83 911SC Engine Rebuild
Hello everyone,
My vision is to have a drivable street car and also one I can track.
The Heads, crank, and cams are coming back from rebuild this week.
Here is what I am considering and would appreciate guidance if this planning is flawed or if you have a better idea.
CURRENT SITUATION:
The case is a late model 3.0l and seems fine.
The crank had # 5 rod journal under spec, oil starved. The machineshop was able to modify the rod so that I can still use a standard rod bearing on the crank and the rod is so marked.
The rods have been resized
The cams were pitted and repaired.
The heads have been rebuilt and flycut. The cam has been assembled into the rebuilt heads.
All this for $3100.00 good or bad I don't know but it is money spent and a bit more than budgeted.
I had planned to reuse my Alucil P&Cs but #1 has pitting on it. I could find a replacement P&C but then I still have the Alucils and concern that it will smoke.
I plan to keep the CIS
NEXT STEPS and request for comments:
I could just reuse the Alucils and replace the pitted cylinder. Does that make sense?
I am also considering 98M 9:5 JE Pistons and 3.2L replated cylinders. This is about $3,000.00. Does the investment increase power accordingly or should I just stay with the Alucils?
Would installing carrera sport cams $500.00 with the JE even though I had the original cam repaired improve performance enough to make the investment?
I had originally planned to add the SSIs, but from reading posts, understand that they have dimishing returns at the 3.0l engine range.
Instead I am now thinking of using a MK or Fabspeed cat bypass premuffler setup for track days. Would this equal the performance of the SSI's?
I have also read about a Supertrapp system for a muffler replacement using differing combinations of discs for tourque and sound. Has anyone ever heard of this or used it?
One other thought is to convert to a 3.6 95. Any opinions??
Please let me know your opinions.
Thanks,
Roadster49
