MD Spacer + BTDC17 today. Should be interesting.
So this is both intake and tuning based, I guess...so I thought I'd just put it in this section.
I'm about to have my 5/16 installed today, and then heading over to my friend's house to get the timing redone to 17-degrees via Consult II. I had the BTDC@17 performed on my 5th gen Maxima, and it worked extremely well on the venerable VQ30. I'll report back with impressions. I may also get the JWT PC installed sometime in the next few weeks too as the last performance mod for the year.
Nismo exhaust and y-pipe will likely come at the end of the winter.

The spacer is in. Took us 1 hour, with rxkevin doing most of the work and me assisting. Definitely PM him if you need any parts for your Zs. Outstanding guy.
So yeah, I haven't had a chance to really test it yet, seeing as how Kevin only lives 3 blocks away from me. But I do feel a punchier low-end (2-3k RPM), and the engine note is a little louder as well. Again, impressions are based on the 30 second drive home. LOL. When I head out to my friend's house, it'll be a nice 8 mile drive - so I'll report back. =)

Well, I can honestly say that I'm blown away by the difference this spacer made. I really can't believe something this simple achieves results like this. I honestly went in with low expectations, thinking I wouldn't feel much. So after a few test runs through the first three gears, I can honestly say that the power increase actually scared me a bit.
I had adrenaline running through my legs for quite some time after I had stopped. You can feel a power increase from about 3500RPM, but everything past 5000RPM is simply incredible and redline comes before you even know it. Damn. Just damn.
Thankfully, I was able to test it out right behind my girlfriend's house, on a fantastic straight patch of road with no cross streets, houses, backyards, driveways, no shoulders for cops to sit on, no cars, nothing. It's a wide two lane expressway parallel to a highway, and this particular stretch is closed off with sound deadening walls on each side too. Really a great place to stretch the car's legs.

Differences I've noticed with the BTDC17 is improved low-end torque. Furthermore, as if the car wasn't already punchy in higher gears, it is even punchier now. Cruising in 5th gear feels stronger, and the same goes for 3rd when you're around the towns.
Also, downshifting creates a larger burst, which feels especially nice, so there's clearly some top-end power gained. WOT with downshift induces some traction loss in 2nd gear. I felt it with the TCS off, and then confirmed it by turning it on and watching the SLIP light blip once - this has never occurred before.

the advance should go throughout the curve. the way to prove that is to retard the base timing to something around 10 to see that the car feels like junk in every rpm, not just the low end. i used the autoenginuity to do that on my g35 and it was very noticeable.

Seems like your a$$ dyno is WAYYYY optimistic-god forbid you ever ride in or drive a FI Z you may shart yourself...Glad your enjoying the mod-but add the 03' lower collector and the TQ in the midrange will be much better. You dont need to buy the MD one, just add a stocker it will provide 95% of the gains-the machining on the front 2 runners isnt a huge deal. Im buying a stocker for my GF's Revup, "machining" it myself and adding a spacer. MREV 2 for less than $400

Btw, I don't think I need a 287 lower collector. I have a 5AT.

In any case, I'm loving the improved low-end, really makes the car a lot more fun to drive around the town.

Arnold K. I feel you man... you were very surprised with the power gains. I know when I got my spacer installed in my 04 I had a HUGE GRIN on my face. The Z is a very fast car for being NA. I came from a sedan so for me a Z's power was scary...nothing wrong with that.
