It's been a long time since I have been on this forum and it looks like things here have slowed down quite a bit unfortunately.
I haven't put much work into the car for a few years now and am finally hoping to finish up the build and get things tuned. it has just been sitting on a lift in my garage in running but incomplete condition since having a kid and not having any time for the car. I also got a new daily that I have been modding, so it also pushed the G to the extreme back burner.
I figured it's time to start ramping back up and getting back into it. My goal is to get the car into decent tuned and driving condition by this year, then finish final bodywork and paint next year.

Quite a bit of mods to the suspension etc as well.
Before finishing the fuel system.. Just curious if anyone is using the Radium FHST returnless system? Not sure if that would currently be a better option or not.
Definitely hoping to get it fully running and tuned soon. Would like to push it to the limits of pump gas and daily it that way for a while. Then one day maybe throw E85 or 110 in it and try to max it out on a dyno at least once.
Did some work on the daily for now. Also I missed the step about moving/bending the fuel line away from the turbo so I got that done so I can at least safely run the G now without risk of fire.
Car will hopefully be driving soon. Got a tune prepaid for and lined up once its fully put back together again. I am hoping it will put down some decent numbers.
Car is coming together - Ive had it for a few weeks now -

Intercooler & charge pipes -
Intercoolers are pretty easy to install on these chassis especially if you can splice them into the crash beam. Its a great mounting option and still leaves room for an oil cooler and power steering cooler. Easy enough after some basic measurements and a round with the bandsaw. OEM crashbar aluminum welds ‘good enough’ not necessarily the cleanest but will take heat well and as long as you get enough amps to fill & bridge between the bracket and the beam it turns out well.
Charge pipes were a challenge … the 3” from the intercooler to the throttle body was easy - done in two sections, added the BOV flange and a port for the waste gates/boost control solenoid. The driver side was pretty easy too - just how the turbo was clocked and couplers were previously installed it was simply dive-bombing the sway bar and wrapping around to the inlet of the IC. The passenger side was incredibly difficult and cumbersome. It much come straight up out of the turbo, past the coolant pipe and the front rail then immediately come forward, wrap around the power steering reservoir, down the frame rail, around the radiator shroud and into the intercooler. Was difficult to envision but the fabrication process went relatively quick. Used a single coupler to connect two runs of pipe.
Fueling - got the 1600cc injectors installed and the radium fuel rails - a neat design that mounts to the manifold bolts and not the OEM rail bolts. Plumbing was easy enough to route from the feed, to the rails, and back to the fuel pressure regulator. I’ve always liked radium products and they didnt disappoint. I fabricated 1/2” and 3/8” stainless steel lines that run under the car.
I used gates rubber hose to connect between the tank and the stainless steel lines and the stainless steel lines and the fuel rail.
