I used a kit from that guy in Washington State to overhaul my turbo charger, I was certain it'd be too complex but everyone said it's simple and it is ~ the more odd shaped or short wrenches you have the easier it'll be .

I'm eventually going to overhaul another using the same kits but 1/5th the price from Pop Shop....

Before you delete the EGR piping and switches, get the engine hot and idling and apply strong vacuum to the EGR valve proper ~ unless it makes the idle bad or stalls the engine, the EGR valve isn't working, find out why not (usually 1/2 way open & stuck with goo), fix it (again easy-peasy to remove and clean well then loosen the 10MM ATF nut and run in the adjusting screw until you can't blow through it) , re install and delete all those pesky, leaky rocker box valves and pipes, you'll love how much better the car runs and the tranny shifts .

True European spec cars don't have all that crap .
