#RB30 #RB30e+t #RB30et
To clarify a few points, the A6 blocks denoted the 9.0:1 CR (NA), while the A8 blocks denoted the 7.8:1 CR (Turbo). Later 'Series 2' A6 Blocks had drilled and tapped provision for oil and water feed and oil return for the turbo.
Alright you convinced me, I'm swapping out my 25det for a rb30e in my r33.
Interesting, good luck man
Ive done that in mine bro fkn wicked as
Mix both rb30 bottom 25 top
Sounds weird form a viewer perspective but I’m glad your getting some ads
Making 594whp on stock pistons and rods here. Just arp rod bolts and head studs. Running up to 7500rpm
4:30 repping that Scotty Kilmer crouch
Only vl commodores made before March 1987 with the a6 engine are “series 1”, vls produced after then all have “series 2” engines
Also the series 1 and 2 r31 boxes have a different 5th gear to the vl box, the r33 na manual doesn’t have the revised synchros like the rb20det box, also the tailshafts are the same length between the small boxes and the big boxes like the 25det and 30et boxes, they just use a different yoke, good video though 👍🏻
Thanks for the info mate! Never really got to play with VLs before they got too expensive so only knew what I've read and heard.
As someone who’s just got back into an R31 this answers a shitload of questions! Great vid, thanks mate
Thanks mate looking at getting an rb30 patrol
This is extremely helpful for me right now. Just picked up a project R31 wagon. Factory vl manifold with a rb25 turbo bolted to it, massive front mount intercooler and an oldschool nistune chip but its lacking an exhaust and a tune as far as I can tell and a few other loose ends tied up. Just need to find someone near the Nth east cost of NSW/south qld to tune it
Great video mate, theres some great info in there, I’m sure some of it will come in handy if I ever turbo my RB30 GQ
Great info mate, really enjoy all your R31 vids.
I'll keep all of that in mind for when I can afford to import a R31. 🤣 Smesh loike for good luck!
this is awesome been waiting for a video just like this! always good content from you blokes!
The carby engine in the gq’s have a slightly different cam for more low down power
RB20ET content will be appreciated if you can. Especially cross compatibility with any rb30 hardware
The vl commodore came out in a series 1 and 2. The series 2 vls had the provisions for oil feed and water feed etc.
Correct
Is the 87 model vl commodore come out with a series 2?
@@spiromikropoulos8014 depends what month it is.
Love this rb30 gear, great vid bud
YEWWW. Such an underrated channel!
Very informative content, Professor!
Love this video, thanks. My son and I are about to pick up a stock R31 and start the project. Don't suppose you have one of those RB25 5 speeds you want to sell? 😁
Link ecu goes straight into factory ecu housing much better ecu and come with base tunes also you might want to look at the new 30/76 Garret turbos much higher hp rating than the old oringinal 30/76 my vl was the gtx 30/76 rated for 550hp at the crank my rb30 vl was making 465hp at 6500rpm on 22psi plenty of turbo left with lpg r33 manual box now has the latest gtx30/76 series 2 rated at 750hp
Anthony Whelan do you mean the new G series garrets with the 9 blade turbine wheels?
Yeh the link plug ins are great! We ran one in the silver R31 build on the channel about 2 years ago 👌
Leprechaun Laboratory no it’s the gtx30/76r series 2 but it also has a 9 blade compressor wheel much more efficient than my old 11blade wheel and slightly different front compressor housing not a lot of difference to the new g series but now I should be seeing same power at lower boost of same boost roughly 50-65hp more and lower egt
Wasting your time with tiny turbos. Get a gen 2 35/82r. 25lb @ 2700rpm with camtech 272. Not much lag at all.
Love this nerdy stuff!!
Great video learnt a lot.
Very informative loved it! cheers man!
Series 2 VL's with the A6 motor have the oil and water tapped into the block. Have an 88 Berlina at home. Message me if you want photo proof
I have 87 November build same motor as you
Mines an A6 and has the oils and water threads tapped already, series 2 boss
Great video
What about LS1 swap. What Brakes do i need if i need to drive on the road. Ofcouse engineer cert.
Hey mate how easy is the conversion from the ZD 30 motor to an RB 30 and I GU patrol wagon with an auto transmission
How much is a nistune board to put in a stock n/a ecm
Awesome video, lot of great info. in there that's hard to find in 1 place.
Hey have you still got the rb30?
Howsit bro looking at building a rb30et was wondering if the rb30et has the same oiling issues as the twincams what would u recomend leaving stock pump or upgrading want to biuld for around 250 300kw
Hey man what do you know about the classic lifter tick on the RB30. I’m looking at a car with a slight lifter tick and potentially worried it’s worse than I think and could be pricey having to fix it
Let me know your thoughts on all of it
Cheers man
Hey mate just wondering what throttle body is it running bc I have a rb30 with a high mount on it and I want to run the Excelerator cable the other way so it is away from the turbo so Is doesn’t melt again
Cheers
Haha olde mate from tik tok how random
Hi mate ✌️ I have a 3076 sized turbo, I’m wondering if it can be ran on a VL turbo ecu or whether I’ll have to purchase something properly tuneable like a nistune etc
Cheers dude, hope all is well!
Hey mate is stage 2 crow cams sny good and whats Rb30 NA cams specs advertised duration etc..
Hey mate, just wondering if you could give me some quick advice on a turbo choice For my vlt. Power goal is 400-450 and it’s auto. Is that possible on a .82 ar or would I have to go 1.06? Would like it to be as responsive as possible
I’m running a 272 camtech cam pushing 118rwkw
what's sort of replacement coils would you recommend for the std distributor setup?
Does anyone know if you can use a Holley sniper as an ecu if I’m wanting to add boost to my gq
Whats the cost differnent in set ?
how much did rex spend on his rb30 he just built
How realistic to put a SV6 motor in these ?
If this turbo convertion cost around 3k im just thinking why not rb25det or sv6 which put out 200kw
Sv6 swap would be far more than a 3k budget. Mounts, tailshaft, gearbox custom loom, exhaust, left hand starter conversion are all things to consider.
Rb25 long motors are 3k minimum.
A vlt manifold (150$) gtr 444cc injectors (300$) external gate and fab work to make it work on stock manifold (100$) t04e/3076 ebay special 100-300$ (I have a turbonetics bb and was 150$) nistune (300$) all the other money would be in your cooler piping and exhaust fabrication and dyno time. Thats only 1k in bits.
how much harder is it to turbo a a6 block is it worth it?
How much you Tharge Tobo put in my car
My car is Holden commodore VL 1987 pltease ?
Have you had much to do with rb30’s with dubble overhead cam heads? And would turbo selection would be the same for such engine
Bud not worth going DOHC head unless you want to rev it past 7000rpm and mKe over 500hp easily and go for the new gtx30/76 series two rated now for 750hp from Garret much more efficient and good for 30psi
Yeh mate done a few. Turbo selection generally remains the same and is always dependent on cam choice. If you retain vvt in the twin cam you can afford to go a little bigger in housing size over the sohc which can allow for more peak power. Either case you can still go 7500rpm before the rb30 rod bolts start to get unhappy.
Personally a lot of work for little gain imo. If you already had a 25 powered car it would be worth doing to get that extra .5L. But if you already have an RB30 powered car just leave it SOHC 👍
Hey mate. For a rb30 camshaft and aftermarket ecu upgrade, what are my options and brands ( none turbo)
Hal tech and Link ECU are two I’m aware off
Sweet vid mate. Ran with the A6 myself, check it out on my channel. RB30 26 head, forged etc
What about a rb20
Is a rb 20 in a vl worth putting a turbo in it.because of how heavy it is.
why na engine vtec engines are strong from factory. its coz they can rev high so u know its strong to be able to do that. so ehy they boost them
What are you talking about? This is not a Honda

Im currently looking at an elite 750 or a link g4x atom ecu what would you guys reccomend?
Adrian Morosin both great ecu’s mate. Link is probably more capable. But the elite is better value for money in my opinion with built in MAP sensor etc
Leprechaun Laboratory thanks for your input! Just out of curiosity as a tuner what would you chose out of the two?
Adrian Morosin very much depends of your end goals of your setup! The haltech is a little easier to navigate and a little more user friendly. So if you are interested in starting to poke around and learn to tune a bit yourself I would recommend the Haltech.
The other advantage is the 750 is capable of full sequential ignition and injection on a 6cyl. The Atom can only run a 6 cyl in Batch Fire/wasted spark.
For these lower end ECU’s i generally recommend the haltech. Once you get into the higher end ecu’s the Link capability becomes a real big advantage. But then things like Motec and Emtron are a step ahead again.
Another really good value for money ecu i would recommend is Adaptronic. Once again quite a bit more capable than Haltech, also once again not as user friendly.
Leprechaun Laboratory thanks heaps for your help! I think I’ll have to go with the 750 as it has the option of sequential fire and has more user friendliness as you said!
@@imperativetosuccess good choice. Although these days its pretty hard to choose wrong if buying a new ECU!
stock vlt ecu opinions ?
Okay if paired with the VLT injectors on a factory a8. outside of that they are not much use
Can be done, but Vlt runs a Knock sensor. A resistor can be put in place or just go a Nistune ecu tuned to your setup and will run heaps better!
Great info if the vid was 15 year old
Yeh all these engines from the 80's have changed in the last 15 years......
