100kw ECU running a 20v

Hi,
I am a tight ass uni student again and can not afford to rebuild my GTI 100kw 4age. Has anyone run a 20v on a 100kw ECU and if so how well did it work?
My other question is has anyone put a 16v head onto a 20v bottom end without adjusting the 20v pistons, does this work?

just realised what i said. I meant to also say that i would replace the quads for the std 100kw plenum and throttle body (realising that i wll have to adapt it)

i can't see it working without a whole lot of hassle. The 100kw ECU can't work the VVT for one thing.

couple of things -
1. You cant 'adjust' pistons as such
2. As said - why the hell would you want to strip a 20v 4age to put a 16v 4age head on? unless ur planning on massive n/a work to go over 220-230hp - i would definitely not recommend it
as for the original question, you CAN technically run the 16v computer but you will run into problems - ignition timing is slightly different plus fuel maps would be more aggresive for the 20v so you MAY run the risk (slightly) of running lean if u do a bit more work to the 20v (ie CAI, exhaust, timing etc)
i personally wouldnt do it -

the 100kw manifold and the 20V one are a very different shape so it might be pretty hard to adapt

Think about it this way.
20v with 40 to 80k on it which you can pick up for $600 or less.
New pistons about $500 if lucky.
20v-- sell quads $200, sell Head $150. keep the rest. As long as the valves clear the pistons who cares for an engine i drive on the street. the performance loss if any (because my current engine is old and probably not 100kw) would probably not be noticed, it is not a track car where i am trying to squeeze the last hp out of it.
