I have three VR4 heads here varying from stock to all after market parts.
I also have stock VR4 pistons and rods in excellent condition
Wiseco 85.5mm pistons (8.5:1) in excellent condition on Eagle rods that have had a spun bearing - may be able to clean the journal up.
VR4 block in really good condition - it had 137,000 kms on it before blowing a head gasket - the entire bottom end looks great.
VR4 crank in excellent condition
2.3 litre stroker crank that has had a spun bearing - a machine shop would be able to clean it up to suit oversized bearings. It was balanced, stress relieved and knife-edged not back.
Excedy sports organic clutch on VR4 flywheel in very good condition
Plenty of other 4G63/VR4 stuff here too,
PM me if you're keen on anything - I need the room in the shed.
I have photos of everything but hosting them is an issue now with Photobucket so I'm happy to email or message them to you.
Located in Sale, Vic.
