hey,

I just had my r33 dyno, and the dyno was stop cuz it started to ping (was only running 0.6bar). So its time for FMIC.

I want to do it right the 1st time so im going to buy a intake plenum alone with the fmic.

I was looking at the Greenline website and saw

Trust GReddy Surge Tank

(Intake Parts) ¥73,631

Intake Plenum. Suitable for use with TRUST or standard fuel rail and injectors.

--------------------------------------------------------------------------------

Trust Throttle Body Adapter

(Intake Parts) ¥7,363

Adapter to use factory throttle body with GReddy Surge Tank (Intake Plenum).

I was told i would need the throttle body adapter, is this ture?

and is this baiscly all i need apart from the ic?

thanks mike

You may also want to take it to a decent dyno shop, I have trouble believing you got detonation at only 0.6 bar, thats like stock boost (pluss a tiny bit). Why even tune it for 0.6bar, I mean add a bleed valve and go for 0.9bar (and you may have problems with detonation on hot days - but not at 0.6)

Just a thought - I assume you an exhaust and air pod ????

Before you go out and buy FMIC and Plenum, (I personally think plenum is a bit overkill unless you have a rebuild engine and ready to run a giant boost/high HP application)

do you make sure that your pinging is:

- not caused by merely heatsoak from the stock intercooler?

- dirty/stuffed plugs, or plugs with the wrong heat range installed?

- bad injectors (leaning out)?

- dying fuel pump? (not supplying enough fuel - lean mixture)

- stuffed AFM?

- blocked fuel line?

- stuffed engine (do a quick compression test on all cylinders to make sure)?

at the end of the day, I'd say go get fmic is good, but intake plenum hmmm...

not always needed if u had stock turbo and running under 1 bar. u might better

save the money for something else and get the greddy plenum till later. Many ppl on the forum can easily get 250rwkw with stock plenum, just exhaust, ecu, fmic and upgraded turbo.

hey thanks for the reply,

my car is running 100%.

The car has some sort of custum turbo using the differnt front end and the stock r33 rear end, also the car has a ebc set to 0.6bar (no spiking) i have exhuast (catback), ait filer, bov and r34 gt-t cooler upgrade.

But yeah the place i took the car too is very good place (not a backyard job) was done a ShootOut Mode Dynodansice (whoever u spell it) V4.

Dude - your car is not running 100% fine if it is pinging.

And also - just because your AFR graph goes up and down like that doesn't neccessarily mean you are pinging.

Pinging is an un-controlled explosion - a physical sound - not measured on a Dyno Graph -

You car might be pinging tho - we cant tell from here.

A front facing plenum won't fix pinging. Get your car tuned properly. Get a FMIC with a kit that redirects the air to your std plenum.

Put more fuel in

Get a bigger fuel pump

Retard your timing

There are lots of reasons that your AFR line is going like that

Cheers,

B-Man; the person who did the dyno run isnt a no-body and know his shit. He told me get fmic. i want to get a plenum for the simple fact that if i do change my turbo there is no point me doing the ic piping 2times if i go from stock to aftermarket plenum.

Also my car is tune fine, the dyno dude said if i got a safc II, it would be pointless he wont change my air, fuel ratio cuz they are fine not too rich and not lean. my timing is stock

Man I got 180rwKW out of a standard intercooler, and only had trouble with pinging on hot days when driving it too hard for too long (heat soak), and the boost was set to 13psi, so your figures are way off the mark if you cant tune it without pinging. My guess is that there is another problem with your car.

Im not sure whats wrong with the car, it drivers very nice, (and when i run 0.6bar and push it to limiter in 1/2/3rd gear i have no pinging problems) but on the dyno it started to ping at around 5500rpm in 4th gear :confused:

my ic might possible be ****ed its a r34 gtt cooler which is bigger than the 33 cooler so i through it would cooler better.

My 1st run i made 189rwhp (on stock boost 0.4bar) my 2nd run on stock boost also went down to 184rwhp (because of heat i was told)

The car was just done for a power-run not a tune

    • GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?    
    • So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.
    • Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?
    • Should have asked what is the car?
    • I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
