1. Take off the turbine housing.
2. Find a ~35mm washer.
3. Remove the back plate on the turbine housing.
4. Use a die grinder (or something of similar capabilities) and enlarge the hole to a simliar size as the washer.
5. Weld the washer onto the wastegate arm.
6. Re-assemble.
So you removed your twin scroll? That shouldn't have an effect on the boost creep, I'm not sure why you are mentioning it?

Dude.... Its pointless to ask questions on this forum because everyone would rather insult your intelligence than help you.
Id check FC3Spro.com.... He has a pretty sweet site that can help you out with a lot of common problems RX7's have.
