93 R32 Gts-t With Rb26dett

[luvboost]

hi guys i dont no if theres been a post about this before i just couldnt find it. im just wondering if that i get my rb20det ripped out and get a 32 or 33 gtr rb26 droped in will it still be road legal if not could i get it registered

thanks

[Dani Boi]

It wont be road legal, have to go through pits to get it approved.

[luvboost]

okay but if i go through pits will it pass?

[Dani Boi]

Possibly. Have a read of this

hey man

i have an r32 gts-t that had an rb20 in it and ended up putting an rb25 in...

Got the engineering certs done also. It took about 4 months for everything to get done, more the fact it was just waiting for the forms as there’s a bit off sending and receiving from the tech section to you, from you to the engineer and so on.

when you do the conversion make sure to keep the rb26 as stock as possible, example stock exhaust.. that way there is less testing done.

good luck with it man

I was told if the exhaust and cats are stock you dont need an emmisions test?

Can be done, Bubbas gone from a 20 to 30 and I went from 26 to 30

I think it just depends which inspector you get @ the pits

thanks for all the help guys i called hyperdrive and he said why do i want the 26 so i was like if im gonna do it i might as well go the big bad boy he said 26 are double the price of 25 for only another 100cc. so i think my minds on a 34 neo rb25 cause he said that was the way to go but do you thinnk im gonna get a big gain from the 20 to 25 or should i stay doin the 26?

The thing about 26's isn't just the displacement, they are a much better engine. I believe they have bigger bores than the other RB engines? Which allows them to achieve such a high redline. And they can also take a hell of a lot more power on stock internals. An RB25DET Neo starts to get risky and unreliable at ~350rwhp, where as an RB26DETT makes 320hp from factory... If you want huge power, go the 26. You will save a lot of money spending more on the 26 now, rather than spending more later trying to repair the other engines when they blow.

[gazza750]

simple answer is yes it will be legal if it is signed off by an engineer and approved by pits examiners

[R32 Driver]

25/26/30 all have the same bore 86mm i believe

Difference is in the head, Id go with the 25 NEO as they are much cheaper then 26s to replace (alot less work too without the awd sump and all)

25 NEOs can run 400hp safely if tuned right, only think good about the 26 is the forward facing plenum...

Or do a 30 conversion if you want the "big bad boy"

[luvboost]

thanks for the help

if u say rb30 how would i go about doing it, like getting the motor from a r31 then adding the turbo parts? or can you get them turboed already?

i got told at the pits when i went that you cannot put a 6cyl motor in a car thats ment to have a 4cyl and you can not exceed a 0.3L capacity difference.. your going up by 0.6L i gotta 25 in my 32 thankfully mines been engineered so he couldnt do anything , who knows they may not care...i got a mate who had a 32 with a 26 he got stickered went over pits and they made him get a engineers certificate... good luck with it man

You got fed bullshit.

You can pretty much put anything in anything if you have the money to get it engineered/certified/emissions tested.

The ADR's say you can increase capacity by 20% with the same engine configuration without needing engineering.

But, as has been said, it can be very subjective.

I took my 32 over the pits with an RB30DET that looked pretty stock under the bonnet except for pod filter, fmic and full exhaust. Passed so easily it wasn't funny, all they did was notarise the new engine number and take it for a drive (and then thank me profusely for the drive.. he loved skylines hehe).

^^haha nice, one of the guys who took mine for a drive started shaking and said "just dont kill yourself in this thing" .. and that was after i turned the boost down from 18psi to 10psi!

as far as rb26 into ur r32, just do it n worry about it later

[luvboost]

bubba im thinking to go the same way as you with the rb30det but im lost on how to go about getting the motor and turboing it. do importing shops sell rb30s or would i get one from quokka or somewhere like that. and wat turbo parts did you use like rb25? i dont no very much about this sort of stuff.

and i read that other link about the r33 rb30 but was still lost

Yea like i said some just dont care where as some are hard arses i was shocked when he said you can only go up by 0.3L and he was gonna wreck me for a 25.... untill he saw rego papers , the guy i got was so messed he said on my re-inspection form that my fire extinguisher had to be re-postioned away from the foot area on my passegner side (i dono if its "illegal" to have it there just very weird)

[Morgz32]

best to buy a 30 from the quokka... cheap as chips roughly 150 for a block as far as turboing it goes from my understanding all blocks can be turboed cause they all have galleries for the turbo's oil and water lines just smash a 25 head on... 25DET heads require welding and tapping for oil to the lifters.. i got some info ive scabbed up if you need i can send em to ya

Converting to the RB25DET is much more viable if you are on a budget, as it's close to pull out and drop in, once it's done you will have little trouble with issues changing a motor, I've been pulled over multiply times and police have never noticed the motor difference between the 20 and 25. In the case since it's a newer motor a few bit's of paper work need to be done, this is based on my experience a few years ago with a yellow sticker RB20 R32 running a RB25 without papers and having to update the vehicle. If you want to complete the 26 conversion I'd budget near the $10k mark once you changed your gearbox, clutch and all minor bits and pieces. RB30 idea running a 25 head is viable, again once all the hands and exchanges have taken places with parts and servicing your $50 block will be near $5000 once you can drive out, assuming you are going to a run a stock turbo, beyond that the figures jump up. I'd suggest getting advice from people who have completed conversions and what sort of price they have payed, also figure out what sort of power and delivery you want. More to the point, my friend completed the RB26 swap for his R32 about 4 months ago without any issues, after all costs the figure was close to what I mentioned earlier, with cheap parts and good value labour from a local workshop and is still registered without any issues and has been pulled over several times by local police. Simply avoid the big single blowers and you will be fine

You can build a 30 and install it on a budget and come out with change in your pocket from 2k BUT, you really need to have a good idea of what you're doing and access to hoists and tools etc.

That's what I did for my first 30 (slightly different as I got a matching block, forged pistons and 25DE head but you could do a stock piston rebuild to keep it cheap) and it was a weekend conversion.. took it to my mates shop Friday afternoon, drove home with a 30DET about 3am Monday morning
