Coxy - don't talk about "social economic climate". The more I look at theese fantastic prices, the more I think, economic of britain is holding on overpriced labour and huge taxes... In case of cars that isn't brand new, I think, latvian with avarage salary can do as much as british with it's avarage salary, if not more - and not only because labour is cheaper, but also because it's repaired in more practical way. Ok, unfortunately, theese repair shops, where u are paying for time, when some guy is not only repairing, but also smoking and doing other things, and also where u can't see how big hammers are used on your car
are also spreading - at last in our capital. And again about that "social economic climate" - why there is ppls who are complaining, that B3/B4 heater's matrix change costs 300-400 pounds or C4q fuel tank replacement costs 800 pounds? Because car isn't that worth?
If I would like to have stock 3A, I would certainly get RHD donor car - because of price, very low and real mileages and also there is so many RHD cars going for scrap here.
Whatever.
About topic - there isn't any measurements - if place around butterflies isn't changed, it's only waste of money. If it's wider [and butterflies are closing at slightly differend angle], maybe...
P.S. The only way how this throttle body differs from 3A throttle body, is - 3A have iddle and full throttle switches, and not potentiometer
Now I know why 3A reacts sharper on accelerator than NG - I presume there is identical throttle body
P.P.S. Don't forget about placebo effect
