So thinking to put a rb26 on a rb20de. I think the bore and centres are the same, but i don't think bolt sizes are and the valves won't like the smaller bore.

At the end of the day, do you think its worth it? and why?

Thanks.

Well, it can be modded to fit, the topic isn't to be told what i shouldn't do. I plan on keeping my NA off my P's and keep it as a daily driver untill i get sick of it, and the idea of 140-150KW RB NA sounds good to me.

Just want to be different.

How do you intend to get this sort of power?

The RB20 is a much smaller bore than the RB26. So the combustion chamber of a RB26 is considerably larger than the RB20's. The piston at TDC will be like a dick-in-a-bucket fit into the chamber. The thing will have such low compression that you might be lucky to even start the engine.

And the RB25 bore is the same as the 26.

a 140-150kw would make an ordinary daily driver. a stock or mildly modded turbo skyline would be a better daily driver.

You do realise it is a modified motor, and therefore illegal - be it N/A or turbo makes no difference.

mohsen don't encourge him... this is why i hang out here to prevent stuff like this from happening. read up on gregs thread with the rb30 bitten end with a 26 head. thats the ultimate rb skyline natro you can make.... and as a daily i duno if you'd really enjoy driving round in a camed up natro just for the daily grind.

if you wana do.it do it, but its a lot of $'s for the sake of being different.

    • Hey all, I'm sorry if this has been discussed before.  I have a 2008 Japanese import V36 coupe with nav but without Bose. I bought one of those AliExpress android screens, which for the most part works really well.  The only thing that doesn't work is the air con controls (well sort of) and the factory reverse camera.  The AC can be controlled fine but it doesn't report the change in temp and mode to the screen, and the volume knob/other audio controls from the panel don't register on the learning app.  I am pretty certain that the problem is the difference in the head unit between base model (Nav but no Bose) 2007-2009 coupes and anything after 2009.  Mine is the one with the blue connector all the way to the right as seen in this forum post:  The reason I think this is there is one wire left over that doesn't fit anywhere on this head unit, or in the factory screen which also uses different connectors to more recent versions.  I've seen the upgrade from OWC, and have sent the guy a message on eBay but no response yet.  I also don't particularly need the whole kit, just *maybe* an adapter for this one cable.  Did anyone else here have the same problem, or have any insight about what I can do to get this working?  I have been in contact with the seller but all they seem to be able to do is ask for more pictures and videos. Minor edit to add:  I have been researching and found a screen on Aliexpress that actually specifies my head unit in the listing, so these things do exist.  I will contact the seller to see if the wiring adapters are interchangeable with other screens.   Thanks in advance!
