Im being told that rb20's make power easier than 25's

Also that my mate has 270rwkw from his rb20det...

There was a thread created a while ago for people with rb20's making 260rwkw or more and all seemd to have trouble getting there

Just to confirm rb20's make less torque, have more turbo lag and as a genral make less power if the mods where the same for an rb25

?

No. A mate of mine has basically the same mods on his RB20DET as I have on my RB25DET. We both have upgraded turbos on stock manifolds, stock motors, aftermarket ECU and fuel system etc.

My car is tuned on BP98 at 17psi and makes 301wkw, same dyno his car tuned on 30% ethanol and 21psi makes 295kw. He gives me a bit of a run for my money on midrange torque - probably more to do with extra boost and better fuel, but his falls flat at 6000rpm and mine keeps making more power. On the same fuel and boost I have roughly 50kw on him, better off boost torque and way better midrange.

No comparison.

Il grab the list of mods and let you guys decide

apparently stock injectors, stock ecu.. 3incj zorst, fmic, 18psi, flat top pistons, to4e turbo and a tune making 256rwkw

il update if there are any mods i left out

stock injectors would not let you produce that much power.

I've owned both RB20DET and RB25DET, for someone to say RB20DET makes more power easier than RB25DET mod for mod, they must be on drugs >_<

Mod for mod, the RB25DET will make more power easily, why on earth would R32 boys be putting RB25DET motors into their cars? Go figure!

    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me  
    • That's my life. Past-Duncan has a lot to answer for
