just figered how to put a T1 aftermarket crank into a wasser case,
crank sizes are now endless!!!!!
you need,
a 2.1 wasser case with a 3 peice flywheel end barring
one set of barrings for a wbx
one set of barrings for a T1 case 1mm linebored and 1mm thurst
a ally ring custom made to down size the flywheel seal to T1 size
you use the T1 1mm line/thurst flywheel barring and the rest of the barrings are WBX and then assemble as you would a T1!
Or you can use a 1.9 case with an all T4 main brg. T1 crank, like I am doing.
the problem is this combo of crank is not "off the shelf"
now if you were going to build a T5oxyboxer you can also run a T1 crank "off the shelf" any size! and have the flexablity of flywheels and T1 clutchs!!! and bolt strait into a T1 gearbox!!!
there are only 2 types of case a
025 xxx xxx
and
025 xxx xxx B

Contact Rocky Jennings Enterprises… if you are serious about having it done.

sorry
My race engine is built with a 2.1L case and used a Bugpack flanged crank. This crank has Type 1 brgs, except the center main. Rocky makes a precision shim to take up the difference between the conventional Type 1 split thrust brg and the narrow saddle of the case. When I switched to a Scat crank with all Type 4 brgs, Rocky line bored the whole case to std. Type 4 size.

just trying to get people to think about going OXYboxer , people like to just "bolt together" "kit" style motors, if there isnt at "kit" avalible then it cant be done! they dont think like us."lets see if we can get this to work"

I agree. I ran a Scat case for one season while finishing the waterboxer case. I like the waterboxer case alot better! It's especially cool to be able to show someone the factory VW logo on the side of the case, just to prove it is a VW!
Steve Arndt, Hi I am making some split thrust brgs. with bug size to the crank & h2o boxer to the case but with all the other irons in the fire it could be a month or so before I start to split them. Thanks Rocky
Hi Peppe Could you go into detail on what the spacer is for and how it can help to put a t-1 crank into a 1.9 case. You can use off the shelf line bore bearing with .040 1mm o/s od. with a 1mm .040 o/s thrust to install a t-1 crank in a 2.1. I have a couple of test engines running my new (cnc made) thrust brg. to use a t-1 crank in a 1.9 case. Thanks Rocky

there you have it!
I haven't yet built an engine but from what I have read weren't some of the advantages of the oxyboxer the 5 bolt flange for the flywheel and bigger bearings (like the T4 bearings)?
So using a T1 crank means you step back down to the 8 doweled crank and smaller T1 bearings?
Out of interest can you fit a 76mm Wasser crank into a T1 case?
Hi Jeza The 5 bolt crank to the waterboxer cast iron flywheel is not as strong as the 8 dowel to steel bug flywheel. I have used a cutout 914 center & welded it to the 200mm steel bug flywheel & had 5 better grade bolts with 8mm dowel pins put in between each bolt for a much stronger set up. As for the 76mm crank into the bug case. You would need to line bore the thrust brg & cut the case for the larger 025 main seal. You could use a 210mm or a 215mm clutch & stock cast iron flywheel, that would be a step down from the 8 dowel crank & steel flywheel IMO. I use most of my engines for drag racing & cast iron flywheels are a no-no. Rocky
