No more than 190rwkw with supporting modifications on a standard RB25 turbo on an RB20.

Read through this link below for some more info on turbo selection and power figures. Its a thread I put up about the same question and has taken off quiet well.

A lot of useless information and recommendations..

Short answer though. A HKS/GARRETT 2535 should get you to 240rwkw on an RB20 with supporting mods.

Hey i just wanted to know what turbo u would need for a rb20 in a r32 too make 220 - 240 rwkw?

HKS 2535, 2530, highflowed stock or better yet, highflowed rb25 turbo

and what power u can make outa a r33 std turbo on a rb20?

thanks

180-190 rwks

HKS 2535, 2530, highflowed stock or better yet, highflowed rb25 turbo

180-190 rwks

You'd be pushing a 2530 pretty hard in my opinion to get to 240rwkw as well as a RB25 high flow.

I don't think an RB20 high flow would get to 240rwkw?

220 and 240kw in an rb20 is a big difference.

you either stay below 220 or get a turbo that will make 240 easy

only thing in common between the numbers is that you will need all supporting mods to make the power safely

Yeah once your looking at over 220rwkw you have to consider bigger injectors as well as a Z32 AFM.

Decent size turbo, with a substantial amount of lag, over response.

After a lot of research and reading that thread in my first post on this thread, I have decided to stay under 220rwkw.

he did say between, so i was looking at both ends of the spectrum

Hi.

Please take the time to have a search around the forum.

There are a lot of threads on this, some already linked in this thread.

    • Oh, also, forgot to add these photos I believe.
    • Thought i'd update on this. I was able to get in contact with Craig Lieberman and later on Darryl Alison (owner of Kaizo Industries). Darryl was able to help me verify that my car was in fact one of theirs and is helping me find more info on mine !
    • 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.
