Suggestion · Original poster
Is there any reason anyone can think of not to use the 3.4 CAT on the 3.6 exhaust.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 3.6 engine (2003 996 Targa - nope no warranty) blew recently with complete engine failure with a crack in the block around 12 inches long. Apparently not the IM Shaft as originally thought.
Anyway new engine going in and while installing the new engine we discovered the coolant washed out during the blow up destroyed the cat on the passenger side.
I can�t find a used 3.6 cat (new around $1800) but found a used 3.4 cat from a friend. Is there any reason anyone can think of not to use the 3.4 CAT on the 3.6 exhaust.
They should be interchangeable. I have one for sale however from my 3.6 if you feel more comfortable....

Nope not a thing hit, a well maintained engine and car, I'll be posting the video shortly and you can see it just going into a corner , a slow one at that, My hand is already out, the clutch is in as I hoped to coast to the pits and then boom, there she goes.
i can get you the part number in a couple hours. Mileage is about 8k miles. It was basically new and looks it. I only want $200 plus shipping from 28214.
Currently uploading in HD, lol, I don't want any laughing or giggling at my young lady letting go alright... she has a few problems and we've taken care of them...
Leaving some on the table on most of your track-outs, but lookin good there Sean. You must have had some good instructors.
Seriously, that was a pretty good looking lap right up until... Look forward to seeing you back out there in a couple of weeks.
I was actually taking it easy as I was testing out the cheap (compared to the rest) SUMITOMO tires. I'd been playing with the pressures to see if i could get them to act as good as the goodyear F1s I had on previously and if they actually made a decent track tire.
On the street they are actually damn good, dry or wet and very low road noise, but the track you just don't feel safe going into some of the high speed corners such as 7 and 12. Actually coming out of 7 on entry around 95-100 just doesn't feel good on them. And around 135 on the straight back end was bouncing a bit.
None of that matters now, the SUMITOMOs are strictly road tires now, The Nitto's are mounted and ready for the next track session in 2 weeks. New engine, 2 year unlimited mile warranty, I'm going to drive it like I stole it...... safe though,
wow... glad you are ok. Sorry about the failure... as for the cats, I dont trust the OEM's, they seem to die fairly quick. Maybe aftermarket is the way to go.
Picked the young lady up this morning from North Houston Porsche. A big shout to David Moore and Rodger Gay for all their help. Below are some picks the close up was taken on the iphone so it's not the clearest but it's where the crack starts and then goes all the way back of the engine.
You'll also see a bunch of metal bits which they think is one of the valves or whats left of it maybe i was reving too much, I remember sitting around 6K rpm a couple of corners before, it redlines over 7 though, but hey all water under the bridge just now.
I got under the car to take a look, boy it all looks nice and new.
