New and improved with 95% less carburetor!

[lesingepsycho]

I got the car started tonight on the fuel injection!! WOOO HOOO.

Of course the HIF44 carb body is the throttle body, hence the extra 5%.

It only barely runs since I still have to find a better place to hook up the MAP sensor - I think I have it hooked to a ported vacuum source right now - also the fuel maps aren't anywhere even close and I'm just running on the narrowband at the moment. Also, disregard the wire nuts in the picture. those are just temporary.

Once I get a wideband and do some tuning,

Wow, I can't explain the relief and excitement when that EFI fired up right away! :banana: :banana: :banana:

It's a long road ahead but this was another important step on the journey!

I would like to see a side shot of this set up. Wish I were still in Washington, I would have taken a weekend ride and look at it in person.Looks great.

Breaking new ground with sucess....Great

Cool, the rest of the road isn't as long as you think. My buddy did his Z and says it aint that bad.

What controller?

 

[tdskip]

Very cool - sorry if I missed this but what are the specs?

:drooling: :thumbsup:

 

[lesingepsycho]

Thanks for all the encouragment everybody!

The EFI specs are: MG Metro Turbo HIF44 carburetor body with throttle body adapter and throttle position sensor/adapter made by Rick Patton, Rochester 5235277 GM mini TBI injector, Megasquirt II v3.0 with spark control (made by me

), Ford EDIS ignition, 36-1 crank trigger with Magneti Marelli VR sensor.

I'll try to get some better/more pics once I get the wires all cleaned up.

So you are using throttle body injection and a wet manifold?

 

[lesingepsycho]

Hey Tom,

It is a throttle body injection and wet manifold system. I took some more pictures tonight after I soldered up all the connections, shrink tubed and wrapped everything.

The pics are attached. In them you can see the tps adapter, throttle body adapter, and if you take a close look, you'll see the intake air temp sensor threaded in where the stock "blow off valve" would be on the turbo set up. When I add the turbo I plan on adding a good quality aftermarket blow off anyway. The original was just a cork plug on a spring... SERIOUSLY!

Also, the plenum is upside down but I'm going to have to re-plumb the turbo anyways, most likely with an intercooler.

And finally, a shot from the top.

Cool! I guess the large aluminum object with the two bolts placed where the air usually makes it's entrance is part of the turbo set-up?

 

[lesingepsycho]

Tom - Yeah, that aluminum piece is the "plenum" for the turbocharger. I've got it turned upside down since I'm going to route the intercooler piping differently (they weren't originally equiped with an intercooler ). This plenum originally housed the stock "Cork-on-a-spring" blow-off valve that I mentioned earlier. That's where I threaded in the other sensor.

Here's a pic of someone else who turned the plenum upside-down. This is where I got the idea, although they aren't using an intercooler.

Flux capacitor.

 

[Morris]

Jack... you are my hero.

 

[lesingepsycho]

Wow! Thanks Morris. That's a huge compliment. Now I hope that I can live up to it! :wink: Sure everything is bolted up and pretty but the car isn't even truly running at this point. And there are still some definite unknowns when it comes time to fabricate an exhaust manifold for the turbo.

On the other hand, my wideband is on its way but it won't be here until Tuesday so this weekend I'll have to be content to do some suspension work. It's killin' me too because we actually have some nice weather here in the PacNW and I would love to be tuning on this motor, but oh well. I got all new poly for the rear end. It's pretty ugly back there and I should have done this a long time ago. I've known forever that they were bad because the back end wanted to step out if I hit a bump in a corner but I never really noticed how bad the bushings were until I was pulling the gas tank to do the return line fitting. Maybe I'll try to snap some pics there while I'm under.

Anyhow, thanks to everyone for the compliments and encouragments. Believe me, there have been a lot of bumps along the way just to get to this point and having the kind words from everyone here always makes it easier to tackle that next step! :thumbsup:

Cheers!
