More Power & Fun w/ K24 From Prototype Racing
I've recently been in touch with Joe from Prototype Racing. He does primarily work on the Lotus Elise/Exige in swapping out the stock Rover and 2zz motors and putting a K20 or K24 application in there.
His first comment was on the Comptech S/C. According to him the amount of engineering Comptech puts into their street applications is not at the level of their race applications. So he in turn works on improving the quality of their S/C manifold. He said they just completed one for the K20A.
How feasible and practical is that application on the TSX? I would imagine that this setup with any forced induction would bring out some pretty good results. Anyway to the video I got.
The difference that engine makes between a stock Lotus and a Honda Powered Lotus is amazing... From what I recall the stock Exige has a 0-60 of 4.7, 0-100 of 12.3 and a 1/4 time of 13 flat. His car is pushing more than 100whp more than the stock Exige (and it is also lighter)
K23 Lotus vs Stock Lotus
He said that since his dash was out he was most likely short shifting his car at around 7,000-7,500 RPM so one can only imagine how fast that car is.

The TSX engine-trans will require a completely new set of engine mounts unless a K20A trans is used, then it's just one that needs to be changed.

Are you sure the stock Lotus wasn't standing still?

Well, that's the older exige that had the Rover engine, hence the 147whp. The new one is equipped w/the 2zz-ge engine and with the $$ spent to swap and do all that work, it really isn't worth it unless your dead set on staying N/A. Otherwise, the Forcefed or Hass Turbo kits are all that you'll ever need.
As for the K24, it already makes incredible power with forced induction or n/a. There's a guy in a EG hatch here that runs a Turbo K24 with stock motor and runs close to 500 whp. I wonder, if a turbo kit were to be produced for the TSX, wouldn't an Emanage Ultimate be enough to get it running correctly as long as the tune is good. It's compatible with DBW and I know of many people that run them for forced induction applications. The Elise guys don't have a Standalone EMS available and use the Emanage to tune their turbos.

He said that the forcefed turbo kit on the 2zz is not very stable. And though they install it they've had two motors blow already, and along with that the longevity of the setup will not last more than 20k miles without problems.
Joe also mentioned that after the K20A2 or K23A swap a Jackson Racing SC can be added and with 9psi of boost you can safely up your car to well over 300whp. All of this can be done for under 10k... now to a lot of people that would be a lot of money. However keep in mind that the Forcefed Kit is over 7k without installation, this is a Elise/Exige a afforable supercar, and for the performance you'll be getting (sub 3.5 0-60 and low 12 or high 11 1/4 times along with excellent cornering ability and a fast solemn time than an enzo... ~40-60K (used-new w/parts and install) on a car like this is an amazing buy!
Once I get the money after a year, this is hopefully what I'll purchase

There is not "K23" in production. It's a 2.3L K24A that was destroked in order to achieve a higher rev limit, 9,500 to be exact

That thing is just ridiculous. Awesome video man! 
There is someone on Clubrsx documenting their RSX rebuild. They are putting a K24 in a RSX with a Comptech Supercharger that has been modified by Joe McCarthy from Prototype racing. This is probably the modified SC kit that he was talking about. He going to be running 14 psi of boost along with NOS
Take a look in the Forced Induction - Supercharger section if you're interested. Let me know if you need a link.

Yeah, Joe was telling me about the improvement he made recently on the K20A2 SC manifold, maybe he'll do that for the K24A as well

Any more than 350-400 whp on one of these cars I feel is not going to be easy to control in such a lightweight car and could possibly affect it's performance capabilities.

Yeah that's the Forcefed Elise. I believe for this kit they bump up the displacement in the 2zz engine along with a bigger turbo. This car seems pretty freaking hard to control, even by this driver.

I believe forcefed just sleeved the block and lowered the compression, added a bigger turbo and upped the boost on their 400 Race Elise. As you can see, this amount of power can be had with the 2zz and it does seem to be too much for this chassis. Both Honda and Toyota powerplants can suit any needs for the Elise/Exige but I just don't think the swap is worth it unless you want to keep the car N/A in which the K-series motors will outperform the 2zz without a doubt.

And of course you'll still be FWD.
The CTSC might not be tuned for optimum performance, but neither are our cars when we buy them from the dealer. This is done for a reason. Tighter tuning means less reliability and more maintenance. Not a lot of TSX drivers with the CTSC are probably likely to agree to making these sacrifices, so Comptech sacrifices some power for better reliability and lower maintenance. Honda does the same thing with the factory ECU programming. When you get a Hondata reflash, you're eating a little bit into that margin of safety Honda allows for (bad fuel, poor maintenance) which results in a little bit more power.

there's always a solution for engine management if you have enough money... Motec M400 optioned up with drive by wire, stability assist and variable camshaft timing, about 4-4.5k worth, then add 2-2.5k (all in australian dollors) for tuning and you should having something...
