Steel weighted type 4 pulley

That, I believe, is why the clutch was knackered in my Japanese import when I got it!

You can almost guarantee it

Anyone running a ahnendorp pulley?(145mm) CSP?(I think is 125mm) is that too small?
LAperformance has a 135mm ??

To return to the original question for a moment.....

For upright cooling (T1 fan?) can you not use an alloy T1 pulley but with the centre machined for the T4 fan hub. Is this not the DIY way?

If so, could you not use a steel Berg pulley rather than a cheap alloy T1 pulley?

Although I'm not aware on how the Cali conversion deals with it(it uses a machined out type 1 lower pulley-right?)the CSP conversion uses an 90mm top pulley to get more offset for the lower pulley.I bought the top pulley from CSP and machined the lower one myself because I wanted it in steel and smaller(in diameter).The CSP top pulley messes with the drive ratio,it makes the fan spin too fast(stock 1600 is 105mm,CSP top pulley 90mm).

Re: the top pulley.

I've seen one cali conversion where the (stock) top pulley is reversed to get the correct offset. By using a non oem top pulley the spot welded centre can be removed and welded to the other half, so reversing the pulley.

It does mean the belt doesn't align with the alt bearing tho.
