You might be jumping the gun there with the 3.6 idea, i know of only 1 person who has done that on the 986 and hes still working out the kinks, the 3.4 however is doable but the engine costs more and there still is some mickey mouse work involved that the indy-mech will have to dive into. I'd consult with the mechanic even before you purchase the engine.

Actually, I think the 3.6L swap would be the easiest and best swap for my car. The 3.4L from the 996 is designed to work with the Bosh motronic 7.2 ECM that was on pre-03 boxsters and pre-02 996's. The 3.6L in the 02-04 996's are designed to work with Bosh motronic 7.8 which is what my car has. I believe I can reuse my current ECM and the swap should be fairly clean as far as swaps go. Of course everything is dependent on what the dealership says so yeah, it's a nice idea, but I don't know if it's in the cards yet or not. If the engine does need to be replaced they might say they will only replace it with another 3.2L even if I offer to kick in some more money.

Sorry to hear about the problems Adam. Good luck with that.

There's a local shop here who advertises 3.6 engine "conversions" including swapping out the crank, new conrods & pistons, etc. Power output is bumped to a purpoted 360bhp.

I wonder if that saves all that much versus swapping in a 3.6 complete engine?

Although, I've read the newer crankcases have an additional crankshaft bearing to help deal with IMS and RMS issues(reducing crankshaft pertubations). So if true, I'd want to go with that.

I'm sure the best way to go is just swap in the entire engine. Besides parts, they would also have to machine the original heads and case to make way for the bigger pistons. Low mileage 3.6L engines can be had for 5-7k and I saw a brand new one for about 9k.

The 3.6 into your car is a straight plug and play swap, the 3.8 is as well. Just as simple as the 3.4 into the earlier cars.

However, since you have an extended warranty i wouldn't think it makes any sense to do the swap if you need a new motor.

Adam, what was the diagnosis?

Ok, I got word from the mechanic yesterday. They still don't know what is wrong. He and another tech drove the car and the CEL started to flash! So, they are driving the car around with flashing CEL and then the tapping and the CEL would disappear for a short time only to reappear again. They plugged in the diagnostic Porsche tool and it said cylinder 5 is misfiring. He said they are going to have another tech drive the car soon and see what he thinks. This doesn't sound like it going to be minor little problem. I'm just going to let them do their thing and sit back and wait.
