I have an R31 with a vl rb30 instead of the Nissan
I'm wondering what turbo I should get? I would be going for garret but iv been told to get either the T3 or the T03..
I'm not sure on which one to get and what the actual difference is.. any advice would be appreciated
Not looking for heaps of power want to do the car up, drive it on the weekends and when I feel like having a bit of fun.
Any advice would be appreciated as well if you send could some links of any turbos or even photos of your set ups that would be good cheers

The "stages" are from Gran Turismo. So you'll have to refer to Gran Turismo 7 (when it comes out) to find out the specs
When I looked in crow cams a while back for r31 rb30 it had 3 stage cams so idk

Lol, stage 2 cam. Good one.
Also who the f**k is telling you what to get? It's all kinds of weird.
Crow cams? Why’s it funny?
this guy I spoke to on Facebook that has an r31 with rb25 gearbox his been telling me what he did
-
Someone also told me to get r33 clutch, flywheel, sandwich plate, bearing, fork and he said mount.. guessing he means gearbox mount I’m not exactly sure
but yeah any advice would be appreciated..
worst case I don’t end up going turbo at least iv got a good gearbox, an then I can eventually put a stage 2 cam or something

Yeah there's no point in choosing things on that list like an old stock ECU, the VL injectors, etc etc, just because they are second hand and therefore "cheaper" than a new alternative. You'd be insane to do anything with a VL ECU and injectors, some 35 years since they were not even at the apex of automotive tech.
Decent aftermarket ECU, injectors, fuel pump - that's the base of engine management. It will cost more outright, but A) you will be able to find them, because good luck actually finding the 2nd hand parts anyway, and B) they will work about 10000x better and cost you less in the long run from not having to clean the injectors before you start, replace something 6 months down the track because it let the smoke out, etc etc.
Greg's estimate of 20-25 is probably low. If you're paying anyone to do much in the way of labour, like working out how to mount the gearbox, scrounge around among wrecker contacts for bits and pieces, etc etc, then the $$ can rack up much faster than the parts themselves.
I wouldn’t get secondhand injectors I found a guy but his charging 900 so prob won’t even bother since I can get these for cheaper and they seem better, with the ecu probably better if getting NISTUNE
I’ll send some photos of the injectors anyway like I said I’m just trying to find out the cost and what not I’m more leaning towards getting an rb25det gearbox since mine will eventually shit on me it’s already playing up abit, just would like more info about the doing the conversion from what I know the tail shaft has to be modded, I need an s3 auto cross member gearbox mount

Nice job man! Really sounds like a plan. Ive just turboed my r31 silo and plan to chuck a rb25 box just like your doin, decent strong box for 200kw 😁. Next step for me is getting it road legal, need engineers cert here in vic, lucky in qld you can just grab a mod plate. keen to see more pics or an update on progress of the 31 on its way back to street legal!
Hey man I’m from Melbourne as well, what turbo did you end up getting? And how much did it cost you to get it all done? Because I’m wanting to do the same with mine
as well have you got the stock transmission or? How’s the car holding up cheers

An update to the build, it has been a while since my last post.
Progress on the car has been limited to my mate doing stuff to the car in his spare time. I have about 5 weeks in the year to work on the car myself.
I have spent the past week or so working on the car, it has gone backwards in a sense.
since my last post I have mostly found stuff I need for the stock conversion.
- The car now sits on R31 LCA's with N12 Pulsar Tie rods, held onto the knuckle with Gktech Adjustable tie rod ends.
- I have since ordered Gktech tension rods as the ones in the car had crusty and worn out rose joints
- I have sourced some R31 Ti stock wheels and sold the D shapes as they weren't legal.
- instead of buying a GT3076, I ordered an anti surge housing for my GT35, ended up being far more economical.
- instead of using the recaro, I purchased a pair of R32 GTR seats, They look far nicer in my opinion.
- I replaced the cut and shut s13 knuckles for uncut ones.
- Mishimoto catch can has been purchased
- Sub and amp has been purchasedSome things did not go to plan, I purchased a VLT ECU and a stock RB25 turbo, in the process of trying to clock the near 30 year old turbo I broke the exhaust turbine, this ended up being beneficial because now the car will make no boost for the mod plate. Now the car uses a stock R31 ECU and NA injectors. The high mount manifold is retained with a Nissan 6 bolt to V Band adapter for the dump pipe.
Me and the mate who is working on the car went halves in a TIG welder, so he is doing the exhaust up for me, we discovered that the exhaust was held on with one hangar at the rear and nothing past the diff (held on by the turbo V Band), we have since addressed this as well as adding in another muffler and an exhaust tip, as somewhere down the track the old blast pipes were sawed off the car.
This is my first time properly building a car, the frustrating part was getting half way through an install and then needing a certain part which could only be purchased online, so the car sat in limbo until such part arrived.
Lots of other little things that don't really need to be mentioned have been fixed, this car was built with ebay parts 10 years ago, and the past decade of neglect from it being thrashed hasn't helped.
The car doesn't need too much left to be ready for the roadworthy, it only needs the following:
- Handbrake installed
- Injector seal kit installed onto the n/a injectors
- speedo drive installed into the 20det box
- catch can installed
- loom and ECU installed
- tension rods installed
The local mod plater in launceston is unhelpful to put it nicely, I like being charged $300 for the car to be looked over and told I need "ADR Coilovers" (Which don't exist by the way) all whilst being spoken to like I'm a bogan with a rats tail and ugg boots. So suggestions on where to get it mod plated in Tasmania would be super useful, I would travel statewide.
The current plan for the car once it's mod plated include:
- 5 stud conversion front and rear
- EL rear brake conversion
- Panhard rod correction kit
- Adjustable rear trailing arms
- Front strut brace
- rear adjustable trailing arms
- new dump made up so the 3582 can go back on
- head unit + stereo
- trim pieces fixed
- SR20 Throttle body conversion (TPS works with the Haltech)
- paint the boot in some sorts of bed liner as the boot trim is long gone
- 33 Front brakes with GTR rotors
- 33 booster
- 25DET box (the 20 box is really nice but I want to get a 25 box whilst you can still buy them brand new from Nissan)
- S13 Rack conversion - new injectors and fuel rail
- possibly external oil cooler
- bigger sway bars and new bushings to suit
- Venations!!
Probably more I forgot but that's off the top of my head.Here are some pics. Apologies I don't post super often. I try to keep the fourms alive!!
Hey mate I seen that you said you can buy the rb25det gearbox from Nissan, do you have a part number because I just off the phone with them no go..
-
If anyone can fill in the gaps of what else I would need Or correct me if I’m wrong so I can turbo my car, that way I can actually try find out how much it would actually cost me and then I can make a decision from there would be greatly appreciated
so far I know
VL turbo injectors
VL turbo ECU
Dump pipe
Intercooler
Garret T03
Piping
5 Stud conversion for r33 brakes
Engine rebuild
RB25 gearbox...
RB25 driveshaft..?
Like i said if I’m wrong about anything please correct me if there is anything I missed please let me know..itll just help me make my mind on what I’m going to do.. I’ll basically find how much everyone part will cost me and if I’m not happy I’ll just go with an NA build
Thanks

The thing is, all the cars you see that work well, are money pits. Same as the ones that don't go well.
I could say random comments like "If I sold mine for 70k, I'd have lost money on it" and this is when it was a 10k buy for the base car, back in the day.The reason its bad is because it is a 30 year old used engine that was not designed for boost. It's infront of a 30 year used gearbox that was not designed for boost.
All in a car that has everything else, not designed for boost. Not really anyway, at the levels that people on the internet hold as an entry point for cool factor. Do you think the driveshafts, bushings, bearings, subframes are also not 30 year old items, not designed for boost?
Do you have a $100,000 budget for this? Answer honestly. Because if you don't, and this is your first foray into cars and modifying, you will need that much, if you truly want it to do everything 'well' and look the part.
If sentences like that make you think "oh jesus f**k no, agggh that is more than I bargained for" then what you really should do is
a) Enjoy the car for what it is, an old cool retro ride that isn't really fast but isn't pretending to be
b) Sell this to a collector or passion project guy who will do the above
c) Take your $40,000 budget and consult a Subaru/BRZ dealer and buy the new GR86.
It will kick the shit out of this project for livability, reliability, sanity, and will absolutely be a great platform to learn to wrench on cars going forward. You will love it equally as much as your R31.
The truth is I cannot imagine any stock Skyline build in February 2022 that comes out cheaper than a brand new GR86 from a dealership, with a warranty!Any modified skyline project that you buy that has already been modified well also costs more than aforementioned new GR86/BRZ, with a warranty!
Sorry, don't have a $40,000 budget at all? There's plenty of hot hatches out there that do a damn good job nowadays and for any road use make a damn lot more sense tbh, which is why you see so damn many of them.
I am not having a go at a young guy who is excited by the world of car mods. We are all those at some point. This is sincere advice.I don’t have that type of money to drop, even just thinking about what @mlr said 20-30k even thats abit of a stretch for me I will have to have have a good think about what I’m doing, especially before putting a turbo in because like as everyone has said will need the rb25 gearbox and drive train and the rebuild on the motor will be very hefty so I will be thinking more into so I do appreciate the advice
I’m going to be spending 700 tomorrow to get an alarm on the car with central locking because it is an old car which I do like an i do intend on keeping it, so maybe I’ll just stick to the smaller things an go from there and make a decision if I really want to go that far and throwing in a turbo

Possibly the 1st time you lay into it, possibly the 50th time
Anyone can make big power bolting a turbo on a car, making it reliable is the hard, and expensive part
If you don't have $20-30k to drop on the engine and drivetrain then just do a nice NA build
If you want a fast car, buy one that someone has already spent the money on making it fast and reliable
I’ll have to think about what I’m gonna do weigh out the pros and cons and what not and the money that it will cost
I appreciate the advice though

RB25DET box would be the obvious choice. But a brand new one is in the area of $4000 now and good 2nd hands ones are not changing hands.
Otherwise T56 or Tremec conversion. More money. More money.
A lot of money, seems like iv got a money pit on my hands lol..
So even real low boost it’ll still eat through my gearbox you reckon?
How long Roughly do you reckon it would last my gearbox with the turbo ? -

Yes mate, Headspec in Clayton.
How much roughly you reckon I’ll be spending ? Does he rebuild the motors as well?
got a quote in footscray for 7500 for a full rebuild and to upgrade some parts so I can run it turbo instead of na -

And if you turbo an RB30 in front of an old RB30 NA manual gearbox.....the gearbox will not last long. Even at lowish boost. Too much torque for the poor little thing.
Iv heard same thing, heard it will eat through my gearbox... what gearbox would you reccomend ? And how much would I roughly be paying ?

This, or 3rotor.
3 rotor ? Sorry I’m not familiar with 3 rotor

Oh, and BTW, don't turbo it, leave it stock, repair anything you can and sell in in 10 years for a fortune. You have a collector's car.
Will going turbo really affect the value ?

Or Barra
Hahah my older brother said the same thing,
im not to familiar though
are you meaning Barra motor or xr6 turbo?

Yes you can
Yes you should
Keep the single cam for "historical" reasons (twin cam heads go foe drug money)
There is a bazillion things for sale on the interwebs to help you do it
Talk to the person who is building the engine for what you need
Finding a transmission that will survive could be a costly hit to your budget (anything RB is going for drug money)
Thread needs pics
Yeah I agree finding a rb25 transmission will be very difficult
what is a fair price for a rb25 transmission?

What difference do you think the block makes?
There is clearly a plug in there you pull out for the oil return. So that's handy . Oil feed is super easy to sort out as per above post.
Are you going to turbo a 30yr old wrecker engine? Sounds fun.
What do you mean by that?
what’s wrong with going turbo ? -
I’ll try get some more photos up tomorrow
what did use want me to take photos of ?
-
Someone was saying to leave it stock because it’ll be a collectors..
would a turbo really affect the price in a negative way?
I wouldn’t of thought so in my opinion -
@Shoota_77 is your machinist located in Melbourne?
-
in genreal any bit of advice i would appreciate im new to cars..
for thr 1st question does anyone know if its an A8 ?
i know im a noob lol sorry to bust balls just a lot to take in
cheers
-
yeah well i plan on thrashing it a bit first then getting it rebuilt then chucking in a turbo.. but i want to make sure i have the right motor for it
Im obviously new to cars im asking for questions i know im a noob no need to bust my balls some advice would be greatly appreciated.. so if this motor is fine for me to turbo like you have said since it has a plug.. then sweet unless use have some advice for me that would be apprecaited as well man.. i just want some advice im new to cars
-
I basically want to know what block i have..
What turbo to get for my rb30?
in RB Series - R31, R32, R33, R34 (1986-2002)
Posted
That's why I'm asking questions so I can get an answer....
Like I said it's not meant to be a drag car
Even abit more power then the factory vl turbo or the same..
So what's your opinion on which turbo to get then @Ben C34
