52mm Throttle body, Burlen VS used MG part? (5 replies)

Does anyone have any experience with the alloy throttle bodies? I have a Cooper S touring and this is one of the last bolt on tubing options left. A quick look on eBay reveals used MG parts are available for about Â£50 which is a bit better than Â£165 for the Burlen part and the only difference appears to be the throttle linkage, can the mini specific parts be transferred into the alloy body? Any help appreciated Ben
whats the ebay number and the Burlens part number ? Roland

I meant to reply to this thread a little while ago but never got around to it!
In my experience the 52mm TB isn't worth buying unless you need to exchange the one you have (cracked for example). When I fitted the big valve head to my MPi I fitted the 52mm TB. When it was on the rolling road the guy put a restrictor into the TB to simulate a smaller aperture. This made no difference to the power - the reason being the injectors can only deliver a certain amount of fuel in the time it has available. The engine can't use the additional air flow to create more power with the injectors as they are.
As it is, the engine was running 'a little economically', as the rolling road guy put it, above 4000rpm.
Cheers, I think I'll stick with the standard one for now then. I'll just make sure the throttle stop is removed although I believe that was part of the cooper garages conversion.
