Just a couple of questions: -
1) Mandrel bent intake - who would be able to make these for me in perth?
Waste of money really look good but my vinidex drain pipe works the same and made no difference.
2) Fuel pressure regulator - my car runs pretty rich especially at idle (Cam+Chip) - could I buy an adjustable fuel pressure reg to pull some fuel out of the mix? Opinions/Advice appreciated. This is a good thought. You need to get it adjusted on a dyno ( usually lower pressure works better) Go to Auto One about $90 with guage I think. The Malapasi stuff is good but exxy!
3) Leads - I have a pretty big cam with chip and all the rest, would getting thicker leads make a difference to spark etc also what about spark plugs. Is there anything else you can do to get a better burn?
Good new stock leads are fine. Maybe a set of (JMM Dev spark plugs) Autolite 985's for fun. I didn't think they really worked but was surprised they worked at all as they were very different.
4) Head shave - How much can I take off my AU head safely i've been told you can take 0.20thou off easily enough which will up the compression quite a lot.
Compression on the AU head is high enough unless you've ported it and removed a lot. Compression isn't that bad on the AU I6. waste of money again.
Hope some of you's can help, just need to know before I spend the money
