Whats Got Better Flow

[spirosky33]

hks cast low mount manifold or a top mount drift/6boost manifold

just looking for opinions on the best set up flow etc

mods already done rb25

arias pistons 20 thou oversized

eagle rods

knife edged crank and balanced crank

9:1 comp

head extensivly ported, cams of custom grind,solid lifter conversion etc

garrett gt3540 with 64 housing 44mm tile wastgate

lots of other custom mods that i dont really want to get into

i have 6boost manifold and that is a 100% top quality designed manifold... there was a test done somewhere i read on a fairly modded sr20 it made a shitload more power on the same boost level, over the previous one they had on

ben...

thanks for the reply ben

ive heard good things about the 6boost manifolds have you got a number that i can contact them on?

[R31Nismoid]

stock would be fine, the small rear housing is going to be the limiting factor for you, not the manifold.

Other than that, any manifold will do you.

[spirosky33]

not much in the engine bay is stock .......id like to keep it that way

the stock item probably will do..but so would stock internals etc each to there own i guess

just trying to get the most eficiancy out of every part and regarding the 3540 its been proven to me with a machined slotted front housing its not really a limiting factor at all[from garrett eng] yes itll limit the flow to maybee 650hp instead of a true 700 roller but what i lose top end i will make up in quicker spool up/mid range power
