BDA cam carrier

Hi all,

I need a cam carrier for a BDR 1700 engine.
But at which point we need a one with 1.25" inlet tappets ?
originals BD are 1.2" on both sides, but with 1.325 inlet valve, do I need to go a a BDG one ?

surely its the cam profile and lobe size which dictates that?

For a BDR even with those inlet valves you need the normal / std BDA camcarrier.
But make sure you get a later type with has been strengthened between the front and first "bridge".

What are you going to use it for? Street? Rally? Race?

rally in demo event, to replace my cossy N/A.
I hope around 190cv with L1/L2 cam's, valves are 1.325" (33.65mm) and 1.145" (29mm), BDR 1700 head. All steel engine. long rods.

Due to valve size, I can't keep it 1600cc, I have to change my pistons by 83.5mm ones. That's a shame as I have 4 new cosworth pistons !
