sounds like a great Idea........ to bad you were not on the west coast i might give this a try.......

Thats why i say ill sponsor the first one i do, ill pay for shipping, About $1500 fully insured car hauler co. there and back from Cali. Ill post daily progress pics on here everystep of the way. Im very confident in this swap, this is cake compared to the 2jz i did, and i completed that swap from start to finish in 31 days. I have it all documented on video, and would do the same for this swap. Im looking to fully sponsor the guy who wants to try this, no money needed from you. Thanks!

 

then you need to learn how to drive bud. i can totally pimp slap full bolt on K's. and as far as that goes, the F20-2 responds to mods just as well as the K does, that been proven.

as far as the swap issue goes:

the SR is NOT a better motor than the F20. my bolt on F20 can put muscle a SR20 on 15psi. boost a F20 to 15psi and see what kinda power you make. your 2Jz car is neat but, really why? whats the point? why not boost the F20? there are 700rwhp s2k's. sure your not going to make 1000hp like the 2jz spits out, but what the **** can you do with a 1000hp s2k?

i just dont think the s2k is one of those "swap" cars. out a LS7 in a S14 and i'll pay 16k for that!

 

Toyota or Mopar USAC sprint car motor. 2.7 litre, 4-cylinder, 2-valve, NA, NASCAR heads, make 325 to 350 horses all day. The Mopar is actually a half a hemi. These are low tech, but the horsepower and torque while sticking to a 4-cylinder is amazing. In the S2k though, not sure I would trade my F20.

 

mother####er. I just wrote a great response and I ####n deleted it by hitting ctrl a and the space bar. Now you get a crappy version:

What are your goals? Street? Show? Road race? Drag race?

Performance/shock effect: stock LS7, no need to modify, reliable as any option, cheap to maintain, fuel efficient, durable, parts all over, tons of shops to help you. Scores a 95/100 on originality as well. Sure you could get a LS1 and mod it, but if there was an LS7 s2k next to yours where would the crowd be?

As dangerous and difficult to control as the low end torque of the LS7 is going to have, it's a LOT more manageable than a 600whp turbo ANYTHING is going to be in a s2k open chassis under 3k lbs.

13B would score a 96/100 originality and show everyone out there you aren't just a bitch with $$$. You have to understand mechanics to even dare go that route. It's low torque/solid hp production is a perfect match for the s2k and going single turbo and replacing the coolant/exhaust systems nets a reliable drivetrain, no matter what ANYONE says [relatively speaking]. 20B is a step further but you are starting to go a little 'too' far as many normal people won't know what you are refering to since it comes out of a luxery sedan only sold in Japan, as far as I know I could be off slightly. Not to mention parts are going to be a PITA unless you have an agent/contact in Japan.

For about 15 grand you could have a 340-360hp NA2 NSX engine, partially including the install, as no one will give you a definete cost on that job. That is if it can fit sideways, not sure it can. This would create the easiest to drive and fastest s2k on the race track, IMO.

K24/K20 is just dumb besides to be unique. Sure it can produce a little more, but don't prove people that honda guys are willing to blow 2 grand to swap their 1.6ltr for a 1.7ltr for 15hp and 8tq. Bolt-on K20's produce 200whp typically, up to 220whp with good cams and tuning. K24 bumps that up 10-20whp and 20wtq. There are exceptions, but there are also 300whp s2k engines. They are race engines on time vs miles, but what I'm saying is it's better, but not enough to justify near the trouble/expense.

Face it, if $$ completely wasn't an issue we'd have a zonda S not a honda S.

 

RSX 500lbs heavier than an s2k? I want to see that. Fairly heavily modded RSX's will run with or beat s2k's, s2k's make 190-200whp stock, modded rsx's make around 200whp stock, similar weight, RSX may have better aero's [s2k windshield is KILLER], similar gearing, and the RSX certainly has less drivetrain loss. Given what you said about your car, it may have 210whp on a good day. Based on what you said about the RSX which had more* mods, it probably produced similar numbers. Nothing magical there.

Horsepower is nothing without torque.. I don't mean to be one of those jackass physic professor want-to-be guys.. but that's a little missleading. The fastest cars in the world have a similar or worse hp->tq ratio than the s2k. HP is much, much more important in any racing condition than tq is, by definition basically. Every few months this is brought up in the clubrx-7 forums and the physics brains eat it alive. I could go on using examples of sportbikes etc. but won't bother.

k20 does rev to 8k, my friend conservatively has his set at 8650 on K-pro. Now if you are talking about the k24, obviously*** this is still not true. The BLOCK sets the limit NOT the head. 8k is the limit on those builds unless you go deep. I know 2jzs2000 already knows this if he's messed around enough to build a 2jz s2k himself.

 

The RSX-S weighs less than an S2000, not significantly, but Honda rates it at 2778 lbs (Link for Reference) versus the S2000's 2809 lbs (Link for Reference). Its not a huge difference, but I would say their weights are pretty much the same -- definitely not 500 lbs heavier.

With similar weights, I would imagine you can compare RSX-S 1/4 mile times with what an S2000 could run (ignoring aerodynamics here, which would have an impact).

Personally, I've seen VERY fast NA RSX-S's run at the track. I've seen a 14.0 run by an RSX-S with I/H/E and a good driver. Remember the RSX-S is FWD so its got more problems gettin outta the hole than an S2000 (assuming a good driver of course). Add Hondata, and some racing slicks to the RSX-S and I'd imagine you'd have a faster car than a stock S2000.

As far as responding to mods equally, the K20 definitely responds to simply bolt-on mods better than the F20. The F20C is basically a maxed out engine from the factory. With some major modifications it can make more power, but not too much with simple bolt ons. In terms of peak horsepower, you're lucky to get 5whp after adding I/H/E. The RSX-S stock makes about 170-175whp stock (no way they make 200whp stock -- the car is only rated at 200whp for the 2002-2004s, 210 whp for the 2005-2006 model -- 15% drivetrain loss would put you around 170whp). So to be making 200whp modded its pretty good.

In the end, an engine swap of a K-series into the S2000 isn't going to make a super-fast killer car, but I still think a K-series S2000 will be faster than the F20c/F22c. I personally think it'd be pretty cool to see, but I guess to each his own!

 

Maybe you missed the part when i said theres nothing wrong with the f20c, all i heard from you is a bunch of 15 year old talk , just trying something different man, not trying to prove the f20c is junk. Lets be a little more mature about this, just trying to get feedback from the s2k community before i swap another one. Id like to give you guys what you want to see. Oh, and why dont you come pimp smack my s2000?? ....yeah.

 

Thank you! I agree with everything your saying. I was really off on that weight difference huh? Wow, i didnt know that. Learn something new everyday! I agree with the f20c is allready tweeked out by honda right out of the factory. The k20 taking to bolt on's and k-pro, a definate proven good hp gains. I still want to proceed with this swap until i hear good reason not to, im not doing it to make big power, i did that with the 2jz, just simply want to see another s2000 swap. I think alot of s2000 owners would too.
