So time for another update.
My entry has been accepted for WTAC 2012! Time for the work to begin! Well... continue. The next phase of development is happening now
I had to replace the water and oil lines that go to the turbo. The water lines were speed flow rubber braided lines but the rubber was actually melting through the braid. They have now been replaced with teflon braided lines and fittings so shouldn't stop it. The oil feed line had been crushed between the turbo and the strut tower. I was shocked when I saw it but turbo seems fine. Noticed it early enough to avoid causing too much damage. It's now secured so it won't happen again.
I've started stripping more out of the car for weight reduction too. So far I reckon about 25kg. The heater box alone was 9kg. All remaining sound deadening and carpet is going too. Roof lining, centre console and anything else that isn't really needed.
The old half cage is gone to make way for a full 6 point cage in the next month or so.
