Top end rebuild price?
Hello,
I've been getting some pretty wild prices and advice on rebuilding the top end due to broken head studs.
One of three shops in Portland,OR. said... no rebuild, but, just to fix the broken studs and anything else that may be damaged $5-8K.
The other Porsche/Audi/BMW repair shop said for the studs and top end rebuild should be about $4K.
The other facility is a high performance race shop focusing on Porsche (I think they do a lot of out of state work), named Rothsport. He has many options, the cheapest being "below $5k". Replace studs...check everything out, do the valves, guides, but he said it is usually best to keep the old rings if they are still OK?????
Big bucks to update the cylinders and heads, parts alone are more than $3k just for the cylinders!! Ouch.
Any advice? Help.

Try not to fall into the trap of not doing the update. I mentioned machining your own cylinders and heads to save money. Plus, it worked for Porsche with the factory 935's, they were pushing alot of boost. If you just replace your broken studs, most likely you will have a leaking cylinder to head surface down the road, because the surfaces have not been trued. Try to approach the shops to have them guarantee that your cylinders won't leak after there fix a year down the road.

I responded to your "Broken studs" post. Most of the '91 engines came with the factory updated heads (see that other post for details).
As far as your prices go, they sound high to me (at least for my area, which is Washington DC and is by no means a cheap area). When I was checking out the 964 over a year ago I decided to get quotes on what the cylinder head job would cost and it varied considerably, but most skilled independent shops were talking about $3500 for a re-machining and MAYBE as high as $6000 for the complete, Porsche certified cylinder update. There's a world of difference between a major top end rebuild and having to have the studs replaced. Before going the top end rebuild route, find out if you have the updated engine, and then check out your valves and anything else that may go wrong with your car (might as well have a shop fix it if it's going bad while the engine is out).
Good Luck,
Bill Wagner
