Thread: VH45DE Pistons in VE

I have called CP and left a message. Since they are not "COTS" pistons, and are all custom order, they don't advertise in their catalogues.

Hmm, I'm not sure what 16ve rods weigh but stock de rods weigh in at 630g. Manly h beams are 512g!

a 93 mm CP piston will be about 355g from my calculations.

The CP 92mm piston and some Manley rods are the way to go.


now if you look at the average 86mm SR20VE-SR16VE piston at 331g and the 93mm vh45 piston at 402g, thats 71gs diffrence.

guys a madman

Go for it open the envelope for new things and remember you are the first one the rest will be followers...
And even more if you are willing to spend the money and do all the hard work and share your findings....

^Pretty much. Be an innovator, not a replicator. 2010 should be a good year!

Regardless the extra weight of the piston if everything is balanced and what not the motor should run fine. Hell I would assume the extra displacement would make up for the extra piston weight.

LOL no the strain on the rod will become exponensial higher. Mean time between failure will go down with alot!!!

This is the stuff people dont understand. That 71g is about 20% heavier than the standard piston. This is huge, more so on an engine that we are trying to rev from 8500-9500 RPMs to make power.

I don't understand what people are complaining about?

The strain on the rod?! You guys are talking about rods that hold 400whp. THAT is a shit ton more strain than a mere 71 grams of additional piston weight.

FWIW, I would be more worried about wrist pins than rods, and you don't see those failing on 400whp motors either so...

Let the nay sayers have their conversation, J. Do it like you're going to do it anyway, and show the results
