You can also get a grounding kit for the trans.

 

I think I PM'd you about the 3.7 pumpkin. Do the gears, aluminum driveshaft, and Transgo valve body upgrade. Don't get too concerned about numbers. These three mods may not show much gains on the dyno, if it all, but they are some of the best mods you'll feel the most in everyday driving.

 

Osiris tune will yield you better gains than any of those other mods you listed. Be forewarned though, there's not a whole lot of gain you can expect unless you take the jump and go forced induction. Nissan did a pretty good job of squeezing the majority of the power out of these things naturally aspirated.

 

Well I would get tuned but there asking 800.. 300 for the license nd 500 for the tune

 

it was worth it for me, gained 15 hp and 12 tq off of mine. not to mention it is so much smoother and pulls harder throughout the entire rpm range and maximized the gas mileage. not bad for 800 bucks.



if 800 is alot then how much is it for a aluminum driveshaft and VB upgrade.... cause the valve body upgrade is around 700 for the transgo if im not mistaken...

 

For the both is around the same for the price of the tune the drive shaft 450 nd I can install nd the vb upgrade for 236 nd 180 installed

 

ok yea if you plan on doing the work yourself then you might as well do the vb and driveshaft. but holy hell 180 to install the valve bodies?!? that is cheap as ****. then we will discuss tune on the next thread you make for mods

 

This ^


In addition- you didn't just say the VB upgrade would cost 180 (to install), did you? Unless you have photos of the installer plugging into a sheep caught in a barbed wire fence you're looking at 500+ just to install. And even then if you're running extra HP on the AT you're going to want to get a cooler in there- no questions asked.

VB upgrade (transgo is the only one I'd even contemplate) was probably one of the best mods I ever did... tune was WAY up there as well and I think you alreay know not to bother with headers.

Sounds good though- especially if you do most of your own work! Geez, I wish I could! Save a bundle...

 

The installer said he'll do it for 180 because I always send him work he usaul charges 250

 

um... wow...

Most get charged 5-700... And don't get it done without doing the cooler at the same time. The AT despises heat. You don't need anything crazy- but at least get it upgraded so the lines are re-routed. If you talk to your transmission guy he'll likely point out the inefficiency of the existing system.

 

hey guys getting a great deal on a 08 350z differential will it fit my 03 5at ?? also is it 3.5 or 3.7 i searched and keep getting differnt numbers

 

if it has GC stamped on the top then it is a open diff with 3.5 gears(no lsd, found in all base model 350z 6mt)

if it is stamped GB then it is 3.3 5at with lsd (same gearing but HAS lsd, found in sedans)

if it is stamped GD then it is 3.5 6mt with lsd (found in all EXCEPT base model with 6mt)


so the one you are looking at will have 3.5 gears if it is out of 6mt. just check the stamp now to see if it has LSD or a OPEN DIFF. It should bolt up with absolutely no problems
