Astounding work @ruzki !! You're just about as far away from the usual backyard garage stuff we're all used to seeing and doing on here ourselves!!!

Keep the photos coming!!

Thank you Big Steve - Raider ! In fact, I made everything in a small steel garage .. in the backyard

I took the wire which I bent around the Turbo and bolted it to an engine without turbo to evaluate the fitment with Turbo.
The right side was good but one the left side i could see that the space for the downpipe will be very tight.



Downpipe: In the past i always had problems with the downpipe being to close to other parts of the car.
I made a simulation and found out that up to approx. 240kW a 63,5mm diameter downpipe is sufficient so i decided to go with this size.
I decided to take the stock n/a exhaust manifold and build a fixture with guides made out of welding rods to indicate the out most shapes.
This way I made sure that the downpipe will be centred and I could use the stock catalytic converter. (I changed it later to metal one)



I left 2 weld joints unwelded.. readjusted the pipe in the car and welded the 2 remaining joints.
Fitment was perfect this way.



Better welding joints as promised.

Build the induction pipes was straight forward.


All pipes were purged


The wastegate mount was made of laser pieces and welded together.

Oil feed.. I´ll let pictures talk.



Water piping and oil drain was made out of stainless steel and TIG-brazed.




Since Garrett Turbos are using an imperial thread 7/16x24 UNF, I made an Adapter with restrictor.

Amazing work you do!
I think the coupé is such an underrated car, good looking and great handling straight out af the box. I've had 4 or 5 of Them, and wouldn't mind another.
