hello can somone tell me what the tourqe setting is for conrods-- fsm is 15nm then 60 degrees, thats a crap way of doing it, fair enuff on head bolts but. bit risky on rods. some say 40ftp on mains and same on rods,, 40ft pound? is alot for rods. anyone?

its holding me up in my rebuild. thanks guys

Factory rod bolts and main bolts 50nm for both.

FSM says torque in kg/cm2 or something....nothing about 60 degrees.

If you have aftermarket rod bolts/rods or main studs then these settings will be different

cool thanks. seems to be alot for the rod bolts tho? this is what i have in fsm---14-16NOm (1.4-1.6kg-m) mark with white marker and turn 60-65 degrees. ??? told have to turn in degrees as bolts tend to strech a bit.. i was going to tighten to say 20ft pd,, but u think 50 ftpnd. can i ask how u got tht,different manuals?

when you have the torque wrench in your hand and and you click 50nm onto that rod bolt, tell me then that you think it feels like too much. I reckon it feels like not enough. But it's not a matter of how many nm or ft/lb required, it all comes down to bolt stretch. If you have a stretch gauge, torque them down til you see 0.006 stretch and that will be spot on.

sounds bloody good to me, ill go and finish her off. . all my other motors,long as theres bit of movent all good, ill let no how they feel .

Also I have run this on two RB25 engines that still used factory rods and bolts and they are both over 80,000k old without issues

yes thats tru. they do lock once load has been applyed ,started. so it should be 36ft p

thts good because i done big ends at 35ftp

yes i have built diesels to 202's to sr20's.few other types,plus bikes 38models to 2000.

when i said movement i ment, once tight, you should be able to still move rod foward and back a bit. all good sumps on.

What do you mean by movement, torquing the rod bolt shouldnt effect bearing clearance.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
