Hey guys I’m brand new to the Subaru world, from the US living in england. Always had v8 American muscle, bought a 97 WRX. Looking for a good place to buy parts from, plan to just go bigger turbo (with supporting mods). Can the ej hold roughly 400 crank hp? Forgot to mention it’s a jap spec vehicle. Thanks in advance 

Wotcha and welcome - feel free to create a build thread and share your progress. Check out @savage bulldogs wrx thread for inspiration.

To answer your question, I believe that is pushing the limits of earlier cranks so you would be better going for a later crank and completing the bearing modification.

Parts - depends what you want and if you want brand new or not?

 

Standard centre thrust crank is good for 500hp + afaik but the pistons/rods are on their limit at 350hp and its probably a open deck block , which is probably limited to 400hp .

The early 5 speeds are the weakest of the bunch too , so it depends on how deep your pockets are and how far you want to go .

Generally the sweet spot for a classic is 330hp at the fly and weighing less than 1300kg , its probably enough . It also means that expensive engine, drivetrain ,turbo and injector upgrades are not needed at that level too 😉

Keep us posted on which direction you want to go and we'll help if we can , bud 👍
