Just little things like a turbo beanie a turbosmart dual port plumb back BOV hks adjustable cam gears and fine tuning timing belt a bosch z32 afm gotta bmc direct air intake filter kit cos I reckon my arc airbox is drinkin hot engine bay air 550cc sard injectors a malpassi FPR Many metres of header wrap and the wider exhaust wrap. I think thats everything lol

Could you please post a pic of the BMC air intake?

ive tried putting pics up here countless times and no matter how much i compress the picture its too big!

sorry mate ill try again but im sure ill get the same result

External and AEM EMS controls the boost. The saga for him to get to this point.gtx3076

After trawling through a pile of pages here is the page which shows the result from the GTX3076 on pump and race fuel (the posted dyno previously was race fuel).

The GTX3076 looks like an expensive GT3040.

The GTX3071 on paper should flow enough to cover a GT3076 if the turbine can pass enough exhaust which is the question mark with a non-garrett turbine housing.

Yeah i cant wait to see the results i know im still gunna be happy either way because my baby 203kw feels good on the street! so surely the 250kw at the worst is gunna feel pretty darn good and if i dont get the power ill run e85 anyways as im still toying with the idea cos im liking the smell and the lack of black stuff all over the back of my white car and if i ever get put over the pits im sure my car will pass an emissions test!

Ive been considering selling my 550cc sards im wondering what are the biggest injectors i can put in my standard fuel rail are? for

Thanks wolverine yeah i have a servo around the corner that sells it and apparently all the cops around here in the Hawkesbury are running on it so its a reliable source im lead to believe so might try flogging my 550cc sards

740's might be better for E85 but unless you have some easy way to switch tunes E85 is a tough one to use day to day unless you have a servo around the corner.

Jez will get you a good result so all the best from here.

how much for the sards :)

You are actually very close on airflow with the GTX3076R and a 56T GT3040R like you have .

It's also interesting to compare the compressor maps of the GTX3071R and the original GT3076R 56T , the 71X has very slightly higher ie 1% adiabatic efficiency but the original 76Rs center island is fractionaly wider and a tad to the left of the Xs . I compared these along the 2 bar line , remember this means absolute pressure so 2 bar here is 1 bar above sea level air pressure , because 15 pounds is not an unrealistic number for starters .

Sorry to be a grinch but these GTX compressors don't look that good on paper to me especially in the T04E and T04S compressor housings . I think the 52 or 56 trim GT37 (76.2mm) compressor is comparable to the GTX71 and as Andrew said its debatable if the GT30 compressor is adequate to drive the GTX76 compressor wheel given it looks to flow similar numbers to the 82mm 56T GT40 compressor wheel . I wouldn't even bother to look at a GTX3582R because the T04S compressor housing is a bit limiting even for the 82mm GT40 compressor wheels air flow capability .

The high points of the Xs seem to be high pressure ratio (boost) efficiency but over a relatively narrow range , and also they're supposed to be quieter in port shrouded compressor housings .

I suspect that they would work better in larger comp housings and with larger turbines in diesel applications .

A .

^ That is pretty much what I said when I first read over the GTX series compressor maps, the only one I held any hope for was the GTX3071R on the premise that it should be able to perform similar to the GT3076R in most cases with a little more transient response from less inertia, though as it turns out from testimonies from people who have drive GT and GTX equivalents, the response actually does reduce a bit meaning even that may be a bit of a waste of time.

On the flip side, I have heard of some really impressive power results from GTX3582Rs when more exotic fuels than run of the mill gasoline are used - so if one was going to head down that path, they could show some worth there. I've still not seen any results from a GTX30-series turbo under real duress, but maybe they could still have surprises up their sleeves.

Think i should mention that boostn imports has a great price for a kit that bolts up to the standard dump pipe and factory headers with sonic braided lines $2638 delivered to sydney!!!! SPECIAL!!!!!!!!!

An aquatintence of mine got that kit and was less than impressed with it, was missing lots of bits.

Hmmmmmmm i hope my kit aint like that :rant:

was he pissed bout just the lack of parts to install it?

Or its performance once bolted in?

    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
