Can the EFI throttle body and injectors and associated parts off a holden 3800 V6 be used for injection on a vw bug engine. i have the coil packs
too.
be a shame for these to go to waste.
and has anyone used these items at all.
cheers
With a bit of custom fab work - sure, why not !!!
They'd be EV-1 wide body injector's, so will fit into a set of CB manifolds or similar... so then you just to plumb up to the TB.
Coil packs piss easy to use in a wasted spark config.
yes! the ECU can even be used. But a suitable ignition module and crank sensor will be needed if you want to utilize the whole system.
those coil packs are tops
What are the part numbers cast into the injectors ??? If you wanna post them up can tell you what size they are...

Nah - they're a Bosch injector. Info I have shows them as being a 200cc high resistance injector.
They're good for about 30-35hp per cylinder, so 130hp or so at the flywheel in a Volksy engine.
60mm TB should be plenty big enough too I reckon.
they are 19lb injectors or as Dave said 200cc/min
30-35hp each? hmmm? so they are already maxed out on my car then? with just a few basic mods?

yeah my old VP is getting close to that I recon.
the final version of the 3800 was actually 153kw as seen in the VY, VT was the last 147kw 3800 also the slowest of them all due to the weight of the
car
This all sound familiar!
We set up my brothers Baja with stock Holden (Camira) EFI parts. It ran but we ended up changing the injectors for bigger ones from a Camry (I think
) as the stock Bosch ones were running above the 80% limit and
it was causing problems.
The GM ignition controllers for a 4 cylinder are not all that common in Oz, but as far as I can tell they were used in almost every 4 cyl GM car in
the US. I did manage to find a new GM ignition module for sale here on the Gold Coast... but that project stalled when I moved house 3 years ago so
it has not yet been used.... one day (soon I hope!). We used the stock Camira dizzy (with the mounting flange machined off the shaft) in my brothers
Baja - the shaft length is exactly the same length as a VW dizzy and the drive 'foot' is even the same. Simple.
We also used the 50mm TB from the Camira but the plan is to upgrade that to the 60mm Commodore TB as soon as possible.
If you do decide to use these parts on your VW it may be worth trying to track down a wiring loom from an 88 Camira too - the loom simply unplugs from
the Camira and needs very little modification to fit an air cooled VW motor.
Let us know how you get on...

you can use the the holden commy delco ECU and flash them with a suitable 4 cyl tune. The 6 cyl ignition control is controlled by the DFI module.
These delco ECU fire the injectors in batch mode so any number if cylinders can be configured with these ECU's The V8 commy use the same ECU as the
V6 but just a different tune and the V8 uses a dizzy while the V6 uses waste spark DFI. That there shows you how versatile these cheap as chips ECUs
are
You can also disable the knock circuit, the BCM enable signal, IAC signals etc... so yeah kind of like a limited GM version of MS
Check out delcohacking.net heaps of stuff on these ECUs and the holden EFI system. People on there have done 4 cyl turbo applications of these
systems if I recall correct.
cheers.
a lot of info here. will have a read.
got told at work maybe the subaru equipment might be the go.
we'll see.
One thing I like about the holden EFI system is its the same type of setup as the type 3 TLE bosch D-Jetronic system except 2 extra obvious
improvements
Direct fire ignition and the oxygen sensor. Apart from that its the same MAP based setup.
Does it matter tht the Holden system is a closed system rather than an open system.
Wont it keep trying for A/F mixture around 14:1?

???? yeah? when cruising. but it adjusts according to the map you load on it and what conditions are present. ie. cruse, partial/full load, engine
speed, temp etc....
all modern factory EFI systems are closed loop from what I know and have seen.
What size is the throttle body
V6 is 60mm V8 is 65mm.
I machined and fitted a 66mm butterfly in my falcodore.
I would recommend that if you buy a modified 70mm TB get it from mace engineering, Jason it think? is the only guy who know what he is doing with
them. The others on the market are typically home jobs where the vacuum ports are bogged or left wide open and air leaks like a sieve past the
butterfly. The walls collapse around the vacuum ports once machined over 64-65mm and need to have a solid plug pressed in and re machined and re
ported in the correct position. Also I have seen one guy sell these TB with perspex butterfly

I don't know if you can see what I have done with my own TB here. The outside was drilled taped and fitted with brass barb fittings, 6mm barbs I
think? the inside was plugged with solid brass tapered plugs then machined down with the rest of the TB bore, then the vacuum ports drilled in stock
position and size, then the outside barb fitting were locked in tight with some loctite.
