I was wondering if I should upgrade the fuel pump to 5bar when upgrading to a bigger turbo,injectors etc? I already know that the fpr can be modified to 5bar but Should I include a 5bar fuel pump also?

From what I've learned the limiting factor with the stock fuel system is the size of the fuel lines. stock are -6. My solution will be to keep the stock fuel lines up to a custom fuel reservoir. Then run -8 lines through the fuel rail. I'll also be going larger fuel injectors to bring the idle fuel pressure down to be able to increase flow at WOT. Stock pump has handled 412hp.

Thanks for the help. So you recommend that I get 46 trim than the 57 on the t04e? What are the differences?

I'd go with around 50 in that dept., depending on your needs/hopes.

50 trim works really well, doesn't lag much at all.

Im looking for 375-390hp. I heard that 50 trim is a lot for stock rods. Is this true? Ill be running an FMIC and some other goodies.

Are you on stock rods? Any upgrades to the FPR? Thanks in advance

Stock rods and stock FPR for now. No problems yet. I plan on getting better rods and pistons.

I don't know if it's true or not. My rods have lasted about 4 months with moderate WOT driving. A co-worker has same set up and he has had no problems yet either. Better rods are in the near future though.

How long have you had the turbo in for?
