I would like a mobile version of the FMBC site, even if it meant losing ALL data and starting over.

Yes, it is uber important.

No, leave it as is please.

I am on the fence.

Ok. I'm always behind the ball. Nothing available at Paddy's wagon. Do they tolerate doubling up on sites? If so, anyone willing to double?

At some point in the future, I am planning to do a complete restoration on my 86 V-gon, and am thinking that it would be better to do everything all at once instead of a little bit at a time. If I do that, however, it would knock me out of a vehicle to camp in for quite a while. So- I'm thinking about buying another V-gon westy to camp in while my son and I do the restoration, and thus the question: Is there that much difference between the power and performance of an 86 or later V-gon with a 2.1L versus an 85 or earlier with a 1.9 L engine, both with a M/T? I've never even ridden in a 1.9L V-gon but I'm sure there are some Moonies who have owned both, and can enlighten me. Also, are there any other reasons to consider one vehicle over the other? Thanks in advance !!

Stock from the factory, I think there was 10 or 15 hp increase

The 2.1 vanagons have an ecu that controls fuel and spark

the 1.9 ecu only controls fuel

Below is from gowesty site


GoWesty Rebuilt Engines for 1983-1985 Vanagon
Looking for a replacement for your tired 1.9 liter (83-85) Vanagon? GoWesty offers a 2200cc and 2300cc replacement engine for the 83-85 Vanagon. In order to get to 2200cc's, we replace the 69mm stroke crankshaft that is originally fitted in the 1.9 liter engine with a 76mm stroke crankshaft that the 2.1 liter engines came with standard. Our 2.3 liter uses a specially machined crankshaft with a 78.65mm stroke. Then, instead of using the 1.9 liter pistons and heads, we use our own design 2.2 or 2.3 liter pistons and new cylinder heads of the later 2.1 liter design. The result is an engine that produces more power and efficiency than was ever offered from the factory. Our 2200 costs not much more money than what it would cost to properly rebuild a 1.9 liter engine back to stock. And, either displacement engine fits right in with no modifications required to the injection, fuel, cooling, or exhaust systems.

GoWesty Rebuilt Engines for 1986-1991 Vanagon
The original 86-91 2.1 waterboxer has a 76mm crankshaft stroke, and a 94mm piston diameter, and has an exact displacement of 2110cc. It has a compression ratio of approximately 8.6:1 and is rated at 90hp and 117 ft-lbs of torque. The standard GoWesty rebuilt engine uses the same, original 76mm crankshaft, but our own proprietary, US built, forged 96mm piston, yielding a displacement of 2200.4cc, and a compression ratio of 8.7:1. Our rebuilt engines are not just larger and with higher compression. We went through the expense and trouble to have the cylinder heads flow tested. Then, using that data, and for each particular bore, stroke, and compression ratio combination we offer, we have selected the best camshaft grind to optimize performance for that particular combination. All of our engines work fine with the standard original fuel injection system, and have had no problem passing the California tail pipe emissions tests. Our standard rebuild (2200cc) is OK to run on regular unleaded 87-octane fuel. ALL of our rebuilt engines produce more power and torque than the original design.

I have been told that the GoWesty 2.2 engines produce their extra torque and horsepower at the expense of long term durability. No facts to back this up - just from discussions at FMBC campouts. Has anyone else heard this?

They are more expensive and they offer a 48 month / 48,000 mile warranty

The engines with the higher compression require premium (higher octane) fuel. Thats the only thing I can see that would have an effect on durability.

Lower compression ratio motors usually seem to last longer.

As far as complexity goes, a waterboxer motor is still very similar in many respects to a bug motor and, therefore, relatively simple.

I'm hoping to install a VW turbodiesel when I do the restoration on my 86. What I'm wondering is if I buy a second Westy to camp in while doing the resto, is there enough difference between a 1.9 and 2.1L engine that I would notice that much difference? (I do like to camp alot in the NC mountains - would a 1.9 be slightly or noticeably slower pulling the uphill grades?)

the motors themselves are interchangable. The 1.9L is stronger and lasts longer than the 2.1L Rods were weaker on the 2.1L as such they tend to get thrown more. Boston Bob (RIP) would only use the 1.9L rods. I preferr the 1985 year personally. You can feel the HP difference between the 2. You can also get a ero computor for the 1.9L that will increase HP but at fuel mileage cost, Later md

There is a guy on the Samba called tencentlife who builds wbx motors, uses ARP fasteners, and has an excellent reputation on that site. He also makes a tuned exhaust, pretty slick looking. You can find him on the vanagon forum, or in the ads by doing a search for his name.

I have to look for it, but somone converted a wbx to an upright motor, put the radiator in the shroud, would bolt right up in a split or a bug.

FWIW, back in 99 the navy transfered me out to California. I flat towed my 65 Corvair with a 1984 Vanagon with a 1.9 and manual transmission on I-40 from Virginia Beach to Fresno, CA. Thats 3 mountain ranges. Also made weekend trips into the Sequoias up to 7500 feet regularly.

I liked the two-peice calipers on my 86 compared to my 85. The 86 would scoot around town and down highway. as for climbing hills and mtns I havnt noticed much of a difference between the two. Good luck!

Aswah has the go westy 2.2 and I know he wants to get rid of it soon. I will try and clue him in on this thread, and maybe get his mind off the fact that he is probably going to be a new daddy this week!
