Here is a link to an older article that might help you out:

420A - How to build a 420a stage 2 turbo kit for under $1000

Well, I have been getting a lot of e-mails and PM's asking me for this so here it is.Basically, I've been dying to turbo my car since the day i got it. But I've always been way to poor to afford a $3000 stage 2 turbo kit. I also realized that the price you pay for the kit is a lot more then...

nobody sells anything close to a full kit that isn't chinese shit.


first off you will have to get your engine built for boost.
or at least the bottom end (pistons, rods).
The 420a has pretty weak valve springs so its best to put in stiffer ones if you plan on running enough boost for 400hp
and while your in there, might as well do turbo cams.

2nd thing, your gonna need some form of engine management so you can tune the fuel and spark. most everybody uses mega squirter (MS3)


for the turbo shit, this is most of what you need. i probably am forgetting a thing or two.

With a budget of up to 8k, it'd be better to pick up a turbo car or full swap to start with.
