+1 Over sized engines just aren't needed when you have boost.
I wish I still had the pics of the one with the barrel valve billet throttle bodies. That one was nuts!
For the right price almost anything can be built.

found it. 
Sure you can.... These pics are lifted from another post.
1600cc motor
that is just beautiful!
Yeah I'm coming to realize that also. If your looking for dyno queen then the big motor turbos that are only going to last a few big pulls anyway are fine. If you are street riding I truly think its best to do 1363 max and leave it Gen1 crank and either tune it for E85 or run C16 if you are wanting to make big power. Just from talking to Richard at RCC he made it quite clear that any over stroked motor will change the angle of the rods therefore wearing the pistons faster etc....and all kinds of stuff. So if your interested in reliability then build a GEN 1 motor to the hilt and throw the boost at it. As far as 1397 Im sure it can be done okay you just are going to run into head gasket problem on big boost and you better have it done by someone you know that has actually been successful with 1397 turbos. Probaby the 13mm head studs should be on your list for sure
One way you could run Gen 2 Crank without issues of increased rod angles is to run gen 2 aftermarket rods and gen 2 turbo pistons. Therefore would keep stock angles. Seen couple bikes in the past with +2mm bore and stroke which works out to 1407cc very successful and reliable
Exactly, I think they are fine for smaller HP bikes but until you get some data and see them lasting on the 600+HP pulls them I'm not gonna be a test dummy

350 hp is pretty easy to get with a stage 2 setup. No need for a big bore motor on top of that. Good luck with what ever you choose.
