I understand that the injector relays need to be used through the loom and powered, though does the fuel pump need to be as well, or can it be wired in seperately from the commodore loom?

Here's a thread on Calais Turbo that may be of interest to you http://www.calaisturbo.com.au/showthread.php?t=192333

Thanks MAGP, but the link doesn't work

looks like the website is down

Good thing I put it in a word doc then hey, check the attachment.

The ecu switches the fuel pump via a relay, how you wire it is up to you. You should let the ecu control it because it'll stop the pump if the engine stops which among other things a safety feature in an accident.

Hi everyone,
It's been a long time since I've done anything to the old girl as life got in the way for a bit there, but it's in my new workshop and getting some much needed attention!
I have spent the last week re-making the engine mounts, changing the chassis and altering a whole heap of stuff on the car as I was never happy with it the first time around!
I'll post up pics if anyone wants to see them?
So by tonight I will be back to where I left off last time and I have since decided to get rid of the factory banana manifold from the 5L and instead run with an Edelbrock Victor Junior Manifold and 4bbl throttle body.
As I'm sure some of you are aware, this is my first time mucking around with fuel injection so, I have no idea what I'm doing.
One question I have is, what throttle body would be suitable?
Remembering this is somewhat of a budget build so don't want to spend heaps on one. What do I need to look for in terms of TPS and idle etc on it that will be compatible with the Delco ECU?
Also, I'm not sure if anyone would know if the factory fuel lines will be able to be used along with the factory fuel pressure regulator?

Any assistance would be greatly appreciated.
I'll hopefully be placing an order in the next couple of days!

Cheers...
Matt

Why complicate things. I am sure the std 5L will have more than enough power for the old landy. Going TBI means a lot more work in my books. There are just as many sensors needed and the same amount if wiring so at this stage I would stick with all the std delco system. At least then when you turn the key it's likely to go and run properly.

It's more to do with the location of the accell linkages and keeping it look somewhat old school etc.
Going with the different manifold will mean I don't need to run intake pipes and modified linkages etc.
I've worked out that changing it is the best way in the long run, plus the engine will run and breathe better making use of the big cam etc...

Yea he doesn’t have much space we can always use an old holley carb and get their gm tps kit cut out and block up holes in the carb and turn it into a throttle body and use a remote mounted iac
