How easy is it to drop a 997.2 motor in a 997.1?
I searched the web and didn't find anything. I'm actually kind of surprised this hasn't been discussed much before. Anyone know if a 997.2 engine (DFI) can be dropped in a 997.1 car relatively easy? Any major mods required? Are there compatibility issues?
The reason I'm asking is a guy on Rennlist just spent a small fortune replacing his 997.1 motor like-for-like. Apparently there are no more new 997.1 engines in crates lying around the Porsche factory anymore. So if you want a new 997.1 engine, they have to gather up all the pieces scattered about and build you one. Hence the high cost. That made me wonder about the feasibility of using a 997.2 engine instead.

I'd imagine a new wiring harness and ecu. It would probably cost more than the car with a blown engine was worth. Assuming the transmission bolts on and is a manual. I'm not sure a crate .2 engine would be any cheaper. Getting a short block .1 means that can use most of the parts from your existing engine. Getting a .2 would need to be a turnkey.

I wouldn't attempt this unless someone gave me a .1 car and a .2 engine for free.
Best to sell the .1 and buy a .2 car. It will be a black hole of $$$ and effort.

Get the latest issue of Excellence and read the Tech article on dropping a 3.8 into a Boxster - sounds like most of the issues will be wiring harnesses, etc....and expensive to do.

I personally have no need to do this right now . . . my 997.1 only has 17K miles and my car is running fine. However what prompted me to start this thread was reading about a guy on Rennlist who had to replace his 997.1 engine that crapped out after only 25K miles. It set him back $20K to install a brand new one. If putting a 997.2 motor in a 997.1 body is simple, I'm curious how much more it would have cost him to upgrade to the DFI.
I saw a low mileage DFI motor on Fleabay for a bit over $12K, but that did include a $3K core charge. I'm thinking you could drop in a used 997.2 engine and be in it for around $20K. But I might be completely off base since I have no idea what's involved.

Supposedly better for IMS longevity. Some also recommend 5W-40 oil too. Regardless, it's never a good idea to lug the motor at low rpms. We have a tendency to under use the motors here I think. These cars are designed for autobahn use and can handle sustained high rpms. To the point the exhaust glows orange.

You seem very worried about your car's reliability. Recommend you trade for something with a warranty for peace of mind. I'm sure you have no plan to do that, so while you own your car, keep the revs above 2,500, and change the oil annually at a minimum. Don't baby it, it's a Porsche.

Overreact much? I read the first post. The factory not having replacement motors on hand doesn't keep me up at night. Why speculate over something with such a low probability of need? It's not even an interesting topic as it's ridiculous to imagine doing it.

If it's not an interesting topic to you, then why are you responding? I asked a simple question which you don't appear to know the answer to. Instead you offer off-topic insight into my state of mind, tell me to sell my car, and offer tips on how to drive these cars. Your comments serve no purpose other than to be argumentative.

Not sure it will just bolt up easy. I think I remember Porsche saying when the new DFI engine came out that in addition to the fewer number of moving parts in the engine, the engine actually sits lower in the car than the previous engine givng a lower center of gravity. So, if it does sit lower, it might not just be an easy bolt in.
