R32 Engine Swap

[Adz2332]

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

Thanks guys....

Taking it to the pits would be a pain as it has coilovers to...

Already runs a rb25 box tho... could have a look in my shed and see if i have the bigger brakes to...

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

bumping an old thread of mine.....

whats the best way to find out if any other mods are needed for the swap apart from r33 brakes that i have already got?

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).

Whats the chances of getting a rb30 with a 25 head legally into a 32 passed?
