Uhh, I think you're confusing the wastegate and the blow-off (compressor bypass) valve.

None of the 4-cylinder N-bodies have a MAF either (all the generations).

The best advice I can give is gather parts early. There is nothing wrong with buying all the parts even a few years in advance.

Makes the rebuild a bit easier to deal with

oh s#^t spy i completely forgot, so yes, i am a bastard for that, sorry
i still may want ur 3'' exhaust in a few weeks though
the intercooler was in a junkyard on an old Mitsubishi 3000GT, its a Blitz front mount, idk how reliable these are but it was $20 with the busted turbo so i got it...
if its busted or something is wrong with it (or it just plain sucks)...
then I WILL BUY SPY's INTERCOOLER!!!

Lol..

K. So with this setup, you're going to need a good hunk of money. Tuning is the essential part. It's somewhat hard to tune a twincharged setup, supposedly. I wouldn't think so. But I'd tell you to take it to a place that KNOWS HPTuners and let them tune it, might cost a bit. Get the GM reflash as a base, then it can be modified and tuned further for the whole setup using HPTuners. You should use 550cc RC Engineering injectors, at least. You could even put them in rather than the 310cc injectors that come with the kit right off the bat. The stock supercharger reflash is available online, and I have it (assuming you have an auto, although I'm quite sure you can flash it to a manual setup IIRC), and all you'd need to change is the injector constant, which I can give you the correct one if you're unsure. It's a simple calculation.

Then it'd run just like normal but at a far less duty cycle and with much room to grow. After you have the MP45 kit all up and running is when I'd start working on the turbocharger side of things. I don't know much about turbo naming/sizing conventions but you should be able to get away with quite a decently sized one since the supercharger will be the aiding factor in getting it spooled quickly.

3" full exhaust definitely.

Buy Spy's intercooler... Spearco units have very low pressure loss, his has well-designed end tanks, it's in great condition.. sell your other one.

GT35 should be plenty if you're not looking for more than 600+hp.

Any pics? If it's an actual Blitz intercooler (not just a generic core someone called a "Blitz") it's a pretty decent intercooler. What are the dimensions?

and parallel twin turbos both feed the same.

I know this was awhile ago...

That Maserati bi-turbo setup you're talking about is a sequential twin turbo setup, they just called it bi-turbo.

Sequential = one then the other = one turbo boosts until the other is spooled.

Twin turbo and Bi-turbo are still the same thing. There's no point in having two of the same sized turbos and having only one spool at a time.

Look at the B5 (2000-2002) Audi S4 with the 2.7L Bi-turbo engine. It's a V6 with 2 equal sized turbos each connected to it's own 3 cylinder exhaust bank.
