Can this be done?

I had an EJ8 that I was originally going to swap the engine into, but the car went south and I came across an 05 with a blown motor and rather put the F20B in it instead of trying to sell everything just to find and swap a K20.

I already have:
F20B with LSD tranny complete w/ ECU
"custom" swap axles for the F20 to work with the EJ8 spindles
Hasport motor mounts

What axles would I need?
Are there clearance issues with this engine? What motor mounts would I need?
Would I have to modify the header? (I'm planning on boost down the road, would it be easier to do it now?)
Would I have to get different shift linkage?
Would I be able to hook up all the A/C lines?
Would the steering rack still work?

Basically, has anyone done this? hahaha

I can't find any information of anyone doing this swap. Thank you in advance for all of your help.

 

hmm I think the only compatible swap is the Kswap, very few people have done the Bswap because of emissions laws but those are the only two swaps Ive heard of in this chasis.

 

From the FAQ's and Guidelines:

So, in short, no one has any information on the F20B, because for the money spent you could have a K-series which would lead to better performance figures. No company out there has supported that specific swap idea, so you'd be the first to ever do anything with it.

 

I looked at that h22 but there isn't enough info about since the F20B would be most similar to that engine. Street legal due to year drivetrain isn't a problem (chevy 350 defense). Plus the F20B is an ODB2 engine already. My point, having all the stuff that I already have, if it costs me another $2k to put the F20B in, then i'd do it (labor if not relavant for my situation). Seeing how much a k swap is, I don't see the point as hp is very similar, and it SHOULDN'T be too many more parts needed to have the F20B work. I will continue to research and if I go through with it, I will start a build thread for it. Otherwise I will continue to look for that clean shell needing a strong heart.

 

I have seriously thought about doing this swap, but with a limited amount of time, I decided to maintain a K. Contact InlinePRO, as they have swap kits to utilize an F20, with a K series transmission (http://www.inlinepro.com/s1/p-74-f2k-kit.aspx). At least they should be able to provide you with some insight, in regards to completing the swap.

 

Dude. if you do this..... whoa. HELLA props. F20 is a sick motor, for sure.

 

This guy has an F20B not F20C. It is the accord engine not the engine from an s2000.

 

Awe dammit. You're right. I take my comment back. Party pooped.

 

I still think it would be an amazing swap. I've been talking to my buddy that does LS1 swaps in 240s, k's in eg/ek. He does a little of everything, he's having the same major worry, steering rack & a/c problems. This car would be my daily after I sell my CL-S.

 

do the K

 

If you have the know how and can make custom engine mounts, I would say go for it. I don't really know if the steering rack would give you any trouble. A/C lines would more than likely need to be re-bent to line up with the compressor though. Or you could have custom lines made.

 

Yeah, reading comprehension defeated me!

All of these concerns should be fairly easy to overcome. It's just a matter of actually doing it.

 

I hope they're easy to overcome because I'm going to find out for sure if I'm getting the car on Tuesday. Oh, plus it's an automatic so that has to be done too, but that minor compared to the rest. I really hope there aren't too many issues as this will be my daily like I was saying before (i'm working on getting a 2 door 99 Impreza RS with an STi swap as well)

 

k20whitecivic, i saw that F2K. id kill for one of those i think thats what i might attempt after my k. and they can handle 30 pounds of boost so i think i might make my em2 into a monster after college haha

 

Well, I wouldn't say that the F20B DOHC has comparable power to a K-series... unless you're talking a K20A3. It's lacking in the torque department by about 30 lb/ft, and roughly 10 hp. Plus the power bands are entirely different. You see very little low-end in the F20B, where as the K-series gives you a far superior torque curve.

And, $2k will almost get you all the swap parts needed to put a K in your bay (not including the engine/trans). You could probably sell what you have for your F20B, and get enough to afford a K20A2 engine/trans as well.

Food for thought.

 

The two motors are relative compared to the D17 is all I'm saying. Looking for full K20 swaps WITH the 6 SPD tranny are about $3500 plus all the swap & adaptive parts. If I sold all the things for the F20B swap, I MIGHT end up with about $2500.

At this point, I haven't even bought the 05 yet... Still getting more info on it today. I may try finding an K20 w/ the 5SPD and just cam it but this is still if I end up with the 05.

Thanks again for all the information and it's always greatly appreciated.

 

If you're looking for a simple K20A2 swap, the drivetrain can be found for less than $2500 if you look outside of companies and towards sellers on K-series related forums.

 

Just got the call back from the guy. It WAS expected to be a good deal, but now I find out he's asking $9k rather than the $4k that I was told... WITH A BLOWN MOTOR!!! Looks like I'll be holding onto the F20B til I find a good shell that needs the heart. Thanks again for all of the information.

 

Theres a dude in the marketplace selling his K for $2400.

click

 

He's asking far too much. Clean shell or not, that's above current market pricing.

 

I actually started laughing when I saw that $9,000 dollar price tag! There are much better deals out there, you just have to keep looking!

 

I got it in my 04 em2 it's at 240hp now got it mated to a f22 trans with lsd... And I have raced a few type s and I've won... It's the sir-t version

 

That's awesome! Good luck.

 

Show and tell.

 

I also want to do this swap. Is it a direct bolt on swap
