I have three. Aftermarket boost controllers are ten-a-penny and most decent aftermarket ECUs support active boost control anyway. :-) #2727 has an pair of Island manifolds hooked up to a Z7U, aftermarket ECU and the turbos are Mazda 323 type IHI RHB52's. It's hitting the ECUs boost safety cut at 3500rpm through a crappy intercooler which will be changed out shortly :-) Martin [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
