aridyne: how much power should  u put out with that high flow? and how much would that be costing you?

cheers...ben.

Well as it is in Sydney right now getting done I won't know until I get the car back, so I am looking at Friday/Sat Morning to find out.. I definately want the car back by Saturday noon as I am cruising down the coast for a bit of schoolies week site seeing :D and maybe a bit of freeway action .. :)

Will let u know what the cost and rwkw soon

i tossed up between the GT-RS and 2835proS and ended up going the 2835ProS

While they are rated only 20ps apart, (GTRS 400ps vs 2835Pro 420ps) When you see the two turbos side by side, the GTRS is notably smaller everywhere! This is probably in part due to new technology, but from the looks of them the GTRS might not go as well once you start flowing big amounts of air up the top of the rev range?

So far ive only seen GTRS results up to 1bar on a RB25, anyone got results at 1.2bar?

heres my 2835ProS next to a little CT12!:

What sort of power was the GTRS pushing at 1bar on the RB25?

That's the wastegate actuator hose. It provides the actuator pod with boost pressure which opens the wastegate....why would it not last long?

As with the hi-flow...and I speak from experience...The HKS is going to be more reliable whereas the hiflow is maxing out and will need to be rebuilt after 12 -18 months. This is just a simple fact. The hi-flows don't last as long unless you start fitting oil coolers and run low boost most of the time. I ran 17psi through my 32 hi-flow and got 220rwkw on standard injectors, standard ecu. The turbo is unreliable though at that pressure. Don't get me wrong though, you get a lot more bang for your buck...but it's worth the investment for the more reliable turbo...coz at the end of the day...the turbo will self destruct before you know it has done so and you won't be prepared for the bill.

Another option is to run a nitrous anti lag system and just put the biggest friggin turbo on it that you possibly can...yeah, do that.

Surely that statement is misleading. :confused:

Hi-flow means so many different things. If it was a plain 270deg bearing turbo then id tend to agree. If it is a plain bearing turbo with 360deg thrust bearing then id expect it to handle 1.2bar without any probs (your oil cooler call makes sense as oil quality / pressure / temp is imprtant). But if its a hi-flow using a ball bearing cartridge, why would a hi-flow be any less reliable then any off the shelf Garret/HKS/IHI (ie ball bearing) turbo?

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      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 😂

      Cas issue

      By GTSBoy · Posted

      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
