400 HP is easily attained with the aformentioned parts, mostly the 11.5 compression pistons...however...do you really trust the tranny? just a small point id bring up. I know the ATs are as fragile as glass and cant take much more than 350, so i would look into that closely before you make that leap.

 

350? the Q has 345 or 340 HP rght, and I haven't heard of any TL nightmare type issues with the Q or actually cant remember anyone mentioning an AT with a real problem at all. The 6 speeds sure suck for some tho based on all the grinding and new tranny's getting replaced. Thats one reason i got this car!~ the tranny comes from the Q

My AT tranny thumps into gear from 2nd to 3rd in manual mode...I hope it doesn't break =)

I say that the original poster should remove the VQ and add the VK. It may be a tight fit but with a simple stroker kit, can get about 400hp N/A. Ooooooorrr you can set the rev limiter to 12000rpm. Both can probably get you 400hp N/A =)

All transmissions re speced at the torque they can handle in this case[Jatco JR507E] is rated for 333 lb/ft [450N/meters] for 100,000 shift cycles........assumming at the shift the power is decreased by 50% from ignition retard.

The maximum AT input shaft rpm is 7,000 rpm!

Q- define a shift cycle if you would. Does this mean that I could drive to work and go through 100 shift cycles on a long commute and have to replace my tranny in under 2 years?

<font color=blue>The above statements are only my take on the issue. If you disagree with anything I typed then you are 100% right!</font color=blue>

 

The stock engine, of course, does not produce 333 ft-lbs.

Q said 100,000 shift cycles at 333 ft-lbs. Does your engine produce 333 ft-lbs?

No, mine produces 280 ft.lbs. (at the crank with 301 bhp) I missed the 333 number. That still doesn't explain what a shift cycle is... and how it equates to various torque outputs.

No it is not. The car GGGGGGGG is referring to is not TT, and it is around 500HP "NA". Also, it is the VQ35, not VQ30 as GGGGGGGG suggested.

 

I take that back!! Getting the original post confused.

I heard that the original version used the VQ30DETT, but a newer car will use a NA version of the VQ35, and be closer to 500HP. I cannot confirm this, but it was in a small article in a recent auto mag.

 

I would LOVE to get my G35 up to the 400 mark using N/A and FI. FI would be a last resort for me. I don't want to spend the 6 grand + have the risk of the engine not lasting long. Anyone have any ideas?

Thanks - Joey Avino

You're wrong. Team NISMO has 350z with VQ30DETT making above 500hp.

Good news is that last season they used GT-R and this season they switched to 350z. Quite succesfully too.

Yes sir absolutely, the GM GEN III- LS1/LS6 motor which is a 346CI, 5.7L V8 is still around with pushrods with crank in the block technology why? Because nothing that infiniti, nissan, lexus, toyota, etc make that is supposed to be "new technology" DOHC, CCTI, IVTEC, blah blah blah come close to the raw power output of this motor. Simply put the LS1/LS6 by GM is by far the most advanced pushrod engine evr made.

Look at it this way.. Stock 01/02 Z28-SS-Trans AM- Formula - Corvette engines are all the same exact engine. Producing roughly 375 FWHP. Before you book worms jump in ohhh but motor trend said this and car and drivers said this, and the window sticker said this.. go actually DYNO one. I have the pleasure of owning a 2002 Camaro SS (last year made), and this beautiful infiti G35X as a daily driver. I dynoed my car which is a six speed SS stock and came out with 317RWHP and 338 RWTQ with the paper air filter in there.

So after some heads, cam, headers, pullies, and an exhaust with some tuning, I am putting out close to 460 RWHP and 408 RWTQ running mid to low 11's in the 1/4 mile NA!!!

I would like to see your mentality in explaining how is a motor that is "34 years old" out producing power at EVERY band over anything that came out of the above mentioned companies?? Even their V8 models dont come close. So I would appreciate it that you not belittle an engine that you have no idea about. Want power? go buy a used 98 vette for 18K, drop in a LS1 Stroker 427, with Fast intake, LT Headers, Heads, cam and a bit of tuning and you have over 500 RWHP and over 490RWTQ Natrually Aspirated.

By the way RWHP is approx 600 to the crank in a motor which is NA vs, the most you will ever see after a ton of money on the Infiniti motor is 450ish NA.

Now back to the original topic after i am off my soapbox now lol... Yes I have a kit on order to be built at a local shop here in vegas.. heads, cams, stroker with headers kit on this baby... i am expecting around 400ish wheel HP.. not bad for a daily driver. Will let ya peeps know how it goes (sucks to buy 800 bucks for injectors though lol).

ETCC E46 320I makes 275hp.

sununix,

according to whp/L and wtq/L ratios I saw from my G it could be making comparable numbers with 5.7l displacement. Makes me wish there was G57 coupe
