Upgrading 2000 2.7

[JFP in PA]

If the engine is a dual row bearing, around 1% or so failure rates would apply; but the problem is that many engines were single rows, where the failure rate is 8% or more (from Porsche's own data).

Physically, the 3.4 is a bolt in without any mechanical changes (assuming it comes from a similar year in terms of the fuel system). The DME is another issue entirely.

60+ hp from a chip. You don't believe that? Try maybe 5 hp. Don't waste your money. Here's a hint that it's bull, no one calls it a "chip". They stopped chipping cars about 25 years ago.

For the most part it's really hard to get any extra extra horsepower out of these cars without a engine upgrade which is alot $$$$. Keep your money or spend it on maintaining the car properly so you can have it for a long time.
