well... contact suncoast for yourself and see... the sale is on boxster cayman engines.... and 3.6 early 997 engines.... but *not* the 3.4 for the 996...

Anything can be done with enough $$$$$

if I had a 99 engine that blew... at $6,100 I'd go the Suncoast way and pay for the conversion cost... out the door you'd pay no more than $12K installed... with a warranty....

...almost as if Porsche is *punishing* the 996 devotee community with this 3.4L replacement engine pricing debacle. Obviously they monitor ALL Rennlist activity - but this is absurd. I'm still convinced that Porsche realized they made a serious design and engineering foh pah on the 996 powerplant and to help the owner community out with it would only serve to ingrain the fact that they 'acknowledge' the issue. That's a human-natural reaction. Especially considering that Porsche is going to be taken over by VW. And acknowledgement of a crap **s engine design at this point lessens their engineering overmatch with VW and weakens their already shaky bargaining position. Sad, sad indeed. But gents - thems the facts according to Mar - you heard it here first.

The problem with that argument is that the issues really aren't fixed with the 997 motor are they? I don't know what all of the specific differences are, and I'm curious what it really takes to put a 997 motor into a 3.6 996. The 3.4 non-egas etc...I think it's a lot further removed.

BTW -- a friend told me today that the stealership wants $15k to replace the motor in his 2002 996. At that point, personally, I'd rather go standalone ECU and 997 motor. I know that will work! Will loose the ABS and PSM though....

Anyway, what a crappy market to sell anything! 15k for a new motor and I'm having trouble selling my 40k mile 3.6 for $6500! People should be jumping all over it but the bottom line is people aren't buying stuff now.

You should be able to install a 3.6 or 3.8 from a 997 into a 996 if you use the correct DME. There is an experienced DIYer who has done several conversions on Boxsters including a 3.8 into a Boxster. Google "tholyoak" and you will come up with several hits. He has done extensive write-ups on the issues you will face and covers the DME issues as well. IIRC he uses all factory parts and doesn't use piggyback systems.

It's worth a look considering the price of a 3.6 Vs a 3.4.

I think the IMS bearing was updated to a two row assembly in the MY '06 if that is a concern of yours.

c70Pete,

I wonder if Porsche will still warranty a motor if it's installed in model other than what it was originally specified for? It would be worth checking out first if the warranty is a driving factor in ones decision making process.

yes of course... when I asked Pfaff they told me they would need to plug into the engine to diagnose... so if you were doing a 3.6 conversion you would be using a 3.6 ECU and wiring harness... so it would essentially be a 3.6 car... the question is what do they plug into and if you did the conversion would it be seen by the diagnostic tool as a 3.6 car...

Todds911

The other 3.6 conversions on the forum used the same 3.4 DME, but remapped. They used the old mechanical throttle body too (not Egas). And something for the VarioCam. But this was for a 996 3.6 conversion.

It sounds like you are saying the 997 3.6's need the 997 DME. What about the eGas issue, etc?

Either way, it sounds like the 996 engine issues are evolving/progressing. Maybe one day all us 996'ers will have 3.8's in 'em?!!!

Tbred911

you'll need a new fuel sender unit... new e-gas pedals... new wiring harness... center console adapter (if you want A.C) 996 ECU (not 997 cause the ecu still has to control 996 components)

Hopefully, this is an easy question:

What about swapping a 1999 3.4L C2 (drive by cable) into my "dead" 1999 C4 (egas)?
Is that straightforward? ...same DME, harness? ...other remapping or connections?

Thanks!

Tbred911

I think that can be done... there is something that needs to be done with the e-gas connection... has to be removed... I'm not sure but I remember a mechanic saying that that engine would work... they would have to take your non-gas components from your dead 3.4 and transfer them to the new engine...

Tippy

I dont know a 100% but Id say just use the throttle body from the non-egas motor and put it on the new, egas motor.

Marlon

I have a strong-running 1999 3.4L reman with 3K miles on it that I will sell you for $23.5K It just happens to have a perfect C4Tip wrapped around it tho But you can take the engine and toss the 'car'...

I'm waiting for some guys to finally figure out how to install the new corvette LS9 engine in a 99 996. Then, I'll have the baddest car around. Watch out.
