2.7 rebuild - thoughts on newbie's plan?
Greetings,
Just found this board and have been familiarizing myself with the surroundings. I searched the archives and found helpful information, and am searching for more before deciding what to do. I recently purchased a '76 911S targa knowing it needed engine work (leakdown test showed ring problems). Having read Wayne Dempsey's book and researched several web sites, I have a plan to rebuild the 2.7L motor. See what you think. Any personal experiences/insight/warnings are welcome.
First, some background info -
Car:
87K original miles, two owner, well cared for
Carrera chain tensioner, airbox relief valve installed
thermactors removed and stored in the Museum of the Failed
heads rebuilt to stock spec by Glen Krynock here in Richmond @ 68K
Me:
DIYer with two engine rebuilding experiences (Ford V8 and Triumph 4)
garage and tool supply adequate with special Porsche ones to be obtained
(anyone have any left over from their engine rebuild they want to sell?)
my plan:
I drop engine & remove everything down to the case (CIS, wiring, heads, cylinders/pistons, etc.)
Engine/machine shop (thinking of using RPM in Newington - anyone have other suggestions?) does the following:
remove head studs
split case
remove rods, crank
inspect all parts including heads, determine machining needs
install case savers and steel studs
reassemble case
install my new pistons/cylinders (from EBS with CR bump to 9.5:1)
complete long block assembly (heads, time cams, etc.)
I finish the job by reinstalling CIS, wiring, and engine in the car.
I'd appreciate any feedback, especially on a shop that would be willing to work with me on this. Thanks in advance.
