Check put these turbos...

I really appreciate the recommendation! That痴 a great price for twin ball bearing turbos. I知 99.9% sure I知 going with those. I知 going to reach out and see if they offer them in a V-Band instead of a T4 without the cost doubling.

No problem, just double check on what you're getting before you buy.

LMK how you make out ..

What do you think about these? Same vendor. I noticed in the description that it has a flank milled wheel vs point milled. Not sure how big of a deal that is? I sent the vendor a message asking if they have them in a mirrored configuration

I assume the turbine housing would be too large with these?

A mirrored GTX3584RS billet point milled twins configuration with 1.01 V-band

The 101 would spool slower. I don't know how much slower. But I'm sure it would be ok. You would have more potential top end hoof. Either one will be a lot of power. I personally would stick with the smaller A/R.

It could give a better finish surface, but I wouldn't think that it would be anything that would be noticeable performance wise imo.

What's making you look at these over what I sent you?

Only looking at these for the simplicity of a v-band vs a T4 mount. If I can get the guy to package the turbos you suggested with a v-band exhaust housing, I’m buying them. If he can’t I’ll probably just buy the T4 version.

Oh, I see. I wasn't following what you meant. Yeah, having the v-band there gives you a lot of universal options .. I've never had one set up like that before. Would be a lot easier to take it off and on that's for sure .. Hopefully he can get you that option ..

I was actually just about to. Are you trying to stop me or encourage me?

While looking I just saw these GTX3582rs turbos. From what I can tell they are very similar to the GTX3584rs but are a little bit smaller and have a 10 blade turbine instead of a 9 blade. Not sure what you think of the different turbine? Probably splitting hairs at this point since they are pretty close in size.

Opinion?
