Will this work on the USDM L15A engine? I know almost nothing about turbos and turbo applications.

 

I found this in another thread. Random info about the kit, its not in English though. Theres vids too.

[PR]HKS Fit Turbo

 

While I wish it was out, I called HKSUSA the other day and they said that the USDM version is still in prototyping phase.

yeah i think there was an issue with the lines (brakes, clutch, ABS, etc...) since on the JDM fits thats all on the opposite side compared to US Fits.....

 

Hopefully they'll adapt it soon. The engine is the same as ours, the L15A.

 

It's gonna cost around 2k-3k USD on this kit? (my guess, please correct me if I'm wrong?) and it only increases the PS by 35? I guess that's what you should really expect from a bolt on turbo kit. The engine and its compression rates is so small that it's a waste of money to turbo charge it, I rather save that money for a K series motor swap.

 

i think Blitz and Greddy will release their Turbo kit before HKS. And i also think they cheaper than HKS.

 

I'm not sure about that. As I have never dealt with DBW, but I would think that since the turbo is powered by the exhaust, it should be passive and whatever engine management is used would be able to work alongside with the DBW setup.

However, I would like to talk to the guy who was spraying. I was looking at some direct port nitrous systems however, I only see one that is for DBW

As for back on topic, I think that 35 or so hp for 2K would be a healthy increase in power. I mean, to get the best bolt on parts, T1R intake, and well, any catback exhaust, you are at almost $1K for maybe 10whp to the wheels.

I just hope that someone takes the Fit seriously enough to expedite the kit's we are all waiting for. However, don't rush. I would rather wait for a while for a kit to be tested thoroughly than to have a half-a s sed kit come out and inexperienced people installing these, blowing the engines and then freaking out. Let's just wait it out and pick the best one. These are large companies that can and have the funds to test and develop...I expect them to bring out the snail kits soon but let's just keep our fingers crossed.

We found something that allows you to manipulate the throttle response. It works for the R18 Civic, the K20Z3 Civic Si and the L15A Fit. I can't say much more than that right now as I'm waiting on the videos of the two Civics to be delivered, but let's just say, the DBW throttle (and its subsequent rev hang) is no longer an issue...

 

As I've said before, don't forget to save money for your suspension as well. Oh, and new tires quite often. Heavy engines in an already non-ideal FWD weight distribution scenario usually equates to three things:

1. Driveability sucks

2. Increase tire wear

3. Crappy handling

A 35hp increase (usually those numbers are quoted at the wheels) is far more ideal for a smaller car designed to get great gas mileage utilizing the STOCK engine (meaning no internals) to produce a RELIABLE increase in useable power than swapping in your K-series.

I'm not trying to discourage anyone from the K-series as I'm very familiar with the engines (we're working on some things for the K20Z3 as I type this), but don't knock these companies for what may seem like a small increase in power. T1R, HKS, Greddy, Blitz, and even Mugen understand the benefits of using the stock L15 over a K-series engine in the Fit. Also, we've yet to see the powerband for most of these kits yet. People tend to equate the horsepower increase to top end of the RPM gauge, but more beneficial is an increase EVERYWHERE. A good turbo or supercharger kit (or NA tune) has this. If you're waiting around for the turbo to boost at like 4000RPM, what good is an increase of 200hp? Even still, if you want more out of your engine, use the money you were going to use for the K20 swap to increase the strength and durability of the L15As internals as a precaution (Honda rods are notoriously weak), increase the fuel delivery slightly, give it a slight bump in compression and turn up the boost wick a bit. It'll be far cheaper and far less of a hassle than an engine swap regardless of how cool they may seem.

Unless of course, you really have a purpose for that K-series motor...

 

I think that HKS already released for US FIT for Sept 2006 onward as it said on the web for the MT? It also said the ECU part # for US Fit reference?

1. Selling country => USA
2. Year => 2006/09 onward
3. MT (ECU) => （37820-RMA-A14)

 

Again, I called HKSUSA the other day and they said that it is NOT released in ithe US yet.

Good point also Claymore about the TB. Crap! Oh well...Someone has to come up with something soon.

Yeah, but you're saying that as if it's a HUGE problem. It might be a minor issue for the R&D team because as you mentioned, it's not a direct bolt-on (I didn't say it was), but that's not really a PROBLEM-problem. The real issue would be if Honda managed to do the same thing with the Fit's ECU as they did with the K20Z3 ECU. Don't even get me started on that....WTF were they thinking?

I don't think they did though gauging by some of the DIYs here.
