Hey everyone. I was just wondering if anyone has ever swapped the K20A ITR motor from the DC5 into a DC2 ITR. I know it has been done on other Integras, but I'd like to know if anyone has ever done it with an R. The next project I have planned for my car, after getting the suspension in, is a K20A swap. I've contacted Hybrid Racing about their products, and everything looks promising. I should be ready to go with everything by early summer. I just thought I'd ask to see if anyone's done it before (and yes I searched).

 

i call dibs on your old motor if your giving it away

 

First $4500 gets it. But I need the payment about 3 weeks in advance.

unless its in writing and local, no one will do that

 

I don't know of any specific examples, but I'm sure it can be done just as easily as it can with any other DC2/DC4 or EG.

But why? Why not spend the money on rebuilding the B-series you've already got?

 

k20 is the way to go.. but i was more impressed with the following:

this one has itr engine, and its RWD Del Sol.

if you don't plan to build your setup (like boost and stuff), go with k20a swap. for n/a with boltons it gives more hp than b series. i should mention that if you wait few years, it will get much cheaper..

 

i thought the top fuel rwd del sol was a b20 turbo?

 

If you have the money I say go for it. I love the B18C5, but the K20 from a performance potential standpoint far and away better. People are making insane power NA with minor modifications and I believe a few are getting close to 280-300whp on pump gas with more in depth builds. It is also lighter and comes with an extra gear which never hurts.

 

i don't know (this is what i got from that thread, as far as turbo, well.. its turned the other way).. whatever engine is in there.. its still cool as ****.. i wonder if this would work in integra.

 

doesnt it put alot of weight on the right side of the car? atleast the mounts ive seen has. this seems like it will throw you off a bit in rr and auto x'ing.

 

That might actually help cancel out the leftward weight bias caused by having someone in the driver's seat.

 

Special Projects is doing it for the upcoming WCHC season.. The link below is to their announcement in the RR/AX forum..

didnt even think about that, but about those rhd guys? yikes

 

I know you want your car to be distinctive...but the B18C5 motor is the best Honda ever produced behind the F20C or maybe the K20. The money spent can be spent to make your car much better in other areas.

"Wow, you are the only DC2R with a K20." Enjoy those comments because they won't last long.

 

if you just want to be the "wow your the only one with a k20 in a DC2R" guy, then its sad really.

 

The c5 is a great motor, but as with anything in this world, evolution owns. The K20 is a product of 15 years of tuning, tweaking and most important, improving the B series. Like mentioned earlier, the engine is far more capable of producing power with the same modifications as the B18C5, and this is just the begining. I know as R owners, no one wants to see their beloved race engineered engine take a second to any other motor out there, but it's time.

Good luck with the K swap.

 

On paper, yes the K20A is a superior engine. It has many features I wish had been incorporated into the B-series design, such as roller rockers, square bore and stroke dimensions, a better-flowing head and, of course, 200 cc more displacement.

However, in practice I am disappointed with the K-series. The motor is not nearly as responsive as the B-series, a problem attributed to a combination of its chain-driven camshafts and the VTC programming. The engine feels as if it has an 80 lb. flywheel, IMO. And while it does have the potential to make lots of power, it doesn't feel as powerful as it's supposed to be.

But regardless of what I think of the K-series, the real question here is practicality. Is it really worth it to replace a B18C5 and deal with the hassle of making two things that were never meant to be combined work together, or would that time, money and effort be better spent on making improvments to the existing motor?

 

"Is it really worth it to replace a B18C5 and deal with the hassle of making two things that were never meant to be combined work together, or would that time, money and effort be better spent on making improvments to the existing motor? "

Well, look at it this way. Long ago many people looked at the ls/vtec setup as a timebomb waiting to go off. At the time, same logic said it was never meant to work together and those setups would never last. Fast foward to today and now look how reliable not to menton powerful that setup has become.

As far as the k20 is concerned, why not? Think about it. How much money will a well built b-series capable of 230-240ish whp run you? Now be honest with your estimate. Ask any well known engine builder what the FINAL price tag on that engine will be and your well over $8k. Don't laugh yet. Remember, to get those kinda numbers and still maintain some reliability a lot more is envolved than just parts. Machine work, porting, quality header, sleeving, you get the point....

Now, contrast that to purchasing a swap, mounting kit, I/H/E, and hondata reflash. If your starting with a DC5R swap then your talking same numbers but with 100k + mile reliabilty, 6 speeds, Lsd, a motor/tranny combo that weighs less than a b-series. Not to mention the k20 to EG/DC mounting kits i've seen have better geometry/location than the b-series. Motor/trans sit farther back now.

Now that i think about it, TODA has an engine kit that bumps those numbers 20 whp. So they say.

Not trying to convert anyone but for myself the choice would be obvious.

 

The question I posed was a rhetorical one. It can be answered only by Kendall, since it is his car and he will be the one spending the money on it. I mean to imply no answer of my own.

When I say, "not meant to work together" I don't mean, "Honda didn't do it that way and neither should you." What I'm pointing out is that the fact that the K-series was not designed for the DC2 chassis means extra work for the conversion. Not just a mounting kit, but things like wiring and emissions classification need to be considered. There are potential headaches waiting here, and these are things I would give a lot of thought to when contemplating such a conversion. This doesn't mean I don't think he should do it.

 

Oh.....i understand. Hope i didn't come across as some know it all.

Check out this thread:https://honda-tech.com/zerothread?id=611225

It addressess some of your concerns and gives a somewhat detailed account of what is envolved with the swap into an EK chassis bybrain g of Hasport. In an IM, he stated the same swap into an EG/DC would be easier and cheaper as well as have better geometry.

Some issues with emissions legality but then again most fully built setups are no where near emissions legal. peace.

 

if you're going that route might as well go with a K24 block and a K20 head set up

Exactly, potential. In terms of development time, the K is still in it's infancy.

Indeed CRVTEC the sequel!!

 

This is exactly what I'm shooting for. I'd like a good reliable all motor setup with somewhere in the neighborhood of around 250 horses at the wheels without the insane cost of a good B series build up. Reliability is the key word here, and due to the fact that I do a lot of highway driving, the six speed will certainly be welcome.

Yes, it should center the weight better in the car and allow for me to better tune my suspension to end up with a better handling car.

I've spent the past few months researching the K series engines and they have far more potential than the B18C5 does. I don't feel like I need to put a lot of money into improving my car in other ways as I already have removed about 250 pounds of weight and have purchased one of the best suspension setups available. There is always room for improvement over the stock braking system, I was looking into the 2004 TL brake swap but it requires moving up to 17 inch wheels, something I won't do.

Given my goals, I think that it's worth it. I'd be dumping somewhere in the neighborhood of $10,000 to get my B series the way I want it, and it wouldn't really be drivable on the street, and I'd need race gas. The K20A is looking to be a more practical approach toward meeting my specific goals while keeping it very streetable.

This is exactly how I view the situation.

I don't plan on emissions legality. Where I live, it's not necessary.

Thought about it, but I'm really looking to get one thing done at a time. I like the K24 idea, but it's really overkill for what I'm trying to accomplish and at this point would cost too much.

If I'm not mistaken the K24 and K20 already have the same head, well at least the TSX K24 at least. Someone correct me if I'm wrong. The main problem is the large stroke of the K24, revving really high would be a problem, but people are already destroking them to 2.3 liters so that isn't an issue as much anymore.

If people are making 240whp NOW without touching internals just imagine what the future will hold for the K series.

&lt; thinks 300whp pump gas all motor street cars are in the near future.
