JDM_R32_R35 Posted August 12, 2013 Share Posted August 12, 2013 (edited) 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 Edited August 12, 2013 by JDM_R32_R35 Link to comment https://www.sau.com.au/forums/topic/430153-rb20det-specialists-only-question-no-rb2526-replies-here-please/ Share on other sites More sharing options...

PN-Mad Posted August 12, 2013 Share Posted August 12, 2013 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 Link to comment https://www.sau.com.au/forums/topic/430153-rb20det-specialists-only-question-no-rb2526-replies-here-please/#findComment-6967453 Share on other sites More sharing options...

XKLABA Posted August 13, 2013 Share Posted August 13, 2013 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 Link to comment https://www.sau.com.au/forums/topic/430153-rb20det-specialists-only-question-no-rb2526-replies-here-please/#findComment-6967560 Share on other sites More sharing options...
Hanaldo Posted August 13, 2013 Share Posted August 13, 2013 (edited) 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.

GTScotT Posted August 13, 2013 Share Posted August 13, 2013 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. 1 Link to comment https://www.sau.com.au/forums/topic/430153-rb20det-specialists-only-question-no-rb2526-replies-here-please/#findComment-6967586 Share on other sites More sharing options...

ianjb Posted August 13, 2013 Share Posted August 13, 2013 If you are pushing this much power, I'd suggest making sure your panel gaps are exactly factory spec. Talk to this guy, he can help.
