so you ruined a good stock product when you were going to get the lung tubes. Now if you need to go back to stick ones you will have to buy new ones. I could see if you werent going to get others but you are. Not mad at ya tho, just not the way I would have done it. So how does it sound and perform?

sounds like a good idea. Thanks.

I said the same thing to him... He bought a second set of stock ones, and gutted those.

its not about the money, just havent seen anybody else try, so ill be the first. yes its a pain, as for the sound/performance prolly just like test pipes. no i would not do it again, just buy a set of 200$ test pipes off ebay. now back to topic the gears...

tranceformer · 05-08-2010, 08:16 AM

I supervised and took pics, Jason did the rest.

one other thing, I have a SPL diff bushing set from when I had my 350Z, never got around to installing it or even selling it. Kuah@SPL assured me that the front bushings would fit and the rear would stick out a little bit since the 350Z rear subframe is a little bit thicker. Last night, we checked it while we had the diff out. Everything looks good, I think I may end up keeping the diff bushings for my Z.

all done....tomorrrow ill post all part numbers of everything you will need to do this.as for the srm works perfectly except its off about 2 to 3 hundred rpm but it is very close. cruise control works perfect. no ssues at all. it is deff not to radical of a gear, sooo much better acceleration down low in the rpms where we have no tq.

tranceformer · 05-08-2010, 11:49 PM

Wouldn't having the crank pulley and fidanza flywheel contribute to the SRM being a little off?

Either way the gears definitely made a difference, you were pulling about as much as you were last week but this time you had a passenger!

btw, we need to get some walkie talkies!

So still good as a DD? So will this make your 0 to 60 and 1/4 mile times better?

I'm curious to how much the SPL diff bushing kit transfers noise to the interior.
