As far as I know, you can build a completely streetable 94mm piston engine. 1914's are considered to be extremely reliable and are used as daily grinds. There's a couple guys on TS with street 2332s.
I brought up a 2110 as being my street motor during the GVP grand opening, and I was told to just go all the way to 2332...as it's completely feasible with the right cam and heads....
You can spend $5.5K from
www.calperformancelab.com and get a tranny and urethane mounts etc. He has an ad on the Samba, and there was a thread on TS with him, Chico and another guy talking about performance/reliability of thier motors....

I would consider them....as that's $6K for a 2L WITH tranny and everything INSTALLED.....
