Just checking to see if anyone has purchased and installed the Tomei Arms Turbo MX-8265 and was able to dyno. I just purchased this on a black Friday sale and I wont be able to install and test until it gets a little warmer here. I saw a 240 install this turbo on YouTube, but no information on his numbers yet. I can update once installed, but this turbo is so new you cannot even register it for warranty on the Tomei website....

I also purchased the Tomei turbo elbow to assist with back pressure. Again not installed.

Hello Joe,

I'm really keen to know aswell since HKS GT-RS kit for RB25 have been discontinued.

I was seriously considering picking up the Tomei Arms due to it being one of the only bolt on turbo kits still available from a Japanese tuning house but read not so promising feedback on the units.

Good link, alot of product info. I don't really understand turbo specs. Can someone help interpret the turbine, compressor wheel figures and trim? What is it comparable with Garret catalogue? Their naming convention seems more straight forward.

Billet compressor wheels are a good feature but ball bearings are generally more favourable than journals.

Hope it turns out to be a ripper turbo though, please tell us how it goes.

Going to be honest, they're pretty poor performing turbos.

If you look carefully at them, they're just rebadged turbos.

Hey, just checking to see if you have seen them in action, or have any dyno results to show their poor performance. Are they rebadged stock turbos? I know a number of people have hi-flowed their turbos and they are happy with them, so wondering about that as well. 

Just checking to see where you have got this information from, it would be helpful for me.

    • 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 😂
    • 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
