You best bet for HP if money is no object is
www.aircooledtechnologies.com; get the PowerStroke, which was designed
specifically for Buses and Vanagon for folks who want/need more
towing/pulling power. You can read all about it there.
Yours is currently a 71 (stroke) by 94 (bore). The PowereStroke takes it
to 78 x 94, with snazzy heads, a decent cam, and (gag a maggot) big
carburetors; which gives you what you want in the Vanagon, more torque
without a bunch of head heat. If you have the $$$, and don't care about
your fuel mileage or passing emissions inspections, call Jake and order
one, they range from $3,900-5,000, but be advised, he won't talk about
dealing with fuel injection or emissions; carbs and pipes only.
Boston Engine Exchange also does smart things with Type 4 motors and
have earned a reputation for turning out rock solid daily-driver motors.
No popping wheelies, but the motor will still be turning at 125k, which
some others may not be.
After having rebuild dozens of these myself, I can tell you there is no
'inexpensive' rebuild, and RELIABLE performance improvements
(particularly for pushing that big freakin' brick) are few and far
between. Do NOT go to larger bore (BTDT, bad idea). I'm running 96mm and
wish I wasn't, the head temps are super chancy. I use my van almost
exclusively in the winter until I can afford to build a stroked motor
for it. Whatever you do, don't even think of the huge bores (like 101,
103, etc.) unless you like having a 10k-15k motor. These kits are a bad
idea with a capitol B.
In a perfect world, a 76mm counterweighted crank, 94mm KB pistons in OEM
jugs, 34 x 44 914 2.0 heads, WebCam hydraulic camshaft and lifters,
ratio rockers, CD ignition, 96 plate oil cooler with fan, and CIS-E
(Lambda) injection would be extremely reliable, would probably pass
inspection with flying colors, and would also yield somewhere in the
120-160 range for HP and torque. A very noticeable increase.
Do all this yourself, and it will be in the $3,500-$4,000 range.
For reference, I just did rings and valves (motor goes back in tomorrow)
and it was $1,600, w/ me spinning the wrenches. Thanks Bus Depot,
AirCooled.net, T.Hoff Machine Shop, and FAT Performance for being there.

Subject: 81 Westy Dead Engine
Greetings everyone,
Well I have taken the plunge and bought a pretty clean 81 Westy with a
dead
engine. Minor bumps and rust here and there, but will be fun to clean up
and
use. Looking at options whether to rebuild or do an engine conversion ?
1)Is there any performance upgrades that you can do to the stock 2.0 L ?
Has
any one on the list done any ?
2)I have been reading some stuff on the Porsche engine conversion, any
thoughts on this one ? And what would be the most reasonable Porsche
engine
to transplant ?
Thanks in advance for your input everyone!
