K20 Fit How To Discussion
 
I have an 07 Fit Sport M/T. And Today I just purchased a K20A2 Complete Changeover swap.

What do I need? Obviously the Hasport Mount Brackets.
What mounts? I have most of the Stock RSX TYPE S mounts.

I know that Jackson Racing is developing the Custom Header for Fitment in the Fit.

I Have the A2 ECU, a Key, and the Cluster from the A2.

I am assuming Hondata is necessary for some reason, can someone elaborate how and why?

Hondata's K-Pro ecu is needed.
K-Series Programmable ECU

Trust me, it is absolutely THE best tuning solution for the K-series, and even on other Honda's as well. You can see Kpro being implemented in other applications such as the Element, s2k, D-series civic, TSX, Accord, etc.

It can disable multiplexor controls and prevent a CEL from coming on on your swap. It can get you to pass OBD2 inspections even if u're not "compliant". Huge tunability, safety nets, etc etc. Tuning is KEY to the success of your K in anything you do. Whether it be staying stock, boost, or N/A. Kpro will be the heart and brain of it all.

I guess There aren't many people here on FitFreak whom would be able to help on this swap, since no one has done it yet.

And I agree KPRO is the way to go with the K20! I Was just wondering since I have all of those components!

i figured by now someone has done it to a USDM Fit. i know i've seen some vids/pix of the JDM Fit with a k20 swap. is the USDM engine bay different? i thought the only differences were cosmetic (bumpers, skirts, etc.)

You have to go with a K-pro man, i's the only way to go and you'll love it, my close buddy has it and i am so jealous that he has the capability to tune his car so easily. correct me if i'm wrong but, doesn't the A2 ecu have an immobilizer in it? so you can't really use it unless you remove the chip or have the key.

Kpro in the US is BASED on th A2 ECU! THey add the KPRO circuit board and USB port to the A2 ECU's for K-series swaps here and is normally the best way to get around te immobilizer!

yeah we all know that, my friend has an 06 RSX's so he had to convert it back to the 03 ecu. I just wasn't too sure if the A2's had the immobilizer or not. i was saying that if you just stuck with the A2 ecu without the K-pro mod, you would have to remove the immobilizer to get the engine to run.

The 2003 A2 ECU that I have does have an immobilizer in it. The car will not crank without recognizing the Key Chip. I have the Key with chip that corresponds with this ECU!

BUT also K-Pro eliminates immobilizer from the 2002-2004 A2 ECU's! You just have to send them your A2 ECU for programming!

Hasport Mount Bracket Kit and Custom Swap Axles are out and on their way to me! WIll post pics when I get them!

dude i am so envious right now!!! jusk kidding
im reallly happy for u! i too have been contemplating on a k20 swap but.... no dinero!, i really hope it goes well and u could be one of the great examples of a k20 swap Fit dat is actually driveable. Good luck on your project.
i wish i had funds to do this too.
one day i will have a k20 Jazz/Fit!

gettinafit 05-15-2007 09:14 AM

Yup and hopefully you can use the DIY we will make for this as a help!

azkikersfit 05-15-2007 09:58 AM

gettinafit
how many HPs is the k20 dat u got?

gettinafit 05-15-2007 10:16 AM

IT's the K20A2 Engine from the US RSX Type-S model Which is the Euro Civic Type R engine! 200hp at the crank!

More pics of my baby!
 
Here are some walk around shots of my baby, and the shot of the cluster and Key!! I also got the type S emblem off the back of the RSX Type-S! Authentic!

Here's an example of what this engine sounds like in the Heavy 2900 lb. RSX Type S!! (In my Fit it should weight in at 2600 lb. and Rev much faster!! robably have traction problems too!)

Enjoy! (Not the best driver, but the i-VTEC Sounds so sweet!)

YouTube - Acura RSX Type-S rolling 10 to 85ish

azkikersfit 05-15-2007 12:58 PM

damn !!!

Could/Did you weigh the k20 engine and components?

What is the weight difference between the L15 and the K20a2 that you are adding to the front, anybody?

gettinafit 05-15-2007 04:30 PM

Hasport did and it is a little over 100+ lbs heavier than the stock L15A

jits14 05-15-2007 05:28 PM

with factory weights and power, power to weight ratio you are just over an evo. Add some bolt ons and you are sitting in evo territory.

that's really good, i knew it wasn't much more. people with older civics that are swapping to B series are also adding weight but no one really complains about that. so to all the people crying over the extra weight of the k20, it's really not that much more, sure 100lbs over the front wheels can affect the handling of the car but it can't really be super bad. just think of it this way, you're driving around with a 100 pound kid under your hood but he's giving you twice the power and then some.
