95mm pistons

[Passatman]

Found these on ebay although i can't seem to find any info on the piston pin size. I am starting to really love the waterboxer as from what i read here and can see piston and sleeve won't be too much of an issue with these engines, bearings should, are the 2.1 ltr waterboxer engine main bearing still readily accessible.

WBX should have pistons with the combustion chamer in the piston dome.
since there are very little cc at the heads.

I was looking for pistons too and found some possibilities:

Buick 3.8 pistons and chrysler 3.8 pistons The KB website has more specs and pics
But this is what I really want to do:

Smallblock ford stroker pistons

AA PEFORMANCE 101.6 cylinders (4inch)
Fins removed they are less than I could find plain sleeves for.
Some welding and machining will need to be done on the heads

Yes fastback i know that the combustion chamber i in the piston. I was just looking around when i found a post here and started t look at some options.

Could the 101 fit in the standard waterboxer cylinder spigot also i measured the thickness of the stock liner at the top and it was 6.3mm the type 4 stock liner is 5.5mm. If you can get a liner that is at least 6.0mm in thickness at the top then you should be o.k.

Some welding "MAY" be required. my thought is to mill notches at the stud holes the back fill them down about .300" thick with weld into the stud holes. Then using an eccentric sleeve coming from the "valvecover side" of the head - redrill them to the exactly the diameter as the threads of the head studs with the eccentric AWAY from the cylinders, then machine the cylinder spigots, this will give slightly more seating area for the cylinders. Yes, it will break into the stud area like 94s on an aircooled so there will be no o-rings!
Another thought would be to use offset inserts and chromoly 8mm type 1 headstuds using the method above would push the studs out even further gaining cylinder seating area and possibly use of O-rings (I am not convinced they are really needed)
My thought is to use copper headgaskets and cut a small groove in the cylinder to minimize movement. Also a groove can be put on the face of the cylinder for an o-ring if there's enough material.
Cylinder deck will have to be precise. I run NO headgaskets in my turbo Vanagon now just O-rings with no problems.
