I have a GSR short block with wiseco 81.5mm 11.8:1 CR, but the conecting rods are still stock, the cylinder head was b16 PR3 ported and polished.
Now im running ITR camshaft and toda springs on this motor and often rev-it to 8200rpm and still safe until now...
My friend offering to to put his JUN3 camshaft for my motor for free, but im affraid my stock GSR Conecting rod will not handle the revability of Jun 3 camshaft.
My question is how high RPM Stock GSR rods can handle???
Anybody ever try "WILD" camshaft such as jun 3 ,s2 s2 or toda c with stock GSR rods???

 

just dont rev that **** to 10000 rpm...my gsr rods have seen 9500 rpms with no problem with skunk stg 3's

thats what i call GOOD NEWS ! How big is your Compression ration with that skunk3 ?? Was CR will be also an issue to this rods realibility ??

 

my buddy revs up to 8800-8900rpm with stock GSR head track only. Its pushing 570whp and runs 10's...turbo of course.

im using ctr pistons...wich should be around 12.2ish

 

My old ones in my old block with 11.7 saw 9k+ alot, daily, for almost a year. Car was fine. Just make sure your work is done right, and those rod bolts arent old.

 

oh yeah i forget to mention that im using arp 9mm rod bolts

 

humm... how if it on stock bolt ???? is it danger to rev 9k with stock grs rods and bolt ??

 

Whever you rev past stock redline, keep in mind that parts like rods are designed for fatigue, not ultimate stress. They're probably also desinged for infinite life, which means you can hold it at redline for a loooong time (I'm talking weeks, with no rest).

What this all means is that they'll survive 9000rpm, they'll survive 10000rpm, and they'll survive 12000rpm (I've seen it). They just won't do it for nearly as long as if you kept it at or below stock redline.

 

ok thanks , so the i know the ITR redline was 8400 ,but i never seen GSR dashboard in my life (i only have the engine and tranny in my EG) so i dont know how is the redline of gsr ??..
