has the potential to yes but it's all in the tune man

first , 0.40 over ?? is there deep scoring ?


IMO a mkiv TT pump > the W255. quieter , and more reliable


you won't need to upgrade the fuel rail .



lastly, i don't see anything about BHG prevention








get a nice clutch, some stickys for the rear , and let her rip

.040 over, because i already have the pistons from my previous motor.

and i forgot to mention, i have arp studs and am getting either a cometic or hks mhg.

could you elaborate on the mk4 fuel pump? does it flow the same?

 

[topguncam3888]

MKIV fuel pump flows more.

What is required to use the mk4 pump? I would assume just the clip with some wire left for splicing?

You got plenty of turbo and fuel, so 500rwhp won't be a problem. And neither will the Walbro pump, that's what I've been running the last 6 years.

 

[topguncam3888]

Walbro would do fine really. There are different types of Walbro pumps so choose wisely. Some are better than others.
