What turbo for 300bhp redbock

[OttoB]

Mitsu16T-6 (straight)
A-cam
B230F completely stock, new rings
RE85
1,4 bar boost
295 hp
330 squirrel furs per quarter backyard torq somewhere below 2500 rpm

Gasoline was around 260 HP and lower boost (1,1 bar) because of knock.

Lowering the CR to 9:1 would be a good move when using gasoline.

I like this a lot as a simple daily driver recipe.

This is a really great deal, will do 300whp++ and spool fast. https://turboneticsinc.com/store/index.php?route=product/product&path=35_42&product_id=780

I would put a ipd turbo cam in it. A bit more mild then what you have. What are you doing for tuning?

 

[Steerfromdarear]

I'd like to change to turbo what these numbers look like
Compressor:
Trim: 48.1
A/R: 0.5
Inducer: 52.7
Exducer: 76
----------------------
Turbine:
Trim: 74.2
A/R: 0.57
Inducer: 64.8
Exducer: 55.8

I think you should consider the above advice before buying more turbos.
Starting with the poor cam choice, and answer how you are tuning this.
Ignoring good advice is a great way to not get any more of it.

I've put a bunch of these on a bunch of cars. It's a nice kit, it installs like a factory turbo, they work and the last. They have bigger ones too. Use this with a 90+ manifold and stop overthinking the turbo choice. Move on to all the other things that prevent these things from making power.

Learning is good, not faulting you for that. Turbo selection can be complicated, and if you don't know about AR ratios, compressor maps, and all the things that go into selecting a turbo, go with one of the many selections people have pointed out above. You aren't going to come up with better ideas on your own.
Maybe learn why these people think those selections are good.
