Hi guys, i let my cars rego run out about 6 months ago.

I pulled the engine out (rb25det) and am putting in a 26/30. It will look like a stock rb26dett.

Am i going to be able to register it again without trouble?

I can get a roadworthy no worries but am concerned about vic-roads not registering my car because it has a different engine in it.

Am i peaking for nothing?

What issues will i have?

I live in melb if it makes any difference.

Cheers Simon

You should be alright as long as you can provide reciepts for the new engine, they will note the new engine number and may quickly check over the car for major defects. If the new engine is a different sort (RB26 instead of RB25) then there may be some attention paid but I can't see if being too hard.

Then you'd need an engineering certificate. ( i think? )

You need an engineers certificate whenever you fit an engine that was not provided as standard by the OEM in that model, or offered as an option (for that model). In your case you have an ECR33 which had an RB25DET from the factory, and the RB26 was not offered as an option (the BCNR33 or R33 GTR is regarded as a totally different model), let alone an RB26/30.

Of course, as others have suggested, the drones at Vicroads probably won't notice, but that doesn't make your car 'legal' and at the very least your insurance will be invalid (BTW, where do you live so I can avoid the suburb.......)

SteveL........hehehe, sh*t,

so where do i get a engineers certificate from?

Will the mechanics fitting the engine to my car do it?

How much?

Thanks Simon

could make some difference depending on what Vic Roads office you take it to.

I know Carlton has a full workshop and may want to have a close look at the car, on the other hand Greensborough has nothing of the sort and when I rego'd my XT GT falcon complete with tunnel rams the chick asked me if it was a 6 or a v8 o_O

that said you could have insurance probs as pointed out above

haha i cleared the defect on my defectable car at greensborough, they didnt know what they were looking at

i just pointed to the car and said "look, its fixed!" the lady walded over to it and pretended to know what she was looking at, signed the piece of paper and walked back inside to the safety of her desk haha

FYI - The engine number is actually on the block - not the head... So it's not the RB26 they're going to see, it's RB30.

So when you go to vicroads to show them the engine number, they're going to see RB30 + a serial number stamped on the block.

Depending on whether or not the person out @ Vicroads is clued up enough, they're probably going to question the fact the engine serial number that was in there was RB25 and is now RB30.

Good luck though! :P

Cheers,

You really need and engineers certificate. It will only cost $500 as long as your using the original ecu.

Ask Vic roads for a list of there approved enginners.

If your using an aftermarket ecu then you need to do emission testing which is very costly and most engineers won't do it.

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
