    I remember when I looked into fitting throttle bodies to my engine.

    All I will say is that Pound Sterling V's BHP just doesn't make it a worthwhile investment in my opinion. The kits that are available aren't cheap and give very small BHP gains. It was a long time ago that I looked into it

    If anyone was dead set on doing this Alpina527 had much more of a go at this than I did and would have more info about the fitting problems. I just had a quick look to see if they'd bolt on whilst fitting my LPG conversion.

    I also know what you mean about the kits, the diblias kits for the M42 were about £2k. My brother managed to fit tb's to his M42. The wild cams that went with them cost a bit... I think they were around £500 each.

    I agree with there being much more efficient ways of making more power.

    As Ian has already stated, I tried converting a set onto an M52 engine but gave up in the end.

    I am not saying it's impossible, but it's far from easy.

    The ports are a different shape. Stud spacing is different. The Injector angle is wrong, and the oil filter is in the way.

    I was trying to make a properly engineered solution with the correct dowels and seals etc in place which took months of design and effort. I got it bolted up to a spare head with a very complicated adapter plate with the correct transition between port shapes, but the injector angle was totally wrong.

    If you really want the itb's, get the Dbilas conversion. It's far easier and will perform better.
