More ARP stuff

Got more ARP fasteners when I was in the US. Picture below of shiny ARP 300 series stainless steel stud kit for exhaust/turbo manifold. The stud kit is rated to 170K psi tensile strength. Supplied nut is 12-point.

Next is the ARP Pro Series bolt kit to secure flywheel to crankshaft. The QG18 crank/flywheel uses 6 bolts. Picture below of ARP vs stock.

ARP offer two styles of flywheel bolts: High Performance and Pro Series. Both are forged from aerospace grade alloy and heat treated prior to thread rolling and machining. Both feature an exclusive 12-point head design and larger than stock shank diameter for increased strength and improved flywheel register. The High Performance Series is rated at 180K psi tensile strength while the premium grade Pro Series, originally developed for Nascar competition has a 200K psi rating.

The Slowtra is very close to going in for its "oil change" job. Expect a dearth of articles then unless Toby and Chew Soon can take regular yummy pixs of the progress.
