That's not me, but a friend of mine who has the same last name, strangely enough.
He did do the intake and exhaust fabrication on this car though, which is why the exhaust is a bit of a work of art! I do enjoy seeing nice big 3" stainless mandrels joined together by tiny uniform TIG welds with V-bands at every connection.

I've had a couple questions about what it takes to build a setup like this, so I'll add in my comments:

I think the cost would be in the range of 5-6k to have it done properly. Labour to install would be at least another 1000 I'd bed. I don't know how many would really want to spend that much on a Fit.

The most difficult part is the tuning. Piggyback ECU's are a bit hokey, but that allows the OEM ECU to take over and offer the best closed loop driveablility. Stand-alone would be difficult to get tuned for daily driver situations like cold weather, hot start, etc... So until hondata has a flashpro for GE fit, you have to put up with a piggyback trying to trick the stock ECU.

Other than that, it is just like any other turbo build, so if the builder has turbo experience, they will know how to do the charge air plumbing and oil/coolant plumbing.

I'll put together a parts list with some price estimates and labour estimates and see what the numbers work out to.

Hey, just found where we have a bunch of photos of the Fit build:

There are actually photos dating all the way back to the beginning of our Associate racing team. Lots of great memories, starting with that blue 06 Civic Si.

What intake manifold are you using?

Bisimoto aluminum fabricated plenum manifold. We were concerned about the stock resin plastic manifold taking so much boost pressure.

So, here's what I think would be a realistic budget estimate for 200whp turbo from GE8 Fit with a streetable full exhaust. Ours was making 215whp with a catless 3" side exit straight pipe exhaust on 91 R+M octane.

It works out to $6000 + install labour and tuning. I can share the maps I have for AEM FIC-8 with MAF and MAP clamps, but would require fine tuning at a dyno with a sniffer wideband.

Of that total, $2300 is estimated for custom fabricated parts that I could assist with providing.
The remaining $3700 is estimated for generic parts that need to be acquired. This estimate is for a quality setup, similar to what Full-race provides, and parts could be interchanged with equivalent parts to reduce costs.
For example, one could go with a much cheaper turbo, but it wouldn't spool as fast. And the EFR has an excellent internal wastegate, as well as an ingenious built in recirc-BOV.


Parts I could supply:
Turbo manifold (TIG welded 304 SS)
$300

Downpipe to cat (TIG welded 304 SS, with flex-pipe and upper v-band flange)
$500

Intercooler with custom end tanks (TIG welded Al with mounting brackets)
$1000

Charge piping (TIG welded Al with 3-ply silicone couplers)
$400

Other parts you'll need:
Borgwarner EFR 6258
$1,631.53
BorgWarner EFR 6258 Turbo - Full-Race.com

AEM FIC-8
$599
AEM FIC Universal 8 Channel Piggy Back 30 1930 | eBay

Walbro 255lph fuel pump
$79
Walbro Fuel Filter: Yard, Garden & Outdoor Living | eBay

0739

RDX 410cc injectors (4)
$160

Oil cooler
$99

lines and fittings: Oil feed, oil drain, coolant
oil drain fitting in oil pan
~$200


Battery relocation, or smaller battery.
$200

appreciate the breakdown of components. doesn't seem all too bad, considering the outcome. as far as the turbo manifold, are you having a pipe bolted directly after the cast oe manifold? Are you able to make another flange for the turbo inlet into discharge and outlet to the downpipe? if i were to do a turbo setup, i'd try to be more budget-friendly, especially with the turbo, (if my other car doesn't have an efr, my daily isn't going to get one either!) maybe something like a take off td04 off of the subaru's/saabs or another OE turbo take off that can be had for relatively cheap.

As far as heat generated, are you recommending an oil cooler, even for the daily driven, non-tracked applications? I'm wondering how hot these engines run, thinking that an upgraded radiator would be a better option over the oil cooler (just realized that the oil cooler is $99)? want to make one for my s2000?

Yes, the exhaust manifold is very simple. Its just a transition from the OEM integrated exhaust manifold outlet shape to the turbo inlet shape (T25). Have a look in the gallery for photos of it.
The EFR has a standard T25 inlet flange, only the outlet is V-band. So any other turbo of appropriate size would be T25.

The exhaust housing outlet would just have to be matched to the downpipe, whether its a V-band or GT28RS or whatever...

Turbos generate a lot of heat, so that's why I'd recommend an oil cooler.
A larger rad is also a good idea too. It depends on how hard you drive on the street.
If you were trying to simplify, you could upgrade your rad and then install an OEM oil-to-water donut cooler from an S2000.
But oil coolers are cheap, running the lines is the most challenging part. And since you'll need another pressure feed line for the turbo, it makes sense to since a sandwich adapter will have a couple extra feed ports that you can use for the turbo oil feed so you don't have to tee the oil pressure switch port.

How much boost were you running on the stock internal set up?

We had peak boost of 13.8psi at 6800rpm on the stock setup.

thanks for the insight. do you have a link to the gallery? i'm not seeing it in this thread the rdx injectors are drop in with splicing needed? or plug and play? also, what kind of intake system are you running? short pipe to a filter?

for me, the fit as a daily driver is very ideal, the only thing missing is a little bit of power. I'm not too power hungry with this car, but an additional 30-40hp would be sufficient for me so I definitely would like to go to more budget-friendly items. with that said, are you able to construct intercooler pipes that would mate to a different core, like a take off from an evo?
