I trust this guys ability, that it will work if he can shoehorn a supra engine into the car and make it work. I think a k20 is a good idea, its not a power house like the supra engine, but the torque and nice redline will be interesting to see. When he does this swap I'd really like to see a race between a reg f20c...Our power band lacks so badly in torque that you never know, this might work out alot better then people think, and i't won't mess with the 50/50 weight distribution due to it being the same weight. I say try it out.

A mildly tuned 13B-REW will put down a lot more power than a stock S2k. Sorry for not specifying the turbo engine. It would be a slight step down in reliability if not built right or if the engine is still all original. I would go all out and buy ceramic seals and a mid-level port job if I ever have to take my 13BT apart. Ceramic seals negate the issue of breaking apex seals(unless you have a HORRIBLE tune) and any other issues would be a result of inadequate cooling. It's a picky engine, but performance-wise it would be great in every way. That being said, I would hold onto the F20 and not do a hack job just in case I wanted/needed to switch back.
+1 for versionJDM being the tester.

Also, the numbers that the K puts down can't be directly compared for a swap because the more compact FWD drivetrain saps less power.
Based on the dynos I've seen it looks like:
average dyno for 02-04 RSX-S rated at 200hp appear to be 165whp = ~17% loss
average dyno for 05 RSX-S rated at 210hp appear to be 175whp = ~17% loss
We all know dynos for our car are all over the place...have seen stock dynos as low as 185 and as high as 215. Call it 200whp average. Gives loss of ~17%.

I have heard this argument before and went looking for dyno plots to prove it...wasn't able to find any...in fact found that the drive train loss seems pretty similar at around 17%.

I still think the best bang for the buck is the original start of the thread, the SR20DET.
Fabulous aftermarket support, an easy unstressed 400 hp, a clear power path that works, and for those obsessed with torque, it has a lot more torque than the FC 20.
Just because another engine is a Honda doesn't make it a good choice.
