what diameter is the std arb on the rear of a s2 turbo. Im sure they are 12mm. Anyone confirm. Was there only 1 size used on the s2?

 

thought it was only s2's that came with an rear arb

 

hence me asking

 

I thought they were 16mm?

 

i thought if you have a rear arb then it can only be for a s2 escort? that was my thinking

 

Orions come with a Rear ARB, XR3i's and cab's don't... I thought Orion and RST were the same but, it seems Series 1 turbos use a 12mm from an Orion, and a series 2 turbo uses a 16mm.

I would like a 16mm for my Orion!

 

bolt two together mate

 

i have a s1 but i got a s2 roll bar. Need to order bushes but will wait to get home before ordering

 

this is why im not sure

in the back of me head i keep thinking isnt it 16mm?

 

S1 = 12mm

S2 = 16mm

?

Chaffe - howd u bolt 2 together?

 

you need four clamps (two close to the body mounts and two very near the ends of the arb) and clamp them up. Clamps will have to be made either by you if your handy or by a machinist. Get four 2" long pieces of 1" square bar, drill two holes in each (same size as the arb) and one central hole for the clamp bolt, then split in half lengthways.

 

Have you tried this?
Just leaving the standard bar to body and bar to rear arm mounting points?

 

i did it on the front of an old escort once
