Cant find any threads on this, anyone?

for the turbo,you need to drill a small hole on the cold side and make a nipple.
For the maf you need to remap once you have done that as the car wont really work and also fabricate a way for the maf to stay in position as it will be easily blown off due to pressure.

You will also need to fill the electrical area (under the cover) with epoxy resin as its not air tight under boost.

If you decide to put the MAF mechanism into a metal tube you must use the same diameter as the original or it will not be mappable.

I was thinking about fixing the maf in2 a metal tube thus replacing the plastic caseing, has this been done, also the vacum hose 2 the nipple on the front of turbo wat exactly does this control and can it b done away with,or changed,thanks for replys guys

It may be possible to place the nipple to some place after the turbine? maybe to the maf housing in this case? should work..

Re metal MAF tube read my post above ^^

Nipple on turbo is the feed to open the wastegate, you need that Just drill and tap it.

the nipple on the turbo cold side is best to be situated as close to the beginning of the cold side as possible.If placed after the turbo or at the end you may have problems with mapping(nothing serious,its is just how well it reads the pressure built from the turbo.thats all)
