Is that like a complete interior CF overlay? Cool hahah, I saw one other person with something similar, who makes that?

Nice choice on the Quaife! Essentially a lifetime unit... I think if I ever do install my LSD it will officially make the Fit no longer a daily... (clutch type, gotta keep up the fluid maintenance )

I've owned a lot of rigs with LSD and I wouldn't worry about the maintenance, the LSD doesn't affect it that much, on a auto I would install a very good filter in the cooler line just for extra cleaning..

A clutch type LSD has a pretty specific maintenance schedule and is very different in function to the typical viscus or gear types. Here is a great explanation and break down:

MFactory gears are in

Nice read regarding the LSD. Thanks for posting it. Tranny gears look sweet

I had about 4 cars with limited slips before the gear and viscous units were invented.... Dana Power Locks, Detroit lockers, Rockwells, Eaton Gov-locks..

All the clutch type need is the correct friction modifier and a regular fluid change to keep the fluid reasonably clean. Its way too easy to overthink this stuff.. Especially when oil is involved.. (Always need another oil thread right? )

A clutch type limited slip really has no more wear and tear than the typical automatic transmission clutch pack or band assembly, and how may autos have you run across with 100+ thousand miles on them and never had the fluid changed..

I currently have ARB air lockers (Air engaged spools) in my 4x4 and a detroit locker in the Ford mustangSCCA car I tend to. Also have an old truck with a Plain old dana posi, 400K miles on it. it gets new fluid every 5 to 10 years wether it needs it or not..

The problem with gear drive limited slips is they seldom tolerate high torque applications, drag your OK but if you have to turn and there is more than about 300ft lbs of torque they tend to have wear issues. In a lightweight car its probably never going to matter.

Similar with Viscous Diffs , they wear out more quickly if beat on hard, IE high horsepower and lots of slippage required like a corvette/audi/STI running autocross. The upside is usually they just boil and once they cool they are fine.

took a trip up this morning. Sorry no teaser pics


sway bars, shifter, shifter bushings are in. Dropped off the tranny parts and underpanel.


They put a Walbro 255 in. I could not believe how small our fuel pump is LOL! Fit in the palm of my hand.


We went over pulley design and they are in fact making an adjustable cam gear. I heard that a few FitFreaks had already called him


The pistons were ordered at 11:5 so they would have extra material to remove. Actual compression TBD.


Flywheel and clutch were all warped from heat!!! The Exedy stage 2 was a bad idea. All new stuff coming.

Hahaha, you bet I messaged them on that cam gear!

I'm looking at a ClutchMasters FX350 for my build... I really like the idea of the upgrade to 212mm and a matched lighter flywheel

Yeah I saw clutchmasters was offering stuff for the Fit. Not sure what I will have yet. The companies that these guys work with are mostly for drag I think. The head gasket was custom made also.

I think my engine will have some interesting parts. Kind of a Frankenstein L15

Cometic builds custom head gaskets... $$$$ they have a metal o-ring in some to help hold the boost in. The ring "cuts" into the head and block to seal, they need to be torqued very carefully.. And some need re-torqued..

Oil coolers,,, Setrab.. They make them in lots of sizes and they also own the patent on the stacked oil cooler if I recall. (Pegasus in England sells a lot of cool stuff good source to surf just for ideas.

Drive up today and got exciting news and saw some teaser pics.

Head came back early!!!!! Close to 30% more flow over stock!

Fuel rail is done and will be anodized blue. 3/8 fuel line as well.

Waiting for cat cam custom grind.

Stainless Intake valves. Iconel exhaust. Stainless springs.

Custom made bronze valve guides and keepers.

Next week he is boring out the block and clearancing the rods.

Still waiting on the adjustable cam gear. He was going to cut out the inside and replace with an adjustable piece but it is hardened steel so he will make one and have it hardened after.

Axles will be done in a couple of weeks.

Engine should be back in the car when the axles are back.

Then he needs to make a custom header, intake manifold, piping, etc... Then time for tuning
