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

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.

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
