So what happens with the variabel valve timing? You just lock the timing at the base setting?

Curse you ppl for turning your back on the RB20, Rb26 i can understand...but RB25. They are the enemy i tell you , the enemy:rant:

LOL...follow benms' setup and in an R32 and the thing will be loads of fun. Id say you wouldnt even have to bother with a turbo upgrade for good while:) There are a few R33 boys running high 12s with std turbo....

hmm i dont know wats done to my rb20 than.. maybe just a funky dyno..(more than likely)

im pushing out 180-190ish rwkw on stock boost with just a custom exhaust (made by a mate of mine) and a rb25 turbo(yes.. stock boost 7psi)

my fmic is goin on in the next few weeks along with a new clutch and also timing belt is getting done

I didn't know that you have to give the bank an invoice for everything you are going to buy with the loan $$$.

Jeeze they have to be a pain, although it is good coz some idiot could say he's buying a car and then leave.

Car will be going into mechanics on Monday 24th January and will be up and running early Feb.

take it easy

RB25s in standard form (not talking about the neo engine here) have never stood out to me, i've had many friends who have busted rb25 engines with minimal mods.

Sounds like your friends are doing something wrong. There are people getting >300rwkw on stock internals on a non-neo RB25. Steve for example .

hi roy,

everythings been going great, I have taken the car to my usual mechanic whom i am good mates with anyway. Rather than paying $2500 for everything then another $500 or so for power fc tuning im looking at paying just under 2k including the power fc tune.

My only stuff around is locating a speedo drive from a gtr to fix the speedo problem.

Will get it back this week, with power fc tuned, 3" front pipe, 9psi low boost and 13psi high boost.

Im itching to see what power it will make and how it will feel on the road.

Take it Easy

Mark

    • 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.
