So welcome to my build log, this is sort of a build log slash restoration log, I'll make a list of things I want to do and things I've done. My goal is to restore this car as I can with better upgraded parts and eventually install a supercharger. I'm open to any and every comment or suggestions! I also want to thank all my sponsors, I really appreciate the support!

I just want a shiney set myself. I have about 10 cans of plasti-dip, but have stopped using it as I don't seem to have the best luck with it.
Plastidip has it's learning curve for sure, I'm excited to try out hyperdip instead, seems it's quite different from plastidip, it's thinner and less viscous, so more like paint as opposed to heavy layers with plastidip.

You will need a pretty big tub to be able to dip a rim into it and some strong arms.

I've actually found PlastiDip to be one of the easiest "paints" to work with, assuming it's not too cold. It's always laid down incredibly evenly for me - just don't go too heavy on the coats if you have things taped.

hyperdip, not hydro dip 🙃

I just posted my excel spread sheet I use to keep track of everything and how I calculated approximate output

What's your game plan for making that thing work?

I'll be making an adapter plate (already made a prototype drawing) to adapt the AC Compressor bolt pattern to this superchargers bolt pattern. Since I didn't have AC to begin with, I'm saving having to delete the AC system! I posted the excel spread sheet, check in the second tab, there's a bunch of pictures I use for reference and they show quite well.

I saw in your spread sheet that you need some 40+ lbs injectors? I'm actually upgrading from 465cc (~ 43 lbs) Deatschwerks injectors to 650 cc (~ 60lb) injector. The have about 5,000 miles on them. If you would like to buy them they are yours. I'll even throw in the OEM fuel rail if you want it. PM me if interested. I'll accept any reasonable offer.

**** 1.8L not being able to take in those injectors lol
Intercooler is here! I got a heck of a deal on it, I almost think it was a pricing error on Amazon lol I came to about $60 USD to my door, shipped and sold by Amazon 🙃

Got my new shift knob yesterday, boost gauge arriving today, as well as new muffler, resonator and the bypass valve.

ordered some aluminium zinc brazing bars, bondo fiberglass repair kit, bondo body filler, rust reformer, dremel cut and grinding wheels, carbon fiber duct, gasket sheets, idler pulley, undercoating, torch tip, brushes and gloves.

I already have a full scratcheshappen kit with my color paint in it and will order more paint cans if needed, got to go get some propane tanks and expanding foam now.

Oh and gave her a good rinse, with my doggo.

So yesterday I installed my new resonator, sounds way better, can't wait to install my muffler too!

I got my bypass valve too (from a 2006 mini Cooper S), it's so small and cute haha

I went ahead and designed a plate to be able to mount it to the Type RS BOV mount charge pipe section. I'll probably am gonna 3D print it, or I could cut it out of thick acrylic I have here too.

So here's what I have to adapt. I would go with the creative spridgets plate, but shipped with duties it comes to almost 120$ for something I can make myself. First I'll be making it from quarter inch plexi see how it turns out. Oh and you can see the Dayco radiator hose I will be using for the bypass tract on the right of the picture.

Ordered M8x1.25 bolts, nuts, lock washers and regular washers along with an aluminium plate and tubing to make shims for the supercharger. So far I think I'm gonna make it out under $2k CAD!

I put in a lot of work yesteday night to fit the exhaust parts I have better, lowered the car and in my tired self, I had routed the exhaust between the z-link and the cross member to which it attaches to, so it did not clear with the coilovers. I raged a bit let's just say.

On another note, I took the stock intake casted tubing and cut it to prepare it to braze some plate to it to create the inlet and outlet for the supercharger itself.

Next big step is taking measurements from the mounting points off the AC mount, something I have not been able to find online. With these measurements I can then finish adapting it for the supercharger.

Hopefully this weekend, I get some time to work on it.

Big things coming in the coming weeks. Routing the charge pipe from the throttle body up to the intercooler and braze some sections where possible. Mounting the supercharger (make the bracket). Finish my adapter plate for the boost gauge and AFR gauge off the template I made this weekend, then heat shape it to fit the trim.

So yesterday I finally was able to recover the flange portion of the cast intake piping from the Mercedes designed inlet/outlet for the supercharger to then aluminium braze my own plate and tubing. The red part is the shape of the flange that I took out from the original casting. I drilled probably a hundred holes around the flange then cut between each to recover it. Now I'll need to sand the surface flat enough to braze some plate on it to then make some holes to fit the 2.5" inlet and outlet tubings.

The picture below is not mine, but it shows both parts to give you an idea of what I did.
