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:

meggala

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,

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

    • This might be true if you live in NZ but I can't see how this could be true for us locals here.  I've found the customer support for Haltech to be absolutely amazing. I've turned up to Haltech and spent entire days with their tech support guys, they've even helped me with wiring dramas that had nothing to do with their products.  They have the best customer support of any company I've dealt with, I can't imagine how my experiences with them could possibly be any better.
    • If you want to do a single throttle body conversion easily, you won't need to pull anything apart. Take the linkage from your throttle off the linkage controlling the ITBs. Now open the ITBs wide open, and lock the linkages in said position. Now add a single throttle body onto the front of your inlet plenum. No it's not ideal for the last nth of a kw, but it'll be a lot better than what you're already trying to do...   PS, ITBs can be so damn hard to tune from, because roughly 20% movement in a throttle body equates to a change in roughly 80% of its flow (Hence power). When you add up the flow limitations of those small throttle bodys, it is a LOT higher than that of a single large throttle. Hence, TPS is very very sensitive with them, and you do a LOT of work with sensor fusion, and some Maths behind the scenes to make those blends nice, and be smooth.
    • Yep, when Haltech purchased Adaptronic, and all of the Adaptronic staff, including Andy went with it, it took Haltech to the next level. Haltech wanted Adaptronic as they wanted things like Andy's fuel models, and some other IP, AND they wanted Andy too as he is brilliant! Andy has spoken about the incompatibilities between the old 1500 stuff vs Nexxus, and it totally makes sense. It's not JUST software that is different, there is huge changes in the underlying hardware too. It's why Haltech has had soooo many changes in the last couple of years, in terms of Hardware, and Software, and why it has become so damn Amazing. Why do you think guys like Rob Dahm with his quad rotor, went from running Adaptronic's to running Haltechs? Andy. Pretty much, Haltech these days, is Adaptronic, but with more funds behind it, and more staff, and hence Andy's visions, and visions of other people that he helps shape their great visions, into amazing new products. All the new Nexxus gear, whole new software for it, new and better dashboards, the apps that will run on headunits and NOT be slow to respond! I understand people being burnt in the past, but if you're ragging on a company, about products and issues from many years ago, it's more a reflection on yourself, not looking or keeping up with new stuff. In which case, those people should be going back to PowerFC and Nistunes as the ECU's to rave on about...
    • Right, but I thought the problem has been for a while now that even if you know manifold pressure + throttle position you still have non-linearity and aliasing issues vs actual engine load? One way I can see things simplifying is going DBW, then all air going into the engine is represented by the throttle position. As opposed to a random bimetallic strip vaguely linked to engine temperature opening and closing a shutter or some random power steering air valve suddenly allowing a bunch of bypass air. But the same throttle position/RPM at ~atmospheric MAP in different gears is not guaranteed to be same engine load? Honestly, ITBs are of such dubious value IMO. I don't know why these things are hyped up so much. The main benefit as far as I can tell is you reduce the likelihood of cross-cylinder EGR scavenging with significant cam overlap at idle. I would absolutely run speed density and be done with it if not for this fairly esoteric control problem.
    • Hah dont worry, my adult brain has this conversation every single day. Dont waste your money, invest more of it into shares, pay down the mortgage. Then the bedtime insta doom scrolling begins and after being bombarded with gtr's my mind is set: im definitely getting one! I have the current model mx5 as the weekender, but i just miss my boost and literally like your username, the sututu's that come with it. I remember with my 2nd supra, as it had twins and vvti, they used to spool real early, like 1,500rpm so you could just be a spooly boy all day long. Some people say they get over it after a while, not me tho.
