Arais 14:1 custom pistons
Eagle LS rods
Eagle Stroker Crank (95mm)
Darton Sleeves (bored to 86 mm)

B16a head:
Port and polished by Alaniz
Skunk 2 valvetrain with Stage 3 Cams
milled .025s
JG Edelbrock intake manifold
Ericks Racing 72 mm throttle body
Custom Race headers
440 RC injectors

So............ All I need is some spark plugs. I now that I need some NGK 7 or 8
heat range but I can't find a part number. PLEASE HELP!!!!!

 

anybody?

 

You should use NGK R - 7113 - 8 or 9 , it's the Best Spark Plug for NA for Race ONLY but it is VERY EXPENSIVE .

God Bless U

 

you are going to need larger than 440cc injectors
