Hey all

a mate has a r32 gtst and the old rb20 has given up the ghost.

its a registered turbo rb20.

I have a spare rb25 in the shed.

my question is, how do you go legally registering a 25 in a 32?

To get it on the papers would u have to go through regency?

Or is it an acceptable engine swap?

Cheers

Variety of answers. For mine it was regency and make sure have adequate brakes on the front that suit the weight addition - i.e. R33 front calipers etc., or 4-pot type-M R32 gtst brakes. That was from my experience. Though, you wouldn't want to keep the RB20 gearbox with an RB25DET under the hood...went through 2 gearboxes with the RB20, so chucked the 25-box in with the RB25.

I looked into this when I had my 32. The best advice I got was to buy a front cut from an R34. Chuck in the brakes, motor, gearbox and wiring and go from there. Costs a bit but those motors are brilliant and if you put that motor in on the original gearbox you will blow them as mentioned

Coil overs are fine as long as the ride height is legal. That mod is fairly easy to make legal as long as the brakes are done. Making the wiring work is a different story however haha

Are you sure about that?

It's my understanding in sa they have to be engineered and have a mechanical way of limiting how low they can be set.

It'll be different in every state. Australia is fun like that. But yes it has to be engineered but apparently there isn't much of a drama in doing so at a legal height. This is according to an engineer I spoke to around 2 years ago. Things may have changed since then and be different in different states

Basically submit the form, you'll get a list of requirements needed.

Fulfil those requirements, do the tests, pay money and get a form saying its all legal...

Wont necessarily mean you wont get defected for it, just means you can roll through regency without issue (whilst paying them to inspect you're paperwork saying it's legal).

      r34's love to squeal

      By Nizzy_R34 · Posted

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
