12.9 M20B25 head bolts *** group buy ***

[e30_Turbo]

As there are more of us around now I though it would be a good idea to get a group by sorted.

The bolts are 12.9 grade and the usual socket cap end type.

I have them fitted to mine and torqued to 80ftlb's which is nearly three times the stock pressure, they are also non strecth so are reusable.

14 bolts work out at Ԛ£4.50 each or Ԛ£63.

More people = less cost.

List:

1. Ant

11.

I'm also gonna contact some head gasket suppliers as there may be a need for some of these too.

Ben, yours are on their way to your secret e30 high power turbo testing facility in Kent, the technician will, at your request, insert them in your holes and tightening as needed

Good luck dude! I'll be down soon to take a peek
