Current build is darton sleeve block, 10:1 CR w/ CP pistons, manly rods, supertech valvetrain, and DC2.2 cams. The engine is sitting at 550whp at same hp -- didn't make much more power, I wanted the engine to be more reliable than powerful.
Quaife doesn't come with a pump, but does have provisions for it.

Paddle shifters add more weight and complexity -- both of which I do not want. Car weighs ~2350lbs, adding paddle shifters means you need another pump, associated hardware, etc, etc. Sure, it may only be 20-30lbs, but it adds up.
I got the quaife after I sheared a gear in the stock RSX-S gearbox. Kseries gearboxes are notoriously weak, very much like the AP1 diffs.
That's awesome!
