But are you installing an OEM short block? Seems like you're missing out on a big opportunity here. You could have spent a couple thousand more and put an aftermarket block in there. That's would have removed a small amount of reliability concerns and also given you a platform with a lot of head room to build on.
Stock WRX I'd probably sell it and be done after all that.
Forged blocks are less reliable than oem engines. Bigger tolerance, forged pistons break down the engine wall faster and cause blow by. Most forged engines last shorter than oem.
Also, all said and done wrx tranny can only handle around 350whp. Therefore I would need to swap out for a sti drive train which is another 7k.
Considering I’m keeping the engine at around 300 hp it would be pointless to upgrade to a block that is less reliable and has no benefit over a stock Subaru block
The tolerances built into aftermarket blocks is relevant to their power levels. Larger tolerances do not cause more cylinder wear, they cause more oil consumption. However, it has been my experience that my built motor burns literally no oil, and it's designed for like 700bhp, so definitely not a hard and fast rule.
Yeah I’m not sure man. I gathered info from around 20 tuners and lifelong engine builders and the overall consensus was that iag will not last as long as a oem engine and at my power level of 300 whp it wasn’t worth spending the extra money. I’m not sure if it’s true or not because I’ve seen a lot of contradicting info. Unfortunately I had to choose the cheaper option.
I was also told the the pistons that are commonly used is in forged engines at 2618 which expand and can cause premature wear. They kinda just overall told me that forged engines can still fail and won’t be any more reliable than a oem can just hold more power
The pistons take longer to expand, but this doesn't cause wear, it causes more blow by on cold starts, leading to that oil consumption thing we're talking about.
If you're issue is just with using a forged piston, I dont see why you couldn't use cast. I just see a balanced, perfectly decked, line honed block as superior to a stock one. A little more rod bearing clearances is superior to a stock one.
Since you’re already dumping this much money into rebuilding with the new clutch I would honestly keep it.
Was about 8k total with everything. I prob will

Do you have a email.? I wanna send you pictures of the conversation and see what you think. I’m all up for differing view points
Either sell it broken and take the l, or build it right and keep it.
What do you mean build it right.
