Hi all, i recently have done a few mods to my r33,

- high mount to4e

- 720cc injectors

- 040 fuel pump

- sard fpr

- greddy ultimate

- greddy plenum

- fuel rail

- new cooler piping

- turbosmart boost tee running 18psi backing to 14psi.

it made 220kw at the rears on 16psi at 6200rpm(limiter set at that, which im pretty pissed about, im thinking its the turbo not making the power, but i need a workshop that can tune it better as i aint 100% happy with the power and tune, any thoughts?, ive previously had an s13 with an rb20 which had link ecu, to4e, fuel pump, ignitors, cooler, exhuast, 15psi that made 320hp, give and take a couple of hp due to different dynos, but my rb25 isnt making the power it should?any ideas will be muchly appreciated?...thanks. Ive heard about Matty Spry if anyone know his contact details or what his workshop is called pklease let me know thanks

Please talk through past experience, thanks

G'Day GHO57,

Im the tuner at EFI, I dont normally post on here as that is Ricks (whitey) thing,

The power that you are making in very respectable with a T04E.

One thing to remember that a T04E does come in may different housing and wheel trims and sizes.

Your 220rwkw works out to around 300rwhp which on 16 psi is pretty good.

Its a little lower than 35R sort of power figures with an older style turbo you have to expect that.

I would maybe ring your tuner and ask why the rev limiter is set too 6200, as this is pretty low for a 25. If the power is dropping off then maybe look at camshaft timing as this is a good give away for horsepower falling early.

You say your boost controller is hitting 18psi, then dropping to 14 psi? Do you mean its spiking to 18psi then dropping to 14psi higher in the rpm? if this is the case, Its sounds like you may have a compressor out of flow or a miss match on the exhaust housing side e.g. too small exhaust housing.

How is the drivablilty of the tune? does the car start and drive well? does it use a excessive fuel when not driven hard? These are things you have to take into account other than power figures.

Id give your old tuner a bell, and just ask them. They where obviously good enough to go to in the first place, and they may have explanations for all your questions and even options on how to remedy any issues you have.

Failing that Matty can be contacted on

All good common sense there.

One of the big ticket items on your list is the greddy plenum. Just because you paid plenty for it doesnt mean it well net you a massive power gain.

At that mod level it would brobably do bugger all and may even cost you some down low squirt.

thank you to all that have replied, fuel economy is better than it was stock, im getting more km's out of a full tank of 98optimax, and with the mods im fairly happy with the consumption atm, yes i am aware the plenum may not do much in power gains, but for future plug changes, more spacious room in the enigine bay i went with it, its a genuine greddy plenum yes it costs big bucks, but hey its not something ill be thinking of changing later on & i dont want a chinese brand that doesnt fit or needs modifying to fit, but the turbo on the other hand, yes but a standard turbo could make 300hp atw, dont understand why a t04e isnt capable especially on 16psi making more power, yes it spikes to 18psi the backs on to a steady 16psi, cheers for all the info guys please pm me a workshop that is able to help me cheers.

If you have good coils you shouldn't need to gap your plugs down to 0.7mm - all you're doing is hiding a weak spark.

Try opening them back up to 1.0 or 1.1 mm and see if that helps your idle, obviously if it starts breaking down under load at higher rpm though (at 18psi and not insane power you should be right if the coils are in good nick) you'll need to either close them up a little bit or invest in stronger coils. IMHO it's worth looking at a set of LS1 coils or something similar if your ECU can drive them, it doesn't sound like you have an issue with upgrading with an eye to the future :(

thanks for that, yeah the coilpacks are brand new, i dont know why but "they" said to me that i needed a cooler plug(which is correct for higher boost levels), but yeah im taking it to get it dynoed again on the 15th-08-09 so it will be interesting to see what is stopping it, cheers all.

Big Thanks to EFI PERFORMANCE for their help so far. Appreciated

      R32 GTS (RB20DE) Injectors Replacement

      By MBS206 · Posted

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      By AnimalGarage · Posted

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
