Lots of questions but that is because I am very curious as well, as I am looking at alternatives to possibly replace my dom3....
I'm sure a gen 2 makes more power. But it's also $500 more. My car isn't really built to handle a Gen 2 right now. I'm on stock heads, and a non-closed block. Plus, I only have 1300cc injectors. I'm guessing the XR would get me to 500whp on my dyno and elevation, and I can get a discount on it through a friend. Plus, I really like FP stuff now. So I don't mind supporting the business.

Just saw a Gen 1 3076 do 572WHP, but with 272 cams.

I wouldn't mind stock location if it wasn't such a major PITA the work on :-/

What is the best anyone has seen a Red get too? Like 550whp?

I'd like to go rotated, but I'm really not looking forward to all the extra money on exhaust stuff. I'll never need more power than what I can get out of a stock location setup anyway because more than that is not good for the streets, track, or canyon runs. Just highway pulls, and I do my best to avoid that.

its a big ass turbo for stock location. and altitude doesn't help turbo spool. but i may be a little jaded. my current td06sl2 doesn't make 15 psi til ~4300 RPMs and im on E85

the turbine wheel is slightly smaller than mine.

the compressor wheel is about the same. the benefit of 3" inlet might help.

Nice, thats more in line with my goals. I will be happy to end up in the 500 whp range with torque around the same number... Currently my car's torque numbers are a little low for my liking (under 400 on IAG's dyno), which is one of the primary reasons I am considering a turbo swap. It sounds like the difference between a 3576 and 3076 is not that substantial from a spool perspective, but the 3576 provides huge margin for increasing power later... but I think it will probably be too big for my current setup, so need to figure it out. I started reading up on how to read compressor maps and calculating proper sizing, etc. Once I know this better, will apply to the two turbos and see where they map out. Also, I am not necessarily set on only one of those two options and if FP has a good cost effective alternative I will definitely be interested.

Regarding stock vs rotated location... I feel that once the car performs to my liking I will not continue to modify more, and if that level can be achieved with stock location, It will be my preference.

It's really hard to justify going rotated when a stock location XR Black 82 HTZ can make 600 whp. Interested in seeing what a stock location GTX3576 Gen 2 will make too.

I was considering a BCP x500+ turbo at one point seems that will get you to 500 whp quite easily.

I'm at that point where I've done everything I can to do my car. Next step is essentially a $20k commitment to get a built block.

I mean, the turbo isn't that big. The housing and everything are basically the same size at the FP Green. XR Red and Red are different sizes. That of the XR being smaller with a more efficient wheel and ball bearing not journal bearing. So I actually think this would be more ideal for altitude than the Red.

My FP Green is hitting 24psi by 4200rpm, and I'm guessing this XR would make more boost at the same rpm range.
