That was awhile back. I need to call him and order a bunch of fluids.

I couldn't seem to find the unit they use for the 350z HR master cylinder upgrade on Wilwood's website. From what I can see from this picture:



The unit is definitely longer than OEM, but I'm exactly unsure as to how long. Also, the black piece that connects to where the firewall goes is most certainly an adapter plate that allows usage of the OEM holes. This adds more length to the body though, and I think drilling the firewall is no big deal with an angle drill.

Although, looking at this picture, this gives me hope for something though - a banjo bolt setup for the second CMC I linked in the OP will only increase the body length by maybe a bit over a 1/3 of an inch, so it's actually not that much removal necessary from the ABS unit. I'm gonna look into a way to couple the stock hard line, and this SS line together.

No matter how many times I bleed my clutch fluid, take out the air etc I am still having problems once the car is fully warmed up and I start boosting. (Clutch pressure dropping drastically, sticking to floor} Cant even enjoy the car it seems! I took out my shorter clutch helper spring and replaced it with the OEM and it still keeps happening.

The CMC is the only possible thing that could warrant these problems - Already have upgraded CSC -Southbend clutch/SSFW - SS lines.
I'm thinking it might be happening to my car, after hard drives. I had a recent night where I did the equivalent of 8 drag strip passes, back to back. That must have taken a toll on the fluid at least, and that might explain why there was air in my line, as well as the fluid looking wonky. I may have boiled it over.

Yeah, like Spohn said, I think it's a project on hold. Maybe not though! Although realistically, I don't see any way to make an aftermarket unit fit without any drilling or trimming. Unless a completely new, custom unit is made bespoke by Wilwood.
