Sorry to be silly ! But are you reading the boost of the ome gauge ?

I put a blitz return flow fmic and a 3inch JJR bell mouth on with a boost controller. It would spike to 14psi then it would drop down to maybe 12 11 psi.

I ran that for a year and it was all sweet !

Many would advise not run more that 10 psi !

I wouldn't buy an EBC to raise the boost 1/2 a psi!! Not unless you can get one super cheap second hand. The only benefit you will get from fitting ANY boost controller at this point will be to keep the wastegate closed as it is coming on bost, which will make it feel MUCH faster even if it doesn't actually have any more total power up top.

12 psi is not risky at all. If it spikes up there every now and then (or realistically, even every time it comes on boost) you're not going to damage anything. The turbo will be fine - it won't shit itself at 12 psi any more than it would at 10. Sure, it could shit itself, but they're like playing Russian roulette anyway. The ECUs on R34s are a lot less emo than on R33s. They still tend to get well rich and retarded, and if you try to run 12 psi boost all the way to the top end then it might start to feel a bit ragged and slow. I have recent posts (in the last week or so) where I describe setting up my boost controller on my Neo and what it felt like at various boost levels. My physical mods are similar to yours. Good exhaust, FMIC, standard R32 airbox but opened up at the inlet, Metal turbo intake. Meaning that your ECU's thresholds of emoness should be similar to mine.

You need to Nistune your ECU, get the turbo highflowed, get some injectors, a fuel pump and a Z32 and tune it up towards 250 rwkW to get any better results than where you are now. A tune on the standard ECU and fuel system (maybe upgrade the pump for safety) will nett up to 210-220rwkW on a Neo, which is pretty good, but you keep the risk of the turbo going poo.

Nistune prices? See the Nistune website perhaps. It really is that easy.

Also, I am tempted to send you to lmgtfy.com for my recent post. I will have to search for it. If I have to search for it, then you could just as easily seacrh for posts by GTSBoy with the term "boost controller" or similar.

lol!Next mod has to be shift kit for trans. They take a crazy amount of time to shift between gears. First mod for any auto should be shift kit.

      Returning after a long time!

      That's awesome. Fully serviced/full log book history for one of those cars is super rare from what I know. With JDM's like Skyline's, Supras, are quite hard to find one with full log book history. S15's seem to be somewhat of an exception, at least the spec s australian delivered models.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By DRoc81 · Posted

      Hey all, It's been a bit since I have been able to update.  I pulled the fuel pump, first off it was a "universal" pump and the strainer was very clogged, and it was folded over on itself.  I replaced the fuel pump and all is well....  No more stalling.

      That's convinced me I'll bump up the G30-660 to 770   Any idea if the difference in boost pressure? Cheers

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Hey guys so turns out this project is going to be much bigger than I thought haha but I've done some my homework and have done a few panels on my car, but one part I can just not visualise is this. If I do a spot repair and I put filler in a dent for example and sand outside of the repair with 320 grit lets say so the primer can stick as I will only put primer on that repair and the surrounding area and then repaint the whole panel. Don't I need to make sure that I don't put primer on the old clear coat? I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down, it's still shiny. I thought putting paint on clearcoat or primer on clearcoat is a bad idea because it won't stick. So in this scenario it's a bit different to mine but imagine someone doing a spot repair and only painting that small section of repair but the new paint is landing on the old clearcoat. What am I missing?
