Why thank you! I have more bodywork yet to do, but hopefully soon I will be ready for paint. The color I chose is 2014 Porsche Cayman Metallic Mahogany. I saw an RX7 in a similar color years ago and fell in love with it.

I was a little disappointed in my last exhaust, so I took the time and did it right. This is a full stainless section off an E36 M3. I made an adapter from 3.5 to 4.5" then back to dual 2.25".

Left it sticking out as far as I could, for the boso/shotgun style look, but with a muffler so I dont get pulled over everyday like I did in my AE86. :bigthumb:

Bracket I made for hydraulic handbrake. Two pieces of 3/16" angle welded together. The square piece with round hole, is a spacer for the rear, where the trans tunnel dips, to keep it level.

All done, bled and center console in. It works, needs a LOT of pull to engage, but works great. :dblthumb:

Got my JGS wastegate welded to the stock manifold. Used a 1 3/8" hole saw to bore the port, then ground it all smooth, and welded the adapter using NI55.

Wastegate mounted, and 1 1/2" screamer pipe. Im so glad it turned out good. Miraculously the hood shuts over the pipe, and my hood pins perfectly! :biggrin:

Not sure if I missed it somewhere, but do you have your heater core hooked up? If so would you throw a couple pics up of the clearance you have back there? Thanks

Ya I just had to get a pair of 5/8 to 3/4 adapters cuz the RB has 3/4" outputs. Pretty straightforward, just ran forward most one back under the intake. I actually cut a piece of the VG aluminum coolant hardpipe to use so it wasnt all floppy heater hose. Lol

Close proximity of wiring caused a melting issue.... :mad:

Got the steering rack spacers on, had to cut about 3/4"(19mm) out of RH tie rod, if anyone is curious. Theres a write up on here detailing that, so I didnt bother.

About to paint my car, I will post pics in a few days, hope it turns out ok! (50ft/driftcar painjob id be happy ) :)

Trying to get my Holset mounted, looks like I will need at least a 1/2"-3/4" t3 flange spacer. Getting real tired of waiting on parts.... :facepalm:

Couldnt find the fitting I needed for oil feed from the block, factory is banjo with M12x1.25 bolt, so I drilled a m12x1.25 bolt out, and welded a -4 fitting on for my feed line.

Image

Also couldnt find divided t3 spacers so I welded some dividers into some undivided spacers

Image

And to adapt my MAF to the 4" holset inlet. I made this out of a 3-4" exhaust reducer, and welded a 5/8" heater hose fitting for my pcv hose

Since I figured it out, ill post it here, lol. I just finished installing a SAFC and Bee*R limiter. Now just need to get it dialed in a little more. I like the way the SAFC fits where the BOSE stereo grill used to be.
