Brakes and bleeding the clutch is all thats left for it to move/stop/maneuver under its own power.

Had an offer pop up that I can't refuse. A local turbo shop (Neukin Motor Development) want's to build an equal length tubular manifold turbo kit for the car at cost, so it looks like I'll be going through with that and this kit will be going up for sale. After that its just finalize some wiring, cooling system, paint, and tune.

Radiator is a Griffin, 27x16x3" twin pass.

Fans are to be determined, though they will be puller(s).

Once Beast (well, Neukin) gets the new kit done, we'll build the cooling system, as the turbochargers may end up moved back a couple inches from their current spot to get us a touch more clearance for the fan. The best case scenario is a Taurus fan, but it may be 2x slim fans with a small shroud.

Nick, get with me on the Neukin stuff, I'm curious what he's planning and would like to be around any possible time to see it as it goes together. He needs to jig this.

Also, I'm totally test fitting the new kit on the FC.

Once the car is back to full roller status I'm gonna trailer it over to his place. That way he has all the necessary goods to build the kit and we can still do some work on the car even while it's at his shop. I'll def have you come along so the 3 of us can colaborate on this. It's all still in the planning/design stages.

Digitalsolo knocked out the entire brake system this weekend. ABS delete, all new hand bent hard lines, Earls steel braided lines, Wilwood proportioning valve, Summit line lock, cleaned and painted all 4 calipers,rebuilt the rear calipers, Hawk HPS pads, and drilled and slotted rotors. Also took the intake off to install an LS1 steam crossover tube instead of the LS6 crossover tube (need to trim the bottom of the LS6 intake accordingly) as well as re route the -8 fuel return line to run under the passenger side of the car and move the fuel pressure regulator off the fuel rail and into the space where the ABS unit use to be.

2 weeks ago I picked up a set of 4 factory FD rims to go with the 2 stockers I already have (which have normal street tires on them), 2 of the rims came with brand new 10.5x26 Mickey Thompson ET Street Radials, the other 2 will be getting 11.5x28 M/T ET Streets. Along with those I picked up 2 rims for "skinnies" to run with the bias ply ET Streets. With those we were FINALLY able to put the car on all 4 for the first time with the motor in the car!

Still ironing out the plans/details on the new Neukin tubular stainless steel turbo kit.

Well the car has driven under it's own power now.

Next up is a slightly different turbo kit (tubular style) and finish cooling system, cold side and a few more details.

Nothing major. Haven't really worked on the car much. Swapped all the dash lights out to LEDs and changed the gauge cluster from a nasty amber color to pure white by removing the amber film on the back of the gauge faces, and also changed the climate control color from amber to red.

Decided to keep the turbo kit I have for simplicity and $$$. Going to add a section of braided stainless flex pipe on the drivers side for some wiggle room and also try and get more wastegate priority on that side as well by putting the WG at the 90* elbow right before the T4 flange.

Thinking about doing a double din touch screen "carputer" setup and running HP Tuners on it as well as all the normal functions of an in dash cd/dvd/nav screen, but we'll see.

Quick shitty cell phone pics. Gauges look perfect in person, not splotchy like in the single gauge picture, and the climate control is brighter in person as well.

Nothing to major to report yet. Sold the ET street radials on the FD rims and the car is now on 18" FR500s with 285 555r's in the rear and 255 HTRZ3's on the front. Got the flexpipe welded on the drivers side, and digitalsolo did all the modifying/fabricating to the radiator and that will be getting welded this week.

You really can't go wrong with a big single(88mm or bigger) or good sized twins (60mm+). Either way space is going to be tight. You're most definitely going to want to use the Samberg subframe though for extra down pipe clearance.
