Hi Guys,

I recently moved from SA and I need to find a tuner that is trustworthy and in particular; knowledgeable with Nistune (RB20 ECU running a RB25DET, EPROM program/new features etc.) E85 etc.

I live in Springfield and work near Beenleigh. Willing to travel to get the best result.

Thanks in advance.

I currently am running 100% E85. But I'm thinking it would be more convenient to go flex in the near future. The United Race Blend E85 is another curveball (which will depend on price and them not running out all the time).

My car has been tuned without VCT. So the first thing I need is a tuner to tweak the tune with VCT on and then I can set the window switch at the optimal cross over. It's so doughy down low as you can imagine.

To compound matters my exhaust manifold is slightly cracked. So I’ll probably get a 6boost (high mount) so new pipe work and maybe turbo? Waste gate? The list goes on and never stops ;)

Got my R32 gtr with nistune done on E85 at EFI, they seem to have done a great job and the car runs well. So plus 1 for EFI I guess.

The 107 octane race fuel variant from united seems interesting, though I don't think i'd go for it as it'd limit the areas you could refuel way to much for a street car I think. Also because i'm getting valve float and I wouldn't really gain much more top end with it.

That being said, would be great for more dedicated track cars, or in a flex setup if you were content to spend a lot of your time on 98.

What switch do you have for VCT with RB20 ECU? Something external or a tweak?

If you want a good starting point then turn VCT on at 1200rpm and off at 4800rpm. It might not be perfect but will be much better than what you have and probably a bees dick off optimal.

      Stock rb25det neo questions

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
