H22a4 to K20z1 swap - Honda Prelude Forum

Mrgarrison · 12-01-2009, 10:32 AM

i have been looking online for something to do to my 98 base lude which is getting ready to hit 200k after seeing that i could get a k20 for around 5 k it got me thinking, how much work would it be to do a swap? things to keep in mind , the exhaust and intake ports are swapt ( exhaust in the back, intake in the front, ) timing chain instead of a belt, less oil burnage, more power ( if i can get my hands on a Type R (which i prolly cant lol)) 6 speed tranny and LSD ( again in the type R) any ideas, thoughts, concerns, attaboys would be grealy apprectiated

I think it would be ****ing nasty! lol

I'll let you have a crack at my girlfriend if you do it.

That's how confident I am in this idea not going anywhere.

Didn't someone swat a k20 in a 5th gen a few years back then totalled it?

Regardless, I don't see much benefit from all the $$$, blood, sweat, and tears that would go into this project. Just rebuild the H22 of order one from Hmotorsonline for $1500ish

Yeah man, that's a lot of work, if you want a K-series engine so bad, get an RSX.

I think swapping the K20 into a Prelude is sort of wasteful, because I know people do it just for looks, rather than actual gains in performance. What a waste of time and money just to look cool, or different.

fatiye--Yeah, it was done a few years ago, and the guy did total it, I think back in '07. Here ya go: (original link I posted had no pics.......) This is BEFORE it died, apparently: K-series Prelude - Honda-Tech

Ha you should do it. Easily a $7000 project for roughly 20 - 30 hp. Attaboy lol

do it for this ^^ lol

You can actually make power with a k20 so that's a good benefit. If you were gonna build the engine for the swap it'd be a nice upgrade.

Realistically it'd cost so much you probably would just be better off with an rsx.

Tee-Dot · 12-01-2009, 09:50 PM

The good thing about leaving the K20 in the RSX is that you get the rest of the car, too.

Mrgarrison · 12-01-2009, 10:15 PM

yea but i can see the insurace agent strait up raping me with rates on one of those, an 11 year old car on the other hand slides under the radar quite well

Tee-Dot · 12-01-2009, 10:20 PM

Insurance isn't going to cost near as much as the labor, parts, and stress of trying to get a K20 into your 11 year old car.

Then try selling it in a few years!

Mrgarrison · 12-01-2009, 10:24 PM

yea . . . . i suppose your right, it would still be fun lol

pIERCE · 12-01-2009, 11:08 PM

YEAH T!!!!!!!!1 Why ya gotta be such a buuuuuuuuuzzzzzzzzzzzzzzzzzzz-killlllllll. Rainin' on all these kidz "K20 parades" and sheit@@

if they want the fun....than who is you to stop it?

You don't eve know nothin bout rsxs neway.....dumb nuub

it's been done before, but ask yourself if it's really worth the time and money to have it done. If you're just wanting to be different, then go for it, but if you're looking for power, you're probably better off rebuilding an h22 and going turbo.

I asked myself if doing a RHD conversion was worth it, and in the end, HELL YEA it was worth it. I've never seen another Prelude in my area that's RHD, I'm always asked about the car, and it helps start conversation so that I can pass out buisness cards and get some work

Why dont you come do my RHD conversion

Mrgarrison · 12-02-2009, 08:31 AM

haha awesome way to drum up business lol. I was just kicking it around, i mean for the 5000 bucks i get a new(ish) engine with LSD and more power, with new skunk2 cams and intake and exhaust manifolds it would be fun lol how much would it cost to sleeve the H22, get new forged internals, chip, dyno and add a limited slip diff. then route the turbo tubing and intercooler, don't get me wrong not sayin it is difficult , i just see it being just as expensive and just as much a PITA. The thing i love about the prelude is how well it handles, going fast in a strait line has never really appealed to me much. i think the benefits of the K motor would be totally worth it

however this was a " hey let me get yalls idea on this" kinda post and i get exactly what i was hoping to get, yes's no's and a chance to bang a guys girl ( im gonna hold you to it if i pull up to your house with a K motor in there ) lol jk

SKEW · 12-02-2009, 09:18 AM

From what i know when i thought about doing this swap: i contacted a couple of people who have swapped the k series into their prelude or accord. What i was told from these people who "have" completed the swap is you can use the hasport mounts for k series engines into a prelude(BB4) or use the cb7 accord mounts for a k series motor swap with of course modification. Rywire can convert the harness for $1187 shipped Shift linkage is of course up to your imagination also. Have fun and goodluck
