If this happens this will be great if not there is always a k 24 swap but I will want ac and all accessories to work

 

I think I will dyno it and see if I can get the NA record. Pretty sure CarbonTek hit 200 crank hp. We'll see in the spring probably...

 

This is awesome to follow! An all motor 200WHP Honda Fit is a dream! I honestly wish that the engine was overbuilt enough (like the K series) to handle boost without any worries. I know it's the lazy way but it's also way cheaper and DIY friendly to bolt on a turbo lol. Damn toothpick connecting rods, if I had the know how I'd install the forged connecting rods myself, but that's way above my skill level. I'm living vicariously through your build!

I know the boosted L series engines are getting a reputation for oil dilution, but a pure engine build would still be drawing air at atmospheric pressure so should still have the reliability of the NA L series engines, whilst out performing all but the the best boosted L series engines.

As for torque specs and shop manuals this is the best I have found: https://chilton.cengage.com/home/library
You can buy a membership if you're in the US, but I also would call your local library cause it seems like a lot of libraries have purchased access and you can go through your library website to access the Chilton manuals.

Fingers crossed things ship sooner rather than later, looking forward to your next updates Z062!

 

Well I just got a email from a company that makes turbocharged kit for fits the only thing that they are out of the country for me

 

 

Once I pull my stock motor, I'm going to build a turbo engine. Low compression pistons, pretty much the same recipe otherwise. Maybe see if Web Cam has a blower-cam profile... I figure on 15 lbs of boost, definitely 250+ hp. Golden Eagle are milling my block for ARP main studs from another car. They will tap and insert the block holes for ARP if they can't find the exact matching ones already made by ARP. That and a cometic head gasket with ARP cylinder head studs, the engine will probably hold 20psi. She will be dirty LOL

 

Elpapas- please keep working on that company for turbo or supercharger kits, I've been bugging all the US companies that might be involved in the K swap but not seeing the end of the road so far with electronics. If I can't find a solution, it would be great if you get something going.

Edit- Z062Fit, how much do you think you'll have into the engine by the time you get it back together?

 

Love the how your thinking

 

block 3gs, head 3gs, cams 850. Gaskets etc 500, tune $1500, CarbonTek intake mani 1400, throttle body 250? $10,500... yeesh. Paying the cost to be the boss...

 

What happens when you run out of fuel on injectors/high pressure pump/low pressure pump. Do you have parts in mind? Are you gonna stick with direction injection or does the new intake allow for port injection?

 

I was just looking today to see if they make aftermarket direct injectors... if I tune for e85, that consumes 30% more volume. I want to spin to 8500 rpm. I have asked both block and head builders to do their magic. I'm getting the bisimoto cam specs next week, well if they release them. At high revs I bet the injectors increase duty cycle, and then with the e85? Uncharted territory bro...i want to have javitune in Miami do the tune...

 

nice love that you are thinking of thinking in the fly

 

Maybe the factory DI pump and injectors from a Civic Type R are a drop in? That or going with an XDI pump and injectors may be your only option if you don't want to run a complete port injection in addition to your DI.

Honda seems to spec their factory fuel systems with pretty low output in mind. Even the DI system in our 2.0t Accord gives up somewhere around 310whp on E40. E85 isn't even recommended due to fuel system constraints. That means the factory fuel system in the Accord only supports about 60whp more than stock. I'm betting the DI system in the GK gives up before 200whp. Less on E85.

 

CarbonTek said they still had duty cycle margin at 200 crank hp and they had not modified the fuel system. I think E85 may be a bridge too far. Probably going to have to use/tune with Torco since i bumped the compression on the pistons...

 

200 crank could only be 180ish whp which would put my 200 number in line with possibly being max. And, that would be on E10. Like you said, E85 is likely not possible. Even E30 may be a stretch.

As you already know, DI makes it much tougher. There isn't really any way to "modify the fuel system" that doesn't involve really expensive parts. You can upgrade the in tank fuel pump for cheap, but that won't add any capacity without upgrading the DI pump. Even then to get a real gain you usually need larger DI injectors. Now, sadly, we are over $2,000 in parts.

Lots of people are modifying Civic Si's. Maybe you could score take off injectors and DI pump from one of those? I'd be surprised if they aren't a drop in since Honda is pretty good about being modular.

It would be nice if something like this were available - https://www.full-race.com/store/hond...-type-r-k20c1/

Meth injection is always another option for additional fueling and adds cooling benefits similar to E85.

I know you already know all this stuff, but sometimes it's good to throw all this out there for others.

FWIW, I pushed my last DI vehicle right to the limit of the stock DI pump and injectors and then drove it like that for a few years with no issues. I replaced that vehicle with a new Ford and am thrilled to now have both DI and port injection stock. Way more headroom

Edited to add - love your project and can't wait to see the developments.

Block sent to CSS? That's where I'm looking to send the spare L15a that I have for our GD.

 

that is a hot interface. Yeah, maybe I go with one of those and quit the DI. The civic parts are a good plan. Also wondering if I can upgrade to the turbo oil pump. I asked the question but never got a response...

 

I don't know why, but I had it in my head that you were looking at forced induction with this build. With the N/A build, your fuel system might be enough if it can support 200 crank.

Take a look at Cylinder Support Systems for your boosted build. They can greatly strengthen the block. Claim the block is capable of holding 600hp with their inserts installed.

I'm looking at them for my bottom end build and Bad Guys Worldwide for the cylinder head in my boosted build.

 

Golden Eagle are probably the nation's sleeve install leader. And they're honda fans, pretty big scene in So Cal. I am considering making a turbo intercooled version of my current motor next (in a couple years). I would probably go port injection, with a manual boost controller, and an air to air intercooler. I'm considering removing all A/C components permanently when I swap engines since this car is rapidly moving to track only...

 

I couldn't find anybody to commit to the head. It's costing me $500 extra to send it to Turkey but they have a CNC port, have oversize valves, springs, and retainers available, and are the only ones who repeatedly have worked on L15B1s, so I'm not leading the discussion on the art of the possible...

 

Is your block getting sleeved? I wasn't aware of anyone offering sleeves so I was glad to find CSS as an alternative.

Here's Bad Guys Worldwide in case you want to check them out - https://badguysworldwide.bigcartel.c...ad-package-l15 I don't have experience with them, but they regularly post their L15 builds so I know they have experience.
