    Tech spec for Z20LEx manifold studs - please help

    I'm trying to source some up-rated exhaust manifold studs to replace my standard ones with. (I've done some searching on the forum but can't find anything).

    I'm in contact with a guy at an ARP supplier and he has an M8 set listed but needs to clarify some details so he's asked me:

    How long are the studs?

    What is the thread pitch?

    Please post if you know - thanks.

    (When I get a part number and a price I'll post details here for everyone's benefit).

    Sorry mate please could you expand on that a bit, is 1.25 a measurement in mm?

    What does the 25 relate to as it can't be mm as that would be too short for the entire length of the stud?

    Cheers

    sorry yeah i just copied it directly off EPC

    the 25 relates to the 1.25 bit

    not sure of length but ive got some spare studs in the garage so could measure them tomorrow if thats any use

    1.25 is the pitch expressed in mm's (this is a coarse pitch) fine pitch in an 8mm stud would be 1mm

    M8 x 1.25 x **mm (will need to measure though)

    A reply within minutes!

    I don't have a part number but the ARP kit including 10 studs and 10 nuts will cost £78.32 + vat and delivery.

    I asked if the studs and nuts were available separately but they're not.

    This is from www.arrowprecision.co.uk - really helpful so I'd have every confidence in buying from them.

    Order today for 15% VAT, last chance this year.


    Hope this helps!
