OK. As expected.




Arashi Performance is professional Japanese racing parts manufacturers.
Wait, what? So they make it in Japan and then ship it to China? Sounds strange.

Edit: It just says they are racing parts manufacturers. It doesn't actually say they manufacture it.

Arashi Performance is professional Japanese racing parts manufacturers.
So, Arashi Performance is ^them. Who is Arashi Dynamics?



Brand New and Complete CHRA balanced by Turbo Technics.
OK, now I'm really confused. So it is made by a company that can't balance it themselves? This is getting weird.

Description:
  • It's a upgraded Turbo for advanced drivers.
I don't qualify.

The bottom mounting turbo is a PITA in the NC so I need a direct replacement of a classic t25 mount . Gt2867-gt2871 etc won't work well they are a bit small for the 2.5 so I cannot justify the cost for a turbo that may not work ideally. A good solution is the gt3071 with the t25 mount.

If the Arashi are total junk obviously I have no need for them (I have spent thousands on my DIY setup) but I would like to hear a legit opinion from someone(If there is someone) who actually tried them, in terms of reliability mainly, because on paper the specs are fine.

It is easy to say yo bro this iz jank dood and offer semi knowledge across the board . The thread has been created for information not for flamming.
From my perspective they offer an interesting package in case you need a direct replacement turbo for weird setups like mine where is difficult to fit a proper turbo. You can't see the picture here . That's fine.
Of course there are great 600$ turbo choices if you make a turbo kit from scratch(precision, Borg Warner Holset)
That's all fair.

But nobody here is going to have hands on experience with that turbo, because it exhibits everything that we as a community avoid in turbos. Everything. We pay $179.99 shipped for cheap garbage turbos, or we buy used garretts, or new Garrets/Borgs.

^Like he said. Go full cheap Chinese and deal with it or go name brand.

Name brand $620 turbo that won't fit your manifold: BorgWarner Turbo S200SX-51 S251 (S200) PN: 177257

I missed the whole 2871 too small for a 2.5 thing amongst the jabber.

what part of a 2871 is too small? 2.5L is pretty much in the 2871 wheelhouse afaiac.

It will work. Now I am running a 2860 and the car is a beast but with full boost from 2000rpm lol . I need to go bigger. Stock rods are really struggling at these rpms
The gt30 turbine wheel suits better and will produce more at the same psi (15psi 400hp) The 28 wheel produce tons of baclpressure which is a step back . In a 1.8 or 2.0 is an interesting turbo.

Where are these numbers from? You telling us you make 15 psi at 2000 rpm? And 15 makes 400hp? Did I get that right?

No . The 3071-3076 range will get a 2.5 at 400hp with under 3.5k full boost.

Not sure if his comment was misunderstood, but he was saying that the 3071 will hit 400hp max and also hit full boost at about 3.5k. Not that it would hit 400hp at 3.5k.

I'm not sure why the 2871 is too small but... reasons.

I think a 2871 is fine for a 2.5L personally. The compressor easily flows enough for the engine and the turbine with a .86 hotside would do nicely. Turbine flow is pretty close to a 3071 .63 hotside.

I'll preface this with: I'm a team Garrett fanboy, so whatev.

Though to be fair, the "important parts" are probably made in Japan. They're real Mitsubishi CHRAs, so as long as you don't mind EVO IV era tech, they're probably plenty reliable. They'll just spool slower and aren't as efficient as fancy newfangled stuff. That's why old journal bearing BW/Precision/Garrett T3s are still cheap. Hell, look at GReddy/Tomei/HKS/etc older turbos, basically the same thing, and probably the same CHRA. It works, but it's not new or necessarily "good" depending on how you define that.
