VL turbo is an RB30DET (correct me if I am wrong).

So, if the models go the same as the other RB range, non turbo would be RB30DE...

thats what i thought, i thought it would be rb30de

but apparently the rb30de is something completely different....

the picture below is a rb30de i believe

ok guys let me set a few thing straight

the rb20 head doesn't bolt straight onto the rb30 block, and it doesn't even have enough flow anyway to do so

theoretically an rb30de is an rb30 block with an rb25de head on it

people put heads from rb25/26 on rb30 blocks, you can't from the 20 without modding, but why would you anyway it's too small

Power is close to limited around the 350rwkw mark for the SOHC RB30ET (without going nuts on it in the first place). To get over this the DOHC heads from the RB25 and RB26 (even though I haven't seen a 26 on one as yet in real life). But in saying that cams are important.

Either way, you can make plenty of power with the SOHC RB30ET head, but if you're aiming for the 400rwkw + while allowing the engine to live a different head will be required along with selected cams etc etc.

    • I'll just leave this with, holy shit, those cars at work are awesome, and this will look wicked!
    • Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...
    • Do you have any before and after photos? That's $200 just for the hydro blasting?
    • It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
