I have a 74 2 Liter with a tired [but good] original FI and the compression is down a bit on at least 2 of the 4. I am surprised at how well it runs even with the various leaks.

I am planning to do my very first rebuild [not complete mind you] and want to start out replacing the pistons w/Mahle flat tops, new push rod tubes and seals, rebuilt heads w/all new valves, springs, etc. I am sending out the heads locally but will supply the parts. In addition I am going to renew the seals and gaskets on the tranny and go thru the FI systems seals, etc. Last but not least I have a pair of like new SS Heat Exchangers from a 1.7 and plan to convert from the 2.0 since they are getting ragged.

Is this a lame approach???

If you're going with new pistons you might consider going with 96mm KB pistons available form www.aircooled.net. They will yeild a larger displacement (2056cc) and is a popluar combination for a little more power. You will have to get your cylinders honed, but you would probably have to do that anyways with new pistons.

Any engine machine work you have done can be done at RimcoVW in santa ana, CA. You would have to ship your stuff to them, but its no problem for them. www.rimcovw.com

Another area of concern is cams and lifters. Lifters definatly wear down, so you will almost definatly need to replace those. Depending on your budget there are different ways to go. I'll let some real engine guys chime in now. Good luck!

By the way, make the first thing on your shopping list Jake Raby's Type 4 rebuild video. Its probably the most important tool and it will answer most of your questions. www.aircooledtechnology.com for more info.
