who can bore out a tb?

Sub'd!!!

I'm interested for sure.

edub370 · 12-19-2013, 09:31 AM

anyone know what all is involved on the tuning end of things to make this work?

i.e., is this like an exhaust and you CAN run without a tune, but it won't optimize gains, or will this be something that makes the maf read differently and throw things outta whack?

are we looking at ~5hp here or what?

I can't see a huge power gain unless the intake pipe and manifold inlet is similarly increased in size, and that's going to take tuning. At that point, the increase from the TB alone may be lost in the noise. I can see it providing noticeably better throttle response. While you're at it, you might as well cut off and weld close the coolant nipples, and ceramic coat the outside to ward off radiant heat. Now you've got quite a bit of cost sunk into a part that may not make a whole hell of a lot of difference. It's a different story if you can DIY it.

Why?

Chuck33079 · 12-19-2013, 01:02 PM

I'd rather not circulate hot coolant through the TB. I guess you could just cap them off, but if you're paying a company to do a "pro-quality" job I'd like closed up permanently.

Granted, some rubber caps would work just as well but, as long as you're going as far as boring and other mods, why not go ahead and seal 'em up?

Thats funny I was thinking about this the other day also and reached out to NWP that does a lot of stuff for vq35. Plus they recently released big bore tb for vq35 cars. On the 350z/G it dynos about 15hp. According to them. My buddy has on his Maxima and its definatley faster than before.

Hello,

I miss my Maxima and all your wonderful parts. Do you have anything in the works for 370z ie: big bore tb kit?
--------------------

Thank you for your interest. We definitely hope to have some new products for the 370z in the near future. But our current products are keeping us very busy.

But we do have several potential projects on the table, but I can't speak about them at this time.

Please keep in touch.

Thank you,

No I get that part, it's the welding. Mine are just pulled off and left open. If I ever wanted to reinstall the lines I'd just blow out the tubes and presto, all clean.

Chuck33079 · 12-19-2013, 01:22 PM

Yeah, I'd rather not even have them there. The car's never going back to stock, and it's far from the most invasive thing done to it.

If I were doing the work, I'd be capping it off. If I were paying someone else to do it, I expect them to do a cleaner job than I would.

AzSpeng · 12-19-2013, 01:25 PM

Welding, machining, all of that stuff we can do in house

synolimit · 01-02-2014, 12:53 AM

Grimmspeed said no. Still waiting on Z1 to reply.

luigi90210 · 01-02-2014, 10:43 AM

Couldn't you use the 350z DE throttle body? Iirc that one is bigger than ours.

Alstann · 01-11-2014, 11:32 PM

AzSpeng, also something to note - we aren't the only market for this TB - we share throttle bodies with the GT-R. Same exact and everything.

If you can get some boring done for a great price, I'm sure you'll have the GT-R owners knocking down the door too. As I'm sure people charge the GT-R crowd an arm and a leg for anything.

AzSpeng · 01-11-2014, 11:32 PM

this was brought to my attention just the other day.

im ready to get it done...someone send me a tb.
