Whether I should bore my 3.4 to a 3.6 and go with (aftermarket parts), or just stick with OEM. I called a ton of shops and all of them had mixed opinions. A lot of them liked using aftermarket parts because its cheaper, but there were actually more shops that recommended sticking with OEM because they all said its (Porsche) they're not exactly using cheap materials to build there 14k+ engines. 1 shop in particular definitely didn't like using aftermarket pistons, heads and so on... because he owns a big reputable race shop here in CA and hes had various complains of owners blowing there engines on the track and just sticks with OEM. Anyways, I finally made my decision and just stuck with OEM. I purchased a used low (mileage 32,000) 3.6 C2 996.2 engine for $6,500 + $1,800 labor and have no regrets. And from what I hear upgrading from a 996.2 3.6 to a 997.1 3.6 is about the same thing (labor wise). Just my 2 cents. Hope this helps.

How much will the swap cost roughly?

Is it worth it for the power?

New Porsche guy sorry.

Some people think the 3.6 had less but that is not true at all. Both engines suffered about a 10% failure rate however IMS failure happens around 20,000-40,000 miles. My pre-modded engine had 106,000 with the orginal IMS with no problems. The 3.4 has a bad wrap but is a very strong engine! Its down fall is poor cooling, once upgraded with a 3rd Raditor and lower temp thermostat it has no issues.
