You're fine on the rods, but I don't recommend trying to save weight on the pistons. It's better to have a piston that is strong and able to absorb/dissipate considerable heat. Any of several popular options often discussed here will suffice.

 

Ted,

In reference to the custom 585g 156mm Oliver Billet I beams that you're using......Are they the new Turbo Extreme series? If so, what do you think an estimated weight would be for the Turbo Extreme MT5906LT-G2? Do these use the older wider rod bearings?

 

I'm using the narrow journal rods. The 'Turbo Extreme' is something relatively new. I do not know the weight difference. They use beefy 3/8" bolts - ~19% larger than std EVO rod bolts.

 

I guess I'll have to call Oliver tomorrow and find out the skinny...........

 

Ted, Write a book on the evo and after market parts for the 4G63. So then instead of telling everyone on here to "SEARCH", we can just say, "Buy Ted B's book".

 

seriously thanks for the info.

 

this thread was an interesting read. I learned something. Thank you all for those who contributed.

 

pardon the resurrection, but what is the weight of the factory evo rod? Combined with a lighter crank like the wynberg how fast can an evo rev? According to elementary school math:

Over 400 grams savings on rotating mass from stock
7 pound lighter crank = 3175 grams lighter

Total over 3575 on rotating mass. How does that translate to the speed of the engine revving? Can the rev limiter shoot from 3-8 in a flash due to the weight savings?

 

there is a lot more to fast revving than rotating mass.

 

I wish there wasn't. I guess the main benefit would be to reduce the bearings being beaten badly. what other changes can be made to the evo for faster revs? I know it cant reach motobike territory, but any improvement is welcome

 

bump for old thread because I am deciding between which oliver rod to select? Is there a rod with the 3/8 carr bolts and one without? Anyone know the weight difference?

 

I have them. Ive used them in all my builds.

 

my current build has the Carrillo pro h beams and a winvberg crank and is on a stand at CBRD.

I chose this rod for many reasons first and foremost was weight, 2nd was carrillo has never failed me or my friends, every other brand of rods has....

 

i hear great things about the carrillo just costly. THat crank is amazing man, but that is the price of a built motor here lol

 

Do it once do it right....
