Hello everyone. Im curious if theirs any problems with the 20v fuel system like running lean on certain cylinders? And if so should I convert the stock rail to dual feed feed or go after market top feed conversion? What size fuel lines are everyone running over 400hp, feed and return? What pumps and what injectors for 450whp to 500whp would you suggest??

The questions you are asking, and the advise that you require, are too
important to your build, to rely on answers from this or any other forum.
You need to talk to someone who actually builds high performance engines,
and has a proven track record of making the power you are targetting.

Can I suggest you take a look here... https://www.facebook.com/mrpltd
... and then get in touch with Barry (Bazza) Manon to discuss your goals
and how MRP could help you achieve them. Some old pics... MRP have gone
a lot further down the development track since then. Just put them in here
because everyone loves pics
