Re: One Hella Busted VW 411 Needs Fixing + Engine Tins ASAP - Austin, TX
Don't obsess on what the internet tells you is right or wrong. You just need 2 pistons that match 2 bores. The closer you can get to compression the better, but it's not essential. Same for weight and even for bore diameter. I speak from experience.
Thanks to this forum, I learned that tungsten is a great material to fill wrist pins with to get pistons to match in weight when they are grossly disparate.https://forums.24hoursoflemons.com/viewtopic.php?id=6191
I also have run a motor for multiple races with 3 different bore sizes and compression ratio pistons (8.8, 9.4 and about 11:1 in the same 4cyl motor).
Just make it Vroom. Fix it right later.
Besides, it'll be a better story.
If someone from SoCal has a motor they want me to bring out to Stef to put in on Sat night at the track, I'll have a mostly empty trunk on the way out there.
Ooh. You're not taking a tow vehicle down there, are you? I desperately need to find a tow for this whole shebang to the race as well.
