After not too much thought and much more research I've decided I want to swap the K20z3 into my Fit. Unfortunately with how new the '09 is, there obviously isn't much of an aftermarket following for it. Doesn't help that nothing from the '08 is similar from '09 models, from what I've read.

I've already talked to Hasport and they informed me that unless some big names like Spoon or Honda themselves ask for motor mounts, they probably won't produce them for a long time, so I put a little birdy in Spoons ear and their response was: "Yes, we plan to put the K20a engine in one of our Fit race car. If you are interested in the K20a mount for your Fit, email me exactly what engine you plan to swap." So expect to see this eventually, but I expect Hasport's story to be the same with other companies as well when it comes to aftermarket for the '09!

Basically, my only concern is whether the K20z3 will fit into the engine bay of the '09 Fit Sport? I know the K20s have been shoved into the earlier models with minor fab but I just want to make sure the engine will fit before I start piecing together parts as I'm not to familiar with K20s or previous model Fits. Please, if anyone is familiar with engine/engine bay dimensions, could you help me?

 

I can't remember who, but a companies already done it in japan, here's a video of it on youtube

A z3 should fit since its pretty much the same size as the K20a and the mounting points are the same.

You might want to consider using a k20a series (a or a2) engine though because there is alot more aftermarket support for it. You can get k-pro for the k20a and k20a2 which allows for custom tuning if you want to go that route.

 

yeah. since its drive by wire you only get the hondata reflash. there is actually more modificaton than you think and lots of misc. stuff that was needed to do the swap.
the engine barley fits in the GD3.

the hardest part was this harness since you are running 2 ecu's

 

hondaf1racing: Yeah, I thought about it. I wanted a K20A when I had my EK hatch before it was sold. But I don't have that kind of money with a brand new car and baby on the way, so I see going the K20Z way will save me at least a grand from the shopping/browsing I've been doing. And for ~20 extra horses, don't know if it'd be worth it, especially after reading about all the traction issues the K20 swaps produce anyway.

redrumm: That's what I've been reading about: having to cut/reshape the engine bay to keep it from knocking when you WOT the thing. I guess there's a way to keep the e-Throttle stuff. I think I was reading something about a programmable accessory that can tune the e-Throttle for DD, Sport, and Racing and it changes the response timing or something...I could just be making it all up tho!!! But I do kinda like the e-Throttle for some reason. All in all, I think the other stuff should be easy; the ECU part is going to be the hardest, and there's nothing else to do besides pull out the manuals for both and start splicing until Hondata/Kpro come out with a plug-n-play cable!

 

as i always say. if your not looking to make more than 200hp then just keep your stock motor and boost it

 

in Asia there are a lot of 300whp+ Fits on boost l15. forged internals + bored intake mani. look em up.

 

I would, but I like the idea of having my stock engine to go back to in case I do something really stupid! VTEC...BOOOOOOOM!!!

 

? that makes no sense. you would do a k swap and if it blew up go back to a L15?

 

any links? that would be good info

 

not really.. if you blew the k would you rather not drive your car while its being fixed or replaced? id sway the l15 back in just so i could drive it..

 

That's my thought process...that way I'd have the K out to fix whatever happened to it, while still having a second car around the house.

 

you wouldnt even have the mounts for it anymore and then you would have to undo all the spliced wiring you did to install the Kpro. you could probably buy a k20a3 to hold you off for awhile since you can find those for cheap

 

I wanna see some articles on the 300+hp l15's 1wayfit. I could see 200-250 but breaking 300 is perty nice. Anythings possible it's just the mods you have to do/the hacking you'll have to do to get the engine in there. Be nice if a person could get a block to fab from first before diving into it head on.

 

its probably already going to be achieved here by the end of the month.


i still want to see a E85 tuned fit

 

wouldnt even be able too. i would sell it and get some money off of it

thats like saying i just did my H22 swap into a civic but it blew up so im putting the D series back in?

 

yea, i'd like to do e85 n see what hp you can get with it

 

I don't know enough about the L15->K20->L15 swap, but this guy seems to and it seems like he had it in his mind to swap back to the L15 while he rebuilt his K20...can't remember what page he said it on, tho... So, why wouldn't you be able to (just asking from a standpoint of no experience in this area) Thanks for everyone's input, still!!!

 

because you already hacked up the bay to have the motor. K motor mounts wont work with L motor and your running K pro which does not work with L motor.

your pretty much going in reverse. im not saying you cant but it would be a waste of time IMO.


you can serioulsy buy a k20a3 from a base model rsx/civic si 02-05 and run that. ive seen these go from 500-800 complete swap
