the first smallport GZE was in an 90 series rolla chassis...
quads on the 16v ecu = rich.. crazy town rich...
can't use 20V ecu..
ecu is your choice!! many out there some better than others, i used an adaptronic on mine, suited it perfectly!! and easy to use..
with the T3 adaptor plate, it spacers the quads the same apart, so you can use the factory 20V air box.. i have one sitting there collecting dust and spiders.. run a bit of a pipe into that with a filter on the end would work perfect!
acc cable should be able to work.. the quads have the cable in the middle.. so you would just need to make a braket to pull the cable to where it needs to be..
hope what clears things up for ya..
