RB30 Compression for turboing

[mudnut]

I misread the post #16 and thought your vehicle was duel fuel.

Advancing the cam one tooth to open the valves earlier is supposed to give the engine a bit more low down grunt, but you loose some top end power.

I have read that Holden and Nissan used different cam timing for the Commodore and Skyline but I don't know if there is any truth in that. If it is, then there should be no engine damage if the ignition timing is set correctly so there is no detonation.

Do I need to run snorkel to airbox or ok to connect straight to air cleaner?

Post a picture of your set up, so we can get an idea of the easiest way to do it.

Well that didnt work. Basically, I have stainless piping that runs from aircleaner 60 mm then 90 degree bend then increases 100mm where it meets inner guard. Is yours turbo?

Don't know why they're upside down.

You need to have a section of flexible hose between the body and the engine.

Cut a section from the end that attaches to the air filter and fit a corrugated rubber hose similar to the original.

Personally, I would use the original dust spinner. After having driven on dusty roads, especially in convoy, I found the air filter was still fairly clean and the rubber cap was nearly full of dust.
