V6 Crankshaft Info

Yes you will need to get it balanced and likely machined before putting on your buickVR motor.

You sure I'll have to get it balanced? Everyone I've spoke to reckons they are already balanced and just get it machined...mmmm How much does this ballanceing cost? Machined (which I was only going to do) is $40.

Cheers.

Ecotec and buicks have the same cranks but they are balanced differently. They're already nalanced but to suit ecotec not earlier buicks. To get it mirrored balanced (with your old flexplate) would cost about as much as machining any engine specialist will be albe to do it no worries.

Big Thanks for clearing that up mate. I'll ring around and see if I can get it mirror balanced, not just a machined...

I believe the oil pump drive is different between the two crankshafts ?

Well they are the same dimensions / sizing. But lets not forget the manaul crank has the dowel pins & the holes drilled to suit.

So basically a manual crank will drop straight into a engine thats running a auto transmission.

Where as earlier ecotec engines that had a auto trans don't have the dowel pin holes drilled. So if you want to put a manual box behind one of these auto cranks you will need to have it drilled for the dowels or run the flywheel without the dowels.

Some have had no problems doing this where as other have had bolts come loose or snap. Your choice.
