just doing some research for a customer.

he's looking for more power out his EB XR8 5 speed


he said he has a 70mm TB just wonder if the is a 70mm MAF that will bolt on?

and what cam do you guys recomend? and any computer mods if needed?

If he is running a 70mm throttle body - a Pro-M 70mm, Bullet 75mm or C&L73mm can be used. I would try to stay between 5-10mm larger on the air flow meter so the throttle body is the intake manifold restriction - not the flow meter.
For cams, the Crane 2030 and 2031 are well know for making power - and is certainly tried and tested amongst us Australians. The Trick flow stage 1 cam isn't a bad item and the Competition cams XE266HR and XE274HR are pretty good as well.

will these cams run with the standard ECU?

Yeah they are all designed for the stock EEC although some people have problems. The EB/ED EECs adapt pretty well I have found.
