Thread: Need: JUN H-Beam Conrod Torque specs

Hello,

at the moment we are rebuilding a SR20 engine.

The engine was equipped with JUN H-Beam conrods.
Unfortunately we can't find any information about installing this rods the correct way.
Neither the owner of the car nor the repair shop who installed the rods years ago can provide some information

The only information we have are:

Jun H-Beam Rods (the first owner of the engine told us that conrod manufacturer is JUN, and you can find a "J" stamped on the big end).
The bolts are marked with CARR.

Can anyone provide us some torque or installation specs for this type of rod?


thanks Ronny

I'm gonna guess 50lbft.

you cant find this through JUN's Japanese website with a translator?

measure the carr bolts then look up the torque specs. I know arp bolts have their own torque specs that are used by manley and eagle.

you will need to contact them. depending on the material used the torque specs can vary up 25lbft.
