Review of Porsche Classic Factory Restoration Atlanta

I am considering buying a 911SC, 996, or a 968. I'm sure it'll need some work; has anyone had experience with the Atlanta-based Porsche restoration center?

Engine detonation

 

im building up a nice 83 SC. The engine is stock except for PMO 40s, headers, centrifugal only distributor with a curve that fits within Porsche recommendations for earlier engines. MSD ignition.

I can’t seem to rid it of detonation at low speeds below 3000. I have to feather it in or it sounds like a bucket of bolts. I’m running Sunoco highest octane and have backed starting timing as far as 5ATDC. It makes a difference but still rattles if I get on it even a little.

1982 SC Cam tensioner upgrade

I have a pristine 1982 911 SC with 45k miles that I put less than 1 k miles of Sunday street use a year.  The valves have never been adjusted I have had  a slight oil leak from the valve covers for many years and I am considering having the valves adjusted when I have the valve cover gaskets replaced. Do I really need to upgrade the cam tensioners?  I hate fixing things that are not broken and spend an additional $3000 plus.  However I understand it could cause catastrophic engine failure.  And if so which kit would be the best one to use.

3.0 - 3.2 rebuild Mockup Timing

Hello Chris

It's been a long time since I last emailed you in which I've lost your email address.

Well I'm finally back at it, in mockup and I'm setting the timing .....

I have #1 at Z1 1.26mm (964 cam grind) and attempting to time #4. I turn from Z1 where #1 is opening for about 270 degrees where # 1 is almost closed and #4 has just opened to 1.26mm for the intake valve stroke in overlapping TDC valve clearance with the 1st. I'm on the notch approximately 260 degrees on the crank, approximately 100 degress prior to Z1.

Upper Rebuild Only

Model: 911S, Year:1977, Mileage:100k, Type of use:Street use only
My 77 911 2.7 is right at 100k. Always runs well and cool. 11 blade fan and tensioner updates. Driven gently. No smoke, etc...I fear a head stud or two may have pulled. Money is an issue. What is risk/reward for proper rebuilding of top end only and letter lower end alone? Thanks.

runaway cold idle

Model: 911 SC, Year:1981, Mileage:143,00, Type of use:Street use only
I have the issue covered in a posting dated 11.20.2008. The reply says the 'auxillary regulator' but does not mention a fix and I don't see a match in further checking the postings. What's the fix? FYI this is a ROW car so there's no CAT if that makes a difference.Thanks,MM Koon
