PRISM Forged Conrods

[Schneider]

Didn't see anyone posting anything on this here so thought I might. Interesting group buy for forged conrods!
For those thinking about jumping to TD04's and beyond, ~$930 for forged conrods + ARP2000 bolts based on todays exchange rate. No idea on shipping though.

Hi-Performance H-Beam PRISM connecting rods. Now You can built extreme powerful engine and produce more HP without worry about damage it. All PRISM rods are produced from one-piece forging, Cr-Ni-Mo 4340 alloy, and have special 3D design, so they are stronger and lighter than stock connecting rods.
All PRISM 4340 connection rods feature...

• Ready for installation 3/8” or 7/16” rod bolts (see Your application)

Also noticed in the same thread that Wiseco are making pistons for the VR4. 2 different CR available 8.5:1 & 9.5:1. Bore sizes are 81, 81.5 & 82mm
Prices are $830USD I think for a set.

2 grand for forged internals isn't so bad.

I hope they will be available in the future, I don't need to do my engine yet but when I do I wanna make it strong

 

[sanchez]

I would have bought the Wiseco pistons for my VQ35 but they won't make be a custom set for my stroker. Otherwise, very good lightweight pistons with a lot of excellent feedback on the 350Z website in the US.
Yes they mainly make motorbike jet ski and other recreational bits, but their foray into the auto sector has nothing but good rapport.

Yeah they should be available. CVR4 was just looking for an initial set of 5 buyers so PRISM would go ahead and make the die I believe. So I wouldn't worry.

Rumor has it Wiseco is also making 10.5:1 CR pistons as well for the E85 boys. Its starting to make me re-think V6 - 4 Banger

 

[Macca]

Wow, it'll be great if these parts are going to be readily available. Nice.

 

[Bennoz]

Yes please, Group Buy!

The group buy for the rods has started here: http://www.clubvr4.com/forum/showthread.php?64571-Forged-Conrods-Group-Buy&p=711672#post711672

 

[jungle]

~800AUS but then you need to + rod bolts + shipping. Plus i'd be contacting them to make sure they've acutally made them. There is a lot of info missing which leads me to suspect they haven't made any &/or they haven't updated the website.
I seem to remember me organising a group rod & piston buy 2&1/2 years ago which fell over cause people committed and then pulled out...

Did you opt for ARP2000 bolts, rods alone appear to be cheap on eBay at the moment $600.00

 

[R Kilburn]

what about crankshafts are they not neccessary?

 

[AKKO]

I remember reading somewhere that its forged from factory... how good that is may be a different story?
