Standard Gtr Dump Pipes

[Guest Mashrock]

At what stage of flow/boost/power levels do the standard dumps start restricting flow? and causing problems?

i either have standard 32. or standard 34 dumps on my car.

34n1 turbos. (.42 front housing)

Anything bigger than stock turbos would definately benefit from a rear end flow upgrade

32 dumps should be cast

34 dumps are stainless from memory and are quiet reasonable design

pete

ps if the cast r32 i would upgrade running your 34n1 turbos but if they are 34 ss dumps you'll be fine

ok

so new boost controler and new dump pipes is definatley in order.

i see them as the only things restricting my flow and causing dramas.

mainly the dumps tho

trust split dump and front pipe will be on order next week

and hks evc 5 also is on its way now.

then more dyno and see how it goes then.

and then maybe a tune if my afr is still up the swanny

ha mash,

what is your intake system like as everyone concentrates on exhaust and forgets the same airflow that passes out the exhaust has to make it in and it isn't forced in it has to be drawn in under vacuvm through air filters and piping which is not all that good.

I have found running the 80mm afms (rb20/25 or z32) descreen and solid 3" hard piping very worth whiled and apexi pod filter(maybe the best pod on the macket for flow and cleanlyness) bolt straight up to the 80afms.

ps just another thing to consider

the intake is pretty good. except for the exposed pods. which will very soon have a nice alloy box made up for him i have the cardboard template sitting here ready to be made.

i'd say there isnt a great deal of restriction on the intake at all and a nice arc cooler to go with it all. hks pipe some where in there also.

and i havnt ordered them yet. still working out whats best for me.

changing your dumps requires removing ur turbos on GTRs

[rb26s13]

hks filters of death...

Changing the actual Dumps I cant comment on really but i was able to change both rear dump gaskets ....Turbos on.

I would of assumed this could be done !

hks filters of death...

meaning?

[GTR1993]

they only filter out small rocks, everything else gets sucked in.

hks pods

i second that you would be better served with a stocking stretched over the afm

Apexi pods are the shit ( i think best on the market)
