Can i ask what EMS computer your running. Is it the Stinger?

If so how are you finding normal driving as far as throttle response and fuel economy. I dont know if the Sitnger can run closed loop, i know the Microtechs dont.

On paper the EMS seems a little down on functions, but if only being used in piggy back it may be ideal.

I would appreciate the feedback as need to get a computer in the next two weeks for my RB20DET

brendanf,

nice pics of the engine bay, looks similar to mine, I would suggest though that you do the pipes to a from the turbo, I did and it made a big difference, plus looks much better. It probably won't give you much more top end power, but the torque will be noticeable.

sidewaymambo,

Yes the VVT we are talking about is actually NVCS, but everyone understands what VVT means.

See'ya:burnout:

Re Throttle response - no problems there. Re Fuel Economy - has gone down, but we are working on that (approx 300kms per 50 litres) ~ 17L/100kms. I reckon it is running too rich because of axhaustr smell and black crap that spew out of exhaust when I dump it... But when on the dyno the A/F rations are perfect... I'm taking it to another dyno in 2 weeks for a compare......

Hi again Brendanf, engine bay is looking good. If you dont mind me asking, where did you get the plenum? What sort of figures does is flow? Did it come with a throttle body, or will the stock one fit up? Does it come with a fuel rail? And if you don't mind, what did it cost?

Something else you could do that you will probably find will help, is either wrap your dump or get it ceramic or HPC coated - this will help with scavenging and also help keep underbonnet temps down. Also if you go ceramic coat, you could probably get your coola to plenum pipe and turbine housing done at the same time, as they usually dont charge by the inch like HPC do, and it probably wont cost you much more to get them done at the same time.

Whatsisname, did you actually do before and after dynos on the cam gear and thermo fan? Ho do you find the temp regulation of the thermo fan? Is it as good as the stock fan? Are you still running the stock radiator?

Hope you dont mind all the questions

Cheers

Steve

yeah I say the plenium looks really good I like it alot not what i was expecting.

consider the cams as a good option as sydney kid suggested you might even be able to got the 260 or 264's there are plenty of kw hidden in your current package no need to change turbo. an the 300 klms to 50 litres isnt that bad fuel economy.

sound like a good result now go to the tracka nd run a number :wave:

If you are really looking into cams..maybe 264 degree is a good setup, because consider the lift and duration should help on your turbo setup. I have not done it, however did talk to someone who have similar setup on TD06..I'm in process of chasing the Tomei cams..264 set (in & ex), the in comes with NVCS should able to look after the mid and low torque...my 0.02

Steve,

Hills Motorsports in Castle Hill did the Plenum - all the origianl idle contol etc is retained. Not sure what it flows, Mark from Hill worked all that out - he told me about volumetric displacement etc etc, (ent over my head a little to be honest. He reckons that the with std plenum one of the cylinders (cant; remember which) gets lower flow than than the others, but with this one, plust the added volume, all cylinders get right and equal amounts of O2.

The throttle body if of a Ford ( can't remember which model) Stock TB won't fit as this one is bigger - But I spose, this could be modified as it is a semi custoem jobby - Mark has the templates for this on all sussed now - It's made out of aircraft grade aluminimum and is quite think...

Standard fuel rail is retained as my injectors were hi flowed to 610cc - so all that stayed in place.

Thanks for all the replys guys - looks like cams is next on the list...

Megs - yep, soon as I run, I'll post the time...

Cheers,

Steve Grand Master

Thanks brendanf, do you have a contact number for Mark, or an e-mail?

Did you manage to find out how much they charge for a highflow of the injectors? Are they doing the job OK? I am not sure wether to go high flow or new injectors, so just checking out he options.

Cheers

Steve

      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.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
