The Buchka 242 Daily Driver

Yep! Pretty much unchanged from the last update, just been driving and enjoying it. Gonna take it up to Radwood in SF in mid july. Trying to get a carbon hood finished and installed before then.
 
Great work, great car. I just read the whole thread.

BTW, what head unit is that please?

Thanks dudes! That photo is taken from the back seat of @Homer's five cylinder swapped 240. His head unit is a Blaupunkt New York RDM 127, it was their flagship head unit in the mid 90's. Super rare, super slick, European market only.
 
Alex, I’m having a tough time finding pics of your power steering pump solution. Got myself an R53 unit that’s likely going to get mounted next to the charcoal canister. I’m thinking of flaring a bit of the high pressure line to adapt a JIC fitting. Just want to get a look at what solution you came up with.

If you do that, make sure the fitting you use is rated for power steering pressure line use - regular AN / JIC fittings aren’t.

These are the only two pictures I was able to dig up. The one of the pump is real awful and doesn't really show context very well so you'll have to use your imagination. It's mounted on the passenger side of the car, ahead of the wheel and right underneath where the stock washer tank goes. I ended up hacking and slashing the stock Mini bracket and welding it to the frame rail of the car with some random scrap.

The high pressure outlet fitting started off as the stock Mini part. I recall that it's an o-ring sealed boss that sticks out of a plate. I cut the stock hardline off and welded a male 6AN fitting to it. The hose is a stainless braided, smooth bore high pressure PTFE thing I got from Earl's. This mates up to the banjo fitting on the rack with a cobbled together AN6 to banjo adapter.

The reservoir is some kind of ZF/BMW thing with a matching mounting bracket and rubber isolators.

Regular screw together aluminum AN usually isn’t rated for PS pressure, though some are. Aluminum adapter fittings are rated for PS pressure if they’re from a reputable company, though they can fatigue and crack. Brass JIC is not rated for that pressure. Push lock is most definitely not.

Almost anything steel is rated for 3000psi min, 5k is more common. Field serviceable steel screw together JIC is rated for 3,000 psi.

Cool! Thanks. The setup makes perfect sense as you described it. The spot you picked was where I was initially planning on placing it, but thought it would make sense to shorten the wiring and hydraulic hose run; more than likely makes no difference. I have the same reservoir roughly in the same spot, using an E30 bracket on some bent aluminum bar.
 
If you've been following along the Fake Race Car build thread you know my brother and I have been getting pretty deep into composites manufacturing. One of the first things we made was a pair of molds from an original flathood. The mold for the inner support frame was a crime of opportunity to make a carbon replica of a factory hood. Last week we finally got around to laying up and infusing this part.

This part looks fairly simple at first glance but has quite a bit of curvature and detail. This made the lamination pretty time consuming, lots of small details to think through to make the different patches line up well.

Next couple photos show the infusion in process and complete. We tried a new for us type of woven flow mesh in this part and it was great to work with but ended up being a total bear to remove. Stripping the flow mesh and peel ply off took the two of us wrestling with it for the better part of two hours.

Popped out the part and we were both super happy with how it came out. Great gloss and surface finish right out of the mold. Had a few very minor cosmetic pinholes but nothing too worrying. Next step is to final trim and sand the support frame, bond in some metal reinforcements, and bond on the outer skin. Pretty anxious to get this on the car and see how it looks.

Thanks dudes! Pretty thrilled with the outcome to be honest.

Absolutely incredible! Are you going to do a clear top like the early 2000's summit racing honda hoods??

As much as I want to live out my hotboi fantasies I'm pretty settled on paint matching the outside to make it all look stock. Probably going satin clear on the inside to give it some UV protection and so I can still hardpark and floss at cars and coffee
