Boiler Inspecto, I haven't got an engine case to "Test" it on. If the 3 bolt bearing carrier is the same as the earlier style engine then the bolt circle is the same and the same dimensions still apply.
It would be nice to "Test it out" on a scrap block so that a customer would have the knowledge and "peace of mind" that it works. I personally don't need to do that as the machining is just the same as if i was doing it on a Horizontal Boring Mill or even a regular Vertical Miling machine big enough to set the cases on. The only difference is the way that the tooling is attached to the back of the engine case, the machining of the bore uses the same skill as what i've done for years.
Here's a little background about me.
Born 1955 in Manchester England;
15 yrs old i started my 5 year machinist apprenticeship.
Emigrated to the U.S.A. at 25 in 1980.
Worked for Southern California Edison as a Nuclear Maintenance Machinist from April 1981 till September 1st 2014. Removed and overhauled pumps, motors, valves, gearboxes, steam turbines, The Reactor Coolant Pump mechanical seals stand 30" tall x 12" dia. and the replacement pieces in the seal cost $250,000 alone. Ran Lathes , grinders, miling machines, Vertical boring mills, Horizontal Boring mills, In Place Machining; which is exactly what i'd be doing to a Porsche engine case.
Sounds like i'm "banging my own drum" but i am a highly skilled professional thats been at it for 45 years and when it comes down to designing and making the machine needed to perform this work it's just "what i do best".

All i really need is someone who wants it done. I welcome anyone who would like to talk to me about this. Call me at (760) 468-6312 cell or (760) 731-2972 home or email me at
