This is the smaller Garrett GT20 turbo, not much but it's down 5 HP from the other GT20 turbos in the family. Making it top out at around 220 HP. Recommended for the same engine size as the others 1400cc - 2000cc.
You can use this turbo also if you're looking at something in the 140 HP range. It have the same turbine as the other GT20 turbos so the only difference here is that it's a 48 trim on the compressor.

This GT20 turbo have the same oil inlet threads M10x1.0 and oil outlet M6x1.0 that the other GT20 turbos have. And like the rest it's also not watercooled.

Any ideas if this will fit a 85 AS TX5 2.0l turbo?
ReplyDeleteHello, if it's more power you are looking for then yes this GT20 turbo would work. However if you want a faster spooling turbo over the stock turbo but not looking for more power then you could go with some of the GT15 size turbos instead.
ReplyDeletecan i use gt20 turbo on my g13b engine 1.3l petrol engine
ReplyDeleteHello som cd, for your Suzuki engine you could use the GT20 turbo and it would give you around 200hp with 1 bar / 15 psi boost. However for a faster spooling turbo you should go with the GT1548 turbo instead, it would make around 180hp at the same boost pressure with a good tune and setup.
ReplyDeleteCan you use a turbo of a petrol engine to a diesel engine? If not, why?
ReplyDeleteHello Tom, good question. Yes you can use a turbo from a petrol engine on a Diesel engine. However because Diesel engines need more air than petrol engines (around twice as much) the turbo also needs to be around twice the size.
ReplyDeleteSo as a rule of thumb, you would need to find a Petrol engine turbo capable of supporting around 200hp to be able to make around 100hp on a Diesel engine.
This is not always the case for new Diesel engines because over the years they have become more efficient. And if you can burn Diesel more efficient you also need less air and can make the same power with a smaller turbocharger. But it's not a big difference we are only talking around 10% here.
But if you can make a new engine 10% more efficient, then that same 200hp Diesel engine is going to make 220hp instead with the same turbo size. Or if you look at it from the other way around you would only need a 180hp petrol engine turbocharger to make the same 100hp on a modern Diesel engine.
Now if you are looking for a turbo to make 200hp on a Diesel engine then this GT2052 is simply not big enough. To be able to make close to 200hp on a modern Diesel engine you need to look at a bigger turbo like the Garrett GT2860r.
Hi, in fiat engine 1.6 105 hp with garret 1446sz (31/46 compressor and 32/39 turbine) I am thinking to put a borg warner of the 2.0 multijet engine with 135hp with P/N 54399880093 (kp39) witch has 34,1/46 compressor and 32/37.5 turbine.
ReplyDeleteMy question is... The car with stock turbo can makes about 140hp without dpf. How much horsepower i can make with this kp39 and what pressure is safe for the turbo? Also why the kp39 has smaller turbine wheel? Less blades?
Hello Tom, there are no compressor maps found for the modern Borg Warner KP39 turbo. There is an older KP39 turbo but it's different to the modern KP39. It's also said the KP39 is a smaller K03 turbo.
ReplyDeleteSo I can't really say for sure what a max safe pressure is but around 1.5 bar / 22 psi should be ok to run on a daily basis. The turbine geometry and size is different on the KP39 turbo, I think Borg Warner was trying to make a more efficient low pressure turbo.
That said, looking at the size of the turbo you could probably make around 20-30hp more with the KP39 turbo.
