I've tried to point out a major problem with installing a K24 in a RWD application. I've seen both blocks up close and personal.

If you can't take the criticism maybe you should try other ways to recruit customers of your shop.

Given the cost of swapping in a K20/24 and adding all the bolt-ons, I don't think the swap is really worthwhile in terms of results. It seems like everyone agrees on the K20 numbers after bolt-ons: 200-210whp (probably less going through an S2000 tranmission).

Assuming roughly equal engine weights, and this really doesn't sound like much improvement over the STOCK F20/F22. for the time and money involved, you can probably make up that power difference with less headache sticking with the F20 and adding intake/exhaust and a tuned AEM.
Im starting to agree i guess, the k20 may not be the one to go with, i was thinking k24 bottom end /k20z1 head, high compression pistons, with the toda flywheel, toda cams/springs, Toda I.T.B's, and k-pro. This set up would be costly no doubt, but could be one B.M.F !! Torque is where im trying to go here guys, an N/A monster keeping it all Honda, that was the idea. But maybe ill kick around something else. Thanks for your valued opinions fella's

to the people who suggested the NSX motor, it can't be done as it spins the wrong way.

I also still think the F20C is better suited than the K. The K is able to make those great gains because it has something the S lacks, the programmable ECU. If you invest the time in tuning, I think you could match or beat what the K's put out.

You're starting with fully forged internals (which WILL be more reliable at high RPM over time) and probably THE best flowing head out there.

Again your mistaken man, im not trying to recruit customers, i have too many as it is. You only live once man, and im doing what i love to do. But i get bored of things very easily, and enjoy building stuff like this. Thanks for pointing these things out to me bro, really, i dont mean to come off as a know it all, sorry if i offended you, but from the looks of things im seeing certain things, engineering wise alot different than you. Remember, with enginuity, time and money, one could build almost anything. Your saying this cant be done is pure ignorence. This problem your pointing out to me is not a problem to me, i can take the critisism if deserved, its just hard to listen to some guy that knows nothing about me tell me what im capable of accomplishing with the skills ive spent my entire life learning. But thanks for your opinion, thats what i came here to get. Not customers. I have a website for that, and business is very good, allways has been.

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. 210whp from a K with the stock tranny is probably more like 195-200whp if put through the S2k's drivetrain.

I do like the SR20, and a properly built 13b would be a nice high revving, compact alternative as well. Except from what I saw on the 2JZ S2k vid, someone doesn't know how to build a rotary.
oh snap!

Exactly, that consensus on FWD whp and RWD whp means that both engines are probably very similar at the crankshaft... close enough to question the cost/benefit of doing the swap. Performance-wise, it seems marginal at best. A K-series swap in a technical exercise, not a practical performance upgrade. For what it's worth, it would still be neat to see.

As far as a 13B goes, I see that as a step down in many ways compared to the F20C/F22C. In a mild state of tune, it won't make as much power as the F series, yet have less reliability, more oil and fuel consumption, be dirty as hell, and fragile to boot.

If you go Renesis, then you are getting about the same level of power and torque, but with a smaller package. The difference isn't going to be much: the Renesis isn't going to save a lot of weight from the F20, which is fairly light. You'd still be giving up fuel economy, oil consumption, and probably some long-term reliability.

The wankel's benefits are space/power and smoothness. Compared to most engines, it offers V6 levels of power (but not torque) and smoothness in a smaller package. But then, so does the F20C/F22C.... and without the downsides of rotary power.

No, of course not. there are special engine mount brackets being designed to bolt from the side of the k20 block, to the f20c stock motor mounts. Common Guys, you all will have this completed before i do giving you all my secrets! Its my job man, its what i do. But seriosly, this is gonna be cake. These two engines side by side in the garage floor look identical next to eachother, other than the intake plenums look a little different, and the lump on the valve cover(the VTC Acuator) Do you guys ask your doctor what exact position his finger's gonna be when getting your prostate exam done? I havnt had one yet, but im just gonna let him do his job and ask no questions, unless of course i see both his hands on my shoulders when i feel the pressure!!
I havent finished reading this thread yet, but that was hilarious. ...

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.
