EricB Posted November 8, 2003 Share #1 Posted November 8, 2003 The original matching # L24 kicked the can yesterday afternoon. As a result I am putting in my F54 which has been waiting in the wings for some time, that and some brand new Mikuni 44s... yum!Head bolt torque specs for an L24 head with the F54 block?Or are they not different than a normal L24 torque spec?Which Z should I get the head bolts from?I've got a 77-8 5spd in there right now, when I go to get new clutch/press.plate am I asking for one intended for a 77-8 280Z?Or am I asking for one for an '81 280ZX?Should I keep my current flywheel or use the F54's flywheel?Does it matter?I think I've got everything else covered...-e Link to comment Share on other sites More sharing options...
Ed Posted November 10, 2003 Share #2 Posted November 10, 2003 I believe all head bolts are the same from 70-78. I would suggest spending some extra bucks and getting the ARP bolts. You will be increasing the compression with the flat top pistons in the F54 and the extra bit of insurance will make it bulletproof. I've heard the turbo bolts are pretty good too. Torque specs for stock bolts should be the same. Torque specs for the ARP bolts are different.When I updated to my 5sp I went with the 81 clutch and pressure plate it looked like it was bigger/beefier with more surface area. I think they all bolt in the same. Link to comment Share on other sites More sharing options...
EricB Posted November 10, 2003 Author Share #3 Posted November 10, 2003 I did get an 81 clutch and pressure plate to go with the 81 flywheel but it seems (seems being the key word) that the pilot bearing I was given is slightly too big to fit inside of the crank... I'll have to look at that again in the AM....-e Link to comment Share on other sites More sharing options...

Ed Posted November 12, 2003 Share #5 Posted November 12, 2003 The ARP (Automotive Racing Products) bolts are high grade/high strength bolts. Stronger than the stock bolts. Although we are probably overdoing it on a street engine. But if you have ever seen an engine after an old rod bolt goes bad:disappoin :dead: .Atleast as a minimum on any rebuild use NEW rod bolts. The ARP bolts will let you feel a little better inside when you hold that gas pedal down and the engine is pushing 6K.You could order them through any automotive store, part #202-6003 which are for the L24-L28 series. VB and MSA sells them. Link to comment Share on other sites More sharing options...
