If anything, put a Pathfinder Manifold on it.

Full documentation there and a dyno graph.. though Ken's car is far from stock.

Well you could use a scoop to fit it..
Either that or have your current manifold "extrude honed" for more money than it would cost to put on the pathy manifold.

If you've looked at a TT manifold, you'd have known it wouldn't fit.

because thats the only practical manifold upgrade. the z32 manifold will not work. if your that worried about changing your manifold go with the pathfinder... if not port and polish the stock one

Because the pathfinder manifold is good for 30-40 hp above 5500 rpm!

if you look at the stock vg manifold its flat and sits low. then look at the pathfinder manifold... notice anything different? same thing goes for the TT manifold ... its a completely different set up than the z31 manifold. it confuses the hell out of me when people cant use common sense and see that certain things wont work. if your looking for power bore out the stock manifold... if you want looks and more flow go with the pathy manifold... if you want a TT manifold buy a TT. simple as that.

Here is an ebay link for a z32 manifold: here . Do you see anywhere on the z31 for two throttle bodies?
(If you could rig up using 2 throttle bodies for the manifold, then you shouldn't have to ask if it will fit.)

it uses a weber system so both the throttle bottis will open i just figured if i could fit it on and change some other stuff i would get more power than if i used the pathfinder manifold and it will also look sweet

no offense but you obviously dont know anything about your car. having 2 throttle bodies wont get you more HP. the z31 uses a single exhaust system, z32 uses a dual system ... the back pressure would be so great that it would probably blow your motor. btw is your car turbo or na? if its NA your wasting your time doing mods of that type.

I haven't tried it but Ive seen both motors and one the one you have is way different that the VG30DETT or DE(N/A) I just put a polished plenum is what its called not intake manifold. But i know what your talking about this pic



You really think you could put this on your engine? totally different design and why? to twin turbo? if you want to twin turbo your 80 whatever just do it sequentially(turbos in line)like the supras and skylines do, who also oh yeah have single exhaust systems....

sequnetial turbos are not in line turbos, its one turbo for bottom end, two for top end. Its proven not to really work that well.
