i heard from a friend that our 4th gen maximas(vq30 engine) have the same block head as the 300z. is this true, if so can any of you guys support your answer.thanks

 

Nope, it's a totally different engine. Geometries are totally different...the VQ30DE Maxima motor has a wider bore and shorter stroke than the VG30DE 300Z motor. The engines are pretty similar in a lot of regards (4 valves/cylinder, 3.0L, etc), but no, they're totally different.

 

i did a full swap on my maxima so it has a 300z engine in it

 

nice bump. pix or ban!

 

^^^^

 

Which 300ZX engine? That would help out as to whether you should post pics or not. If it is TT engine, then hells yes! That would be an AWESOME swap.

 

The guy has a 92, probably a VG30E, if so he probably is talking about the 84-89 300ZX, or "Z31." Obviously our maximas engines (VQ30DE) is different from 90-96 300ZX engines (VG30DE, or VG30DETT).

 

That's awesome...except you're in the wrong section. Go to the third gen section if you want to gloat about your VG swap.

VG30DETT fail. Anyway, it won't fit in a J30, most likely wouldn't fit in an A32 either (though I can't imagine a single reason anyone would want to swap the VQ out for one).

 

Oh, I didn't say it was a better engine. I just thought that it would be an interesting swap to see. I actually got on this site because I was interested in the VQ30. I am looking to swap one into a S13 coupe over the summer and was looking for more information (I haven't really searched for anything yet though) but I am extremely interested in the VQ30 and what it can do. I just like to see different engines in diferent cars. It makes me smile.

 

pics please or no care

 

how

 

I would disagree on the fail comment. It is a very stout engine with good horsepower potential from the factory. However, it is big, heavy, hard to work on and expensive to get parts for. It is EXTREMELY hard to work on them in the Z32, let alone any other car it gets swapped into.

 

umm if you want to swap that into you S13 you do know what kind of tranny you need right? it's not an easy swap like an SR i was thinking about doing this to my S14 kouki but there is just so much you have to do to swap it in.. oh i would take a VQ over any VG

 

It gets both a fail and a win in the engineering, especially when in the Z32. Win for Nissan being able to design everything to fit in a relatively tight space, fail for it being the biggest PITA to work on.

But, I still say fail. There's so many cons about the engine that IMO there aren't enough pro's to balance it out.

 

like?

 

I have been doing some reading up on it. I plan to run a Z33 6 speed mated up to it. I know that it is going to be difficult, but I'm not scared of some fab work!! From what I have found on Zilvia, it uses a similar block as the VQ35 (as long as it is the aluminum block) and will use the Z33 mounts as well. Fab work really isn't my specialty though (I think a blind 4 year old can weld cleaner than I can) but wiring is where I really shine.

I still have a lot of research to do, but I am not giving up on this one. I am a really big fan of the engine itself. Once I get the engine (4th gen Max's seem to be plentiful at the junkyard by my house), give it a good OEM rebuild then I will take it to my buddy's shop and really get dirty!

 

Basically. There are some others, but that pretty much sums it up.

 

Andrew91SE is back!!!!

Pics or

 

very nice.. yea i was just thinking the transmition would be the most expensive part of the swap.. but that would be an amazing swap.. good luck and keep us posted

 

 

I am here...
