Yesterday I finally got my used dual-port/dual-relieve AS41 VW engine case delivered back from Brothers Machine Shop in California. I dealt with Renato and his brother, they were great. They did a good job and even took the time to answer all my questions over the phone about what to do with the case.
I'm not sure what size engine I'm going to build yet. This case has 92mm cylinder bores but Renato recommended that I build a 2276cc with 94mm cylinder/heads (shaving out the head sleeves) and an 82mm stroker crankshaft, he said that people easily get bored of smaller engines. I'm not sure If I'll do that though. I think I'll be wanting to drive this engine 3-4 days a week, and sometimes for long distances. Some of the guys from Miami V-Dubs mentioned that they usually drive up north to VW shows a few times a year. So maybe I'll stick with something around 1800cc - 1900cc, I'll have to do a little more research, and consult with Bruce from McNab Foreign Car to see what he recommends.
For now the case will sit in the box for a while until I decide what to do with it and save up some money to get the rest of the parts.
If you are reading this and know about VW engines, drop me a comment, let me know what size engine you think I should build.
This is what I had done to the case:
- Check the case for cracks/warping
- Alignbore Engine Case
- Cut Thrust
- Full Flow (Drill and Tap Engine Case)
- Stroker Clearance Engine Case to 86mm Crank
- Weld Plate Behind Cylinder #3
- Sleeve Lifter Bores
- Remove the Oil Pressure Relieve Valve
- Chemical/oven Clean
