char19822 - The Evo's have much stronger blocks than any Subaru, because the Evo has an iron block and Subaru's use aluminum blocks. However, and this is key, when you're going into HP numbers that high, it comes down to rod/piston strength more than block strength. If you're building a drag car (i.e max HP), get an Evo. If you're a real driver and want a twisty road brawler, go for the STi (MOAR TORQUE!). 400whp is more than enough unless you wanna race lambo's and the like on the highway.

@rallifreak well said, the interesting point is the new EVO has an alloy block!

i understand that i seen an autocar test saying the version 5 didnt seem as quick as they thought it would, the aussie one,so maybe your right,im sure your company run a great service, as my posts are not aimed at you,just so people understand that its not just the ej20 that has these problems,and subaru produce great drivers cars.

Not really an explanation...

The world always have two sides, engine too. An EJ engine keeps center of gravity low by compromise short stroke piston, longer header, longer intake manifold (even longet with front mounted intercooler setup). With this setup the main bearing will got a lot more stress than any other engine at high loads. Most of poor EJs dead because the driver brutally increase the boost without proper mod, low quality oil, low octane fuel, etc...

Everything has its own limit. So use it wisely.

@MrMrdavehawkeye :Hi there

I read you're a Subaru mechanic. I'd like to ask for some advice , if you don't mind.

I just bought a new Sti, I didn't know about this bearing issue they have. Is there anyway to look after this engine? Anyway to prevent the big end bearing popping?

Why does this happen? Is the bearing low quality or does it come down to oil starvation in corners? Why doesn't Subaru solve this issue?

Hmm hard to say, they are both great engines, depends on personal choice.

Its not really an ewasy question for me to answer without having the car here and the end result
