I have the following set up on my 1990 R32 GTR

Hks 2540 turbos

Apexi Power FC

Split Fire Coil Packs

Sard Fuel Pressure Reg

700cc Injectors

Big Fuel Pump

Standard AFM’s & Air Box

I attached a photo of 1 of my Iridium Plugs

no im serious, coppers conducts electricty better than the iridium compounds.

but obviously lasts not nearly as long

coppers are cheaper, work just as good.

if ur afta a quality plug for a high boost application get ngk R5671A-8. was recommended by a reputable tuning shop in brisbane i wont mention names of shops. were like 5 or 6 bucks a plugs a lil bit more expensive then the standard heat range plugs but worth every penny if they work properly

8's are fairly cold for regular skylines. Try R5672A-7. They don't have an extended electrode but work well in the skyline when an 8 is too cold. Have used them in a few cars now without any adverse effects.
