I'm doing up an EK Holden I ve a couple of blue and black sixes to choose from to get rebuilt for it.
I'm collecting a fuel system for it slowly VK efi manifolds will be going on it now the question Is there any point In using the vk ecu or would It be worth while to convert a delco system from a vn .
Is anyone able to give me a run down of is it worth it and a basic how they went about it and what sensors Ill have to get .
And the how the memcail is reprogramed ?
or should I be looking at a motec or a wolf ??
I have most of both systems .
option 1 use the vk efi system?
option 2 convert it to a delco ?
while Im asking annoying questions
Im thinking about using this crow cam
(35666) HOLDEN 6 CYl. 1964-87 Mild Hyd. Cam
Part Number 35666 Lobe Separation 112 Valve Lift
Inlet Opens 25 B.T.D.C. Inlet Closes 65 A.B.D.C. 0.420
Exhaust Opens 74 B.B.D.C. Exhaust Closes 26 A.T.D.C. 0.443
Inlet Duration 204 at 0.050 270 Advertised
Exhaust Duration 214 at 0.050 280 Advertised
with a 3:08 diff ? good or bad idea? trimatic
I wouldn't bother with the VK system, unless you plan on leaving the engine completely standard
apparently the Delco conversion is fairly common & popular these days. If anyone knows, it will be the people at delcohacking.net • Index page
There was a guy onn here called sammy he done a few of these efi setups i believe he had an ek of eh with a delco powered 202 its not hard to do if your cluey with wiring and got a decent mechanical knowledge

I also recommend converting to a delco system, from memory the setup as used by VN-VR v6's runs of 12 pulses per crank revolution, i no zip about tuning so im not sure what the minimum amount of pulses you can have or be programed into it are but you could use a VK EST flywheel and CAS and have additional crank angle pickups machined into the flywheel as EST only uses 3.
Some people use the pulse from the dizzy, you might even be able to fit the VN CAS and pulse wheel to the front of the engine with a special made balancer from Precision parts.
im not sure, but will the RB30 EFI system work?? just for the fact that both engines have a dizzy ? i could be wrong...
Use a JE camira efi setup less ####ing around than vn style

The Holden EFI 5L runs a distributor too, so not a problem
Delco is the way to go. One of the most versatile factory ECU. On the Kalmaker site, they've got a Harley Davidson & a V12 Jag running on the Delco ECU
well there you go, but i did say that i wasnt sure... lol i just thought that both being I6 engines, with dizzys n the fact that so many VLTs around just woulda thought it was fairly tunable...
use the VK injection manifold, fuel rail, injectors and chuck the rest and fit either a haltec E6x or Delco setup, I had a haltec on my VK with good results

Loads of VB-VK information, All you need to know about EFI 5L Conversions Ultimate EFI 5L Conversion resource "
Wanted B Cast Heads PM for details
the JE camira system is the easiest to use.
V8 holden uses a hall effect sensor in dissy for pick up 202's dont have this.
V6 holden uses a crank angle sensor for pick up 202's dont have (sure est is possible but theyre shit anyway)
VL uses a crank angle sensor in the dissy for pick up
JE camira uses a VR box on the side of dissy for pick up. HEI 202's dissy's have the same box (EFI uses same box)
Making JE camira best system to use
Only hard part if i remember is locking your dissy which requires the removal of mechanical advance other than its a bit of wiring mods ( changing adding plugs extending some wires) And getting a tune done.
Use vk EFI manifold mod a v6 throttle bady to fit (you get to use better idle setup) Change injectors to a more modern type for better economy, add a map sensor and a couple of new sensors (coolant and those sort) leave off oxy sensor if you want and rewire fuel pump to suit the delco

cheers for the links.
I like your thoughts on the JE camira system Pub247 any info on its wiring diagrams and how to tune it is now what Im trying to find.
Off to the pick a part .
look in delco ecu conversions on delcohacking.net few threads on how to do 202 to delco ecu its easy as theres even a couple of tunes on there to suit 202
I tune the oldschool way fear on the passengers face and knuckle colour cant go wrong
tabbacco is still my favorite vegetable
