Ba Bf And Fg Turbocharger Specs

[pumpngo]

So the 3540 is comp 61.4-82, and the 3576 is comp 53-76 , or is my info on the 3540 slash 3582 wrong ?

sounds like a 2876 compressor wheel, 52.8-76.1

Bang on mate

The fg turbo is very unique

No other car I know has it

I have a 2015 fg turbo, im thinking of putting a gt35r core and .70 compressor housing onto my stock turbine housing, I know it will need a new higher psi actuator and a bracket to mount the actuator on the bigger comp housing and ported wastegate hole and bigger wastegate door. What sort of gain and extra lag can I expect??? thanks guys

Gain is dependant on how much boost you run when you get it tuned. Then again you can get good gains from your stock turbo. 

 

It'll be at full boost around the 3 grand mark or a bit earlier. 

 

You'll need a turbo side intake, battery relocation and charge pipe upgrade to use the larger comp housing as it has a 4 inch intake and a 2.5 inch outlet on the compressor. Something something tb elbow. 

 

You'll want an injector and fuel pump upgrade too as these will max out before a stock turbo is maxed, let alone a modded one.

 

You'll want a cat upgrade at a minimum but a turbo back exhaust is ideal. 

 

Imho it's a waste of money if you're paying to get it done unless you are getting a larger compressor wheel too, as the cost vs gain ratio, even with the slightly bigger turbo, isn't as good as paying the extra few hundred for a gtx or larger wheel. 

 

Without the aforementioned upgrades, you may as well keep the stock turbo and just get it tuned with injectors and fuel pump. 

 

Think about your end hp goal and what conditions the car will see and you should get some more specific advice from members. 

 

I heard that @JETURBO can juggle 3 of these cars in each hand with the lights out, while balancing on a fit ball. 

 

He'll look after ya

hey thanks a lot puff wagon, great advice. Lots to think about, might just get a pw stage1 cooler, and 15psi boost, injectors.

[Slowxr6t]

How much power can be made on stock injectors? And then with upgraded injectors how much power can be made on stock pump? Are stock fg injectors 440cc? What's the next logical step up in inj size, 1000cc to future proof? Do 1000s run nice like stock if tuned well? Or should I go smaller like 850cc or something?

[Slowxr6t]

Hey guys can someone possibly answer my questions in my previous post? I was talking to puffwagon, thanks

stock injectors for an fg xr6t max out at around 280ish rwkw.

stock pump runs out at about 300 (maybe a bit more, but most don't lean on it)

stock injectors are around 320cc/min, from memory.

next logical step up is FG F6 injectors, at around 42lb (400ish cc/min)

the one that all tuners like is the 1000cc bosch EV14 injectors, as they're easy to tune and have headroom left over for upgrades in the future. Yes, the 1000cc ones can run as nice as stock.

You can go with whatever your tuner prefers to tune and your budget allows and your power goals are.

Frig all. Jet answered this a few days ago but I can't remember what he said.

Fark knows. Just under 300rwkw.

Dunno.

It depends on your goals. 1000cc will take care of 99% of people I reckon.

Yes.

It depends on your goals and what your tuner can work with.

 

You might be better off to have a power figure in mind and then work out what parts you need afterward.
