Hi everyone

Thought I would start a build page for my project

Fj Holden with a RB 25det

post-118613-13772661798743_thumb.jpg

Plan so far is to rebuilt the engine with fairly standard internals, maybe a good set of forged slugs, balancing, a bit of porting new set of bolts to hold it all together, possibly some new cams, i already have a good greddy manifold copy, still need to buy exhaust manifold and gtx 3076 turbo and still not decided what ecu to use.

The front end I have is a new Rodtech unit with adjustable coil overs and a decent set of brakes.

So far it's been fairly straight forward, major problems that I can see at the moment are the clutch master cylinder is fairly close to the inlet plenum and the throttle body flange is a bit too close to the inner guard so will have to cut and re position the flange.

The black spots on the firewall are where the vt brake booster and master cylinder and R33 clutch master cylinder will be mounted.

I will be recessing the firewall approximately 2" so the engine will be sitting back a bit further than in the picture to allow for the radiator and thermo fans

That's it for now

Keep you all posted with my progress

Cheers

Paul

Haven't tacked the mounts into place yet, recently had a new addition to the family so it is sort of on hold at the moment.

I do know that I will need to recess the firewall around 2-3 inches to give clearance for the thermo fan and radiator to be fitted in front of the engine

That is what is controlling where the engine will be mounted

I am not sure what you are going to be doing about your brakes but many fJ folk use the vt common whore pedal assembly

The assembly will hit on the inlet manifold and that's why I asked winter what his dad did and didn't really get the answer we were looking for

Ah I see

I am fitting the rb25det and licensing here wanted the twin system like in the vt so if you loose the front or rear they don't affect the other.

Also you may not have enough volume to accurate the Vt brakes properly.

Licensing here in Wa like to see you use the complete brake set up from a car, mainly because if you don't then you need to brake test it.

I am using the vt pedal box and vr front and vt rear discs and they still want to do a brake test.

Have you spoken to NT licensing and a brake specialist regarding your setup.

Also you will be needing a sump from a GQ pootroll I think it is, they came out with the RB 30 petrol and a RD 28 Diesel engine and have a rear bowl sump which you will have to modify a bit due to the bowl sitting down a fair bit but a shit load easier than making up a new sump.

And

I think that using the hr front end will raise your engine up an extra 120 mm or so.

The front end that I have is a very similar profile to the original FJ front end allowing the engine to sit that 120 mm lower than the hr front end

    • The values for HID colour are also defined ~ see https://www.legislation.gov.au/F2006L02732/latest/text  ~ goto section 3.9 onwards ....
    • So, if the headlights' cutoff behaviour (angles, heights, etc) are not as per 6.2.6.1.1 without automatic levelling, then you have to have to have automatic** levelling. Also, if the headlight does not have the required markings, then neither automatic nor manual adjusters are going to be acceptable. That's because the base headlight itself does not meet the minimum requirement (which is the marking). ** with the option of manual levelling, if the headlight otherwise meets the same requirements as for the automatic case AND can be set to the "base" alignment at the headlight itself. So that's an additional requirement for the manual case. So, provided that the marking is on the headlight and there is a local manual adjustment back to "base" on the headlight, then yes, you could argue that they are code compliant. But if you are missing any single one of these things, then they are not. And unlike certain other standards that I work with, there does not seem to be scope to prepare a "fitness for purpose" report. Well, I guess there actually is. You might engage an automotive engineer to write a report stating that the lights meet the performance requirements of the standard even if they are missing, for example, the markings.  
    • Vertical orientation   6.2.6.1.1. The initial downward inclination of the cut off of the dipped-beam to be set in the unladen vehicle state with one person in the driver's seat shall be specified within an accuracy of 0.1 per cent by the manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to either headlamp or the manufacturer's plate by the symbol shown in Annex 7.   The value of this indicated downward inclination shall be defined in accordance with paragraph 6.2.6.1.2.   6.2.6.1.2. Depending on the mounting height in metres (h) of the lower edge of the apparent surface in the direction of the reference axis of the dipped beam headlamp, measured on the unladen vehicles, the vertical inclination of the cut off of the dipped- beam shall, under all the static conditions of Annex 5, remain between the following limits and the initial aiming shall have the following values:   h < 0.8   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   0.8 < h < 1.0   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   Or, at the discretion of the manufacturer,   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The application for the vehicle type approval shall, in this case, contain information as to which of the two alternatives is to be used.   h > 1.0   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The above limits and the initial aiming values are summarized in the diagram below.   For category N3G (off-road) vehicles where the headlamps exceed a height of 1,200 mm, the limits for the vertical inclination of the cut-off shall be between: -1.5 per cent and -3.5 per cent.   The initial aim shall be set between: -2 per cent and -2.5 per cent.
