As a newbie to V6, I am looking for advice on helping with the lack of take off, low end torgue.
As a old Vette guy I am spoiled with the massive amount of take off torque. What can I do to help off the line with my G35 Auto?
Mid and upper end runs wonderful, i love the car, just need a little help off the starting line.
I have a G35 Auto, with 10,500 miles, prem tire and wheel package (which gives me the 18" wheels and more import the limited slip diff).
I planned to add a crawford plenum, CIA, and maybe headers and true duals.
Will a stall converter help with these cars? Can the rear gears be changed?
Any advice will be greatly appreciated from a new import guy.
Thanks

 

All engine mods for the Z will work on the G...check out the Engine/Drivetrain forum on this site.

Are you headed out to our G meet on the 14th?

 

Looking forward to it. As a American Iron head, I might be a little lost at first. I have to say everyone in this forum have been very helpful.
Thanks

 

Most, if not all, the mods you listed would end up helping you gain more up top...

 

So what can I add or do to improve lauch time or torque?

 

I think the only thing that will REALLY make a difference is forced induction. Most all bolt ons will help the top end out. Nobody has really changed out the gears yet, so I can't really comment on that. But I think 350Evo has some in the works.

 

Thanks Moog for all the advice. Do you know a good tuner shop in North Dallas?

 

Well right now one of the potential sponsors of our DFW crew is in process of getting a shop dedicated to the 350Z and G35. He's a great guy...been in the industry for 8 years. David over at www.350zforums.org. He's also a sponsor of this site.

I used to work at a shop called Intercrew Auto Salon in Richardson. We worked on any car, and Phillip is a nice guy...very knowledgeable in engine building. 11 sec all motor CRX...they have a dynojet 248C also.

There are quite a few other shops out there, but none really that I would trust. They all have their horror stories, but Jotech is a big name in the area. They've done a couple turbo 350Zs. Lone Star Performance in Garland usually works on domestics can do a good price on the ATI supercharger for us.

We can discuss everything in much more detail at the upcoming meet.

 

If I am off i might try and make it. How far is this meet from allen?

 

It's pretty far from Allen...Euless to be exact. This is our official quarterly meet sponsored by Grubbs Infiniti. It will be a very nice meet. We'll have some reps from ATI come to discuss the procharger, David from 350zforums.org will be bringing a bunch of products as will I, they'll have a new QX56 on display, free continental breakfast, most likely will have door prizes...the list goes on.

I dont know the name of the place..[do a search on all forms] Thats where I seen it. They do have a stall trq converter out and there is smaller gears for the rear end .Looking to put trq converter on my self after the SC install

 

Although not Vette-like, the G35 seems to have plenty of low-end torque. Your comparison of your new G's low-end torque to your old Vette, while understandable, is a tad unrealistic. The G35 gives up over two liters in displacement to the recent Vettes. (insert Captain Obvious caption here) Short of shoehorning an LS1 into your G, your only real option is forced induction. (as others have mentioned) You're in the right area to explore that option, though. Good luck with your new G and welcome to the site.

 

Frisco - As a former Lingenfelter 'Vette owner, I know where U're coming from!! In fact, the only reason I chose my G over another Corvette was it's back seat ( for my grandkids ). My
( almost ) teenaged daughter's mad at me for NOT going with the Chevy as she wanted Daddy to give it to her when she gets her license - SURE I would!! Anyway, I had Level 10 restall my T/C to 2800 rpms & it's helped ALOT!! Also, Gurgen & Dave had a Cali company called Edge Racing do the same for them with similar results. Now I'm waiting for B.J. @ 350EVO to call me with a price on a 3.91 geared; LSD equipped differential for me to install via the "plug & play" method. I'm keeping my old "pumpkin" & gears in case I need to reinstall it after I do a T/T or S/C setup ( won't decide until those kits have some run time on them ). FWIW - I'm planning on having Texas Nitrous do an install ( 75 - 100 HP ) for me in March or April so I can at least hang with the Z06's around here until it's time to do the F/I system. Other than a T/C and/or gears, I see no other options for low end grunt. All my other mods seem to move the powerband up or don't really kick in until 4k + rpms. Still, the G is a much more refined ryde - just 2 different animals!!

 

Where is Level 10? I was also wanting to rebuild the TC to raise the stall. My G comes with LSD, but not sure the gear ratio, it is the 18" Performance Package with LSD.
I talked with Grubbs and plan to do the ATI kit in a few weeks.

 

Frisco - Level 10's up in New Jersey. If U call or E-mail them, ask to speak to John. U can count on about a 5-7 day turn-around ( at best ) if ya Red Label the parts up there & back. To reduce your downtime I'd suggest U have Grubbs drop the tranny while they're doing your Procharger work & do the work inhouse. The T/C restall cost $498 & I also had the valve body recalibrated for firmer/quicker full throttle shifts for an additional $698. The V/B work should allow the tranny to handle more power & run cooler ( offsetting the extra heat generated by the looser T/C ) so when I add the nitrous ( & eventually the F/I ) I'll be ready. Let me know how the ATI job comes out as I might have Grubbs do mine ( if I choose the S/C route ). Wish I'd known about the meeting this weekend in time to make it. Perhaps I can catch another one later this year.
About the gears - I THINK we have something along the lines of 3.23's in the auto-trannies.

The G35 meet is next weekend on the 14th.

 

Moog - Thanks for the heads up BUT I don't think the boss ( wife ) is gonna let me road trip on Valentine's Day!!
