The wastgate is different to the BOV fella ..

the wastegate will be internal and the BOV will be re-circ.

On the MR2, you can unbolt the stock and re-bolt an aftermarket. Most people get aftermarket hard pipes and then get BOVs welded into them.

You want the BOV as close to the Turbo as possible. and before the IC.
