Hi,
As I'm doing some upgrades to my 88 Z31 I was wondering what the best choice would be regarding spark plugs. Especially the heat range.
I know stock is 6 but with increased boost I probably need to go up to 7 or 8. Just don't know what would be the best guess to start off with and not having to worry about detonation from my plugs but still having a good running car.
I'll do a little write-up on my build soon but these are the basic upgrades I'm doing.
- Holset HX35 Turbo
- 550cc Rx7 injectors
- FMIC
- 3" exhaust
- Autronic ECU.
Im looking to run about 20 - 22 PSI of boost on 102 octane pump gas (would like to run 98 oct but I'm starting off with 102 to be safe)
Would like to hear from the experience you guys have.
Thanks!
