on an sr that would be considered a heavy build. Not to be taken lightly, in other words the small short cuts taken will show up not in your favor (stock bearings, not replacing vital parts(oem oil pump), head/main studs, proper machining, etc. YES people have run oem bearings on there 500hp sr but its risky thats my point, you dump thousands in parts and you cheap out on $200 worth of bearings, thats tard in my book.

i'd run oem bearing in a ka they dont make power! jk jk
