I was wondering has anyone done this, if so were there any gains. I know you would need the TB adapter but someone told me you get like 10-20 up increase


anybody heard of this stuff?
 


you wont gain any power from it. its just not made of plastic anymore so you dont have to worry about blowing it up, cracking it, etc.

The other difference is the inlet is longer on the L27 and is round and moves to a D-shape, while the L36 is a butterfly shape (same as L36 TB out) and has a divider in the path.

I did the conversion last month, but can't say if I had any gain from it since I also ported my LIM at the same time.


Agrazela did some testing on this issue and he saw gains in "calculated VE".

Holy crap a topswap looks easier than that write up...
 
All that is actually required is a tap, 2 hose barbs, a plug or 3 if you need to block the coolant, a short bit of hose for pvc, the upper gasket, and an adapter plate.

The hardest part was actually getting the adapter plate drilled out, but if you have a drill press that will be no problem.

The write up goes a bit in to detail and was wrote as he did it.
