IMHO I wouldnt bother with the 190 pulley but would just go get a set of K series verniers and get them fitted and timed correctly … it will be the better solution
I would, if I was also fitting an Emerald, etc., but the only reason I have the ECU is that it cost me very few ����’s so having to cough up an additional �200+ for verniers, then sort the fitting & timing isn’t cost-effective.
SGT had the pulleys priced at a significant discount also, just that the parts shelf had the wrong ones on it…!
