Hi and welcome to the forum. The main pump adjustments are covered in the link below in good detail. It is from a dodge cummins diesel site but the pump is the same and the writeup is good. Read the link below on runaway first.

Take a look at some of the threads on turbo combinations. If you really want to up the power I would get rid of the stock turbo, the compressor side isn't all that efficient and the exhaust side has a restrictive design as well. Adding an intercooler should also be near the top of your to do list. Depending on how far you want to go, next would be head studs so you can really turn up the boost. With a better turbo, intercooler, and correct pump timing you can push an easy 15lbs of boost with the intercooler and the car will be pretty fast.

Check your injection timing as well (not detailed in the cummins write ups) and time it towards the top of the spectrum or maybe a little higher. I would shoot for .90 to 1.0mm.

With a larger turbo I would step up the downpipe as well, to 2.5". The factory air filter is good size, but you can open the box up a bit by removing the intake baffle that goes into the fender, and "swiss cheesing" the front of the box behind the headlight for more air flow potential.

There are a few places that sell shocks/springs/sway bars, I think IPD is one of them, and there may be others, I haven't really looked into that stuff yet. If no one else chimes in check over at turbobricks.com, there is alot of good info over there and most of those guys have lots of mods to their cars.

Biggest turbo you can fit would be what I did, the T3-T4. While you could fit a bigger if you cut into the frame, a T3-T4 has more potential than our engine can use. Check over on the turbo thread for more info on the sizes and such, I don't want to retype all of it. Only thing I would recomend is a smaller exhaust housing than I used if you went with the hybrid. I would go with a .48 A/R for better all around performance and good spool up at lower RPM. My turbo is a chinese knock off turbo from ebay (though I made it out of a few different turbo pieces I had laying around). All of them I have seen have the larger .63 A/R exhaust housing which like I said is a little large. You will have to modify the oil inlet and modify the waste gate canister to fit as its pretty tight. I have pictures over on that thread.

When you say a T3/T4 has more potential than our engines can use, what exactly is the limiting factor for the engine? Is it fuel delivery?
