Have a look at the RB25 dyno results page and see what mods people are running to achieve your power goals -

You're not going to do it with either of those. Injectors too small (and too old and shitty). Coils are shit. Upgrade to at least Splitfire, if not Yaris coils or R35 type coils.

Fuel pump is probably too small too.

if 500whp (373kw) is truly your goal, your fuel choice also matters which can affect the turbo you choose to run.

As far as ECU's go, find one that your tuner will tune.
No one does or trusts online tunes for cars like these. They're pushed too hard and are too individual (even with same list of mods) to get anywhere close to trusting a tune from another car.

You'd need so much gear to convince yourself the tune is actually okay, to the point where you could just DIY the tune from that point.

All fail whale items, please don't get any of them.

      I am well aware as I did rant at him to buy a MX5, buy the 2.5 before he DIY'ed it, etc as well as do things to the holden. He will obtain a ND. It's the best of both worlds. They look great in person, definitely the best looking one. Just a matter of time now.

      This sounds like someone who would have owned an R33 in their past... It's okay, I'm 100% picking up what you're putting down Mark.

      Jacks that fit under GTR lips that can reach the subframe?

      By MBS206 · Posted

      Just back on what was raised about jacking off the the tow/tie down point on the front of cars. I've used it plenty. I've also watched it on a car where you could see it move the front end of the car. It was like the front end/whole car being tweaked and twisted a bit. I will say, I struggle to find good jacking points on MOST cars. The ones that have good points, I then normally struggle to find a jack tall enough to make the car change height!   One of my go to points for either the jack, or the axel stands though, is either a suspension pickup point, OR a subframe to chassis major bolting point. I actually think its the subframe on my R33 that has a bit of a bend in it, from being jacked in the middle too. However, it could have been one of my many other cars I've had over the years! Or it could also be the from me jacking it up, and the fact the top of the front radiator support isn't there, so it can allow the front of the car to move and bend etc.
