Yeah i have read some... Its just that its so damn big, there's so many different conversations about what i wanna know its all just a little confusing... Basically, i've got a perfectly good RB30ET block with f**k all km's on it, im planning on puttin the R32 RB25DE head on it with all aftermarket bolt on's... I just wanna know whether the E and ET blocks are basically the same and whether i just need to use the RB30E spec pistons to get the appropriate compression ratio??? If not, what would be best???

If you are thinking about putting the head straight onto the rb30et block standard then it wont work. HOWEVER if you change the pistons to the NA spec then it will be ok.

The pistons in the rb30et are too low compression and the NA pistons should be used.

If you rebuild the rb30et block and put forged pistons in it to raise the compression up to the same for NA then it will be good.

Guys the RB30 vented coil pack covers are going to be cut soon any suggestions as to what is going to be on there would be great i have come up with at least a few say 2 or maybe 3.

"RB30 DET"

"RB30 DOHC"

"RB30 TWIN CAM TURBO"

"RB30 GODZILLA" for 4wd ones :dry:

"RB30 TORQUE MONSTA"

Maybe a "RB30 DOHC TURBO"

or " NISSAN 3000cc DOHC TURBO"

What did it say on the stock RB20/25 covers before?

r32 rb25de head stock with det valve springs big front facing plenum 80mm throttle body q45 afm. bottom end stockish rebuilt. shot peineed rods, and aftermarket rings, crank collar, either rb25 oil pump or n1

what would this turbo go like on it?

called a gt45

Inlet (Exducer/Hot Side) T-4 Flange 70.1mm x 82.55mm (2.76" x3.25").

*A/R 1.05 Exducer

*A/R 0.66 Compressor

*Cooling/Lubrication Oil

*Outlet (exducer/hot side) 4.25" V-Band

*Inlet (compressor/cold side) 109mm (4.25")

*Outlet (compressor/cold side) 86mm (3.38")

*Compressor major diameter 98 mm

my goal is 400-500rwhp. On a 20det modded manifold When would this size turbo start spooling and when would it hit full boost? 15psi. unsure of what exhaust manifold yet, either a 20det stock modded to fit the t4 flange or a whole custom mild steel one.

Can anyone help with some info on this? is this turbo 2 big?

Thanks

Too big, by a long way.

:D cheers ;)

PS; Shot peening used RB30 rods achieves almost nothing, spend the money on a set of ARP rod bolts

    • Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).
    • Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
