So i did the 5 spd swap months ago and just now got around to swapping the Variable intake. I go to buy some manifold plenum gaskets and in the book they only have these engines

VG30DE SOHC
VG30DE DOHC
VG30DETT

My question, did they even make a DOHC VG? I assume it was a misprint and went with that, but i find it odd because I went to Advanced Auto parts and CarQuest auto parts and neither had a listing for the VE30DE for an intake manifold plenum gasket. Either way they had to order it and I wont have it till saturday, but it would be comforting to know rather or not I ordered the right stuff.

 

SOHC VG30 is in the maxima 89-91 gxe/se and 92-94 GXE's
DOHC VG30DE is in the 300zx 90 - 96 and 93 - 97 infiniti J30
(yes there is a DOHC VG)
VG30DETT is also DOHC - 90 -96 300zx twin turbo

Make sure you get the gaskets for a VE30DE, the gaskets are different than the ones that u've mentioned.

 

Fel pro doesn't list any gaskets for the VE motor
The VGDE motors are total different gasketwise.
Chances are they order the wrong gasket.
I do happen to have a plenum gasket for sale for the VE if you're interested.
I bought it and didn't need it.

 

I would have them check the part numbers on the "VG30DE" maxima gasket against the Z32 gasket for the 300ZX.

I've noticed several times that the "VG30DE Maxima" gasket part numbers are different than the true VG30DE numbers.

 

Beck Arnley Plenum Gasket PN# BA-0374812 $6.49
Go to Napa and give them that part number, or ask Brian to order that part number.

It is the gasket between the upper and lower intake manifold. You do not need to swap lower intake manifolds because they are identical. You still need a throttle body gasket, but then again I've reused mine 4 times already and haven't had a problem, lol.

 

Awsome, thanx for the quick response. Internetautomar, If you have 2 gaskets id prob take you up on it....as I have 2 cars. Mrgone, thanx for the part # and info, was wondering if i had to swap the lower manifold or not, but I guess you cleared that up.
thanx

 

[shameless plug] well i see you're looking to replace your TB and IM gaskets..funny, i make them..they're a bit more costly than the stockers, but they block a ton of heat and space the runners a bit...shoot me an IM sometime and i'll give you some details..you're local enough to me where i could meet up with you sometime and save ya some money on shipping [/shameless plug]
