02 maxima engine(vq30) convert to 300zx(vg30)
 

i have a 92 300zx with a bad motor and i have a 02 v6 3.0 maxima engine laying around (vq30) so read on a website http://z31.com/repairs/newengine.shtml how to convert a maxima engine into a 300zx engine but on the website the guy used a 88 maxima motor and i think he used a z31 300zx. but i got a new maxima motor and a z32 300zx so i was wondering if it will work the same and if i can convert it.

Just depends if the Maxima motor can be mounted frontward instead of sideways. You'll need to check the clearances, and see where the motor mounts will sit. You will also need the VQ engine harness and ecu, and both wiring harnesses to see which wires will need to be spliced / tapped.

Remember: ANYTHING IS POSSIBLE, IF YOU HAVE ENOUGH $$$. :D Be realistic tho... why not sell the VQ motor and buy a VG30DE motor??? That would save you A LOT of time and headaches.

It's been done in the S-Chassis before, he will need a Z33 Upper and Lower Oil Pan. + Custom motor mounts. and a Z33 Tranny.

Enjoy

if i do what it says on that website that i posted will it work?

no. totally different. '02 maxima engine is a VQ, the z has a VG. and a z31 and z32 are totally different cars. and the VG30s in a z31 and a z32 are very different engines.

ok thanks thread closed.

Well, sort of...the blocks are the same, but that's about it. You're mostly right. :)

thats what i need is the block. ill take a look at the engine cuz i got both of the engines at home but i dont know if the zx heads will bolt on to the vq block.

convert the Z32 to FWD! :)

yes, i am well aware of that, which is why i said "very different" rather than "completely different". i didn't feel the need to confuse matters, for reasons that are obvious below.

he was talking about the VG30E and the VG30DE. yes, they share the same basic block, but not much else. the VQ is a totally different block. it's also aluminum, whereas the VG blocks are iron. find a VG30DE. that is what you need.



and btw, '02 and up Maximas had the VQ35, not the VQ30.

if the blocks were the same on the VG-E and DE wouldnt people be swaping the heads all day long into their Z31? or at least having alot of easy swaping the DE into their Z31?

they are not 100% the same. just the same basic block design. and wtf is "having a lot of easy"?

unmmmmm... replace easy with people, and thats what i meant. and what you just said makes them different block designs. different oil/water pasages, mounting points... thats a different block design. they might be based on teh same concept being iron and a 3 litre V6.... but different blocks then. you guys lie

What he should do is sell both V6 engines and buy a RWD VQ35HR from a 2007 350Z. 306hp (265whp) :D

then he might as well cough up a few more G;s and get the VQ37HR from the 2008 GTR but that's just me thinking

oh, so true. Is that the same engine as the G37? 330hp?

i dont wont an engine swap i just thought that the vq30de fits into a 300zx.

Wouldn't swapping in a VQ30 be an engine swap? :paranoid:

G37 = N/A 330hp
GTR = TT 500BHP

i thought that the block from vq30de fits right into 300zx and uses same engine mounts.

nope. it does not. and if you have an '02 Maxima, it has a VQ35.

rebuilt or used 300 blocks arn't always that much. you could pick up a complete 50K Z32 engine for about $1000. maybe 2000 give or take for the whole job if you skimp a little.
