I want to put this ls2 in my Camaro and run between 8 and 12psi and curious who's running boost on stock unopened ls2; stock compression, stock internals, bolts and headgaskets.

 

If no boosted ls2s how about completely stock ls1s that added turbo set up with no modification to the motor?

 

I was running a stock ls2 at 500 RWHP 5k miles then up to 750 rwhp for 6k miles back down to 650 rwhp for 7k miles. I just blew it, pulled it out today, think i spun a rod bearing will know tomorrow when i get it on the engine stand and pulled apart.
Its blew on a cold start in the driveway. motor had a total of 35k on it. its been though 6 sets of tires in that mileage so it been driven hard.

Pulled heads off those look great/ piston are looking fine too. crosshatching on walls looks brand new almost, was spraying alot of meth though it might wash down the walls but didnt. Dam rod bearing

 

954
Did you run stock compression and curious what boost levels where running?

I assume 954 is your bike?

 

10.9 to 1 compression boost was run from 10 psi up to 16.5 psi.

Yea 954 is my bike I love the liter bikes just stupid fast and still handle

 

Yeah, glad to hear u got away with that much boost on stock ls2.

I put 40k miles on my 929 fireblade and love all the adjustability of sportbikes stock.

 

Well just riped down motor everything looks brand new bearings every thing. But one rod the 3 or 4th one is bend and riped out the bottom of the piston.
Trying to figure out why ? If it wasnt for this. motor looks like it would have went forever.

Ah nice bike i do love the honda bikes just hit 30k on mine

 

954,
Maybe your rod bolt stretched allow for loose rod ripping off your piston?

Curious if you did more research on what happened.
