A bit of background first, I'm building a mid-engined kit car using a 1992 Toyota/Lexus 1UZ-FE (a 4l V8), due to space limitations I'm losing the twin distributors and going to Coil-On-Plugs (COP).
It's come to the time I'm thinking about making up some wiring and I have a dilemma with the temperature ratings of the wiring, common thinwall is rated to 105C (with excursions to 120C), Connectors are rated to 125C. The wiring for the COPs will be enclosed in the grove in the cam cover with a plate over the top to hold the COPs in place.
Now I'm thinking that while 105C *should* be fine it could get mighty hot in that enclosed space and I'd be better off with higher rated wiring (eg 125C-150C).
The questions I have are:
1) Am I over thinking this, being an idiot and 105C will be fine?
2) If not will silicon wiring (rated to 150C-200C) be fine?
3) If not any suggestions for the best wiring to get and where from (in small amounts not 100m reels)?
