If it was then VW probably wouldn't have gone with a full flow filter and the additional costs in working this in. You must admit a full flow filter is far better than a screen. > >4.

These engines aren't as rare as people think and they have a pretty good after-market -- bigger than any stock T3! > Yes, it can be done, and made to work but the > costs will be approximately double when comparing stock > 1600cc rebuild vs 2000cc. Please clarify 1600cc rebuild vs 2000cc. Stock T3 vs. stock T4?

Okay, that type of talk takes you out of the Dark Side category! :) > They had Typ 4 engines already in 1966 and > never gave it to the Typ 3 Well, that's because the T4 was a different car :) Looking at VW's current selection of cars shows that they look different but under the skin they're very similar, if not the same in many respects. ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
