Since this forum has been around for about 8 years, a reply like this is not really funny coming from someone like yourself.

The poor dude needs some direction....

Enough of the bullshit...

Mate try and keep these turbos for another project and look into something more appropriate for your setup.... (or sell them)

The RB25 engine has been known to handle 300rwkw but its all in the tune and the parts being used.... Some people claim 450+ kw from a stock RB25.... somtimes i think about getting one and seeing just how far it can go just for kicks and giggles but been too busy these days...

Build it right and it should live at 280kw at wheels for a very long time....

BTW the mafia's comment made me LOL hard (but i am sure he meant duct tape)

good luck, shoot me a pm when you get sick of bein flamed for bein a newby...... even I was one of those here once apon a time....

Think your getting ahead of your self mate only the other day you where asking how to clean a afm. To op just read the rb25 dyno results

[soultz]

thanks for being supportive guys, i wont lie ive come from a holden background so i know nothing about jap imports whatsoever.....to be honest these t28s i just bought are for the holden, and the ones i have here i was going to put on i am now using 1 and putting it on the rb25....ill try and search for what i want from now on sargeRX8, bit i couldnt exactly find what i was looking for in plain wording so thats why i posted here.

How much power you after? Depending on the t28 size it may not be a good match for a rb25 it will also need to be t3 flanged.

[soultz]

basically im just wanting to replace the standard r33 one in there now, wind the boost up a little and ill be happy if i got 200rwkw. ive dot 3-4 supporting mods aswell so at the end of the day i want to get it tuned with all this stuff so im utilizing it correctly

It was in one thread about another problem, neat and tidy. I wasn't actually having a go at the guy, it just seemed the attitude he got from others wasn't helping. I don't know the answer to his second question and his first question isn't going to take a short response. It also isn't worded right, boost is not equal to power.

Had I not said he was being trolled, or you guys didn't jump in on this, he probably would have believed his turbos are capable of safely pushing 45psi.

Matter of the fact is, he was being trolled by other members, I merely warned him of it and why it was happening.

To attempt to answer his questions;

It all depends on what turbo you are running on your car. An example is if you were to run a GT3582r on your car and push 25psi. It may very well run nice and safe for a while and make some healthy power. If you got a bigger turbo, say a GT40, and ran 25psi off that turbo, chances are you will pop your engine. There is no direct figure. People often say don't set your self a PSI level, or a rwkw figure but I think setting a target rwkw figure can help you when searching for parts. If you want about 220 - 250rwkw with close to stock response you can get a highflow, injectors, ECU, exhaust, intercooler and AFM. Run about 14psi and she will be happy. My old highflow made 225rwkw on 13psi on a very conservative tune. With my setup, I should be pushing >300rwkw but the dyno shows otherwise. Its not all about boost, or one part in particular. Its all clock work. Every gear, every part, every component from the filter you run to the tip if your exhaust will affect the power you make.

See when I'm not on my phone I can give a better response.

As for your second question, those turbos will not handle 40psi safely. Free boost them, sure you might hit 40psi but....

As said. All about the tune

Lithiums RB25 had 300kw with 17/18psi for over 100,000km. Longer than the car had standard power. So its definitely doable.

They are pretty tough motors. Just be nice(ish) to them and have a safe tune.

With my GT-RS i ran it at 20psi on a stock motor making 262rwkw for about 50,000km before an oil issue caused me to spin a bearing.

Care and tune are king
