Also made some more progress on it mechanically! Got the wiring harness nearly done and to working order and I've been tinkering on the turbo setup as well! Grabbed some DSM 450cc injectors from a friend for next to nothing and plan to use them to get the car up and running for break-in. Also grabbed a Kinugawa 20G compressor wheel and housing kit that I'll use for now while putting the parts for the 6262 together.

Thanks man! And another small part showed up today!

Last part I needed to finish up the oil return setup off the turbo! The rest of the fittings came with my 6262 kit I bought. Sucks they were a bit scratched up; but
they'll work. Now just waiting on the fittings for the oil feed to come in! It's equally as trick! Hopefully they'll show up this week. All I need after that is an o2
housing and I can torque the turbo permanently (for now lol) in place!

Made some progress on the oil feed line today when my fittings showed up! M10 1.25 to 4an fittings.

Sadly the fitting bottoms out in the head and required a bit of modification and upon further inspection the turbo fitting is a different size from the
cylinder head fitting!
Have to wait until tomorrow and I'll go figure out what size it actually is. I think at this point it's M12 1.25. Anyway, you
can go to about any auto parts store for the crush washers. They're brake line crush washers and easy to come by. Also, since the threading on the
fitting doesn't go all the way down and the crush washer floats around, I used spare HVAC orings from my oring kit to keep the washer from moving
around. Works perfect!

Finished product!

Almost ready to fire up! For the time being I've bypassed the turbo and just have my MAF hooked up on an intake pipe to the throttle body. Also went ahead
and blocked off the oil cooler since I haven't got a new one yet. I'll have one on the car before it sees any street use though. Already primed the oil system and
have good oil pressure! Just waiting on a few more fittings to arrive later this week and I'll put a few gallons of fuel in the tank and see if she starts! For now,
here's a pic of the fuel filter to rail line that I made compared to the stock line. Much better imo!

Here's the temporary fuel system:

Tossed a set of 450cc DSM injectors in with the stock fuel rail and used MAPerformance -6AN fuel rail fittings to get everything plumbed. The fuel return
comes from the afpr to the stock steel return on the stock rail and then makes it's way back to the stock return line under the car. Pretty clean setup for
just being temporary haha! The rail and injectors will be upgraded before any serious tuning takes place though.

Intercooler finally has a finalized installation! Thanks to rivnuts! Great setup! Part number from Fastenal is in the pic. The factory
bolt size is M10 1.25 which is unavailable sadly; but M10 1.50 is easy enough to get. Not 100% factory like I'd prefer; but close enough.
Here's how it turned out!

Rivnuts and part number:

For those who don't know, here's how they work:


We thread a bolt in with a good nut and a hollow nut. (Rusty nut is hollowed out with no threads) Hold the hollowed out nut and the bolt end
and tighten down the nut with good threads. It will pull the threads of the rivnut in and crush it around the sheetmetal. Holds tight! Just make
sure not to put too much torque on the bolt later and cause the rivnut to spin or you're screwed lol.
