3.4 to 3.6 swap?
johnmh replied to johnmh's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
Thanks. Any suggestions for a good source for cam retaining tools? I managed to successfully remove my double row IMS this morning (it looks to be in excellent shape) so I am slowly gaining confidence with the 996 motor. I have the cam locking tools in place which are part of the LN IMS kit. I suspect these locking tools alone will not secure the cams to avoid the risk of breakage. The idea of a cam being so fragile that the valve springs can break it seems odd. I will search for posts re chain wear pad replacement. -
3.4 to 3.6 swap?
johnmh replied to johnmh's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
Thanks for the information; the variocam issue was not one I thought of. Another 3.4 would be preferable should I need to go down that route. On the issue of variocam, I note that the cam chain buffers wear over time and was going to pull the cam covers to inspect mine. Can the buffers be replaced with the cams still in the head, or must everything come off to do it? It seems like a bit of a pain on a 5 chain engine. I searched the forum but did not come across any article on the job. -
I have my first 996, a 2001 manual US spec cabrio. Car has 78,000 miles on it and needs a big service. I am in the process of performing an engine out service on it to change the AOS, clutch, IMS, RMS and to generally just check it out. Interesting engine. I am a long term Italian car guy and am still learning about 996s. While it will likely fit, does a 3.4 to 3.6 engine swap require an ECU swap as well? Anything else? I have to assume that many others with bad or worn out 3.4 engines have done this (I understand good, used 3.6 engines are more plentiful).
