Parts for replacing stock bottom end My cam requires a little more space and I want to
raise the limiter to about 7300rpm and shift at 6900rpm. I have the G5 cam and on the dyno my peak is at 6870rpm. I have the shift points at 6500rpm and limiter at 6800rpm and I'm not happy.
Will replacing my bottom end help any! <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

The bolts are the "weakest link" (sorry) in that engine. At the very least get some Katech bolts. The best thing would be to cross-drill and nitride the crank, and rebalance with some GOOD rods and pistons.

Re: Parts for replacing stock bottom end How much is it overall just to beef up the stock bottom end...
When I do it I would most likely step up to stronger rods, pistons, bolts....would that be under 1000??

Re: Parts for replacing stock bottom end rods alone are upwards to 1000 depending on what you get. You can get the Lunatis for ~700 but there is a significant backorder on those <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
Pistons range 700-800 bucks

Re: Parts for replacing stock bottom end So 700-1000 for rods, 120ish for rod bolts, and another 700-1000 for pistons...so its around 1500-2000 bucks to have a pretty damn good bottom end??

If you do the measuring/assembly yourself. Add $1500 for a good shop to assemble, if not.
