E.F.I. Wiring Kits for HD-HR Holden fitted with Series 1, Series 2 or Ecotech Holden 3.8 Litre V6 or V8 EFI Engine and Transmission.

Fitting Details; We recommend that this conversion, whether it be a V6 or V8 engine that is to be fitted, should be done with the Castlemaine Rod Shop under body bracing kit, which bolts under the car and incorporates the gearbox crossmember to which the handbrake mechanism is attached and a tailshaft safety loop for safety sake.

Only a very minor welding job is required where the rail locks into the rear spring hangers, the rest is all bolt in with only holes to be drilled by the fitter.   The frame then allows the vehicle to be easily jacked up, lifted on a hoist and of course prevents body deterioration (fatigue).   A raised floor tunnel is supplied and can be screwed, welded or pop riveted in.

The crossmember centre section is cut out for sump clearance and strengthened considerably.   A strengthening plate is added to the bottom to make the underneath look smooth. A rack and pinion steering unit is fitted to the front of the crossmember.

The existing suspension components should be reconditioned with new bushings and ball joints as necessary then re-fitted to the crossmember. A disc brake conversion kit (DB 8) is available from the Castlemaine Rod Shop to fit HQ-WB ventilated discs to the drum brake spindles and is essential.

The rack and pinion kit consists of approximately 34 pieces including reshaped steering arms, wishbone strengthening rods, stabiliser brackets and bar connectors, all mounting rubbers, a length of 9/16" steering bar, bushes, bolts etc. No universals are supplied as these are standard Torana units. The steering column used is up to the fitter, however CRS can supply a modified EJ-HR unit along with a specially made extension to clear the exhausts. If in Queensland, this column is part of the requirements and a specially made floor mounting bracket must be used. This is not essential in any other state of Australia (or N.Z.), where you can fit whichever column you wish. An LH Torana unit is a good one to look for.

Extractors are required for V6 & V8 conversions, with provision for  screw in oxygen sensor. It is also recommended that they be JET-HOT Coated, which we can also supply. This process stops heat dissipating through the pipes, stops corrosion and looks great as well as giving your extractors a life time guarantee.

If using a post 1994 engine please note that the matching transmission has no provision for a mechanical speedo cable. We recommend that you use a pre 1994 transmission if you wish to retain the original speedo. If using the post 1994 transmission a matching digital speedo is required and will need to be custom adapted into the dash.

We have found it best to set up the battery on the right hand side and the air box fitted to the left hand side. The E.C.M. is mounted back in the original position (LHS kick panel) or above the glove box. Our wiring loom is supplied on a changeover basis for the engine to computer loom. If no changeover is supplied an additional cost of $200 will apply.  Prices may vary if Ecotech engine is used.
