Hi, Just a question regarding tuning.

RB20DET specialists only no RB25/RB26 replies please

I want to try 800kw on my rb20det I know it sounds stupid but, has anyone tried this before?

I know it needs a lot of mods but, has anyone achieved this before??

Please no reactions similar like these:

RB25 and/or RB26 is better.

Why not swap the RB20DET for a RB25/RB26.

RB25/RB26 is better at this power level

Why not buy a R32 GTR

It would not be economically

Many thanks

In all seriousness we are talking 1000hp... I believe that to be a power figure that requires an experienced engine builder to produce an engine. That being said I also do not think it matters what mo

Doubt anyone has tried.

No going to be bothered searching if anyone has.

But you'll require 10,000+ rpm

Something upwards of 50psi

And a lot of strengthening, and flowing of all components.

And it would be a complete dog to drive anywhere except down a 1/4 mile

It can be done, it just depends on how much of the RB20 you want use

If want want the use 20 piston rods crank block and head then no your shit outta luck

But if your happy to swap them for say 30 block crank pistons and rods and a 26 head then yeah 1100 hp from a RB20 is easy done

OP, have you considered swapping to an RB25/RB26?

These are better.

Why not swap to an RB25/RB26?

RB25/RB26 would be better at these power levels. I think you should do it. I hope I was able to suggest this to you before you went ahead with the RB20, because RB25/RB26 are better. At these power levels.

Or buy an R32 GTR.

In all seriousness we are talking 1000hp... I believe that to be a power figure that requires an experienced engine builder to produce an engine. That being said I also do not think it matters what modern engine you start with... To get it to 1000hp would probably be a similar amount of work regardless.

Therefore OP should take his RB20 to an experienced engine builder and ask them to produce a 1000hp engine capable of over 10,000rpm. Then OP will simply need the manifolds and a turbo to suit.

$100,000.00 later and it will rip good skids.

This must be with the Motec system and a stand alone fuel management system?

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
