Are you talking about the turbocharged 400 cu in small block chevy that will be going into my 74 Nova Hatchback?

Here is more info (rare Martin Turbo Systems Turbocharger designed to fit under the stock hood of a 79 Vette): http://www.xsorbit4.com/users/allold...num=1092354033

or are you refering to the turbocharger setup that will be going onto the rear 3800 LN3 (vinC) in the 1994 442 project? (3800 from a 90 Toronado Trofeo)

The 3800 setup will be Fabricated by me (I have welders, a plasma cutter, drill press and more-plus access to a Bridgport Mill-and more) using the factory tube manifolds (the orig outlet cut off and welded over with a new stainless steel manifold/turbo mounting flange welded to a modified X over pipe) and from there out the turbo down pipe to exit at the LR exhaust tip (RR exhaust tip is fer the front 3100-will be a 3800 when we get another donnor vehicle)
the Mitsu TD06 turbo will be cooled by the rear engine coolant, and provided oil from the oil press port (oil return will be welded into the side of the oil pan).
then with the Compressor turbine side..... a large K&N (8 inch diax12 inch long) will feed the inlet through 3 inch tube from the drivers side of the rear engines radiator. and from the Compressor outlet to a (still working on the design-it wont be done till over the 05 winter and ready, maybe, for the 06 racing season) Heliarc welded case that will hold the Air Conditioning Evaporator (that is currently in the dash-and will be fed from the AC compressor on the front engine) for intercooling the hot compressed air and then piped to the throttle body of the 3800.
In the begining (if we havent gotten the MegaSquirt v2.2 DIY EFI by then) extra fuel enrichment will be by 1 or more SAAB (or similar) Cold start fuel injectors engaged by Hobbs switches (pressure switch-adjustable) and adjusted with a wideband O2 sensor (the MS EFI will use the exact same sensor-to help me tune the fuel maps) rich enough to prevent engine damage, this should work adequatly for 10-14 psi of boost (using a "Grainger" Boost control valve-allot of the stuff i've learned playing with my 87 Chrysler GTS 2.2L Turbo I-along with how to make your own adjustable fuel pressure regulator!). Over 10-14 psi will def require the MS EFI system with ~45 lbhr~ injectors and with the new version of MS EFI i will also be able to control a DIS ignition system and adjust the spark adv curves with it.

Is your friends 74 Nova a hatchback 2dr model? I havent seen more than 2 other 73-74'* with the hatchback What has he done to it? got a link?

I'll check out your Cardomain pages to see if you have a link there, here is the 94 442'* CarD site: http://www.cardomain.com/id/94twinengine442
I dont have one fer the Nova...yet

His is just the 2 door.....its got a 305 with a 400 crank and its bored .30 over all I know other than that is its got a tall azz K&N and headers with flowmasters (he said hes got an original DZ 302 Z28 block at home for it too )....but I was interested in what it took for the 400 SB turbo install....I dont have any links to his car as he doesnt have a cardomain or any other type of website for his ride. But if you could PM me with what it takes to turbo a SBC with a carb I would be greatly thankfull as my friend would as well.

2dr with trunk? or Hatchback? 305 with 3.75 (400) crank? you mean 350 right?
an original DZ 302! he could get some good money fer that from the right restorer!
The 400 sbc Turbocharger setup (Drawthrough/Carburated) was made around the early 1980'* for a couple of years by Martin Turbocharger systems and consists of a two piece intake with ducting for turbo suction (from the chamber under the carb) and discharge to the lower intake to the cylinders. and a new passenger ex manifold that the turbo bolts to with a x over pipe (from the drivers side stock 79 ish manifold) and a new 3.25 inch turbo downpipe to be routed to the rest of the exhaust system. the carburator was a specially modified Holley 850 cfm (holleys improved version of the GM Quadrajet) spread bore carburator. I have the whole kit-everything!-that i removed from a 79 corvette a customer wanted fixed for cheap (so i got the kit). I have seen a couple kits for sale (every now and then) on ebay for around $1000 but thay dont include the Carb and are sometimes missing parts-ALL of the other kits i have seen are of the more common RV/Truck kit with the turbo mounted up higher and twisted-I have the much rarer kit designed to fit under the factory hood of a Corvette-the truck kit would require a large hole cut in the hood (it was designed for the taller engine compartments of RV'* and trucks).
The kit is going on the 400 that will be going into my Nova (at some point in the next two years or so-i'm not skimping on parts/strength) with all forged rotating assembly (4340 crnk/H beam rods and forged pistons) at 8.5 to 1 compression at 8+ pounds of boost with a 2 stage 250Hp shot of Nitrous my current Simulation shows approx 550 ftlbs of tq at 2800 rpm and around 500Hp at 5000 rpm and with the Nitrous, approx 800+ ft lbs of tq at 2400 rpm and 800 Hp at 5200 rpm with about the flattest tq curve i've ever seen! power drops off at 5800-6000 rpm so i wont need to spend the money for lightweight valvetrain components ($$$) to let it rev to 7000+ rpm and shifting at 5800 rpm will put the engine at it'* Tq peak at approx 2400-2600 rpm.
the engine has been through several mockups/stages of assembly to make sure it all works fine but i am still saving for a few more parts (the custom cam and a few other neccesities...) before it will even be thought about starting it.
but for now we have the built 350 with new heads and a plate N2O kit fer fun. I hope to pull a low 12'* high 11'* this summer with the 350 (best so far is 13.5 at 103+ mph-with less than $3000 in the whole car)

Default update on the 442

on monday we finished putting in the (reman-90 Trofeo) axles, and some more wiring (damn snow). got to start her up check all fluids etc. we still have some more work to do and finish the rear firewall, but we got to drive her up the street-on an eyeball alignment-wet roads made fer a nice 4 wheel burnout but no smoke... still more than enough to get the adrenalin pumping
we need to re register it but all in due time (need muffler on rear engine-LOL) this next monday will hopefully be video day so ya'll can hear this bad boy and see it in action (hoping fer decent weather)
here are some new pics:

just do like the twin engine Tiburon did in the WFSC shootout, put one tranny in drive and the other in reverse, just make sure you got plenty of parking lot and extra money for tires cause I can almost guarantee one of the best smoke shows (or at least most entertaining) you will see in a while
