    highflow + injectors + fuel pump + fmic + nistune is the cheapest bang for buck in my opinion. probably look about $1000-2000 for the turbo depending on who does the highflow and whether it is ball bearing or not, and all the rest would be a few k all up once tuned. Don't forget a clutch when you fry yours and new tyres and susp to put it to the ground, all adds up pretty quickly.

    You could possibly make more power with a retune, but without it you should be fine. You've just increased your heatsoak capacity so on a hot day it should be less likely to ping due to lower intake temps. I wouldn't bother unless you want to up the boost now that you've installed it.

    Interesting, so it is fairly linear and should be reasonably accurate doing this? I thought it interpolated the values, eg 7500 and 8000 points, if you are at 7750rpm it picks fuel and ignition half way between this, if your last value is at 8000 and you rev to 8500 it will keep linearly interpolating the values so it will inject more fuel still? might not be what you want but it won't hold flat surely?

    open the ECU up and see if its been chipped, I know my rb20 had a mines chip in the ECU, advanced the timing massively and was way too rich, basically was running on the knock map permanently and very rich, resulted in worse than stock performance.

    looks completely negligible, the actual power and torque curves are almost on top of each other, it is only noticeable in the boost curve. 15-20hp is nothing to sneeze at, looks like a decent improvement for not much more.

    only thing is standard manifolds etc have no provisions for a stock bov, might be easier to fit an aftermarket one with a plumback attachment. I know the rb30et didn't come with a bov from the factory either. It isn't a huge issue, just comes down to noise and making it easier to tune on gearshifts.
  7. Rolls
    no its not bad for the turbo, but a recirc makes tuning slightly easier and will make it a lot quieter if that is what you are after, atmo venting will just be even louder and more annoying. if you get anything adapt a recirc bov into the intake.

    R33 ones are 370cc from what I know and they max out around 210-220kw.
  9. Rolls
    he is aiming for 380kw though, certainly not low, but not some 500kw monster that needs it to get the power.
  10. Rolls
    I would argue $5k spent on awesome semi slicks and rims would be less boring!
  11. Rolls
    i would seriously consider my suggestion unless you think youll be aiming for 400kw+ in the future, below that it helps but the money would be much better spent elsewhere.

    In that case I would push the turbo to its limits before looking at water meth, very easy to make 300kw before then, it is just extra complexity that can go wrong and if it does (pump breaks etc) it'll fry your motor right there and then. same deal with water to air, good if done properly, but a good air to air is good enough most the time, if its done badly then w2a can be worse due to bad heat soak.

    I think I am biased because I used to own one, but like most things you can find some love for it if you see it often enough, I like the sharp lines and other cars from that era as well.

    if you honestly got 11/100 around town then you must have had a very well sorted tune and driven it very easily. the 13 I get is peak hour driving everyday with a lead foot and 240kw, I think it is pretty damn good.
  15. Rolls
    water meth can be good if you are limited by ignition and intake temps, but if you haven't maxed out the turbo yet then I wouldn't bother, you will probably find the limits of stock pistons and bottom end before you need water meth. Also whilst it works well if you run out mid boosting say good by motor. I would consider E85 before you try water meth, E85 means more ignition and more boost and more power!
  16. Rolls
    I actually think they look better lol.

    product placement.

    people who say that are retarded, you can have 500hp and still get great fuel economy, the two aren't exclusive, you spend about 5% of the time on full boost in a street car so you can retain your 13L/100km and still make massive power. You save what $500 highflowing injectors? you'd make that back in a single year if you are using 2L/100km more and driving roughly 450km a week, also you'd get a better idle and cruise.
  19. Rolls
    sounds too dodgy to save a few bucks, you want them all flowing the same and a good spray pattern if you want a hope of good economy.
  20. Rolls
    stop being a stooge and buy proper tyres, what is the point of getting 12" rims otherwise?
  21. Rolls
    8kg is absolutely stupid, not even v8 super cars run spring rates that high.
  22. Rolls
    i think r33s look ugly as shit personally. 32 or a 34
  23. Rolls
    it is a scam and just a cheap capacitor, I doubt it would do anything at all.
  24. Rolls
    Im interested in how much bigger you can get them and whether the flow characteristics are a compromise over proper sized injectors.
  25. Rolls
    rebuild it stock and put the $5k towards something that will net better returns. or just get a second hand head and save even more money, that is what I would do. hell you could get your entire car resprayed for that cost, proper jap forged rims with semi slicks etc.
