Hi Chris,
Probably the first things to ask would be , who built it, what are the specs, how many k's does it have on it, any receipts for the work & the parts inside etc. I'm sure some of the other guys will have some more ideas for u.
I'm pressumming that it's a type 4 not type 1?
Where abouts are u located? What type of money are they asking for it? Its generally cheaper to buy a hot motor that someone else has built rather than purchasing all the bits yourself, but at the same time u don't want to be buying someone elses problem, what are the reasons they are selling it?
Hope this helps
regards
Jak
MOTOR
YES IT IS TYPE 4 IT IS A VW SHOP AND HE HAS A FEW MOTORS FOR SALE I JUST LIKE THE SOUND OF THIS ONE
U could ask around as to the Quality of the engines that the workshop builds, try to find customers that have his engines & see what they think? Get as much info & feedback as possible that u can get before u han over your hard earned dosh.
regards
Jak
