Update:
Further engine work, I detailed the rear and side engine frame removing the moulded bolt heads and replacing with after market ones as before. I also extended the rear anti-roll bar with metal rod to replicate the real car more...
This was then all attached to the engine block...
and so began the 12x wiring and tubing, starting with the ignition leads first...
I used MFH's tubing and wiring...
and with the first bank of ignition leads in place, I used some thicker hollow pieces of tubing as cable holders...
and with the fuel lines completed and the injection plate added along with heat protector from the exhausts, these needed to be scratch built as the kit version is far too thick...
Finally I replaced the exhaust end section with copper tubing for better realism...
