[Turbo67camaro]

I'm finishing a turbo charged 67 camaro that I started and sidelined about 10+ years ago.

I trying to determine how well all the turbo and fuel induction parts will work together that I had purchased years ago. I'd rather not rebuy a whole new turbo kit and fuel induction system, but I will if this setup is likely to perform poorly.

Here is what I have. Some info is a little sketchy as I'm going from memory (still looking for some paperwork):

• Motor built by Ed Hale Automotive in San Diego, CA
• 327 SBC bored ~.030 over with forged turbo pistons ~8.5ish:1
• Original 327 forged steel crank
• 2 bolt studded mains
• Eagle forged rods that can handle 1000hp
• Bottom end blueprinted/balanced
• Original cast iron heads with hardened valve inserts, stainless valves (oversize if I recall), heavy duty pushrods, 1.6:1 roller rockers, heavy duty valve springs
• Isky Turbo profile 201-TA cam and hydraulic lifters
• Dual roller timing chain
• High volume oil pump
• 7 quart Moroso oil pan w/ sump and windage tray
• Weiand aluminum manifold port matched to heads

I'm planning on selling my fully rebuilt Muncie M20 and installing a TKO-600.



Here's the parts I'm worried about working well as a system.

• Rajay single turbo 3AA1EE90B1 in pristine condition, barely used.
• Cast iron manifolds. One w/ turbo mount flange. Port matched to heads.
• Cross over pipe that routes behind the oil pan.
• Turbo City #970-101 modified TBI fuel injection kit w/:
  • 2" TBI unit with 68 lb injectors
  • computer (Delco electronics) Vin 20K w/ custom chip and custom programmed for my motor (SVC # 01227747)
  • wiring harness w/ lots of sensors
• AC Delco early 90's electronic distributor recommended for the TBI system.
• Draw through adapter that sits under the throttle body.
• Deltagate Wastegate #10101-7FF125 7-9 psi
• Mallory fuel pressure regulator # 4309 3-12psi

Some of the parts I don't have yet:

• Boost control regulator
• fuel pump(s)
• Bypass valve
• Wideband O2
• Gauges
• Intercooler

I'd like to make about 550hp at the crank with tolerable turbo lag.

Any comments on how well the turbo and fuel system is likely to work ?

The TBI system is advertised as limited to about 400hp. Does that sound accurate and is that likely a airflow / CFM limitation in the TBI that is not upgradeable ?

Should I convert to a plenum blow through ? I assume this would be inexpensive and would cut down on turbo lag and fuel atomization issues.

Should I bite the bullet and go with a STS turbo kit or other moderately priced turbo kit ?

I have a Camaro 12-bolt rear with 3:42 gears. If I recall the differential is a GM one. The housing was straightened and the welds were beefed up.

==> UPDATE -> selling the TBI kit and purchasing a MPI kit. Also, likely to upgrade the turbo to a more modern one, using blow through instead of draw through, and
