Is this rb25 still holding that power today?

[@AFRAutoworks]

As far as we know it is.

[@cryptoding6238]

What's up fellas?🙋 My homie at 3:33 ish. I'm a Honda fan boy, but damn that S15 is beautiful.😍 Wishing all the AFR boys and their families have a Merry Christmas!🎅 Keep up the great work!

Did y’all gap the piston rings bigger for the stock rings?

[@AFRAutoworks]

No we did not, but the car has ran for two years like this, and doesn 't consume oil and the cylinder leakage is good.

[@Icysoles60]

If its stock bottom end, whats done to the top end? Was it running stock head gasket?

okay no way that rb lasted long. Those rods probably snapped a month later

[@AFRAutoworks]

Still Running! Currently getting a new clutch installed.

Damn why people hate on the rb motors soo damn much??? Mine making 500hp on pump had it in my car since 2012 its still on stock internals except the HG and headstuds!!!

[@killianoreilly5416]

@@Teahairs I'm not hating on RB's I love them. My R33 GTR has been running 420 odd bhp sinse 2009 and it's still going. Love the engines it's just rb25's are known for having weak rods so I expected that engine to blow by now

[@Teahairs]

@@killianoreilly5416 its not the rods that are weak its the bolts ...you can't rev them high when making 500hp and up im guessing the bolts come loose and makes it spin bearings. My tuner specializes in rb motors he told me unless I was trying to make over 600hp i didn't need to change the rods.

[@dariochacon1351]

@@Teahairs whats the max rev when making that 500hp power
