Free rods, $70 for bushings and machining, $120 Vitara's, that's far less that TT's right there. Add in $30 for some ARPs, and now you could probably be safe spinning to 8500.

Re: Vitaras w/ ls rods
There's a thread in GD where a gentleman picked up forged rods and pistons for $200.
LS rods are fine to 8500 rpms, with stock rod bolts and an 84mm piston. It was both Belben and Rocket's opinion an LS rod D16 would be good to 9500, good luck getting the head to flow for the last 1000 rpms.

$30 bucks for safety isn't bad. Long term, LS rods will give. Lightweight 84mm?
Their estimates are too high. An LS weighs has more inertia than a D16 rod, and at 9500, a D16 will spin bearings. A D15 stroke maybe.
I currently run it to 8200 on a stock head. And yes stock heads flow like ----. A nice cammed and ported head, and I would've been looking at least 340.

Maxie-san, I have yet to see a rod break that wasn't related to a mechanical over rev or oil pump failure that welded the big end to the crank; that 300 whp stock B16/LS and 350 whp stock GSR rule of thumb stuff is all related to stock piston-wall clearances, and if you set that loose I'm pretty sure a whole lot more is possible on a "stock" engine. The piston will always be weak if detonated on, but the OEM carbon drop forged rod is a mild form of excellence.
