Hello,

I'm in the middle of my non seq conversion but I guess this issue would also be of interest for people runnig stock twins.

In my particular cas I"m having my wastegate machined (to 1.24") to cope with the extra exhaust flow of the non seq setup and to minimize boost creep/spikes.

I have been using Forge Motorsport products in the past and found their adjustable wategate in their catalogue. Mainly just looking like the stock one but then adjustable. I know from previous purchases they will include extra load springs in the kit when asked for.

I see this as the stock turbo wastegate solution as single turbo's are havng an adjustable wastegate as well (though different/external setup and diameter)

Anybody tried this before or have some comments on things to look out for?

Here's my thread regarding the non seq cnversion (with pics)

Looks good ,my wastgate port is open to 1.38 inches . I have taken the stock actuator apart and changed the spring . I made a flange clamp to put it back together .This is alot of trouble so buying one that is adjustible is what I would do next time .

thx for your input. 1.38" of porting probably is pretty large. I guess you had to make the wastaegate flapperlarger as well?
