Opinions on Nissan VQ motors

[Angus]

I just wanted to see what people's opinions were on nissans 3.5 and more importantly, the 3.7 v6's in the g37 and 370z's.
Take well to simple mods? Reliable? Know issues?

expensive to mod.

the vq is a stout motor tho and i never had a problem with mine aside from one coil pack dying on me. simple fix.

There is a single turbo kit in the works for the 350 that actually uses the stock exhaust manifolds. Around 500+hp if IIRC

Expensive to mod, but amazing cars to drive.

They sound great. I have several friends with them and they all have had great experiences.

I've heard a few early 3.5's with some bad ticking sounds (dunno if it was injectors or lifters or timing chain, but a quick google search shows a good number of hits ). Otherwise yea, fairly stout, kinda expensive to mod.

they sound like sex with stock exhaust

 

[radioguy6]

The VQ series are great engines. Strong, reliable, and sound sexy at WOT, even back to the VQ30DE. My G35 has 83K and runs great. People have easily gone 250-300K miles with general maintenance. ALOT of 4th gen maximas have over 300K on the original engine.

Good aftermarket, but as mentioned expensive. The VQ is tuned well from the factory, with decent factory intakes and exhausts. For the amount of money, some mods arent worth it but definitely can squeeze power out of a N/A VQ35/37.

 

[Mook]

very little gains for most of the NA mods. 5-10 for exhaust. another 10 MAYBE for headers....a few for the intake. i think the best bang for the buck is the plenum spacer, imo.

headers are NOT worth it for the invested time vs power given.

 

[radioguy6]

the factory intake on the G35/Z is designed very well. Aftermarket intakes do barely anything. Plenum spacer is the best N/A mod for the money.

I haven't heard any complaints on them. I know one of the guys on Chicago Z has a 370z with a supercharger kit on it. A couple of other guys have just basic catbacks/intakes/plenum spacers etc.

I don't think they are that expensive to mod but maybe I am just used to it.

I know the motoiq guys just did an article about the AEM intake kit which got like 15hp and 10tq gain across the board.

I still love the way the 3.5 and 3.7 VQ's sound. Wish my 3.0 VQ would sound like that.

Two thumbs up. Those engines are really reliable. A good, cheap luxury alternative that's reliable and fun to drive. The G essentially rides on a modified Z platform and many suspension/wheel options are interchangeable among the various years.

 

[Mook]

some people hated my exhaust but i loved it.

 

[radioguy6]

if I went with an aftermarket exhaust it would definitely be a Nismo catback w/ a Y pipe off a VQ35HR G/Z.

 

[willizm]

I barely made over 300whp with my g37 6mt with a custom tune, HFC's, exhaust and CAI. They are shit for modding unless you go fi. It's a fun car, but if you want power look for something else. They come from factory so well tuned that mods don't do much for them.

 

[Vogz]

Both 3.5s and 3.7s are pretty stout. The 3.7s need oil coolers to get oil temps down if you beat on them though.

I ran my stock 3.5 in my Z ~450rwhp for 3 years before I build the bottom end and added 150hp. Both my stock and built motors have been rock solid reliable.

 

[DanJ]

I liked it even better when you had that huge exhaust leak the night at that fire whatever restaurant. Sounded like a 3800 swapped 350Z

 

[Intel]

Supercharged

god I want this nismo in white.

 

[radioguy6]

i have not seen too many 370z's but i love them. I've considered getting one to replace the G

Good info!

Also, what about the transmission options?

There's the 6m, 5a and 7a?

Automatic sports car

 

[radioguy6]

both the autos and manuals in these cars are really good. Just be careful with the 6MT 05-07 G35s and 6MT 05-06 350Zs with the "rev-up" engine. Some of those engines have oil consumption issues.

The autos are solid and run similar times to the 6MT with a good driver. I know the jatco 5AT is shared with the Nissan Titan. The 7AT is actually geared quicker than the 6MT, but for the 370Z/G37 no doubt get the 6MT.

if I went with an aftermarket exhaust it would definitely be a Nismo catback w/ a Y pipe off a VQ35HR G/Z.

Do you want a y-pipe from a G37 coupe? I have one at my dads shop. Its bent a tad, probably a easy fix. Insurance wrote a new one.

hmmm yeah but i dont think it will fit. The 37 exhaust is different than the 35. But let me do alittle research.
