1996 Porsche 993 Carrera 2

They’re cheap for a reason as stated above. And even with a Hartech bells and whistles rebuild they’re STILL cheap. Win win.
I had four years of classic G Wagen ownership, with a very good friend swinging the spanner at mates rates, the bills were still horrendous - many multiples of a full on 996 engine rebuild... On a truck that has a name for incredible durability.
Just plan on an engine rebuild and half as much again for other bits and you’re sorted, bonus if the money stays in your wallet.

All IMH but The biggest problem is the 996 has, for the last ten years, been in the price range of those who want a 911 but don’t have anything left to keep it in shape.

Hi Mike, so sorry to hear your horrendous experience of engine failure and pleased you have shared this with us. It has the makings of a very interesting thread. Has a full fault diagnosis been carried out to ascertain the cause? You are in the best hands for that!!

@GMG I wouldn’t take the comments you are receiving too personally; even though you have been accused of pedalling lies and not being very helpful to the forum members, it is the message of failure that people don’t want to hear. You are in good company though, Baz got flamed when he reported a high number of engines that Hartech have opened up have signs of crankshaft journal wear at 100k miles and Ken has also been torched for some of his cautionary comments. They all have good experienced based information, but people didn’t want to read / believe this about their P&J so attack it and try to disprove it. We are on a 996 forum after all, you are hardly likely to get a good reception or balanced treatment.

Baz’s message was, ‘Guys, if you value your crankshaft, you should consider bearing replacement at 100k miles’ a stitch in time saves 9 etc! But that message wasn’t well received.

I thought @deMort nailed it with his comments which I and I’m sure other member value highly and Mr Corn’s balanced and experienced based comments.

IMS failure or bore scoring occurrence is relatively rare, but when it happens it hurts – it really hurts. That should be remembered. So in conclusion, you have as much right to post and share your experience as anybody, and your experienced based opinions may be considered extreme by some, but others may say that to do nothing, don’t worry, it won’t happen is equally extreme.

You do what you believe to be right!

Just my 2p!

Apologies Mike, your thread has probably been hijacked!!

...thanks bud and given we live in a democracy I am comfortable with speaking my mind and tbh don't really give a toss about the 'feedback' ...

What I know is that Hartech and every specialist I spoke with were rebuilding engines that had ***** themselves, that such occurrences aren't rare, that these failures are beyond the expected wear and tear for older performance cars and nothing can be done to mitigate or predict...

...and anyone stating that 100k miles cars are just run in are deluding themselves! The internals in the majority of opened engines will be significantly worn...my specialist commented on how 'good' my car was at 69k miles but I still required the replacement of everything from the tandem pumps,oil pumps,varicams etc etc ! Oh and he had three more M96 engines to fix!!

With reference to wear on my engine,bottom end was definately gone,but I did hear it starting to tingle,I know from race experience to stop immediatley but did'nt.That would have saved the crank & rod. Grant said the pistons were savagable.I just went the 3.7 route because you can't have enough torque or power.I am not gentle with any car I have and have a scrap box with destroyed engines from Alfa 16v flat 4's,inline factory race 2 litre twin cam. Cosworth turbo with cracked blocks.Rods through the side in Cooper S. All engines do go bang if you take to the limit. I did have the 996 round Millbrook one day for exercise.The bill for the engine is compareable with the engine I am having built for my Cosworth.I have been told not to take the 996 on track when done and enjoy it as a road car.Will update with progress.Mike.

Maybe a custom hard cut limiter next time?

That's not the issue, oil starvation is from what I read. Not uncommon with 996 on track.

Yes, that too, I was more thinking of the box of miscellaneous broken engines having a common theme

I would hope the 3.7 redesign addresses the oil starvation in long high g corners, I think I read hartech do something to counter that design flaw?

I have to say in my defence that most of my blown engines have been during races. The 996 was I am pretty sure oil surge. I haven't tracked it,just did one day at Millbrook wit CAT training.Mike.

I have been wondering what it would to dry-sump one of these.

You can dry sump them,just replace the bottom end with an early 991/964 bottom end.

Hah, simple.

I didn't realise that the 964/993/Mezger was staggered in the opposite direction to the M96/97. Underlines how different they are.

Nice choice choosing to upgrade to 3.7! What was the original fault in the end?

Hi,it had run a big end,buggered the rod & crank. We decided to let Hartech have the pleasure of rebuilding it. Steve is used to Cossie turbos & M3's.He will refit the engine etc & get it running. Will let you know how it goes. Mike.
