So Guys,

I am wanting to know hopefully without a debate through peoples knowledge if it is ok to register a R32 Skyline with a RB25 in it.

Knowing that a R32 Came out with a RB20 and RB26 and you are technically allowed 25% change in engine size which the RB25 fits either side of the RB25 and RB26.

As the RB25 is a great upgrade for a R32 I am trying to figure out if registering it with the RB25 will cause me too many issues like getting it engineered compared to keeping it as a RB20.

Thanks for you input.

did you have to take it through dickson though...... in this case I am only needing a regular inspection, but seeming that the R32 came out with a 2.6L as well all the other engines.

Its such a tricky subject I have spoken to RTA and they said it is fine but you never know with them clowns

You never know, some people have horrible experiences at dickson, some don't I took my 32 over dickson to get rego from nsw to act. They passed it, after I put a rego muffler on. I was defected years later for too loud an exhaust, took it over dickson again, they found that my coilovers were leaking, but didn't say boo about the engine, mind you it's an r32 rb25de thats been turboed.

So it's really luck of the draw I think. You might be okay, or they may decide to pick over every little thing.

In my case mine wont go through dickson as it has a high mount, fmic, exhaust etc so i would get it all done through a regular inspector that wont crack it at the high mount etc.

The only issue i have is the rb25 issue but by the sounds of what i have heard, research etc it is ok.

Where did you see this?

As far as I was aware, any modification from factory requires certification.

Some people on this forum have convinced the person doing the inspection that RB25det does not require certification in a R32 because, as Chris mentioned, it an RB25 was a factory option at the very end without being specific.

I'm pretty sure the RTA that being referred to is Rego ACT/TAMS(???). There isn't a Australia wide department, unless you were thinking about The Department of Infrastructure and Transport. They provide a set of standards and guildlines for states and territories, it isn't supposed to be the hard line at the moment.

I thought it was %15

And that was 20 years ago, if they changed it, it would be even less or nothing by now.

lewis in SA make a 2.25l which is %12.5 bigger, still under the %15.

I had a 1600 celica with a 2l but it still said 1600 on the block. how?, 1800 crank and rods with a 3.5mm overbore, and a Yamaha twincam head.

Careful, as the 32 with a 25 was non turbo, and the 26 was a GTR with different brakes etc.

You may have to be real sneaky, but if you get it on paper... sweet.

      Who has a Infiniti Q60, Q50 (V37)?

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
