Borg Warner turbo upgrade ??

I wouldn't recommend the 171702 without a tune, but with a tune it's pretty good. It is larger than the stock turbo. Larger means more lag. You want to cruise at 1500+ and when it's hot out it really wont start spooling until around 1350. It will keep your EGTs down and is capable of more max HP.

Downsides - more lag, less jake performance.

 

I have a 171702. And a rebel tune. Down low it is a bit laggy, but she does fine 1450 and up. Get your turbo from a reputable source. Spending less money on the upfront only to have to buy another and clean out the CAC after it pops isn't a good way to go.

 

Just another day at the office

 

tune ecm? can somebody explain me what does it mean ? rising the hp ?

 

that turbo you saw on ebay is 'made in china' borg warner product. today 95% oem turbo's are manufactured in china. just two day a go took out oem turbo from dd15 engine and the label was showing Holset HX55 made in china. Paccar's turbo is made in china too.

 

It involves adjusting the software to change fuel delivery , injection timing and boost/fuel delivery rates, in addition to pedal sensitivity adjustment.

Mostly it's used to achieve higher power and better fuel mileage.

 

thanks MB3MMX. on Detroit you can do that by using DDCT. and aftermath would be higher thermal load on engine components and fantastic high level of NOx and CO..)))

 

Ruthless Do you achieve that much boost on a regular basis? My 12.7 has a tune, a BW 171702 turbo, and a shimmed fuel pump. I would get nervous when the gauge went past 35 and would keep going if I kept my foot into it. The gauge only goes to 35 lbs. but the needle would start a second trip around.
