Build a turbo bobber in 30 days
« on: April 20, 2015, 09:49:40 AM »
Hey everyone! My name is Teddy and I'm currently in the process of starting up a small shop. This bike build and two other car builds are the catalyst for the shop. 

The bike in question is a Honda cb650 of an unknown year. We haven't checked the serial numbers but after a quick google search it appears to be an early 80's. The bike is owned by my roommate but all the welding/fab will be done in house at Factory Fab.



The plan behind the build is to finish it before may 15th which for those that aren't into the vw/Audi/BMW scene is the weekend of one of the largest east coast car meets, Southern Wothersee. The bike and another car that we built will be premiering there. If the title hasn't already given it away the bike is getting a tdo4 from Wrx.



It's pretty overkill for a 650 but late spool times is what we're after and if it is way to  big, we've got a vf11 (smaller OEM Subaru turbo) waiting to go on which uses the same exhaust housing flange. If you're interested in any of the other builds check out our instagram @factoryfabrication.

Very cool, watching with interest!  I wish you the very best with the new shop.  The world needs successful and sustainable independents doing cool stuff!!!

All of my turbo knowledge is theoretical, but I suspect that with a turbo that can support 220+ whp on the 2-valve engine that makes 50whp unboosted your spool times are gonna be somewhere between late and never.  Even the VF11 can flow more than you're ever gonna get through the SOHC heads, I believe.  I would definitely recommend starting with the smaller turbo.

There's nothing more expensive than a free bike...
FWIW, I'm not a shill for Race Tech - I've just got a thing for good suspension and the RTCE's are the most cost-effective mod for these old damping rod front ends.
