Thread: Opinions on this turbo

FYI, that turbo is nowhere close to the specs of a SC61.

If your goal is in the 350-400 max it would be okay I guess. Can't compare it to the SC61 in anyway!

Expanding on the above ^^

Compressor:

A 60-1 compressor wheel has an inducer of 59mm and an exducer of 76mm
A SC61 compressor wheel has an inducer of 61mm and an exducer of 82mm

Turbine:

The turbo you listed is a Stage III (T31) 76 trim wheel.
The SC61 is a Stage V (T350) 76 trim wheel.

Two lines each sounds simple, but makes a world of difference.

This is exactly the kind of post I wanted to see...! Thanks for the information.

No problem, keep it mind if you do go with the SC61, there are many variations as well. e.g. the turbine wheel specs above are for typical T3 flanges. There are also T4 flanged options and compressor housing options as well.

What will the rest of the setup consist of?

Basically, I want 86.5mm 8.5:1 forged pistons, some good rods with arp rod bolts, a good headgasket, ACL bearings, S4 cams, and so to build my DE for good boost. I need a T3 flanged turbo that is able to make like 420whp on good gas, and like 300-320whp for the street on lower boost and pump gas.

I'm wondering if that turbo would do the job. I already have the manifold and the Tial 38, and I'm ordering the internals, so now I need a turbo...

why not go with a little higher compression ratio? the turbos you are looking at my opinion are overly large for the power goal you are looking to make

Because fuel here is really crappy, I should use beer instead lol

For that I would just buy a Garrett 50 trim / Stage III turbo. I had one on my last B14, full boost by 4000rpm, 300whp on pump at 13psi, on race gas I have seen 380 - 440whp from myself and others. Also even with crappy gas (like I also have in Jamaica) 15psi will be fine, and that should get you about 320+ since you also have S4's.

Isn't that Garrett very close in specs to the master power one on the link?? With the .63 turbine. Sorry I'm a turbo noob.

BTW I have been in Jamaica, just loved it, I had a chance to visit Peter Moodie's shop and see some nice projects there.
