I am just after people opinions on the Con Rod strength of the Vl Turbo i know the crank is strong but the rods i can't get a straight answer some say 500 some say 600 and i heard a place called JB Performance use them in their hipo 3 litre GTR engines, id appreciate anyones comments but preferably those who have played with them. I would also have them peened, close honed and side polished as well as balancing them.

I've been told that Nissan rods generally have a design limit of about 100HP (per rod). This came from an engineer who worked for Nissan when they manufactured cars here (80'/early 90's). However, the real weak point of a conrod is not the rod itself, but the rod bolts.

yeh the rod bolts on nissan rods are shit to say the least i know of a couple of 9 second vl's running shotpeened polished rods with arp bolts.

There is a company in adelaide they are called argo and make rods and there no where as near as expensive as carillo's jst a thought

Hi guys, GR8NES asks..............

"Does anyone know the ARP part number for the rod bolts to use ?"

That seems to be a closely guarded secret, ARP know but won't tell you because they sell them to a Japanese tuning shop (HKS, I believe) and most likely have a secrecy agreement. The local guys who know like to keep that sort of stuff to themselves (intellectual property), they can charge more that way.

What I do is measure them (head, rod & main) up, or send a sample and order them by the specifications, not the part number.

Hope that helps.

Hi GR8NES, last time I did the numbers, to close and hone, shot peen, polish, floating gudgeon bush and balance a set of rods plus the cost of a set of oversize rod bolts with rethreading, it was cheaper to buy a set of Argo I beam conrods. For not much more I could have a set of H beam Carillos.

Since then we have automatically gone straight to Carillos, I will check the costs again for our next RB31/RB26 but I would be surprised if things have changed much.

Hope that helps.

Hi guys, while I was searching for some other data I found an invoice for some Ford Cleveland ARP rod bolts, since I haven't done a Clevo for a while (about 10 years) I suspect they found their way into an RB engine. The were Pro Wave ARP 2000 in P/No 254-6403, which have a Carillo "C" type head style which is the same as Nissan use. Compare the specifications, they may be the ones you need.

Hope that helps.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
