I picked up this engine from a member of the "World" in Nashville and my son and I are going to attempt to rebuild it over the winter. We have a book, youtube, and this website and will document everything in this thread.
The first thing we had to do is get it small and light enough to get it down to the unfinished portion of my basement, so I put the boy (he's 4) to work pulling the heads off. (IMG:http://www.914world.com/bbs2/uploads_offsite/c5.staticflickr.com-14795-1477515217.1.jpg) Looks ok so far... Very hard to keep Blake from "organizing" all the nuts and bolts into a mixed pile. (IMG:http://www.914world.com/bbs2/uploads_offsite/c5.staticflickr.com-14795-1477515217.2.jpg) Success: (IMG:http://www.914world.com/bbs2/uploads_offsite/c3.staticflickr.com-14795-1477515218.3.jpg) More picture and questions to come. I have the cylinders and heads off and its ready to move, but still very heavy. Much thanks to walterolin for loaning us an engine stand, he even hand delivered it on a Sunday morning. Thanks again Walter! (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-14795-1477515219.4.jpg) |

Weren’t the dish top pistons used on the 73 1.7s? I know that the 71s had pop up pistons. I would put a set of 96mm p&cs in it and try to find a set of 1.8 heads with the bigger valves and better ports. Mill the step off of the sealing surface for compression. I used to mill the big boss of the small end of the rods to lighten them a bit. It will run great with the stock injection and be a fun engine.

Charlie If you are interested in this route, I have a set of 1.8 heads newly rebuilt by Brothers VW in Ontario CA, the heads have also had the spark plugs relocated to the 2.0 angle/position which is supposed to increase HP. PM me if interested and I can get you pics and receipts. |
