STS has a great site. From that sites FAQ, however, I must agree with Al Hounos about the slightly smaller turbo being a better choice. At least a turbo with a smallish hotside.
Agree that "lag by filling the I/C pipes" is b.s.
Bottom line: If it's different but works (a la Turbo Tim or, say, a twin charged..) people will give props, and it will be "cool." heh.
Doesn't heat create the velocity in the exhaust gasses to spool the turbo?
No, heat doesn't create velocity. Heat creates volume. If you look at any of the physics laws for gasses, you will find that pressure and volume and heat are related. PV=NRT is a popular one, The V isn't for velocity, it is for Volume.
The turbine housing is what creates the velocity. The scrolling design that reduces the volume of the exhaust chamber as it scrolls around causes the gasses to have to increase in velocity and pressure to maintain the same flow rate.

I'm stoked you're doing it. Nobody's pissed. I've only read about the v-8 kits, but from that info I say it'll work.

I am very interested in your progress. I am seriously considering a similar kit for my brother's saturn.

yeah very similar,
basically a aluminum catch can could work, drilled out to 1/2" you could use a small section of thread pipe to the return fitting, and screwed directly into the catch. then the pump can scavenge off that. that way the turbo won't backup and the pump shouldn't run dry. plus you keep everything as far from the ground as possible. then the return line can go up, down, every which way.

one of the nice things about this setup is that i can swap turbo's with very little modifications, only the flange needs to be changed to mate the turbo to the exhaust. ALL of the other plumbing remains the same. once the system is installed, i could change turbos in less than five minutes. (remove from hangers and unbolt the exhaust flange and loosen the intake charge pipe silicone adapters.) here are some pics of the car...

I think with an .48 exhaust housing, and a reasonable compressor you'll be fine... I'd expect full boost a few hundred RPM later than a typical setup so probably around 12psi@4500 rpm. You will probably see positive pressure around 2600 rpm. This is obviously a guess, so take it with a grain of salt.

olderguy, i don't. the whole car is a pigsty. halfassed ideas and uncompleted concepts riddle the vehicle. if i ever win powerball, i'll pay someone to hire a top of the line machine shop to realize all of my hairbrained schemes, but for the time being, it's just me and my duct tape. and if something gets too dirty, i just chuck it and start over. (soapy water)
arkmage, very very good guess, i would probably postulate the same numbers:
out of vacuum at around 2,500 - 3,000
boost to start after 3k, real boost (2-3psi) around 3,500 - 3,900
and then it should hit hard (6psi+) after 4,500
and like you, these are guesstimates, with a truckload of salt.
fmowry, you give me too much credit, i've got no skills, just dogged determination, for better or worse. as for swapping out turbos, you're right. i am starting with the smallest chinese turbine i can get (not too worried about the compressor side, as i am more concerned with spool than with charge at this time), and cost is most assuredly the main consideration, but truth be told, i do like the idea of being able to step up from one turbo to another with very little hassle. i am not trying to change anyones perspective on what is "BETTER", - that concept is purely subjective, all i want to know is whether or not a 1.6 stock motor has enough exhaust to push a small remote system. STS has proven that the concept works and is viable for large cube engines. i want to see if a tiny motor can do it too! believe me --> if this system doesn't pan out, i'll gladly take the hit and wave off anyone else from doing the same mistake, and then meekishly get in line and get a BEGi.
