What plugs and belt size should I use for my new combo??

[Ystang99gt]

I have a 2.93 rr pulley at home with the billetflow aux 100mm idler. The question i had is what belt should i use for this combo and what plugs should i use?? Can i regap the stock plugs or should I just buy another set of plugs with a colder heat range?? Also should i buy the other two billetflow idlers??

Sorry about all the questions i just couldn;t find the answers by searching.

You can not use a Gatorback on the RR-Use Gates.
NGK/TRP6 @ .040 gap are OK plugs for 2.93.

I had ngk-tr6's on my supercharged gt combo and i didn't really like them much. I had better luck with the autolite 764's would that be a good plug for the 2.93 combo??

AR recommends TR6's to be gapped at .35.

Does anyone know what belt size i need?? If i remember correctly its a 74.5 but i want to mkae sure since i have the idler.

2.90/2.93/2.95 use a 74 inch belt. If you add an idler I believe you should use the 74.5 inch belt. As far as plugs go I use the stock plugs with the stock gap. I have a 3rd run YDH1. Dyno lines were very smooth with no signs of spark blowout. Stock plugs for me but most people go with aftermarket Denso's, NGK, Autolite's, etc.
