Cast manifold for better reliability (welded ones kept cracking and was a pita), manifold moves the position of the turbo, so need to redo the exhaust as well as intake plumbings. Couldn't get a 2.75" pipe in Perth, so had to go 3", which decreases the MAF sensitivity and will be to meter more airflow. While I am at it, might as well try a different turbo... and since I am going to do a retune, I want to be able to start monitoring in real time whats happening, so added some gauges... and to add further reliability, I'm adding in a J&S knock safeguard piggyback so as soon as it detects the start of any knocking, the piggyback will automatically retard the timing... and there we go... $$$$.....
Could have saved myself $500 by buying the SS braided lines from eBay... still regretting buying from our local crazily priced merchant thinking at worst it would be twice the price... turned out to be 5 times the price... *rant off*... :-)
