I was just wondering if anyone can help me figure out exactly what parts I need to make my 420a a turbo. I want to put a t-25 or 14b on it. I know I can go to midas and get the custom piping but what other parts am I going to need, if any, besides piping, turbo, intercooler, BOV. How can I get a custom exhaust manifold? Do I need a custom downpipe also? As far as I know I don't have to upgrade any internals or my fuel pump, right? I didn't want to spend over $2000 for the hahns kit or the star. I just wanted a custom job that was relatively inexpensive because I can just piece this together and install my self. Also is this install hard and if anyone has instructions that would be awesome too. Thanks

dude, do you know how many people ask this question? search

you do need a fuel upgrade and YES you will need a custom down pipe. search for everything else. its probably in the "things we've seen before" section

Also needs fuel pump, FPR, Hoses, oil return lines and fittings, bov, fuel cut defencer, wastegate and the manifold and downpipe.

it will be a hell of a lot easier if you just buy a kit, not to mention it does not come out to being much more after you buy the turbo make a custom exhaust manifold, get all the piping done, ic, oil sending unit and line and an fittings, vacuum lines, fMU or FPR, fuel pump, bov, down pipe, boost gauge, etc...

If you are a real do-it-yourself type of person, Give "Turbo City" (turbocity.com) a call, my first 2 turbo'd cars were inspired from the guys there, and they have almost everything you will need except the more exotic parts such as IC's and BOV's (they carry stock bypass valves that they will help you fabricate using flange kits).
However i didn't bother asking them what i can do when i got my eclipse a few months back I just called on the "kits."
Well good luck with your trek....

i have the HRC pull lists scanned @ my site: http://www.asog.net/phantom

that may help you to get everything needed, like all the fittings and less than obvious parts and such
