I heard the I5 and the V10 have a lot in common. I've heard you can use the V10 head but I didn't look deep enough to confirm. It handles great and the suspension looks to be less complex than my BMW. I noticed on the back of the motor it's a little wet, I thought maybe a weeping rear main but I dug further and it looks like the vacuum pump gasket is kaput. Watched a couple videos and it seems easy. Seems I'll need a vag-com cable too.
