Rb25De Into Gts-T Shell

G'day fellow SAU members,

This may have been covered before but rather than paying $6,000 for a non-turbo R33 with high km's I have been thinking about purchasing a RB25DE with low km's and putting it into a r33 GTS-T roller. My question is, would I need a mod plate because the GTS-T was released with the turbo engine and I will be installing the non-turbo engine? I just want to put it to rest so I can go forth and start this project of mine.

And I don't want to hear about how I should just get a non-turbo, I am not stupid. I know what is involved with this installation and I have done plenty of engine transplants with my father over the years. I am just confused on the legality of such an installation.

Cheers

Not sure what the laws are in qld regarding converstions like that.

BUT....if you were in Vic all you would need is to change the engine number over at VicRoads and away you go. Because the R33s came out with that particular engine (the RB25DE) you wont need a mod plate. And i believe this is also the case if you were to do a 26 or even a 20 as they both made appearances in that shell aswell.

If you're doing it so that you can drive the car on your P plates, it will still come up as a turbo model because the VIN number is persistent no matter what engine or engine number you put onto it. Therefore still illegal to drive on your P plates even with the DE engine.

If you're just doing it because it's cheaper or you already have a rolling chassis and are not on your P plates, go nuts. Best people to speak to are your local traffic authority / governing body / RTA.

I thought I would give an update, in Queensland it is legal on p-plate restrictions as long as a change of vehicle particulars form is submitted which indicates to main roads/policing body that the car with that specific VIN is now a non-turbo/naturally aspirated vehicle.

Lol such an unnecessary dick around.

Sell current car

Buy GTS

Spend saved monies on wheels and suspension

Sleep well at night knowing you havnt ruined a completely good GTSt

Profit, get bitches.

Or, you could completely ignore us and do it anyway, your choice,

Í am not doing it, I was going to a while ago then I had a sudden urge to get a skyline again after getting over them because they became quite common in the recent times. Now I settled back on my idea I had about a year ago and that was building a RB26/30. So over the next 18months I will be doing this and a thread will be going up within the next couple of weeks if you older boys want to give me some tips. I have been reading a couple of other threads mostly huddy's and Simonster's, so I have a fairly good scope on oil mods that I didn't know of before. So hate if your gonna hate, but if not welcome :)

Cheers

Smart lad.

Good luck,

Just outta curiosity, how old are you?

I am 19 in July and I am a second year mechanical engineering student at QUT and my mother and father have an r33 series 2 gts-t and dad has been working on that for the last couple of years. So I have some guidance, how do you think I got the rb26/30 idea ;)

TL;DR: we were right?

;)

And that's all it is, urges! Read all the laws that apply to you and THEN consider what you can do with a Skyline :)

Yer, dad was on your side he said why bother when you can build a turbo and in 18 months you can drive it, thank god for parents right :)

2nd year mech engineering wont bag you the experience to build an engine bro.

I've done about half of an automotive engineering course, and I still wouldn't build an entire engine myself. It requires specialty tools and skills that you can't get from anywhere but an engine builder.

I'm not saying don't have a go, but don't expect it to last that many KMs if it's built in a backyard, and I think it's gonna cost ya a bit more than a student budget will stretch to build a reliable 26/30.

save up and let a performance workshop/machinist build it, by all means put it in yourself etc, but I don't think you realise the work involved for a 26/30 build.

good luck champ!

Oh yer, I didn't mean to sound cocky I was just trying to say that this will be my life's work so it isnt just a pipedream and I am going to commit to it. I am going to get my head ported and valvetrain put together possibly with jhh engineering. I may balance and machine my crank with them also. I am going to build the components as I go and in the end get it tuned by an engine builder that specializes in motec ecu systems.

Student wages are shit I know but it won't be going together for another year or so, so I am not expecting to finish it by July.

Thanks for the advice though :)

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      By Duncan · Posted

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
