Just wanted to give a heads up...

Our Fit is currently at a fabricator's having a custom turbo kit made. He has done a couple of Fit's before including his own personal Fit so he is no stranger to the platform. However, he didn't make jigs before selling his Fit so he's been unable to make new kits. He does still offer custom sheet metal intake manifolds, but wasn't able to sell complete turbo kits.

The heads up is, if you are serious about wanting a custom turbo kit made for your GD Fit, he has my car right now and can use it as a mule to make a kit to your specifications. The kit I'm having made is based off of a T3 Garrett GT2860RS with v-band exhaust outlet, v-band wastegate, etc. His other builds were based off of TD04's. He can basically build a kit based on your goals, budget, etc., but only while he has my car sitting there as a mule.

If you would like his contact information, please private message me. Keep in mind that, even if you elect to source used/cheap parts, this is not an inexpensive endeavor. There's a significant amount of fabricating time required and raw materials (tubing, couplers, fittings, etc) are NOT cheap. Not saying this to discourage anyone. I'm saying this so that we don't waste his time with inquiries about making a $1,000 or even $2,000 turbo kit.

 

Except putting a home made "turbo kit" on a stock engine is a complete waste of time and money.

 

Troll somewhere else. It's a total waste unless you want to double the horsepower.

The stock L15A1 holds 8lbs of boost easily. Beyond that and you need stronger internals. Thankfully, those are easy to get. There are no less than 5 rod manufacturers and 4 piston manufacturers that make parts for the L15A1.

Perhaps you are new to the Fit world, but when the GD3 came out in the US there was an explosion of aftermarket support. HKS, Greddy, and TopFuel made turbo kits. Kraftwerks made a supercharger kit. All were 100% reliable and worked great. However, due to the age of the car, no one makes a kit anymore and sourcing a used one is next to impossible. Not to mention that the used kits are now over 10 years old. It's conjecture, but I'd say the soft GE Fit and then the even softer GK Fit led to the demise of any real aftermarket support for the Fit. In 2007, Honda gave us hope with the GD. They then went a different direction with the Fit and aftermarket companies lost interest.

So, the best option for someone that wants to add boost to one now, is going custom. Custom does have one major advantage over any of the "kits." The kits were all designed around low boost and a stock motor. Neither of those are where I'm headed.

 

Actually, the GE was significantly stiffer than the GD. I think it's the ride comfort/quality that was softened up, which is understandable, because the GD is very harsh.

"The bones of the new Fit have been substantially stiffened in the redesign, in part owing to increased use of high-tensile steel in the unit body. Honda claims an increase in front-end rigidity of 164 percent, which suggests that either the engineering department has adopted a new accounting system or the previous unit body employed linguine in its structure. Since we thought the previous Fit was made of pretty stern stuff—an opinion fortified by the car’s nimble footwork—we have trouble digesting this claim. But there’s certainly no question that the new Fit retains the terrier spirit and moves of the original."

If anything, the Fits were never nearly as popular as other Hondas which led to its lack of aftermarket support, compared to other Hondas. Fits are plentily available and people will build an '88-00 Honda as a track car all day long. I'm sure rear suspension design plays a role there, too.

That said, I saw your turbo kit post on Facebook and I think it'll be cool to see an updated turbo kit available for this car. I'm personally not interested in modifying the L-series, but I know a lot of people are.

 

The GE Fit is definitely a superior/stiffer chassis! I was speaking of the car itself getting softer. Spring rates on the GE are like half, cupholders in the dash, higher seating position, etc. They made the car softer overall. Soft enough that my 70 year old Mom bought one and liked it much better than our GD.

The GD Fit was as popular as older Honda's. Literally every aftermarket company jumped at the platform in 2007-2008. Go back to posts on this board from 2007 and 2008 and it was FIRE! Every post was about modifying and making Fit's better. It was an awesome place that was solidly focused on JDM goodness and modifications. It's just my opinion, but I think the aftermarket world was hoping that the Fit was a new CRX and would head in that direction. It didn't. Honda as a car company didn't.

 

As an OG in this community the man speaks the truth... this forum 14 years ago was absolute gold... these days i dont even bother showing up most of the time.. good luck with the kit... are you allowed to share what your budgetting for the turbo and what expected numbers will be?

 

Our build is on the extreme side. Fabricator is charging us $2600 for his part. His part includes supplying the raw materials for custom intake and exhaust manifolds and doing all of the welding/fabricating work. In our case, that even includes a complete 2 1/2" 304 stainless exhaust system from the turbo back to the exhaust tip.

I'm picky so we are supplying all of the materials for the cold and hot side, turbo, wastegate, blow off valve, intercooler, polished stainless exhaust piping, resonators, etc. Our build is definitely on the high side as it's getting a real Garrett dual ball bearing turbo, Turbosmart wastegate, blow off valve and boost controller, etc.

All that said, a Fit could definitely be turbocharged for literally a 1/3 of what we are spending. Stock intake manifold, re-using whatever exhaust is on the car, internal wastegate turbo, etc would save a LOT of money.

 

That's kind of what I'm looking to do for simplicity and affordability. Internal gate TD04 or T25, stock manifold (for now) and reuse existing 60mm exhaust. Just want a little more power to get out of the way, not anything to shatter records.

Is this Ethan's kit?

 

Yes, it's Ethan!

I couldn't even source 60mm exhaust anymore. All that is left is 50mm. I have a 60mm Megan downpipe, but the stock exhaust after that is tiny...like 45mm. What exhaust do you have that is 60mm?

Was going to have him cut the top 50mm restriction off of the Megan downpipe and use it, but decided to just go 2.5" all the way. My HFP axle back is also only 50mm so off it goes. 60mm is completely fine for most set ups and I probably would have gone with it if I could find one. Oh well, will be neat to have a custom one off 2.5" exhaust. Hope it doesn't sound horrible.

 

I have a full Meagan system, although right now I'm running a custom axleback with an EP3 muffler.
I also thought about doing a custom stainless 2.5" system and using an Apex'i WS2 or similar, the older I get the more docile I want my car to be while still being fun.
