Someone asked me to add engine sizes such as 1641/1776/1835/etc. to the Dictionary on the site, including bore, stroke, crankshaft size, piston size, and so on.

I realized I don't actually know what the common engine sizes, especially these days where I know a lot of people "stroker" engines.

So feel free to post a list of the ones you know.

Thank you.

To kick it off, I know a few:
1500 = 83 x 69 = 1493 cc
1600 = 85.5 x 69 = 1585 cc
1641 = 87 x 69 = 1641cc
1679 = 88 x 69 =1679cc

1776 = 69x90.5
1835 = 69x92
1904 = 74x90.5
2110 = 82x90.5
2180 = 82x92

Would this help?

Im sure you must have a few charts like that huh, :lol: These are like the most common nowadays. Here anyway....

2276 = 82 x 94
2332 = 84 x 94

Back in the day was all the ones Craigman listed.

The chart is great but note that 76mm is missing and is also a popular crank. Now the 78mm cranks are bastards and confusing. You can get a 78mm, 78.4mm or 78.8mm crank from different manufactures.

Thanks for the chart, I think I will just link to this thread rather than add some huge list.

Keep any other combos coming...

there are also non vw pistons that fit just fine,some you can bore/hone a used up set of cylinders for a new life. and some are v8 sets so the cost per piston comes down, I recently got mahle motorsports 2, v8 sets that came from roush/yates racing for thier gtp program, bore size for 1 set 3.702 the other size 3.705. High pins,short coated pins,light setup,strong steup.and there are many more applications out there that fit with little work. DSS makes some nice XS forged pistons up in st louis ( I think thats where there at) and the prices are great. just hone your dead 90.5 cylinders(corectly,or bore&hone,they have many over sizes) as far as engine size thats up to you and your wallet.when building a hp vw engine that has possiably 1 or 2 vw parts in it why stick with the old out dated expensive not realy ever intended for hp usage pistons,and the je stuff is just too high for no reason.I was a je dealer years agoabout $700 for a 4.5"&bigger bore full v8 set, not I see 4 vw pistons for more than that.why???not for me.

If I might add the Type 4/914 in my Thing. 78.4 X 103 = 2616cc. Hard to keep the 103's sealed though.

the problem with the chart is it includes a bunch of wack combos that never should be built, and is misleading to people that don't know any better.

"Popular combos" should be relatively easy to build by some guy on his kitchen table, where he doesn't need a machine shop to do a bunch of stuff.

Some Type I combos, stock and up to 84 mm stroke:

77 x 64 = 1,192 cc = 1200 "40 horse"
83 x 64 = 1,385 cc = 40 horse "big bore"

77 x 69 = 1,285 cc = 1300
83 x 69 = 1,493 cc = 1500
85.5 x 69 = 1,585 cc = 1600

87 x 69 = 1,641 cc
88 x 69 = 1,679 cc
90.5 x 69 = 1,775 cc (commonly called "1776" even though it is 1775.4 cc)
92 x 69 = 1,835 cc
94 x 69 = 1,915 cc (sometimes called "1914")

85.5 x 74 = 1,699 cc
87 x 74 = 1,760 cc
88 x 74 = 1,800 cc
90.5 x 74 = 1,904 cc
92 x 74 = 1,967 cc
94 x 74 = 2,054 cc

85.5 x 76 = 1,745 cc
87 x 76 = 1,807 cc
88 x 76 = 1,849 cc
90.5 x 76 = 1,956 cc
92 x 76 = 2,020 cc
94 x 76 = 2,110 cc

85.5 x 78.4 = 1,801 cc (never actually seen this, but possible given availability of 85.5 mm B pistons)
90.5 x 78.4 = 2,017 cc
92 x 78.4 = 2,085 cc
94 x 78.4 = 2,176 cc

85.5 x 82 = 1,883 cc
90.5 x 82 = 2,110 cc
92 x 82 = 2,180 cc
94 x 82 = 2,275 cc

94 x 84 = 2,332 cc

I want to build a 94 x 64 for 1777 with a 2" header, 51mm IDA's and a 31mm oil pump!

Tue Jun 03, 2014 11:31 pm

Do it, I'd like to see it, too. Odd strokes used to be more common when VWs were used in a lot of motorsports - it is easier to "trim" the stroke size to fit within a CC limit for a class than to find the appropriate pistons and cylinders. There are true 78mm stroke cranks out there, but it is very hard to find out before you buy them which they are.

How about someone draw up a chart with all the possible combos of known strokes and bores, we can "poke a hole" for the impossible sizes, highlight bolt together sizes that members have built, and a different highlight for the "bastard sizes" that have actually been built, and leave the "possible bastards, but no-one has tried yet" with a default background?

The Dictionary says 1200 is 36hp and I believe it.

The formula for figuring engine size is simple.

piston size X piston size X stroke X .0031416 (PI/1000)

94 x 94 x 69 x .0031416 = 1915.38 which is rounded off to a 1915cc engine.

Mon Jun 16, 2014 10:11 pm

yeah we hear 1915 or 1914, close enough.

the popular 90.5x82 is 2110
IMO 94x76 is 2109

They are almost the same size, but that way we don't get em mixed up. the 2019 isn't as common but it's a good size too

Actually, both the "36 horse" and "40 horse" were 1,192 cc. The reason I have quotes around the names is because those figures refer to the SAE gross hp numbers. In Europe they were rated by DIN hp and were actually 30 hp and 34 hp, respectively, for the 36 and 40 horse engines.

I was trying to figure out which engine had bigger displacement the 1800 type 1 or the 1800 type 4. Found this displacement chart below? What was the factory bore on the 1800 type 4?

Not sure what you are asking. There was no type 1 1800 from the factory.

Dont forget about 80mm Cranks!
Im using an 80mm crank with 92mm TW to get 2127cc.
You could also use 90.5mm pistons for a 2054cc or 94mm pistons for a 2221cc.
