Length of 5cyl 20VT OEM head bolts?

[raymor]

... the reason I ask is that I want to put ARP on my 5 cyl TDI as part of preparation for an oompf increase.

Strokers use the BMW 3.5l kit, I believe. Standard AEL head bolt is M12 x 115, but EKTA doesn't seem to list the 5cyl 20VT specification. It's the length I'm after?

Any assistance gratefully received.

thanks,
Raymond

measured one for ya, it's 142 mm. Have to say it's a used one.

As it turns out, ARP have recently created a bespoke headbolt solution for VAG 4 cyl TDIs. The previous solution was based on 2l Cosworth bolts and did not appear to be well received.

...but the best bit is that the 4 pot TDI headbolts are exactly the same part PN as 5 cyl ones. Not as cheap a solution as the BMW 3.5 kit that strokers use, but it was worth a shot

are those m12 bolts 12.9 ?

Yes...
