i think only the 48mm has the wedge on the butterfly, so no wedge and alloy means a 52mm TB

Only just read this thread - I also 'flowed' a 48 alloy TB last year. You can read all about it here . It certainly hasn't harmed the performance as I confirmed at the Silverstone track day!

At long last: the time, weather and inclination to dismantle all that felt and stuff and replace the 48mm body with a 52mm one. Hardest part? Working out in a non-destructive way how the non-jubilee jubilee clip holding the feed hose to the throttle body actually works.

Oh yes, discovering that I didn't have an 8mm socket and the quick trip to the motor factors to remedy that want.

Thanks for the "how to" forum.

Has the 52mm throttle body made much of a difference as i only have a standard 1.8 cc and would like a little more get up and go

The larger throttle body will help but you really want to get more air in in the first place. The most cost effective bang for your money is to fit a K&N 57i cone filter, See this thread on the T-Bar

:woohoo:

I'd say that I can detect a difference. I wouldn't say it's gone all v8 on me but I'd say revs pick up more quickly low and mid-range.

Next job will be to take the air intake to the nearside wing, then a TT exhaust and then a remap.

Does the 56mm throttle body fit the F or was this just a ZR throttle on a vvc

You'd have to compare the mounts but quite possibly so. I'm going out now but could measure the spacing of the bolt holes if you like...
