take x amount of washers (usually3-4) and put them on between the 2 bolts and the wastegate plate thing and your done. the benefits of this are your turbo will put out more boost meaning u get more power... dont put 2 many washers on at once or u may wreck somthing. A disadvantage would be the argued wastegate wearing out faster resulting in turbo failure.
Check http://supras.nl/ click on the modifications section, it shows how to do the shimmy. 88 is right it may cause turbo failure, especially if you have a manifold leak, take it from me!!not good!!
LOL.......I put in 4 washers to start with and let the car warm up to get everything warmed and lubed. took it out for a spin and floored the shit out of my car and sent the stock boost needle way off the gauge and put my check engine light on..........lol it was fun as shit but a little too much. Anyway I would start with 2 or something and go from there.
i ran two shims(8psi). its works fine but i think is worth the $15 for an mbc, they do the same thing. mbc's are adjustable whereas the shims you have to do some digging to add/remove boost. also with an mbc there is not way the wastegate could wear out.
