Just wondering, how much boost can you push (generally) on a dsm before you need to upgrade your fuel pump? And secondly how much boost can the 2nd gen turbo make(T28?)

 

The t28 can push between 14-15 psi. You do not need a bigger fuel pump on the stock turbo, but as soon as you upgrade it wouldnt hurt to get a new fuel pump. But you will also need a wideband gauge and safc2 to tune it with.

 

When you want to go past 17 you need a walbro. If you only plan on running like 23ish on a 16g, then you will only need a 190lph, if you want to run more, and on a bigger turbo,then you will need a 255lph with a fuel pressure regulator.

 

alright awesome, how safe is it to turn the stock turbo up to ballpark 14psi?

 

yea you'll be absolutely fine at 14

 

The safety limit for that turbo i would say is at 19, although 17-19, you really arent going to experiance a lot of gains, but its still nice to have. On stock fuel, 16psi is where you should be at.

 

am i the only one that caught this. Its a T25. I know Boostnightranger was asking...but bestwiseguy reiterated it .

 

Oh **** my bad i didnt even notice it. Thanks for pointing that out TE.

 

ya i couldnt remember if it was the T25 or the T28, if its the T25 then isnt the T28 the newer version of that turbo?

 

It is just a bigger version of the t25.
