Default Mamba gt2554r

As i am searsching for a new turbo i came across a mamba gt2554r on ebay.
https://rover.ebay.com/rover/0/0/0?m...2F192419278459

Do any off you guys run this turbo or have any experience with the brand?
It all looks nice and the specs are also nice.
Would like to here some thoughts about this turbo.

Btw its for a stock 1.8 nb 1999

Cheers!

Just get a real Garrett one, ultimately the Garrett turbo isnt much more expensive and it will perform better.

Agreed.

I'm definitely pro-ebay in the right situation, but ball-bearing ebay turbos are not cheap enough over the real deal to justify IMO.

You could probably get a real garrett used for cheaper than that pretty easily.

Pricewise it would not make difference for me.
After import tax to The Netherlands it will be the same as a garrett.

I was just wondering about the quality and experiences from others.


At this moment i am running a chinacharger gt2860 from maxspeedingrods and i am not satisfied. Poor wastegate port and oil seals are already gone after 1-2000 kilometers off driving.
Thats the reason i was searching for a replacement.

For street driving and an occasional track day would you guys go with a 2554 or the 2560 on a stock engine?

And i am currently running 420cc rx8 injectors but i noticed during pulls in 3-4-5th the duty cycle is maxing out. Will a fuel pressure regulator prevent this or should i just go with larger injectors?

You can get a new Nissian GT2560 for between $700-$800 USD. Search on here for the part numbers. I would go that route over the Mamba one. Also I would go with a 2560 just to have a bit more headroom over the 2554.

A referenced fuel pressure regulator may help if you are running more than 16psi boost, but you probably just need bigger injectors.

You can get a proper Garrett from the UK for slightly less money:

Mazdaspeed Protege came with a GT2554R, they can be had pretty cheap since most wreckers don't realize it has a dual BB turbo.

You can get the GT2560R pretty cheap in the Netherlands, cheaper than then the GT2554r after import!

GT2560R for sure, one of the best turbos for under 300whp you can get.
