Default .64 trim 28RS will get you started... just make sure you get an adjustable wastegate

upgrade should be good for about 75whp if you use the right injectors. spool time is retained.

you can even get a compressor housing that appears the same as the T28

Default doesn't PES use 440cc injectors for DBW?

if that's the case, and he gets the right compressor inlet flange, he could reuse all the pES stuff and softare. That would be a pretty nice upgrade.

Default What is the part #? Because the RC web site shows all their injectors rated at 3 bar.

They sell a 440cc and 370cc injector both rated at 3bar. The 370cc injector is only 427cc at 4bar.

Default I used to run their 440's and their ratings are at 43lbs

There is a formula to see how much they flo at a higher pressure

Default Yes there is. Here is a web site that allows you to change the fuel pressure.
