Okay, okay, so far as i know the units are a stage 3 replacement for the (standard)CT-20 turbos. The models are MD-315 with the following upgrades:
1, Ported wastegate
2, Uprated large poppet valve
3, Twin seal turbine modification
4, Cut back turbine blades
5, Uprated actuators
6, Modified compressor inlet duct
I mentioned that i wanted solid turbos as a basis while still looking pretty much stock under the bonnet(at a glance ) and know i won't achieve much more than 500BHP but i want to see how far i can take the mod' as i don't want to go single yet.
I have owned my supe for less than a year yet, so i'm just playing at the moment...
All i need to know is if anybody has done this mod' and achieved better than expected results ie with an aftermarket manifold.
Thanks for the responses
