A 3.2 can be modified to 3.4, 3.5, 3.6, 3.7 or 3.8. The cylinders are not bored, rather, the jugs and pistons are replaced. Other modifications are required including tot he crank when getting to the larger displacements.

Oh I see. I see... Yes, I would pass on it too. Too bad, Id love something like that with a good rebuild.

Have you noticed that MM advertises in Panorama monthly....thats disappointing.

This is a nice car that drives very well. This car would do wonders on the track, not all rebuilds done by MM are a failure and I'm in no way affiliated with the outfit. Please do not post my home address and phone number.

"not all rebuilds done by MM are a failure"

How can you defend these guys? You are either ignorant or worse.

[mjshira]

hmmm one post... sure you are not

I'm a big fan of the 'German Process' which involves crushing the piston ring lands to reduce clearances to like new.

Neato.

It
just
gets
uglier -

So you are not what? I did not appreciate my name and address being posted.......that's it.

[Craig 930 RS]

Glad to see you are 'not affiliated with this outfit'
Come on........you are the OWNER of the car ~~

[ndavis951]

You guys crack me up anyone in Connecticut want a test drive, trust me you will not be dissappointed. And for the record the car is all there

[thomschoon]

It cant be that bad of a rebuild, after all he got the "BIG BATTERY" option for $109.95

Noah,

Sorry, I thought about that a lot. I figured it was published
in a national publication; I did an appropriate quoted excerpt
for critical review and was posted as an image which is difficult
to search. I should have erased the personal info. Right call
Noah. I’ll re-post the text only.

This was published on page 84 of the February, 2006 issue of
Porsche Panorama. On one hand if something is published, it
is fair for critical review. On the other hand, we need to
respect people’s privacy.

I was tempted to post the MM advertisement from the Feb
Pano issue but didn’t in deference to Wayne’s policy. That
adv could stand some scrutiny in light of everything else.


This ‘89 911 would make a nice daily for me and I’m interested.
I would have to assume the worst about the installed engine
based on all the posts on the various 911 bbs’ and some
face-to-face discussions with MM vic…. err, customers. I’m
not the least hesitant about swapping engines back & forth.
Having a good OE engine and then disassembling the MM
engine for inspection doesn’t bother me. Over the past 35+
years most of my Porsches have had multiple engines available
and many swapped regularly. I had nine 587/3 engines
for 904-017, 904-055 and 718-055. That is 8% of the total
production of the engines!


Perhaps these discussions can persuade some to change their
ways and make amends for past indiscrete practices. Hope
springs eternal.

Best,
Grady

As posted before....Pano is a whore.....they'll take money from anyone.

I'm not jumping on the MM bashwagon, since I have never used any of their products.

I am curious as to how the 3.6L displacement was achieved. Since this is your car, I assume that you know what you the build entailed and what you paid for.

Taking a 3.2L to 3.6L & beyond requires the following (I am going to skip 3.4L & 3.5L short-stroke & long-stroke because it is apparently not relevant in this case)

100mm cylinders w/ pistons that are specially machined and are used with a 964 crank will make 3.6L with a 3.2L case. This conversion would use the stock connecting rods if one wanted. I didn't find any reference to a crank being purchased, perhaps I missed it?

102mm cylinders w/ pistons can be used with the stock 3.2L crank which makes for a 3.7L motor. Aftermarket rods such as Carillo or Pauter would need to be used with this conversion.

This is assuming Mahle components of course, which would form the basis for a stellar rebuild. A large displacement motor such as this would need twin-plugging and an extra cooler (in addition to the engine & aux. cooler in the fenderwell) to survive long-term in a street environment.

I think other people have asked before, but what are the internal specs to arrive at 3.6L? Not bashing, just curious since I can't divulge the info from the invoice.

I wish you good luck with the sale, I don't think the guy needs to bashed for trying to sell his car. I would speculate his car is nicer than many others here on this board.

No affiliation to anyone. They must be doing something right (or won the lottery) if they have been around as long as they have.

Ralph

EDIT: "Popular" bore & stroke combo's for Mahle piston/cylinder sets. Some combo's originally developed & built by Andial.

95mm x 74.4mm = stock 3.2L

98mm x 74.4mm = 3.4L

98mm x 76.4mm = 3.5L long-stroke

100mm x 74.4mm = 3.5L short-stroke

100mm x 76.4mm = 3.6L

102mm x 74.4mm = 3.7L

I think it's already been stated a few times in previos posts that ndavis951 did not pay MM for this work - he bought the car with the work already done.

I, for one, think he's done a fine job in the eBay listing - the MM stigma will make it a bit harder to sell, but at least all (ok, most) of the cards are on the table. Props for that.

I would like to know the reason he is selling it however - as stated in the ad, the car sounds fine and a hoot to drive. I would love to own a 300+hp 'carburetored' beast. Why let it go?

Yep - and I see where the engine has been bumped to 3.6 but the crank has been cleaned and micropolished... Huh?

I think that is your reason for recourse. Tough to get to 3.6 without changing the crank - invoice says crank cleaned and micropolished. So - how did they get to 3.6l?

and if they didn;t = fraud. Sell me something that is not true.

I wouldn't want my name and address on an invoice for MM either.

[Grady Clay]

Ralph,

I couldn’t agree more. I share your curiosity.

Could you edit your post showing the bore/stroke for each? Many need that info when considering these conversions. Much of this is in Bruce Anderson’s Porsche 911 Performance Handbook 2nd Ed. available from our host. There are also crankshaft-to-case issues.

I also agree, this seems to be a very nice ’89 911 Carrera. Has it had a PPI?

Best,
Grady

[shamrockcustoms]

Well as much as everyone loves to get all amped up..Davis is not the owner of this car.. The owner buys and sells cars. thats how he makes a living. He sells quality cars and in no way is out to screw anyone..Yes it is unfortunete that MM did the engine work but this in no way reflects on the seller.. Just my 2 cents

Thanks Jay well said. Jay what color is your S4
