Type 4 question, Size?
 

I need some help, I have three differant type 4 engines, in various states of dismantle, and I'm trying to figure out the size they are :confused: they all have the heads off (at least). I remember hearing about valve sizes. I'm not sure where to look for the info. I'd appreciate any help on this subject.

Thanks,

If the heads are off, then measuring the bore size would be the quickest method of finding the size- assuming they haven't had any unusual rebuilds.

Then check out Tunas site with the displacement table.

Stock from the factory the 1700 and 1800 came with a 66mm crank and the 2L a 71mm crank. Bore size 90mm, 93mm and 94mm respectively.

Otherwise check the case numbers and compare to this table on Tunas site

thank you
 

Thanks for the links, that's EXACTLY what I needed. Using the info in the link you gave me. I bought a complete running 2.0L Bus engine for $40, :cool: and two Type 4 heads for $5 each, 1 is a 1.8L and the other is a 2.0L.

Thanks again for the link.
