Hello

I have a r32 GTS-T

Currently I have the intake, full turbo back exhaust, intercooler and boost controller on the car.

I am about to upgrade to a rb25 turbo, a tuned Tomei computer that is for my set up with a GTR fuel pump, and a 25 turbo, I think it is a boost up tune,. Not sure how much of a boost up tune it is.

Will my stock clutch handle this?

Someone gave me a ACT 6 puck un-spring clutch kit. http://www.rawbrokerage.com/act-6-puck-un-sprung-xt-clutch-kit-rb20det-rb25det-630ft-lbs/

Is this overkill for my set up? Will this be uncomfortable to drive on the street?

Before you even worry about a clutch go and get a nistune instead of that tomei whatever.

You can't just go and put some random ecu in and expect the tune to be spot on for your motor.

Nistune is expensive here in Japan. Only two places does it. The place wants over 1000 dollars to tune it. From what I have read and been told on this forum, it should only be about 300-500 dollars for a tune.

The computer is tuned for myset up for a r32 gtst-t.

Since I have this clutch anyway, is it good to use or is it for high horse power and will driving on the street be uncomfortable?

No it's not. It's tuned for some other setup. You have no idea whether your engine will take the same amount of timing and you have no idea if your fuel system flows the same way as the car it was "tuned" on. Buy your self a TUNABLE ECU and give up on this cheap arse approach you seem to have.

"Since I have this clutch anyway, is it good to use or is it for high horse power and will driving on the street be uncomfortable?"

That clutch will be a miserable motherf**ker to live with. Buy a sprung organic full face HD clutch from some reputable vendor.

Its not a cheap approach, I came into these items. I was actually searching for a affordable tuning computer or maybe going to MINES.

I will probably stick with a Nismo Clutch, that was the plan

MINES = exploded engine. Do not do it. Expect to pay $2k for a decent aftermarket ECU and up to $1k to get it tuned. Expect these numbers and come to accept them. They are reality. That quote that you have for >$1k to tune a Nistune in Japan......Does that include supply and install of the board? If so, then the price is right.

No, that is just the price of the tune.

Why the bad rep with MINES? Ive never heard anything bad about them except their high prices here in Japan.

Are you kidding? They have a MASSIVE reputation for having too much ignition timing. That is probably more of a problem for Aussies, because 100 octane fuel is available in Japan and the Mines ECUs are probably set up for that, and we only had 95 for a log time, and only 98 now. But the real big problem is that people think that you can just grab a random ECU and stick it on your engine, with no idea of the relative merits of the ignition, fuelling, turbo size and boost threshold etc etc and just believe that it will work. What happens if the Mines ECU winds in too much timing in a certain area of the map because it was set up for a bigger turbo and yours is making boost there? Pinging? Detonation? What if your fuel pump is not as good as was expected when the ECU was mapped? Or what if yours is much better and maintains heaps more pressure at high load and rpm? What if your injectors are dirty, or have been swapped for something else and you didn't know? ETC ETC ETC.

OP, are you talking about going to the Mines shop and getting them to burn a custom EEPROM for your car? (This is OK)

GTSBoy is talking about getting a random ECU with a Mines sticker and slapping it in your car. (This is not OK)

      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.
