Why would you want to 'do up' a NA RB20?

im just curious and want to build a good engine up from scratch then when im of my p's i will be bolting on the turbo and therefore will have a good engine to handle the whole setup

and thanks for mentioning RB26 injectors

and remeber reading somewhere about 26 cams too. But m not sure about the solid lifters in 26's

thanks for the REAL input

Why wouldn't you?

For a lot of enthusiasts out there turbo is out of the question and a lot of people also love a tuff NA.

Sorry can't help you with the info though.

yes but cubes are everything, Na engines require capacity, why hamstring yourself with a 2ltr when you can run a 3ltr with 26 head. Run comp up to 11:1 . E85 and off you go.

or at least run the RB26 crank and rods in the rb20.

Depends on how much you can get a crank for......if your trying to do this on the cheap i suggest you leave it as is as splitting an engine to change stroke will require machining and parts, at least rings, bearings and gasket kit. Replace water pump, timing belt, camsafts & gears etc etc. if you then are paying someone else to blueprint the engine you will be looking at atleast $1500 in labour. I reckon to stroke RB20 using second hand parts ie crank and rods, machining and other parts + labour to build.......$5000. Cheapest option would be to get a 3litre and put you head on it.

    • This car has run before on this z32 ecu can get the part number for you, I have tried with no AFM it didn’t change anything, I compression tested today 140-150 across all 6 cylinders, also set fuel pressure to 43psi. The only weird thing was cylinder 1 plug was black and fouled other 5 cylinders were just wet with fuel. Spun cas by hand and confirmed injectors are clicking 
    • Since you came here to ask for help, have you thought about answering our questions, that might help us lead you to why it was skipping, or have you given up on getting advice?
    • A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.
    • The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
    • So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...
