1970 911t 2.2
i am rebuilding an engine i recently purchased for my 1970 911T , 2.2 .
i had the casing line bored at Competition Engineering Inc in California which will require the installation of 1.0 mm shim to compensate for the casing surface machining. Also I had the Cylinder heads restored and machined to the tune of another 1.0 mm shim requirement. both machine shops indicated that it is not for certain that I need the relevant 1.0mm to compensate for their work but I might need to do few trial and error measurements with Play doh to figure out the exact total size of the required shims. I have purchased 0.25mm, 0.50mm and 1.0mm shims. can anyone tell me how many shims is acceptable or allowed? as i may need 1.75mm total. (it means one of each of the shims I bought. worst case scenario) Please help. Thanks |

Typically one shim is installed but 2 can be stacked. Not sure if anyone has ever tried 3. If 1.75mm was required to maintain deck height, I’d get some custom made.

Kamalea, I have the same issue with my '71T. My calculations indicate I need 1.5mm in shims. Do you mind sharing where you bought your shims?
Thanks. dho |
