Gt Nismo Conrods And Crank

[pnblight]

Hi guys,

Was just wondering if anyone new the length of the std conrod , as i'm looking at the GT Nismo crank and rods (the crank looks to be around 78.5mm stoke and the conrod length 121.5mm)i know the std stoke is 73.7mm but i dont know the conrod length? Has anyone used this items in a build up?

Are you still looking at an N1 block as well Pete?

no but i am interested in the gt crank, but i already got Pauter rods which i would most likely have to sell if i when down this road and buy the gt rods or something similar.

Pete...that is std Rod length. You need to use special pistons which run a smaller (by 2mm) piston pin height

OK THANK YOU GUYS

so i can keep the Pauter rods and use a GT crank but have to run special pistons to allow for extra stoke?

I'm thinking some of the after market kit might have gone down the same road with pin to deck height reduction (hks 2.8 etc) will have to see what i can find out and prices of the nissan verses after market gear.

You could always get custom pistons (2mm smaller pin height) and use the GT crank with your Pauter rods. The GT pistons are not forged.

Incidently, the crank that tomei supply with their RB28kit looks alot like the NISMO GT (Z tune) crank (I reckon it is the same one).

The Tomei crank uses shorter rods, 119.5mm and standard pin height on the pistons. But the Tomei rods look much nicer(and lighter) than the NISMO ones.

The longer rods would be better for RPM, but apparently the Tomei kit is still good for 9000RPM +.

i thought the gt pistons were forged as in the Z tune specs they talk about forged light weight pistons (z tune uses all the gt gear)

trying to confirm this at the moment and see if i can actually buy the gt pistons

the standard lenght is 121.5mm

the get around it by using a heigher pin height on the pistons.

besides the gt crank isnt a full counter one!!!!

acording to the pics on the nismo site.

Hi Pete

I'm using Pauter rods on my 2.8L crank, but as per the advice above I will use pistons with an altered pin height (HKS in my case)
