im not keeping the motor for long, thats the only reason im not doing it that way. the motor is just to get me around for the time being till i can build a 30/26 which is where my money will be well spent.

and even the way ive done it, you will all see it handle the runs and track days well ;)

If you wanted a cheap rebuild you should take the donk out , strip it and carefully check everything then only replace what ever is warn/damaged . You can't just hone it out and hope for the best, the pistons you used ( the second hand ones ) you should have measured them to make ure the piston to bore clearance is not to big .

Just because they came out of an rb25 don't think they are the same, don't forget they are graded so they do vary a bit, then you hone it as well .

You can't realy clean the bore after honing on the car you have to scrub it with soapy water to make sure you don't leave any honing stuff there that will wear the bore very quick . You can't measure the bearing clearances on the car the crank has to come out put on the lathe to check the runout to make sure its within specs .

If as you say the bearings were like new you would have been better of to leave them rather than change them and not check how much clearance you have there .You left the old pistons there and it was pinging so why not the old bearings? You should have at least pulled the oil pump appart to check for scoremarls and wear .

Feel free to pm if you want but this time do it the right way, believe me you can't cut corners and don't forget you will need a new gasket set and a new h/gasket dont use the old one again .

Some people do everything right and they still have problems, imagine when you try to cut corners !

Good luck with it ..

the pistons i used were the same dia as the ones ive got in there, the bore didnt increase in dia. by much at all, not even half a mm.

we did wash the bores out then blowed them out thoroughly. same with the crank.

the 4/6 pistons were replaced.

anyways, im leaving all decisions to my bro in law.

the matter is now closed.

I hope you didnt increase the bore size by half a mm, if you did the pistons would swim in there, actualy even a few hundrenths of a mm is to much ! I honesly dont know how you washed the block in the car.

      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.
