ok so would it be possible to silence the external wastegate or does this defete the object. but it needs to say under 98db I'm not looking for serious power as in my opinion 200 whp and car weight @ 1000kg this would make he car both reliable and fun.

silencing a seperate EG exh is perfectly possible and common on some of the 80s serious Porsche and Audi race cars. look at using 2 stroke moped/small bike silencers as they shoudlnt be restrictive. also be sensible with the outlet. point it at the tarmac below the car and a lot of the noise is 'lost' as far as db sound meters are concerned. have it sticking out the bonnet or at the kerbside will only cause the track noise nazis to get uppity lol

dont need to think about an external wastegate at that power IMO. FAR worse issues to think about first, like management/fueling (you'll need bigger injectors) intercooler, exhaust.

A T28 from an s14 on the standard manifold should do what you're after
