Shimming Wastegate

I think that joel williams way sounds good and safe. I will take shims out on my next day off. But its fun!!

i wouldnt go over 10 psi on stock ct-26, i killed 2 stock ct's doing that..
and i would not play with a boost valve untill you upgrade your boost gauge 4 sure.. nice piks on your other post.. gj and happy boosting.

Would I be safe doing this with 3 or 4 washers on a totally stock supra? This is just too good to resist, but I don't want to mess anything up.

Also what is the average price for a decent gauge? Im looking online and they seem pretty expensive (for me).

i have four shims and its a new car no problems for 600 miles or three tanks worth of fun

Shimming the wastegate is fun! And a cheap way to make power!

Thread necromancy I know but just a quick q, everyone is talking in terms of washers but has anyone ever measured the actual thickness in case someone comes across a batch of thicker washers & toasts their baby?

Also, on the subject of toasting & the question of boost spike/creep. Wouldn't 'yotas fuel cut save the motor & give a hint that something's wrong provided you took action as soon as it happened?

And I'm considering going for maybe 4/5mm worth of shimming, as from what I gather (although it's not so clear hence why I asked) that would take it from 6 to about 10/11psi?
