Video from uber-machinist John Edwards on Ogre's A12 race engine build-up: http://www.youtube.com/watch?v=g6Bibyic2nA (one can also go to youtube and search on: Stan's Datsun 1200 Race Engine
Almost ready to rock & roll in next season's vintage race series!

Ahh, I've seen a few of his videos before.

That simulator looks mighty useful. I'd love to have access to one of those.

The engine looks like it'll go pretty hard. Shame about the pulled thread though, thank goodness for timserts.

nice work.. the treads on the rocker pedestals are pretty common to come out..

This project is coming together, thanks to the likes of John at R&D and all of my Datto 1200 buds from around the globe! I've obtained parts & pieces from Australia, Japan, Taiwan, Thailand and all over the U.S. I've received useful info from dozens of 1200 enthusiasts everywhere. It is truly an international project for this little racecar. Thanks to all who have helped out!

Is that a nismo oil pump as well??

Nice

whats the go with the simtest? whats the engine conected to?

This engine is an old SCCA warhorse that was run for years in the San Francisco region. The engine features a ported GX head and a slew of NLA Nismo bits along with trick "modern" pieces like ARP head studs & rod bolts and B-Projects rocker arm collars. It is being resurrected for vintage racing, using a bit more moderate state of tune for longevity and reliability. (if 12.8:1 compression can be called "moderate")
The R&D SimTester has a variable speed electric motor connected to the flywheel end of the crankshaft, spinning the motor. An oil line connected to the inlet side of the oil pump pressure feeds clean oil to the engine. The tester allows a 'clean room' run in of the freshly built engine to bed all the assemblies in, check for oil leaks, find weak/stripped bolts, ascertain clearances of rotating bits at various speeds etc. without generating heat and racket. Since R&D doesn't have a dyno cell, the next step will be to drop the engine into the car and run it in using go juice. (which will be a bit further down the road since a lot of clean up and fabrication still needs to be done on the car proper)
