yes, they are sleeving the block for 75mm pistons (v 73 stock).

 

Their prices are awesome. I think a lot of their L15 stuff is for the civic, L15B7 which I am interested in coopting. Looking forward to your BG build thread where you get it done for $5000 less than me and hopefully have just a hair less hp

 

Takes money to make power 😎

 

So just based on the idea of using Si HPFP on the Fits L15, the flanges on the parts look different. It might be as simple as using longer bolts or it might not match up.

Here's parts for reference:

I also don't know how the fuel pressure regulator is different. Does FI increased cylinder pressure require a relative increase in high pressure fuel to maintain proper injector function?

The easy way out is just switching to port injection, like Bisimoto ended up doing.

That E85 volume requirement is what hurts, need some high flow. Thanks for the food for thought, exciting stuff guys!

 

Block is at golden eagle. Head is in Turkey. I just said fuck it go all out and went with their titanium valve coating, fingers crossed it repels coking. Cams are at web cam Inc in riverside, we spec it over the phone tomorrow. I want to tell them pull to redline, aggressive vtec engagement. I can see 4piston's stage 3 and 4 road race cam specs but for k engines with higher displacement. Crossing my fingers the bisimoto specs look good.
the lightweight flywheel is causing fuel cut at 4500 rpm under wot and part throttle. You come to a complete stop then it's good for a few miles, then cruise and i get a flashing engine light into limp mode until I turn it off wtf? All ideas welcome...

 

That 1.5L gonna breathe alright! Oversized valves with lift and duration. Crazy!

Are you sure it’s flywheel? Only thing I can think of is if the ring gears are damaged (if our cars use it for timing)

 

clutchmasters said it would need to be tuned around

 

Don’t know maybe but the oem one and try it

 

Got an email back from BG, they said if larger exhaust valves were available, it would be $300 per valve to set the head up for them. Does that seem reasonable? My guess is that's not really out of line on cost, but not sure if it's worth the expense.

 

Great photos, Z062FIT. Absolutely fantastic.

I was, however, a bit confused at first, by your orientation labels. Since I depend upon words to orient things in my mind, in addition to pictures, and since I have middle ear problems, the less ambiguous the words are, the better oriented I remain and the less likely I am to feel dizzy and disoriented, lose my balance, and tip over.

For example, knowing that historically most car engines were mounted at the front of the car, and mounted longitudinally, and knowing that the engine in the Fit, a car which has front wheel drive, has an engine that is mounted transversely – we have an engine orientation labelling ambiguity problem. Which side of the engine should we call the "front" side of the engine? Would that be the side of the engine toward the front of the vehicle (labeling method 1), or would that be the side of the engine that historically has been likely to be toward the front of the vehicle, the side that is opposite the side that connects to the transaxle, that is, the side opposite the side with the flywheel, the side of the engine that has the timing chain, the side of the engine that, in the Fit, is at the right side of the car (labeling method 2)?

By the way when I say "the right side of the car" I am using a labeling system that defines the "front" of the car based on the forward motion of the car.

Apparently you went with method 2, and have been consistent about using labeling method 2. It is good that you have been consistent.

I needed to get that all straightened out first, before I could begin to understand what I am seeing in all the photos, and not trip over something and break bones. And, I hope my efforts to define the labelling system in use here are helpful to others who are interested in seeing how this wonderful, lightweight, little 1.5 liter engine, is constructed – an engine from which Honda has been able to produce 130 horsepower using an average of only 1/36 of a gallon of gasoline (0.0278 gallons of gasoline) to move the car a mile.

I am reminded of my 1968 VW Beetle which also had a 1.5 liter engine – but an engine which produced only 53 horsepower and required more gasoline per mile, 1/25 of a gallon of gasoline – despite the fact that the car weighed 600 to 700 pounds less than the Fit. I am impressed by how much internal combustion engine engineering has progressed since 1936. I thought my 68 Beetle was peppy, so you can imagine what I think about the Fit.

You say that photo number 6 shows the "back" side of the front cover. To be less ambiguous, I might have called this "the inside of the timing chain cover." Also, it is noteworthy that we see that the photo is oriented so that the top side of the cover is at the top of the photo.

 

Name checks. Sorry, I didn't take time to organize. Just dig in and it'll make sense. Check the threads I've posted maybe search for "max effort" I forget what I called it. The engine is done but I'm experiencing misfire problems and can't get it tuned just yet. I think I need fuel injectors and was considering the ones from the 1.5Ts but I think they have a different duty cycle. We'll see...

 

"Max effort" thread is here.

 

I like understanding how my engine works and I like being able to troubleshoot problems, and do a proper job of disassembly and re-assembly. I like be able to find ways to make small improvements that make a big difference. For example I like putting grease on the battery terminals and connectors so that I know that the connectors won't corrode and we'll always be getting maximum flow of current. It is a little thing that can truly make a big difference.

 

I agree that all those things are precursors or entry level requirements to where I'm at. Currently, I'm deriving much more satisfaction from constructing a race car. Taking a pedestrian platform like the fit and getting after Porches and corvettes on the track. Unfortunately, I'm alone and unafraid on a lot of these things. Example: I put too much hondabond on the caps that go over the front (passenger side) of the cams. I had Precision Machine in Baltimore set the timing and they removed and detected my mistake. That simple error could have cost me the engine. Really wish I had full assembly disassembly manual for this car. But all said, she's pretty simple now that I've been fully inside every nook and cranny...

 

Does not a subscription to Honda's on-line service manual provide one with complete assembly-disassembly information?

 

When we were able to buy the manuals, they covered everything. Am library out west has the manual available - maybe Chilton's? - but you need a password. Make a separate post asking for the link and the password. I've used it several times, but the P/W keeps changing. If you're ambitious, you can save copies of individual pages on your computer.

Getting back to the subscription, I think you can "rent" it for a day for a reasonable cost.

I found this: Do It Yourself Auto Repair Features and Descriptions by Chilton DIY

 

Personally, I don't trust Chiltons, except as a source of possible extra information after I have first gone through the official service literature.

The Chilton's page you linked to has 2 links, one to "professional" and one to "DIY." That makes no sense to me. Why would someone working on a particular car do anything differently if the car belonged to them verses to someone else? It's the same car no matter whether it belongs to me, or to someone else so it should have the same service literature.

 

The "Pro" manual shows you how to make it look like the job was done, although it actually wasn't.

 

Aha! That's why they have a separate pro manual!

 

Hello, I have a Gk5 2015 rs with l15b1 engine on it. Its a 6 speed manual one, the rare honda fit😅

I want to retune the ECU but ktuner is not supported, how did you got ktuner for yours?basically its the same engine

Find a picture below for my ECU.
