You have several options:
1.  Stronger wasserboxer
2.  4 cyl. Rabbit engine
3.  Subaru engine

and probably others.  Check out Kennedy Engineering for the Subaru conversion.  There is a subaruvanagon list like this one, with input from convertors.

Is there a list somewhere of engines that can directly replace the 1.9<br>wasserboxer?  Or replace it with MINIMAL conversion?  I'd like to eventually<br>put a stronger engine in Beatrix, but would like to keep the cost under $3000.<br><br>Thanks,<br>David<br><br><br>--<br>David /NJ<br>85 Wolfsburg Westy "Beatrix"<br>90 Fox "Sampson"<br>
