SR20DET - TURBO (GBC22-350, GT2560R OR GT2871R)

[timmy94]

Which turbo's are you guys running on your sr20det's? 

Im looking at the:

-GARRETT GT2871R (0,64AR) - $1350
-GARRETT GT2560R - $1050
-GARRETT GBC22-350 - $850

 

Im curious about the GBC22-350, anyone tried it? 

I currently have a built sr20det (top (cams, springs, solid lifters etc) and bottom(rods, pistions, coated bearings, headgasket and main/head studs)) but dont wanna run any crazy numbers, only safe numbers to get the car running again.
I also dont wanna break the gearbox since i will be running the standard gearbox (5speed).

Those aren't Garrett prices.

The GT2560R is quite literally the factory 91F00 S15 turbo. So size appropriately from there.

Get a GTX2860R Gen 2, it will do about 250~260kW and come all close to the side of 3000rpm on E85.

Looks great! Sounds great aswell.

 

maybe the gt2871 is the way to go then.

the GTX2860R is a bit pricey

GT2871 is so old, it's not 2003 anymore.

True. But does it matter if its a good turbo? 

gbc220-350 is a newer model, but dont know really mich about them. Tried to catch someone who runs it on a sr20

Like I said earlier, it's smaller than stock. You can just look at the numbers and compressor map to know this. Technically the turbine will flow more due to higher trim but the compressor flows less air at the same pressure ratios.

But is it a "good turbo", in comparison to actual, modern, good turbos? I mean, compressor and turbine aerodynamic design has moved on a LOT since then.

Subjective, I think it's a terrible turbo when compared to today's modern offerings.

Only thing "good" about it, is that it doses very well. You get a nice suuuuuututututut lol

I am now running a Aeroflow 5047 .64 rear (gtx gen2 2867 specs)

Previously ran a garret gtx gen2 2867 .82 rear

The .64 is the way to go as a lot more responsive.

I also run a stock 5 speed but its struggling and eating syncro's.
Car makes 220-270kw pending boost level.

Gtx2867 

If decide to go for more power will be ready to go for around 270-280kw and be super responsive. 

[timmy94]

Whats the minimum power you think you can run on that without promblems like surge etc

[timmy94]

The GTx2867 Will probably be alot more expensive. 

[GTSBoy]

Define expensive.

My idea of expensive is genuine G30 or EFR pricing. Like $4k. If you're talking ~<$2k, to align with your other OP prices, then.... none of that is "expensive".

Here's a Garrett GTX2867R Gen 1 I tuned

280kW on the dot.

Surge from what? Fuel?

If money is an issue look at other brands like mamba, pulsar, Aeroflow
