So an UpRev reflash will give you the ability throw out the wiring harness crap?

I may be into this now.

Good luck!!!!

So, Mr. Envy here prob subscribing to this thread now.
It isn't for the faint hearted or people without spare time. I have spare time... I just have to conquer my laziness.

Front sump makes this a bit more work than a 'typical' swap... but I'm certain it will be WELL worth it in the end.

For fun... a single turbo stock motor VQ35 dyno... 8psi

Yup, the person tweaking the reflash can disable the security components and also kill check engine lights for secondary o2s and anything else you want.

Basically you end up wiring up power/gnd/e-pedal/ignition. Should be it.

In NA mode, about the same as the miata setup. Motor is Very close to same weight dressed as Miata. Transmission is a few pounds heavier (so says my back). But at least that weight is in the best place possible, low and central.

I'll try to weigh the transmission to get that #, as I haven't seen anyone post them up.

It should move some weight back too. Kind of curious what the corner weighs will look like after the swap is complete.

Quoted from http://www.350z-tech.com/zwiki/VQ35DE

"VQ35DE

[[According to Wikipedia]]

The engine used in the 35th Anniversary Nissan 350Z displayed exactly twice the output of the original 1969 Datsun 240Z

The 3.5 L (3498 cc) VQ35DE is used in many modern Nissan vehicles. It adds variable valve timing and has a bore of 95.5 mm and stroke of 81.4 mm. Output ranges from 240 hp to 301 hp (179 to 225 kW) and 246 ft·lbf to 287 ft·lbf (334 to 390 Nm).

The VQ35DE is built in Iwaki, Japan and Decherd, TN. It was on the Ward's 10 Best Engines list for 2002 through 2006, the only engine to be on Ward's list every year since it's inception.

The VQ35DE has an aluminum engine block and aluminum DOHC cylinder heads. It uses SFI fuel injection, has 4 valves per cylinder with VVT and features forged steel connecting rods, a one-piece cast camshaft, and Nissan's nylon intake manifold technology.

A modified version of the VQ35DE, called the S1 is produced by Nismo for the Fairlady Z S-Tune GT. It produces 300 ps or 285 hp (220 kW) at 7200 rpm - a higher rev-limit than that of the original VQ35DE.

The VQ35DE is featured in the following vehicles:

* 2001-2004 Nissan Pathfinder (240 hp)
* 2002-2004 Nissan Maxima (255 hp)
* 2004- Nissan Maxima (265 hp)
* 2003-2006 Infiniti G35 (260 hp to 298 hp)
* Infiniti QX4 (240 hp)
* 2002-2004 Infiniti I35 (255 hp)
* 2003- Nissan 350Z (from 287 to 301 hp)
* Nismo Z S-Tune GT 295 hp (VQ35DE S1 engine)
* 2002- Nissan Skyline (V35) (280 hp)
* Nissan Stagea (M35) (272 hp)
* 2003- Nissan Teana
* 2003- Nissan Presage
* 2004- Nissan Fuga (280 hp)
* 2000- Nissan Elgrand (245 hp)
* 2002- Nissan Quest (240 hp)
* 2004- Nissan Murano (Z50) (245 hp)
* 2002 - 2006 Nissan Altima (from 250 to 260 hp)
* Infiniti FX35 (280 hp)
* Renault Espace (241 hp)
* Renault Vel Satis (241 hp)"

Pretty cheap too.

Brand swapped cars can be fun (built a 914/V8), but who would you race? I mean the car would be fast, but there are no series to run it in compared to other options FWIW.

Sounds like HP tuner software with LS motors. That's a good thing.

Build looks awesome.

Why would I care about a race series? I got over the need to compete when I played sports all year round for most of my childhood.

Not to mention costs go through the roof when it becomes racing vs fun time at the track.

0 need to "race". Having lap times to help me figure out my improvement at a driver is MORE than enough.
