[Matt]

So awesome!!!!

[Hypnotic]

Very nice build!

[REXXYY]

Cheers guys will be getting a flex tune done in the next few weeks to see how she goes on e85 

 

I have a brand new GTX35r with tial .82 V-band rear housing, Turbosmart 40mm compgate, etc to go on but due to funds at the moment that will have to wait till later in the year now. 

 

Here is how the engine bay currently sits. The battery is now in the boot and the battery tray will be getting cut out and that side of the bay sand blasted and resprayed. My mate Anthony at Dahtone Racing is going to fabricate a custom radiator overflow tank, custom washer tank and custom fuse box cover which will all be powder coated gloss black to match the piping and catch can. 

 

[Niko]

Yikes.

 

Tidy bay.

 

Like that shade of red.

Cheers I bought it off a mate already done. It has been honed/ported on the inside which is supposed to help increase torque or something. 

 

I was going to relocate the fuse box to under the dash and hide all the wiring etc and have it all smoothed on the passenger side but i was getting prices of $1800 just to relocate the fuse box. So custom tanks it is lol

If you like smooth bodywork, my Dad has his MY05's rear doors shaved, looks great if you haven't done that already.

Na I havent thought of that actually. It is a daily though and most of the time its driven is preschool runs so having rear door handles is probably easier lol. 

[Niko]

Haha yeah, also affects your insurance as well. Keen to see some full body shots. Also love that the interior has been kept factory, especially the Head unit.

[REXXYY]

Head unit is a 6 stacker from an 06 Forester 😊
I don't really have any good exterior shots but I'll put some up tonight they are on the laptop.

[Jimbo]

That is the most attractive short block I have ever laid eyes on! I have an old RS short in the garage to make a coffee table out of, how would I get it that clean!!?


Would love to see this thing thrown down the 1/4!

[Morgan]

Wow!

Deshele does some fantastic work. Your car is no exception. Also keen to see some full car shots.

Hey mate Leigh gets the blocks bead blasted, acid dipped then paints them with that aluminium looking colour it is.
