Fuel System

Being an turbo charged engine, I decided wisley that the fueling was one of the most  important parts of the system. Hunting around for a EFi fuel pump is not as easy as it seems, and just buying one off the shelf can be costly. For example a Bosch Motorsport pump will cost around $600Au second hand !, VL Turbo Commodore pumps approx $150 second hand - Specs 1.8L per min @ 3bar/45 psi
Not  willing to burn that much money for a pump I looked for another alternative. I went to a local Jap wrecker and asked what they had, the guy showed me what looked like a truck pump, it was this huge rubber encased thing that didnt look too new. He didnt know what it was or what it came out of so I parted with $90Au and went home to test it. I took off al the unsightly rubber covers and found a brand spanking new Bosch pump, shiny, shiny.
After testing it and finding that it flowed 3Lt per minute, I was shocked and I rang around trying to find what pressure it was pumping out, I rang Bosch themselves and found that it came out of a BMW M3. Specs are 3Bar/45psi @ 3Lt per minute. 12v
Rec retail about $390.

hahahahhahaa. The wrecker would have shot himself had I told him. Deluxe !

Dennis the man - moulie ,welded up a 1.5Lt surge tank for me with 4 outlets. Pefect job, just like a bought one. Thanks to you kdounous.
Next stop was to get a low pressure pump that would feed it enough fuel to have the bosch pump constantly fed, EFi pumps dont lke to suck fuel they prefer a small amount of pressure to be behind them, therefore a Holley Blue fuel pump would do the trick. Supplying 70G Per hour @ 9psi, I beleive it is more than up to the task. The Holley pump is set to run at 14psi.

Fuel lines were a problem, the original lines actually run inside the car, they are sealed off from the outside world by a hard plastic cover, they are only small in diametre, so in the bin they went. Dennis once again came to the rescue  with two 3M 1/2 inch bundy tube fuel lines. I think they are made out of copper/stainless combo steel. Worst job of all is bending the lines up to match the underside of the car, and a pipe bender was another expensive and unusable option anyway. We just used a paint tin and patience. The lines run up over the rear suspension and come out into the rectangle hole in the boot. From here I can attach them to the surge tank.

Gearbox setup

Current Gearbox is the Thema Gearbox. This obviously will be modified, that bloody M word. I have been speaking to Bits Of Italy boss Philip Buggee in regards to building a LSD for this gearbox, he currently does LSD's for Beta Coupe GB's but as yet hasnt done one for a Thema GB. We will see how this goes. The fun part will be the gear linkage setup. The Thema GB is nothing like the Beta.
I will also have to install a Hydraulic clutch, but thats a minor job. A new 4 puck clutch with a 2400lb pressure plate will be on the cards soon.
The gearlinkage is not standard as I have found out. The small rod linkage that connects the shifter to the swivel arm on the subframe assembly, has metal bushes as opposed to the fragile rubber ones. Why I dont know but by looking at the other linkage setup I have it looks like a great idea. It has two circlip style pins holding the ball inside the cup.
