Ye i plan to get an overlay (if my old tune is still on the tuners PC).

Havent got anything in my hands yet as it was just a setup without even a tune (factory ECU still)

I wont be fixing that wont be for a month or two yet, the GT-SS setup feels stronger everywhere.

I think its as much the turbo choice as the motor, being 26's are much nicer than 25s.

A setup that did feel strong was a GCG hi-flow R34, Bass Junky's/Petes car.

That felt similar to the GT-SS setup i have now. His setup was much better suited to the 2.5ltr.

Doesnt have massive top end, but the midrange is sensational.

This is a GCG manifold with at GT35 on an RB26.

I am looking at getting the gcg high mount manifold too, these are the pics i was sent.

In these pics it seems to me the pipe the gate mounts off goes towards the front of the car and not the rear, and im not 100% sure that is right.

Do you have and pics of your manfold BOOSTED? Also any reason you went the turbosmart gate and not the tial??

cheers

wow Dave your car has certainly gone through some changes since the start of 07!!

I'll certainly be following your progress, as this could be my next move next year!

Keep us up dated mate!

Cheers,

Chris!

My RB26, GT-SS setup feels heaps faster @ 250rwkw than my RB25/GT30 setup did @ ~280rwkw because there is power everywhere.

That'd have to be at least partly due to the difference in mass between an R33 and R31 chassis though? Weight counts for a lot.

That said, having a little less power spread over a wide range - rather than concentrated over a narrow range will make for a better thing all round. Matter of interest type question: what sort of useable rpm range does the 26 with GT-SS work over?

While the 26 is definitely spec'd overall better than a 25, depending on the power level I think there's a good argument for having something with VVT. Not flaming something up, just commenting that the 25 isn't a dog by any means. The 26 though, is a better base platform. :P

that looks pretty nice, id just be worried bout the cable ties on the wastegate heat rapp near the top :S

It does look very tidy overall. Good effort, and I'm especially interested in the work done to control/contain heat. I'd think the cable ties are very temporary, and we'd see either tie wire or a clamp of some description take its place before installation.

Looks like you're going to be aiming for some fairly serious output there Dave; no longer a daily drive proposition? What are you doing with management systems?

ECU is Power FC,Fuel system is Nismo pump and Nismo 555cc injectors,still stock ignition.

And no the car wont be my daily driver anymore,mostly used as a sunday driver and track day car.

lol never thought i was going to take it this far.But the car has turned into a hobby.I dont drink,smoke or gamble so i have to spend my money on something :P

HR31 and R33 almost come in the same actually.

Im 1400kg's without me in it.

R32's were 160kg's lighter as you can see when you put the two cars next to each other.

Not a lot of 'refinement' in the 80's im afraid. Everything electrical is huge and chunky compared to further models.

eg, my powersteering pump was 2x the size of a R32 GTR one (both hicas) lol.

Oh the 25 isnt a piece of shit. But if you had a choice, you'd just get 26 off bat.

      Mistakes were made, my R34 Story

      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.
