Whats a build thread without photo updates... Boring !! .... Image


Next installment
Around September 2010 i bought my Coupe and this came of the road again for more work.

The next modification was the fitment of a Custom remote shifter mechanism ... As you can see the standard gemini gearstick comes out of the tunnel on a large angle quite a way forward compared to most cars
Image

This adaptor bolts to the quadrant box moving the shifter down the tunnel to a more freindly position ,whilst also shortening the distance between shifts ..
Image

Only install pic i took with half the bracket installed
Image

Here it is all fitted up with .. The Gemini Automatic Transmission Center console fits perfectly. Image
Image

Next i fitted my Base model TE / japspec Grille and Round headlight Combo, still dont know if i like it , so i have kept my other set of headlights and grille.. I also have a a ZZ/Z and a ZZ/R front spoiler to test fit.
Image

Image

I had some Custom white faced gauge backgrounds made up , i had these installed by an Instrument shop in balcatta as i heard many stories of them being ruined and uncalibrated when the needles were removed at home. They also scraped the white paint off my needles so they were clear and then painted them in a special orange paint .

Before
Image
After ..
Image

Big problem with my design .The black letters and incrememnts do not let the light thru . I had them remade with outlined numbers/increments to hopefully fix the problem. (yet to fit) Image
Image

Basically from here is the start of my Turbo Conversion .. Originally i had a Ballbearing '01 WRX Turbo adapted to a Piazza Cast Turbo manifold i was going to use , but them i bought Petes Coupe and decided to Buy a larger Turbo for the sedan and aimed for at least 200hp at the wheels WITHOUT forged pistons or rods . At this stage my engine was only 40,000ks old and collected some parts.

Garret GT2871 rated@440hp and GemRacing exhaust manifold
Image

GemRacing Stainless Steel Dump pipe
Image

Also got 2 pairs of braided brake hoses for both cars Piazza Front brakes.
Image

My spare room . 440cc injectors , Custom Plenum , New Diesel Gem Radiator , billet camshaft , 20mm adjustable rear swaybar
Image
Got my race seats re-upholstered
Image

Test fitting intercooler . 530x230x69 It Fits !!
Image

It took a lot of playing to get the right combo of fan sizes and order to be able to fit this with air conditioning. It was never going to fit with my aluminum radiator , so this was sold and i had a larger gemini diesel radiator reconditioned and bought some thinnner thermo fans. Image
Image

Started on the motor , My 2L motor has a 1.6L cylinder head fitted for higher compression , I wanted to swap this for a 2L head to keep the comp a tad lower
Image

Removed the head at home then took my car to Dads work and pulled the motor to fit a Sump with an Turbo oil return
Image

Happily we discovered the motor had been balanced in the previous rebuild.
Image

I also fit a Double row timing chain and sprocket kit
Image

After some grinding and filing work i got my Plenum fitted to my lower Rodeo Runners . These were then powder coated by Dads mate as a favour.
Image

I needed to buy some bolts as the studs fouled under the plenum , also painted my VL throttle body .. About now i realized i had forgot to get a accelerator cable bracket welded onto my plenum Image
Image

Around this time Feb 2011 , i killed my Coupes motor , and this project got put to the side for a little while , Bad news is next update may be a while away but it is going be Killer

Thanks guys . this grille is only fitted to the very basic poverty pack TE Geminis in Australia , Quite hard to find nowadays as they were the ugly duckling back then and break around the lights very easily ..It was a lot more common on the jap gems.
