how would the .70 rear housing affect the turbo???

only running 17 psi. on the car at the moment. no cams either.

what sorta power will a gt 30 max at on a 26???

someone said 320kw.. is this right???

Bring it on sooner, choke power output - either way it doesnt matter as it wont improve it massively.

For anything less than 400-440rwkw, you do not need a T04Z.

A 3076 on PULP will pretty much be maxed around 300rwkw give/take.

IMHO

3076 = 300~

3540 = 340~

GCG have a range of exhaust housings available so that you will be able to bolt a 35R on without much trouble. You will need to alter your oil and water lines, your intake and hotside pipe and your dump.

Expect a good gain in performance at the same boost level.

Yeah its built,

No cams yet, was told that cams will increase boost response.

might be the cheapest option.

still trying to figure out how much differance a .70 housing will give me on the t04z. might be enough for what im after, with cams of course.

should i expect a 500 rpm gain or what...?

any idea????

Mate, reread everything posted in this thread, using a T04Z for 300kw is a waste of time, irrespective of whichever rear housing you use.

It's like paying $50 for 6 big mac meals, at the end of the day, your only eating 1 and the rest will just make you fat and slow !

Hahah good analogy.

Nice way of putting it.

Turbo came with the car so i didnt choose it.

but i have another manifold that is t3, so t67 is a possibility.

still doesnt answer my question,

what will a .70 rear housing give me in the way of response.

Built engine yet only 300rwkw with a T04Z on 17psi?? Something sounds wrong?

The advice from this forum will be dont worry about mismatched turbos by changing housings just get an appropriately sized turbo

The question to ask yourself is would the same response be ok if it made a heap of power? If yes then turn it up, if no then yeah change the turbo. Cam gear will get some more response but not huge amounts.

If you have a T04Z all installed and working well then I think there has to be big gain to changing things. After all most of these cars are to have some fun we are not racing for pink slips... well at least im not hahaha

    • 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.
