The TB’s are getting old and some people seem to be concerned about linkages wearing out and having too much play in them. The play that develops in all honesty has little to no effect on the function of the TB itself.
Bearing this in mind, I’m offering to enlarge your SPARE TB, if you don’t have one, buy one that you’re happy with, for two reasons:
1) I’m doing this in my spare time and how quickly I can do them could vary so I don’t want peoples cars off the road relying on me. I will of course endeavour to finish them ASAP.
2) By not offering them on exchange basis, any play issues in the linkages are solely dependant on your TB.
What will be required is small group to send me their spare TB’s along with payment, 4 people minimum. When there’s enough interest we’ll agree a date when I should have the time to do them ASAP, (for example not before I go on holiday).
I will dismantle, machine, and reassemble your TB and return by recorded delivery. If your’s is already in pieces then send me all the bits, because the butterfly has to be aligned with the TB fully assembled.
When I've finished your throttle body I will contact you for the payment of £60 including return postage via royal mail recorded delivery and a £5 donation to the zone for each body sold.
You could then of course sell your old 60mm body to someone wishing to participate in the next batch.
This is the first body produced for a zoner, I'm machining them on a CNC lathe now and am able to profile the entry to allow better airflow.


This is what happens when you try to go above 64mm diameter.
