I've been lurking on FF since I got my GK5, but this got me excited enough to make an account. I have been mostly doing small mods here and there. I installed a catch can late last year but was looking for power. I just stumbled into this company, they seem to make turbo kits for the GK5, as well as super chargers. I can't find any good info in English, but it looks like kits are in the $5000 range. Has anyone heard of this company? Anyone read/write Chinese able to give a better translation?

I am a really big fan of the OEM look using the factory airbox, although I wish the rest of the plumbing was matte black. One of my biggest fears with aftermarket air filters is ultra fine particles not getting filtered and sanding the cylinders over time. I want to drive this car for 10 years if I can, and having a reliable way to increase power is hugely appealing.

I really hope there's some Chinese speakers here who can give us a better idea of whats going on.

Thanks, and hello FF community!

 

Never heard of them but seems to be the only one making turbos kits for our fits are chinese.

Yeah, I am down with it. I like the fact you don't have to swap engines too much work. I like more power as well. Definitely interested.

 

Considering my stock Fit blew up at 80K by the piston seizing and throwing a rod. Another posters Fit blew up just short of the Warranty. Good luck with adding a turbo and expecting to run the car for 10 years.

Have you picked a GK5 engine up? I have. The whole thing including intake and throttle body weight is maybe 150#? I'm guessing since it's cheap economy car there isn't a whole lot of exotic materials in the engine. That being said with the weight I'm guessing nothing is designed to be robust and handle more power. I give your car one year or 10K max if you turbo the stock block before it grenades

 

I certainly hope your experience isn't typical. I always though that Honda Fits, even the latest direct injection models were relatively well built and reliable.

Bisimoto states the stock connecting rods would probably be the first point of failure. I don't think I would want to run anymore than 5psi of boost without upgrading AT LEAST the toothpick thin connecting rods to something more substantial. But then with each increase in power comes an associated need to upgrading everything else, brakes, suspension, etc. 5 psi of boost is exactly where I want to be in terms of how far I want to take the car.

If you're correct, there's no potential in the L15B engine, and it's all about the K-swaps, or the L15 turbos out of the civics.... That's sad. I really am a fan of maintaining a factory layout.

I'm tempted to email them in English to see if they respond. You can get a good look of the exhaust, it uses the stock down pipe from the second catalyst downwards. Also the turbocharger itself is TINY. On one of the photos, it looks like the oxygen sensor was plugged into the down pipe, but all the other photos show it being plugged into the original 'cobra head' section of the exhaust side turbine. Oil lines have a hard line part way (I guess to keep rubber from coming close to the turbine?) and then normal hoses the rest. Curious wheres it's tappping into a high pressure engine oil line. I don't know what the third line is for?
I wish there was more info, does this user stock injectors? Does the tuning box have to be used or is there a table that can be loaded via KTuner? Besides the people who have commented already, is ANYONE brave enough to run 5psi on stock internals?? (Much less the 2.0 bar they claim does 250+ HP and 500+ Nm torque... absurd thinking a fit can produce that much power or handle even half that torque)

 

This guy ran 5psi on stock internals with a Ktuner, but unfortunately didn't post as much detail as I would have liked.

Yeah it seems like 5psi is all people feel "safe" with. But I agree I wish there was more information. How reliable is 5psi? I'm tempted to keep an eye on this and pick it up once my warranty expires.

 

There's really not enough information out there for anyone to say, since there's only the one guy on the forum who tried it. Sample size of one doesn't really tell us much, especially since he's not really an active poster.

 

Saenz connecting rods that are for the 1.5ltr Civic Si should be able to fit the GK5 application. They are 10.3 compression ratio too.
