Put the car through its paces and everything performed flawlessly except the 2nd gear syncro.

Some pics from Bathurst Mount Panorama Circuit.

Had a good mix of cars and this little hatch surprised everybody.

CIC installed, 1m gear knob and boot.

Traction sorted on AD08r's fronts and trofeo rears.

Diabolical in the wet and unbelievable in the dry.

I had them laying around of another build in the shed but after a few heat cycles they came good.

New tyres would be ideal but this was always going to be built to use up all my parts I had laying about
left over from previous projects.

I basically cleaned out all my inventory and my better half is grateful as I finally have the garage, shed and backyard cleaned up
and she is not dodging all the storage boxes and parts everywhere.

This is how an e87 should be and is a hoot to drive and so much fun but if someone offers me enough money for this monster
I might let it go, its a 1m in a hatch body. See how things go.

New gearbox is on order and will be here in 6 to 8 weeks, 2nd gear syncro is stuffed but as most know bmw wont sell us the parts
so i have to buy a reco complete box to replace a 50 dollar part. :rage::rage::rage:

A log from the other day, slight overboostng issue, tune needs a little clean up but otherwise
things look really clean

If you check out and know how to read a log I got rid of a lot of restrictions that plague the RHD n54 design.

The WGDC is sitting at around 50% @21psi and a lot of room left, these turbos are not working hard at all and basically cruising along.

Went to the dragstrip last night, still waiting on the new gearbox as second gear syncro is shot.

I can't change from first to second but can take off in 2nd but it bogs bad so there is a lot of room for improvement.

But what surprised me with a full tank of e20 weighing in at 1521kg with the new wheels it managed 127mph on just 21psi.

Not to shabby for a little fat hatch.

Wind it up to 25psi and some proper slicks and it will do 130mph+ but no point if you cant drive it on the street, it already
lights up the rear tyres at 80mph on boost.

Wanted to find out how the tune was performing and if it needed some tickling, but no issues or problems.
