Sure, everybody knows that one rebuilt engine that did pass 50k miles. There is always 1 guy who claims this happened and maybe it did,
but when you compare that there MIGHT be 1 single rebuilt engine out there which can somehow manage to reach 50,000 miles with the fact that every single factory sr20 is guaranteed to surpass 250,000 miles (when treated properly as we've seen they all can) Its a no brainer to avoid the rebuild altogether considering the end result, and what do you get from a rebuild? If its a stock rebuild you get nothing for all that trouble. If its a slew of aftermarket parts, what this really means is heavier internals (stronger) which can support an additional maybe 100hp or 150hp over what the factory internals can (400-450bhp = Factory, 450-600bhp = aftermarket internals)
Then compare the cost of aftermarket parts plus assembly WITHOUT the risk, lets say the rebuild is 100% successful what do we have? Around $6000 invested in the build for an additional 100 to 150hp from a 4-cylinder thats lost all it's low end torque and most of the daily drivability and spool character.
NOW factor in the risk and the fact that I've never seen an aftermarket internal sr20 reach 50,000 or even 35,000 miles (Sure there is that ONE but...)
And when your done thinking of all that risk, consider that there is an engine out there called an L33 which weighs the same as the SR20DET and can support 1600bhp, around three times what an aftermarket parts fully built sr20det can acheive, and that the L33 will easily 250,000 miles just like the OEM sr20 engine. Oh and to top all that off, the L33 is roughly half the price of a stock sr20det.
Its a no brainer. Don't try to rebuild anything. Just use the correct OEM engine for the application and be done.

According to my SR20 specialist, you need new headstuds and a new gasket to go past 300 rwhp. Should I just ignore that recommendation or is that what I should do with the new long block?
Actually hmmm I need a new thread. I mean this isn't even about the turbo anymore. This is a Rebuild vs New Motor thread. I am honestly quite unsure. My mind is being split in half.
