hi, just bought an rb25 turbo and want to bolt it to my rb20. i know it is a direct swap and that i need the rb25 elbow.

what i want to know is, when i do the conversion, do i have to take the manifold off? cos if i didnt, this would save me a lot of money for the gasket.

did a search, didnt have exactly what i want. even went through all 17 pages of old posts :P

no you dont have to take the manifold off, as the turbo just bolts straight onto the manifold.

I know this for a fact as i have an rb25 with rb20 turbo and when i went to change the rb20 turbo to rb25, i didnt neeed to take the manifold off

cheers man, my friend just told me that when he did it he had to take the manifold off, but he just said that he only did it to make it easier, but he did have to buy another gasket... was it much of a pain in the ass to get the turbo on/off with the manifold in place?

Its not a hard job at all I did it last weekend. It is just very time consuming as some of the bolts and stuff can be a bit tricky to get to. helps alot if you have the right tools.

How much did you pay for the RB25 turbo? Reason I ask is Ive just bought an RB25 NEO turbo and am going to put that on my Stagea and sell off the standard one.

Im not too sure if its worth selling, due to being in the 'defect-state of australia' but What are they worth? (I believe its in good condition, been on 9 and 10spi since its been in Australia for the past 12 months, and was stock for 50000kms in Japan - probably)

They say you dont make friends with salad... But in this case i will help....

I have done this swap more then any other.... Its easy about 3 hours of pure fun....

Everything bolts straight up except the top oil feed.... You will need to bend it slightlly to fit.... But be carefull not to bent it too much as it will crimp the line down and reduce flow... We dont want that....

Apart from that its bolt in and out.... My 3 hour estimate is me with 3 breaks of 10 minutes for smokes and coke......

    • 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.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
