So turns out that the port on the IM is the same size as the TB. Guess that the IM must have had a step up in size, which I think is supposed to be a benefit - oh well.

Car's at the garage today for something that I've been meaning to get done for ages - getting the intake mani ported to match the dc2 throttle body. I don't know if it really needs it, but although the bigger throttle body made a nice difference to throttle response and acceleration generally, I had a nagging feeling that it was struggling at higher revs after the butterflies opened, compared to before (or compared to lower in the rev range anyway), and figured that it was because there was a step that the air was having to force past. Might make loads of difference or none... Who knows It's at AK Automotive, which is the place that do loads of mx5 stuff and have a race team. When I dropped the car off yesterday, I had to laugh at this sticker on the back of this track mx5
