Fmic And Exhuast

[gttiwanna]

how about this exhuast restrictor plate i hear about on only r34s aparting it goes on the car just after the cat to make backpressure?

[GTSBoy]

You're the only person that I know of who has ever spoken of it.

[gttiwanna]

Lol I was googling the same problem as mine and I came up with

This idea from a couple of forums lol

[r34unit]

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 !

Reading comes from a defi gauge

i think i am going through something similar. i just had a full 3inch split turbo back exhaust installed.NO BOOST CONTROLLER.but i am already boosting .65 bar(reading of the stock gauge but pretty sure its that).

is that normal?

[GTSBoy]

That's normal. A decent exhaust will often raise boost to about that much (it's 9.5 psi, by the way, which is a pretty good spot to be. You don't want much more than that on a standard ECU.)

@gts boy i was planin to put on a ebc and boost it upto 10 psi(had a drive just now).since its almost there should i go ahead with that mod?will runin it 12 sometimes be too risky?

my mods are full 3 inch xforce varex with split dump and k&n drop in filter thts it.

[GTSBoy]

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.

@gts boy can i get the link to your boost setup post?

the ebc i m looking towards geting is a gizzmo.

i have been researching about nistune but cant find any prices.

i am an auto btw and i dont have fmic.

any sugestions on my next mod?

[GTSBoy]

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.

and ultimate fail would be asking what lmgtfy.com is. Don't do it.
