R100 Posted August 21, 2011 Share Posted August 21, 2011 Ok removed my flexplate to fit a flywheel. Question, how far into the crank should the bolt go to be safe? The flexplate bolts are 10mm and if i use the flywheel they will go into the crank 10mm. With the flexplate they will go into the crank 13mm. Is 10mm sufficient or shall i buy some longer bolts. Should i use high tensile steel bolts ? Quote Link to comment Share on other sites More sharing options...
fuel Posted August 22, 2011 Share Posted August 22, 2011 I would try find the manual specific flywheel bolts, though buying from toyota would most likely be spendy. ARP do flywheel bolts for 3S engines, perhaps they could be the same for the JZ? Quote Link to comment Share on other sites More sharing options...
Simon Posted August 22, 2011 Share Posted August 22, 2011 I have same issue with 1uz. I'm using a 3sgte flywheel so I will just buy 3sgte flywheel bolts. Haven't measured the difference but not keen to use flex plate bolts on an already modified flywheel. Phils onto it. Quote Link to comment Share on other sites More sharing options...
Spencer Posted August 22, 2011 Share Posted August 22, 2011 If this is for the JZ I would get some factory or ARP new ones for sure, Also use a thread sealant on these as the holes go through to the crankcase If you get a special price from toyota they wont be to expensive Quote Link to comment Share on other sites More sharing options...
2JZKP Posted August 22, 2011 Share Posted August 22, 2011 if all above fails (very unlikely) head down to your local fastening supplies shop with thread pitch and length measurements and ask them for a grade 8 or higher hi tensile bolt to suit, in some cases you may need to run a washer so take that into account when measuring lengths, but go this road if all above fails, im sure arp will do something for you Quote Link to comment Share on other sites More sharing options...
R100 Posted August 22, 2011 Author Share Posted August 22, 2011 Just spoke with Toyota. Bolts are $28+gst each retail. My price is $23+gst each and they have plenty in stock (i wonder why) I realise i need the correct bolts so expect they wont be cheap. But at over $200 my cost for genuine toyota bolts i will try ARP first. Quote Link to comment Share on other sites More sharing options...
Alistair Posted August 22, 2011 Share Posted August 22, 2011 Could also try Nick at North Shore Toyota parts dept and say you're from Toyspeed and see if you get any better pricing. Quote Link to comment Share on other sites More sharing options...
ryanfels Posted August 22, 2011 Share Posted August 22, 2011 Or if you cant bring yourself to say your from there, say your from the JZX forum Quote Link to comment Share on other sites More sharing options...

Most bolt suppliers won't stock them like that. Quote Link to comment Share on other sites More sharing options...
Spencer Posted August 22, 2011 Share Posted August 22, 2011 Special price from a GC at toyota should bring the price to half that Quote Link to comment Share on other sites More sharing options...
R100 Posted August 22, 2011 Author Share Posted August 22, 2011 Just ordered a set of Toyota 4AGE ARP Flywheel Bolts M10 x 1.25 from NZ Performance $49 set of 8. They are 26mm long and mine are 21mm long. My flywheel is 13mm thick. Quote Link to comment Share on other sites More sharing options...
