So do you have some fabwork left, and then you are ready for tuning?
Yeah I still have some work left. I have to fab up the exhaust and the cold side still. I also have to finish welding everything. So far everything is mostly just tacked together. I think I'm past the hardest part though. Just making everything on the hot side fit was the biggest challenge.

I still have to run fuel lines, wire up and plumb the boost control, and figure out oil plumbing with a scavenge pump.

I still haven't pushed this car into the Cal Sag, although I have considered it a few times. I ran into one minor setback, but I'm moving forward again. I had to cut out and redo the mid plate mounting tabs because I didn't like the driveline angle when I put the transmission in for mock up.

Changing the angle of the engine moved the turbos slightly and changed the angle of the down pipes a little bit. The driver's side down pipe is fine. I'll have to modify the passenger side downpipe a little bit, but shouldn't be much of an issue.

Last night I started making the driver's side exhaust. I'm just running the exhaust straight back into a pair of Borla XR1s in the stock location and dumping it before the rear axle. As much as I would like to run tailpipes, there's no way I can fit 3.5" over axle pipes with the anti roll bar I have. For the sake of time and ease of assembly/disassembly, I'm not going to make an X or H pipe. If it sounds like crap, I can later figure out a way to merge the mid pipes. From the little research I've done there's no benefit to a crossover mid pipe after twin turbos, other than it may improve sound.

How often do you plan to take the car to the track ? Or is this more street ?
As often as I can, but realistically it will get to the track 3-5 times per year. I'll be able to drive it on the street a little bit.

I mainly just like to build stuff. I took on this twin turbo project because I wanted to improve my fabrication skills and get more comfortable with TIG welding. I could have stuck with nitrous as a power adder, but I wanted to learn something new.

You might be surprised how streetable it is, I have driven my '67 about 14 hours on the street since last fall. I figure that's gotta be 500 miles.
That was another big reason why I chose a twin turbo setup. I went with a somewhat mild hydraulic roller cam and kept compression around 9.4:1 so I can run 93 octane on low boost if I want to cruise on the street. I'd love to be able to cruise in it on nice days.

Hot side and exhaust fab is complete. Time to start fully welding everything. I'm glad to be done buying stainless steel for now. The weekly orders to Stainless Bros were really nickel and diming me.

I'm really happy how this came out for my first time doing any major fab work and it's been rewarding seeing my welding skills improve.
