I've been meaning to make a build thread for months now.

If anyone is interested in the history of this car (October 2014 - May 2018) i have somewhat of a build thread on that other website under the username 8990q.

Last year the car shut off on me and would not re start. I thought it was the distributor. So i installed a new one and turned the car on and then proceeded to listen to the valves hit the pistons. Turns out the distributor was fine but rather the timing belt slipped and while installing the new distributor everything was in time other than the cam gear. I'm sort of happy that happened as it is what caused me to do this build.

Here is the current setup

Engine:
-3b block 82mm bore
-FRP 9.1:1 pistons
-Scat rods
-ARP hardware
-Coated bearings
-Supertech valve springs
-terrybullowon timing gear
-Autotech cam gear
-Tubular SS manifold
-Holset hx35 (turbo lab of america 0.82 ar exhaust housing)
-Eaton m62 (AAN crank pulley machined to accept supercharger pulley)
-Nissan throttle body as supercharger bypass
-Mishimoto Evo 10 3" thick intercooler
-Coil on plug conversion
-Vems

Drivetrain/Suspension:
-6 speed 01e
-Sachs zf clutch
-KEP 6 puck ceramic disc
-4kq driveshaft
-custom coilovers (koni struts & eibach springs)
-5 lug conversion (b5 a4 rear hubs on all 4 corners
-200 20v BBS wheels
-Coupe quattro g60 brake calipers
-4kq front sway bar mounted in the rear

Chassis/misc:
-Electric power steering conversion
-b4 cabrio carbon canister mounted in passenger fender
-wiper fluid reservoir mounted in drivers side fender
-JHM b5s4 solid shiftier modified for b3

Here are some pictures i took along the way. Currently the car is done in terms of fab work and whatnot. Still have yet to start it or drive it but that should happen any day now. Everything in terms of supercharger control/wiring and plumbing is in place. The plan is to first do a break in with just the turbo at spring pressure then eventually get larger injectors and throw the supercharger belt on for some twincharge goodness.

I didnt do the best i kind of rushed it but its the perfect size.

Also the brand name is "royal imports" which could not be more fitting haha. It has a little logo on the bottom of the vase.
