Thank you. I may have it running in a couple of days...

Just spent the better part of 2 days figuring out why the A/C system won't hold a charge.

Many thanks to RWDPLZ for his information here:
http://www.fiero.nl/forum/Forum2/HTML/000652.html

Half my O-rings were the wrong type and I DO remember the guy at the A/C shop matching them up saying
"these are a little thinner, but they should still seal fine." NOT!! What a lot of grief it has caused.

I've run the system to a vacuum of 20 lbs. It's still holding 1/2 hour later so far...

Looks amazing. I cant wait to see it in person.

It's up and running. Yay! - no oil leaks anywhere
(new rear main seal, axle seals, transmission halves joint, oil pan gasket)

The clutch and FWD Getrag transmission are working great too.
It's getting better as it 'breaks in' - the Getrag was tight and notchy at first because it is NEW.

I noticed a side benefit of the FWD Getrag is shorter shift throws.
This is likely a result of the transmission's shorter shift shaft that Rodney's kit bolts on to.

I always had problems with the A/C after converting to R134a.
(new compressor, O-rings, orifice, accumulator etc.)
The A/C worked great, but the charge wouldn't last more than a week.

When I dropped the cradle to replace the clutch and transmission,
I found a cracked A/C hose tube at the compressor end. Got that welded.
I also installed a new condenser I had bought a couple of years ago.
And I replaced all the O-rings in the system with the correct ones this time.

It's now working and is blowing SO cold with R152a that it can freeze you out of the car…
It appears I have finally fixed ALL the leaks once and for all.

Bump! Any updates?

Your build makes me really want an SD4 for my Indy.

Working on a MPFI system using the Edelbrock 2-bbl intake.
The manifold was designed for mechanical fuel injection nozzles.
Luckily the bosses are beefy enough to be drilled for electronic injectors.

Edit: added this pic I found online



Here's a mockup of the fuel rail using plastic tube. Have to duplicate it with aluminum.

2-bbl throttle body is from a Dodge 3.9L V6 - twin 42mm bores.
The nice part is the TB topend fits a 4-bbl air cleaner - so my carb bonnet fits.



I did an Autocad drawing for the carb intake manifold-to-Throttle Body adapter and had it water-jetted.
The adapter bolts to the manifold. Then the Throttle Body bolts to the adapter.



The injector nozzles are dead center where they should be.




Manifold was drilled using a ShopSmith. We started with the center ones.



They were easy. The end ones have 2 angles to get right.




Injectors are tiny Bosch EV14 injectors with extension.
48lb Bosch part number 0 280 158 211
Bosch debuted this size injector in 2012, and without them I couldn't build this system.





Spray pattern of these Bosch injectors.

Will you need a new fuel pump for those injectors?
What ECU / how are you going to tune ?

Same pump, same 1227165 ECM I have in the car right now running the FAST throttle body injection (at 43psi)
