Default Built 2.0 Power/Longivity

My 2005 WRX is currently at a Subaru Specialist shop being rebuilt because of some pretty bad knocking. These are the details I have that are getting done. It is going to have Wiseco pistons, ACL bearings, stock crank, and stock rods. It is going to have .0028" clearance. We are also going to be running a catless downpipe with a no name 3" catback. Would I be asking to much with this setup for 230 WHP and still have a very reliable motor that will last me years down the road?

I babied the crap out of this car before it blew up. I can count on 2 hands the amount of times I even went above 5700 RPMs, mind you I've had the car for 3 years now. With forged parts, better bearings and a little more power I am of course going to want to have some fun here and there a little more than I did before, but it will still be babied. What are your thoughts?

I ran my stock 205 well beyond that and beat the **** out of it with no issues. Ran it for over a year at 375whp and 6 months at 396whp with no issues, still alive and well in another car 145psi+ on all cylinders. Also revved the car to 8k all the time.

That being said if it's apart you might as well go to a stock 08+ STI rod. I believe when I built my cousins car they were like $225 for the set.

Damn, that was on just your stock block? Stock internals and everything? Why is it you hear about people building their blocks and then seeing them blown up 10k miles down the road then?

Bone stock never cracked open. Only part that was altered was the intake manifold for tgv deletes. And because people build engines to run the piss out of and beat on. They will push them to far unlike the safe tunes everyone wants on a stock engine. Honestly there is no one that can build an engine as well as Subaru can so once there cracked there not the same. A lot of built engines are done sloppy and tolerances aren't right.

Cheap out on tune/parts. I've seen people put thousands into an engine and don't pony up the $600 to get it professionally dyno tuned. Those motors usually last a season or two before I see knocking or some other issue.

My built 2.0 lasted roughly 24k, 19k at 400whp, 3k at 450whp, and roughly 2k at 520whp. The engine still ran when I pulled it. The tuner that tuned it to 520 had given to much timing and the detonation started killing the mains. Had plans to just freshen it up and go again but got a deal on an Mps 2.35.

And definitely a lot of it is in the botched tunes people get and run.

+100000!

If your goals are 240whp and to last a long time I'd get a new block from dealer ($1800) and get the heads rebuilt and thats it. KISS...keep it simple stooped

No need to really build the block for those goals but if you do I'd suggest king over ACL bearings and STI rods. I do have a set of STI rods and a good EJ207 crank with the cross drilling for better cooling that I'd make a good package deal on...if interested send me a pm.
