Try and setup everything you'd like to do one time. It's much less expencive that way. If your realy wanting a larger turbo and thinking "I'll upgrade later" you will but you also will be spending twice as much money.
Research and buy eveything ONE time.
A TA49 turbo will support 550hp flows 800cfm and has a minimal stall difference than the stock GN turbo.
I'd run that turbo with 36-42lb/hr injectors
You'll have to use a chip to upgrade to a larger injector
Or the "pocket romulator" I mentiond above and Tuner Cat.
Adjustable Fuel pressure regulator
225-340lb/hr fuel pump (in tank)
Don't forget to make a oil return in your oil pan before re-installing it!!!!
Or a place on the block (if avlb)
People made fun of my Maxima untill they saw it spanking a Ford Lightning truck at US 41 last summer (my 13.40 pass
)
They don't laugh anymore
