No power gain at all.....
You will get nothing because they are the same specs. Why don't you go get a baseline dyno done now so you can dyno your own mods?

Didn't Bryan put n/a z cams in his max when he had it and gained some power?

The cams are the same duration and lift, swaping Z cams would mean regrinding them to for lower lift so you don't get piston to valve contact. The reason the VG30DE has more power is its compression and intake manifold. That engine has a huge dual plenum setup. Even though the intake runners in the intake manifold gaskets are the same, the VG30DE has a higher volume capacity. If one was to swap in a Z32 NA ecu, you'd probably gain very little power but you would have a 7000rpm rev limiter vs 6600rpm stock.

Nismo I thought they were a little different? How come the 300zx n/a has 220 hp then? Is it just the engine management, intake and exhaust?

if you did swap ECUs, would the higher rev limiter be worth it?

ok so from what you guys are saying this mod doesn't sound like it worth the money, but how would it stack up when you add a jwt ecu along with the usual mods like CAI,y-pipe,2.5 exhaust,bored throttle body and port matched headers and udp.After all of this is done shouldn't the max have a crazy top end especially with the rmp hike.well please excuse me for asking so many questions because i'm just hp trippen.

Nope
Its not possible at all, the manifolds are way too big and wide. Not to mention you can get better power from cams, I'm not sure but I think the older plenum on the Z31's made the same power with less torque. The high rev limit probably isn't worth it right now, its better to just get a JWT ECU.

is it possible to swap the intake manifolds from the VG30DE to the VG30E? would you gain enough power to make it cost effective?
if you did swap ECUs, would the higher rev limiter be worth it?
thanks
