3.2 Engine Rebuild Kit

[cmcfaul]

I seem to recall when I rebuilt my 2.4 L (10+ years ago) I was able to buy a kit that included everything for a basic rebuild (rings, bearings, valves (guides, etc) gaskets, hardware, lubs and sealants. Does anyone sell something like that for a 3.2? (I did look).

Thanks,

EBS was advertising kits awhile ago...

Chris, how many miles on your engine? You may not need all those parts for a rebuild if your rings and bearings are in good condition. Unless you have case leaks or some other reason to split the case, I would leave it alone and only work on the top end of the engine. The bottom ends of the 3.0 and 3.2 engines are very durable in stock configuration.

I'm also working on my engine rebuild. Will share pics with everyone once I'm fully done

So far, in my limited experience, I've never come across an engine that didnt show some wear on rod bearings no matter how much the owner claimed it was good. Unless it has documented proof of a recent re-assembly, I'd always rebuild the bottom end. Just my opinion.

Our advice aligns with what Mike said above. It is not worth the risk of a few hours labor and some $$ on parts to not have to pull it apart again in the near future.....

That said, we are doing a 3.0 top end only right now for a client who is sure he does not want the case split.

Cheers

Years ago I started a top end rebuild due to high oil consumption related to worn valve guides on my 3.2. It had about 175k miles so, based on advice here, decided to just do complete rebuild. There was some wear on the crank bearings but all parts were in spectacular condition. I told pistons, cylinders, crank, cams etc. to a well respected Porsche shop here in the DFW area and they verified all still in spec. I guess I could have kept driving for quite a while but I'm glad I just did the whole thing. I enjoyed the process but it took WAY longer than I had "planned".

Bearing shells may show some "bedding in", but typically not worn IME, unless there was loss of oil pressure or contamination. Splitting the case causes additional expense and delays, usually needlessly.

If you are a professional shop, you want to go through the whole engine to warranty your rebuild, but a good DIYer doesn't need to do that.

That's why I asked the OP how many miles on the engine . Most of us will not put enough miles on an SC engine to wear out the bottom end. Valves and guides are usually what needs work at 150K+ miles.

Keep in mind the Bottom end is the same for 3.0L, 3.2L, 3.6L, 996 997 GT3, 996 997 Turbos and was originally designed for the 935 race cars, It is quite strong. That said its really not that much more work to split the case. Most of the work is cleaning up the case mating surfaces. The Int shaft bearings will always be shot so should be replaced.

Yeah, the IMS bearing is kinda strange. It has a very thin tin layer that wears off quickly, so it always looks like they are worn. But I haven't seen failures due to the IMS bearing shells, and it's not something people here have identified as a common problem. For sure, there are plenty of SC and 3.2 engines out there with 150Kmi, 200Kmi and more, that have never been split open, and that are running fine with their "worn out" factory original IMS bearings.

Back to the original question. I am also interested in finding a kit if their is one...

You might want to contact Henry Schmidt @ Supertec Performance, he will advise you on what you do and do not need and tailor a kit to your needs. His prices are quite reasonable and he is a wealth of knowledge if you need any advice or get yourself into a bind. His number is 760 728 3062.
