t28 supporting mods.

[jprevette336]

i have quickly learned that the completely factory 1998 gst isnt factory as i thought or was told. i have come to find out that the balance shafts are deleted, its got a aftermarket cam (not sure lift or duration), and a big garrett t28. not to mention what ive done to it, GSC valve guides, new valves, 4 angle valve job, ARP head studs. i have the stock injectors but i feel that the cars running lean (plugs are white.) my question is do i need anything else?

550 or 650cc injectors, fuel pressure regulator and a 255hp fuel pump. Add in wide band, safc or link and a boost controller then you can run 23 psi all day

my future plans are evo 9 injectors, a wally 255, wideband, oil pressure gauge. what fuel pressure regulator do yall recommend? also what boost controller do you think is best?

I had an Aeromotive fpr. I've seen many people with the same setup. Also a Hallman mbc. Unless you were thinking maybe going aem Tru boost.
