I want to put my S5 hybrid TO4B complete with standard S5 manifold on my S7 bat to replace my broken twins, then plumb it all up, run standard boost levels aound 10 psi and leave it at that what sort of problems am I likely to run in to?



Will a S5 turbo manifold fit on a S7 block and as importantly with a turbo on it in the engine bay?



I was told the standard S5 wastegate was sufficent to vent with the to4b, I've got a 3"exhaust all the way no cats or crap like that so I'm guessing the to4b is gonna want to boost well above standard psi how can I keep the boost down?



Any advice would be greatly appreciated!

Plumb a line from the pressure side of the compressor to the wastegate actuator. If the wastegate ports are big enough, it will limit boost to stock S5 levels. Higher boost can be achieved with a boost controller, which in its simplest form is just a ball-spring valve which will delay the pressure signal from getting to the wastegate actuator.



Sorry I can't help on your other questions. Anyone?

Thanks! the guy who built the turbo said it would be big enough so cool hopefully thats one problem out of the way p.s. the only reason I'm trying to go with this setup is a limited budget and I already have these parts, the turbo is brand new.

Are you speaking for experience with a series 7 or a series 6? Because I have heard that there are slight differences between the series 4,5,6 exhaust gasket and the series 7 is this true in all cases? I haven't taken it apart yet or I would find out myself.
