removing 20v ram tubes

yeh, Silvertop was right..
Thanks anyway Mr Revhead

Well, i wanting to know cos I got a trottle body off a silvertop and just wanted to check if it is the facelift item as i suspect it to be.
I measured it and it is 47mm and i hear the silvertop are only 45mm? but the butterfly itself is 45mm I think.. not 100% sure cos can't really measure it. At the top of the qaud trottle, it got 2 lever thing so I guess it must be silvertop since i heard that the blacktop item only have 1 lever at the top.
I brought a custom made manifold for 16v engine and they are to fit the silvertop quad trottle and i noticed a very minor problem are the hole on the custom manifold are exact size(45mm) as the quad trottle and also with human error, when fitted on, it line up 98% well only suppost to 100%... so, I just need to do abit of porting myself on the custom manifold to make them line up well, and make the air flow smoothly by making the hole abit bigger on the manifold.
the stuff they sell at $2 shop are pretty good.. the grinding stone works well!.. better than a file which will take me forever to do them all
just brought another pack today as the 1st pack only did 3 1/2 holes before all the stone worn out

Hmmm so if the facelift manifold flows more.

How hard is it to change from a prefacelift manifold to a facelift one is this an easy change direct unbolt and bolt on or will it need some kind of modification. Also will this affect anything else like how the computer runs etc.
