Re: rockers

Yes you can BUT it will come at a considerable cost due to needing new holes and other things needed!!!

Not really worth the hassle, trust me, I am in the middle of doing this at the moment. I have just talked to and seen slipper's car and it sounds amazing with the standard 1.6's in it.

Re: rockers

i'm talking a stock au II xr8, just unbolting the rollers & fitting the 1.7's to it to get a bit more lift.is there going to be any vavle to piston clearence problems? if not i should be able to just pull the 1.6's of and drop the 1.7's on, is that correct?

Re: rockers

but the problem is you can't just unbolt the 1.6's and put the 1.7's in. That is the problem

Re: rockers

Yellaterra makes a set of 1.7 ratio rockers for the AU, they made them for the T series fir tickford, they are a shaft mounted style, only thing to check is the piston-valve clearance. they are bolt down and do not need studs and guides

As redhotxr8 said, just get some Yella Terra ST-2027's and bolt them straight in. It will take about an hour or so. Piston to valve clearance shouldn't be a problem with the stock cam and stock valves.

You must be converting to stud mount rockers. but even then, they should still bolt in reasonably easy. You just have to add guide plates.
