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?

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
