1JZ Rod Bolts

[xsjado]

I'm chasing some rod bolts for my 1jz and just need some advice, firstly is there anyone besides Toyota who makes these because it is going to be a 3 week wait if I get the bolts from Toyota, secondly I have been told that 2JZ rod bolts can be used, but they will yield tighter or some crap and lead to a higher chance of a bearing going on me.

Third option which I don't really like is reusing my old rod bolts, if I was to use them for the 3 weeks it takes for Toyota to send out some new ones would it be safe? Or is it best to just wait out the 3 weeks or take a gamble with the ARP 2JZ rod bolts which is a 2 day wait...

2jz bolts work fine.

ARP work even better., that's the best bet out of all your choices for a nice long lasting motor. Otherwise, what soapra said. Make sure you plastigauge everything if you're installing new bearings, that's what your mate probably ment when he told you about bearing failure.

I would order a set of ARPs for a 2JZ, and use those.

Should be getting my ARP's today. Would I be correct to assume that you torque to the same specs as a 2jz? I don't really trust my mechanic, and since this is the last thing he will ever do to my car, want to make sure he doesn't break anything else . Thanks

yes, the torque specs are the same.

Remember, all the bearings are the same between the motors, and the rods are physically the same too, aside from their length.

After you install them, you must have the rods resized with the new ARP bolts, to make sure that the big rod ends are still round.

thats only if they are pressed in studs not bolts. as for torque specs follow ARP instructions! dont torque them to factory specs. and use the provided assembly lube.
