i have a renny turbo and run a t28 as the t3 was a pain to fit. does the frst use a 5 bolt hole flange on the back of the turbo or the triangle 3 bolt hole like the escort? t28 gives me 185bhp with hardly any lag off a rover 220 turbo. a 200sx,pulsar use t28 as well i dunno about the config for exhausts. all i know is the tuners try and sell my turbo as a hybrid and charge a lot more money. same as t3 hybrid for escort uses mg maestro exhaust housing and cossie 2wd front with a bit of machining to front housing. all the best max
