Tomei
Tomei compared rods on the factory FA20 to the Factory FA20T and discovered the FA20T rods were a heavier design. Also the pistons were heavier design even tho they were 10.6 compared to the 12.5 FA20
http://dsportmag.com/the-tech/tomei-...a20-flat-four/ I guess Subaru engineers didn't feel safe pushing FA20 stock rods to even 268hp @6700rpm at the crank was safe.

So increasing power for an OEM will mean a change to ensure parts last 250,000 + miles. That being said reasonably increasing power will affect partlife but it will mean an engine lasts only 100,000 miles vs 250,000+ |

I guess it boils down to what people expect it to last too, in when considering calling it safe. I do not believe 100k scenario will be possible going f/I on a FA20, but that's just my opinion. But your statement has merit for sure.. EDIT

I guess you will not have too long to wait considering some people are over 100k with combined NA and turbo time

I'll start. I did 3miles with 1000WHP so it must be safe. Anyone that blows an engine on less power must have had a bad tune.
Is that a good enough fact? |
