Anything that bolts onto the VQ35DE internall or externally (Dependent on chassis clearance)

Speculation (Try at own risk)
Brake swap
Rear Camber Arm

M35-M45 Exhaust Compatibility
Radiator

Does Not Fit
Air Filter
Cabin Air Filter
Front Upper A-Arm

BUMP! I would also like to know a list of parts that are interchangeable. How bout coilovers that were meant for the G35 coupe?

so...
y-pipe confirmed
High flow cats confirmed
z Tube - confirmed

I haven't messed with suspension yet mainly cause my wife doesnt want me to put my z coils on the M

Gonna do a test of 350z stock suspension on an M. From the looks everything matches up. We'll see how it goes and what kind of drop it will be if any. Pictures should be up this weekend!

i looked it over when i was installing y-pipes this past weekend.. it looks very similar. however one thing i noticed is even on the rwd M35 the front lower control arm and knuckle is different from z/g.. instead of a seperate control arm and compression arm it is a triangle arm on the m. the other thing i noticed was the upper control arm and wishbone is different as well on the M...


marcus.. can't wait to see before and after pics of the M w/ the Z suspension.
what yr is the suspension from cause in mid 04 they revised spring rates and such..
Also.. are you swapping dampers as well or just springs? Let us know how it rides.. Thanks

what up guys...here are a few items (stock and aftermarket) -- Keep in mind that I have the M35 sport, so unsure of some suspension fittings for M35x

upper and lower plenum
plenum spacer
wheel spacers


-- unconfirmed:
radiator (would like to run Mishimoto on mine)
shocks (front/rear)
engine mounts

100% no. I have been under there and seen them and The M45 is completely different in its rear end drive area. To start, the input shaft to the read diff is larger. Then the rear differential itself is much larger and has a different bolt pattern, the spline count is also different. The output shafts going to the wheels are also much larger, different bolt pattern and spline count and length.
Now thats not to say you cant get it done, you just need to modify the mount a little bit and also buy the rear axles and replace those at the same time if you swap the differential in an M45.

As for the M35, it should be 100% bolt on compatible with the G35's and specific year G37. I say should, because I havent seen for myself all the years of those cars and dont know for certain that everything on all years is the same. My G37 rear differential came from the single year you could get a G37 with a 5 speed transmission, the same 5 speed that our car uses. I have no idea and doubt that the models from the 7 speed transmissions will be a direct bolt on.

I was hoping my 05 g35 diff with VLSD fits my 07 M35

I will soon test fit on my M35 the following g35 parts:
Stance coilovers, Megan rear toe arms, and SPL camber arms, Megan UCA

sweet.. so i updated the list..
lets see what happens with the suspension compatibility

It's coming off an 03 so it's not the revised suspension. I'm not doing the struts as of right now but I will be taking some measurements so I could go with them if need be in the future. Should be happening Friday and Saturday.

So with the limited supply of reasonably price body kits for the M's, I have been wondering if any of the lip kits are interchangeable... Has anyone attempted to test fit a lip kit from a G35/7 sedan on a M? I just wondering...

This is also something I'd be interested in. I had an old 350z lip I had laying around that wouldn't have fit at all but a G35 or G37 might be closer.

The width on the G's is actually pretty close to the M. It might actually work with just a slight bit of modifying.

From Wikipedia:

M 06-10
1,798 mm (70.8 in)

M 11-
1,845 mm (72.6 in)

G 03-07
1,815 mm (71.5 in) (coupe)
1,750 mm (69 in) (sedan)

G 07-
72.9 in (1,852 mm) (convertible)
71.8 in (1,824 mm) (coupe)
69.8 in (1,773 mm) (sedan)

I don't actually know where this is measured from I assume whatever the widest point is.

I was able to fit my stance coilovers that were on my '05 G35 coupe on my 2007 M35! Direct bolt on with no issues.

NICE!!! Knowing that the G35's have sooo many suspension choices...this is good news. My buddy says he has the Tokico HP (blues) shocks/struts and his ride is excellent (06 G35 coupe) -- also lowered on springs..... I may have to give these a try....hmmmmmm

Did it drop you too low? I thought I read somewhere that Z/G coils at the highest height are lower than M coils at the lowest. Do you have pics of it afterwards? If this works it could open a lot of different options for coilovers besides the usual D2/Megan.

one of the concerns is the weight. especially w/ the z/g shocks compared to the M it has an extra 500-1000 lbs over the g. This could cause a crappier ride quality.
Coilovers i wouldnt be too concerned but when going w/ oe style shocks that are not damper adjustable could be an issue.

Def wanna see what stock z springs do on the m

frikin X version - what a pain in the @$$ - i need to replace my suspensions and the front sets are about 400 shipped. it seems there aren't any interchangable parts from the older Z or G coupe/sedan.

what the hell!!!

have you looked at the g35X shocks? they might be similar knowing nissan/infiniti

I have but no way to know for sure since i have nothing to compare to and i don't want to buy the parts that end up don't work

Marcus123 wrote: If this works it could open a lot of different options for coilovers besides the usual D2/Megan.

there are a lot more than those two for coilovers, Jic magic, Tanabe's new 40 way adjustable, Tein has a couple different one's, K sport, BC racing and then there's some in Japan that no one really gets like Rs R and Impul just to name a couple.

So after a car show this weekend where i was takling w/ a fellow M owner.. It appears that.
350z / G35 front brakes do not work without an adapter
370z / G37 Front brakes bolt on

350z/g35/370z/g37 rear brakes all work..

Anyone want to double confirm my findings?

does that include the brembo brakes?

yep g35 brembos dont bolt on and g37s akebono's do, personally Id get the bigger of the two if I was debating. Also Evo brembos bolt on with a custom adapter along with mercedes amg 8 pot. Ohh and there's some brakes fs here http://york.craigslist.org/pts/3206242131.html great deal too!

CONFIRMED. none of the Megan racing Y-Pipes will fit in an M35x. straight from the source.

We do not have a Y-pipe that is fits your AWD application. Please check your local laws and regulations regarding emissions legalities. It is definitely illegal in the state of California to remove a functioning catalytic converter.

This being confirmed, can anyone help me out with my options. I'm in desperate need of a new y pipe for my m35x and im not really looking to buy a new or used OEM, but if those are my only options...i have heard that the FX35 y pipe fits the m35 (non-awd), possibly would the FX AWD fit?..looking forward to hearing from you guys.

thanks,

I believe you will need the ypipe from the G35 VQ HR style. The HR style has a wider look than the "DE" style.

Take a look at this thread and you'll see the HR style ypipe. also Megan makes the HR style ypipe

I looked at the parts on ebay; specifically megan parts number for m35x and g35 hr motors and y-pipe as well as hfc are the same. Of course i haven't buy the part to test them out yet. They're cheaper compare to the rest after market manufacture so it might be a ''cheap'' investment to test :-)

I agree that the HR style y-pipe from megan looks a lot like the current y on my M. but i emailed Megan racing and they specifically told me it will not fit. i mean, should i just buy it anyway to see if it fits, even though they told me it would not?
