yeah wasn't sure they made a neorb20..anyhow to turbo an n/a engine, it is all in the naturally aspirated section (n/a) or search for my thread under green n/a r33, cheers hame

Simple, fit turbo(i would consider an r33 exhaust housing to bring it on a little sooner), fit some rb25det NEO injectors(ive got a set if you are interested) and take it to DR DRIFT, get him to remap the stock ecu to suit the turbo/injectors.

i just wanted to bump this up as its kind of interesting i thought, not looking to do it, just out of interest. there is a slight bit more torque, and with the NEO head no doubt it comes on earlier, but mostly it produces the same power with lower compression ratio (9.5 compared to the 10.2 for the R32 RB20, and 8.5 for the DET) so as far as chucking a turbo on it, it sounds like it could work well.

anyone have any more input?

Thanks guys, I am after the critical details such as ECU tunability? and I want to keep the NEO active if possible, any other info appreciated

i dont see a problem with it, if anything with its CR if it is 9.5:1, then it would be more boost friendly than the normaly turbo bolt ons.

THere isnt anything "active" with the neo side of things, neo is just the style of the head, it has vct but that works the exact same way as in the r33's so no worries there (and you wont need to touch anthing to do with the vct).

where are you from, i didnt think you could comply a r34 with a rb20?

dont blame you for wanting to turbo it though, i've got a rb25de neo in my r34... f*k me its slow as shit haha

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
