Id like to hear from all you guys that have dropped in an rb25 into the r32

just wanna know what happends with the vin number and all that stuff at vicroads

do you need engineers to change it?

my engine blew and i wanna drop in the 25 but im worried about the legal BS

insurance i suppose will also be an issue?

cheers

not sure if it is the same in vic but i know for QLD if you change your engine to something that was not designed from factory to be in there then you have to get and engineer to approve it, as far as rego goes the VIN is the same you just take the engineer cert to the dept of transport along with the new egine number, in QLD you also get a mod plate put on the car

the r32 came out with an rb25de from factory. so dropping an rb25 into an r32 shouldnt have any problems with rego.

as far as i know, in NSW - if the car came out with an rb26 as the biggest engine and you drop in another of the same series engine that is 2.6L or smaller than you dont need engineering for it.

which means if you dropped in an rb30 you would need engineering.

best thing to do would be to ring up your local rta and ask.

You need an engineers cert.

The motor is over a 100cc upgrade.

What you do is, contact the engineer first before the conversion.

Have a chat to them, tell them your intentions, and they will tell you what is required and what they will need to see done.

Things like brake upgrades, gearbox upgrades, that sort of thing and whatever else they deem neccesary.

There is a list of Engineers on the VicRoads website :)

The people that have not bothered, generally have been bitten on the ass.

Once you get a cop that has half an idea, you are put off the roads instantly until you fix it.

Which costs you $$$ as you gotta tow the car everywhere.

If you ask me, do it right the first time and it wont haunt you later on.

Especially because the engineer is probably going to ask for brake upgrade etc etc.

Which is more for your own safety than anything else even if you think the car doesnt need it

still like to hear from someone who's done the upgrade

if they even bothered getting the engineers?

I put a Stagea RB25DET into a R32 GTS4. All I did was tell VicRoads that I had changed the engine. They checked that the engine# on the block matched the Engine# on the piece of paper - "Robert is your father's brother".

i just spoke to an engineer he said to do it properly you need to change the whole drive line to the r33's

then get it registered all standard then what you do to it after that is up to you bigger tubro ect ect ect.

i think im just gonna re build my 20 and strengthen all the internals and keep all my mods

if i get epa'ed at least ive got all the standard parts to change back

otherwise i might as well just buy an r33

did he say anything about the brakes? ive got a s2 box with the 25 so im assuming thats ok? I thought you only really had to change the breaks if you put a turbo engine into a non turbo car - 4stud brakes and shit ?

yeah thats right..

he didn't say anything about brakes but basically the whole drive line diff box ect ect

im not too sure about exact things but it sounded like way too much stuf

the thing is its ok if you got a stock looking engine bay

with me i have a top mount manifold to a big ass turbo its no where near stock

a cop will take one look and send me to epa. its not that hard to change bolt on parts back to standard but epa will see its a bigger engine i would have to change the whole thing back

does anyone know how to get more low down torque/power out of the rb20?

by doing engine work that cant be seen like Flowing the heads? would that give more power

im already gonna put forgies conrods and stuff but i want more low down power

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!

      Stock rb25det neo questions

      By GTSBoy · Posted

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Rb25det Belts Change

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
