S15turbo+greddy intake manifold ???

[2.240s]

s13 redtop s15 turbo,fmic,tomei expreme mani,boost cont 9 psi, 3in exhaust /testpipe.Going for 555 injectors/enthalpy rom tune 15psi 91 octane and a greddy intake manifold. Will the greddy mani hurt my performance with this set up ?? will i lose a bunch off the line??

i dont know much on this subject...but in the grand scheme of things the greddy mani should only help not hinder.

dude u almost have the same setup as i got, the only thing is its not on the car : ( but i have the s15 turbo, 740cc injectors( i dont know if i over did it on the size), greddy fmic, koyo radiator,and i was gonna get the tomei exhaust mani ( i see it on ebay with the heat wrap for about 500 bucks) full custom exhaust 3 " but to get to my point is i bought a seperate ecu so when i send mine to jwt or enthalopy i can still drive it, what made u go with enthalopy cause i need to get mine tuned and i dont know which one to go with. sorry to thread jack

They say you gain a few horse with the intake manifold but loose a little torque. I like mine and could definately feel the diference at WOT. Of course I have gt28rs too. The only reason I really got the mani though was to make it easier to change my oil filter... haha

I dont know why enthalpy, quick turn around,I dont want to deal with tuning a safc II. I am happy with the tomei manifold, it helped turbo spool and feels a lot quicker now. i am just afraid the gredd mani will kill it.
