Thanks mate
Now that I've read the thread I think I'll sit on the side line and maybe learn something.
Side note: Went down a path for an aftermarket plenum for my 32.
Purpose was to reduce temps, improve airflow to rear cylinder/s, and a minimal response/power benefit.
I'd worked pretty much everything else on the car and this was the last thing I did performance wise.
Hey Noel, your on the track regularly aren't you? Did you go aftermarket or do a cut/shut on existing ?
We both have different Skylines to Abdul so I have no real clue about a 31 Cefi. So suppose I shouldn't be commenting.
Personally I wouldn't attempt a cut n shut myself.
