easy as...if only they did next day delivery

Yeah, i woudlnt worry about it in that situation so much. Heck my daily ive reused the bolts heaps of times. Im just paranoid about the race car because the ONLY time its NOT being thrashed is when its driving on and off the trailer.



From what i understand autos are a different matter, as they dont have the same sort of shock loading as a clutch, especially a multiplate savage clutch. The TC takes up the brunt of the changes and leaves it relatively ok. Plus its a lot thinner and lighter (the flex plate) so the bolts have a lot less weight and thickness to shear. That being said, i have seen photos of a flexplate in the dash. Ill find them.






Although i think that noob shifted into reverse at 100km/h and blew the trans and the flexplate together.

I need say only one word: Falcon.

Same bolts as 4AGE, hence probably the same torque specs:
Flywheel Bolts: 74Nm

Just to let everyone know, I installed my ORC twin plate over the weekend, and while the torque specs for the 4A-GE were 74NM (well, 76, but close enough), the 1jz/2jz-GTE were both listed as 117NM. (as per the ORC instructions).

Admittedly, loctite should make sure that nothing is ever going to rattle loose anyways, but better to be safe than sorry

Incidentally, the RB-26 takes 134NM!

Cheers,

fuck, thats fantatstic knowing this just recently having my clutch installed with 74Nm :S

you HAVE to use loctite though on the 1jz as the holes go through the crank and oil WILL seep out through the bolts.

Interesting, the Toyota manual i took a squiz at says 74Nm.... I wonder if its an ORC thing? Certainly ARP give different ratings for their bolts.

I believe 74Nm was for the R154/7MGTE combo
My notes indicate the R154/1JZ-GTE & 2JZ-GTE/V160 as being 48Nm+90 degrees which is what Exedy recommend for their Clutches on the 1JZ-GTE/2JZ-GTE as well.

But 48Nm+90 would mean that the bolts are torque to yield as per the head bolts. The ARP bolts certainly arnt TTY.

There's a mix of quotes between OEM and ARP bolts throughout the thread, so yeah, care needs to be taken when referencing what - 74Nm and 48Nm + 90 degrees is from the service manuals for OEM bolts.
