GRRRRR, I really think that you guys have to stop arguing about this crap. Lets just put it this way.....'03 Mustang Cobra. Smoke your M3 and your 350z. Granted, it could use a little refinement, but so could a vette. Even on the track you are toast.....

 

Exactly. And who cares about interiors, there's no place for dash moulesters on a performance minded site(s).

BTW, I highly doubt a Z will hit 12's w/ I/H/E and ECU.

 

whosdady- Are you sure that you raced the 315HP M Roadster and not the 240HP M Roadster? Visually you really can't tell unless you ask the guy wht year the car is. The performance #'s for the Z and the 240HP M roadster are very close.

 

I think the wheels are different.

I thought I may raise some eyebrows.

EG1: I am not saying all Z's will go high 12's with I, E, H and ECU upgrade. However, I do believe it is possible. If predictions are correct about the ECU upgrade it could unlock up to 30 HP alone. IMO that is high but those are the early estimates. Add on another 5 HP for the CAI intake, 13 HP for exhaust and 10 HP for headers. Adding those up you come to a total of 345 HP. Not bad! Then keep in mind that these mods IE headers will give more top end HP and the exhaust will give low end torque.

The weight of my car minus the jack and some other various non essential items is roughly 3200 lbs. Now look at the fastest times at the track with a stock Z. The fastest I have heard of is 13.67 or 13.76 I can't remember. With better tires not even DR's just better tires I would think a decent driver could hit high 12's...

Doesn't this make sense?

 

I tried not to reply to this thread but I couldn't stop myself. I owned a '02 M3 6spd then a 996 coupe, now an '03 track 350. The 350 is by far, again by, far slower than either of my previous cars. I don't care what any of you guys are smoking the M3 will hand it to you. As a previous M3 owner I can tell you that no M3 driver even considers a 350 competition. Yea you may play with one light to light but why waste your time? That said you may ask why would you go from an M3 to a 350?????? Money that's why. I want to be able to do other things with my money and I still want a cheap sports car. The 350 is a cool cheap sports car. I really like it but I have no illusion that it will ever be an M3 killer.

 

He's right guys... us being stock racing a E46 M3... we need to chill out.

Thou the E36 M3s??? Haha... BMWs sick joke to the US. We'll screw them all day long.

 

I'm sorry to hear that, because I did kill 2(two) M3's, and it was not a light to light race because we went 135mph+. My 350z is not stock (injen, grounding kit, no resonator) so I'm not saying that a stock 350z could beat an M3. Like I said earlier, I don't gain anything by lying, actually maybe I'm at the risk of loosing credibility here. But ever since I don't sell anything, and I don't really care what people think or say, you can either believe me or not.
Maybe you could do the math... if the M3 weights 3450lbs and the 350Z 3150lbs (base) maybe the numbers would be interesting for the arguments... and then ad the mod's to the 350Z and things get more interesting.

 

Do you really believe your calculations? What you are doing is adding each part on top of one another. There is no way that you will ever get even close to 345 HP that way. Each mod does not add to the existing modifications. You may get a totaly of 25-30 hp from the whole getup....

 

POOK is right. STOP Dreaming people. With a 50shot of NOS you will make things more interesting for the M3 only because of the instant torque you'll get from it,but come on. And JAVI, the mods you have are great but nothing to make anyone go WOW over. You can't change some wires, throw an airfilter on, and take away a pipe to see Jekyl and Hyde. Of coarse all these mods make little differences and good ones at that but not huge gains. Just like an M3 or an N/A car these BASIC mods are not huge gains. OK they say if you change the Z ecu you get HUGE gains, so I guess we'll see about that. I hope so.
Oh, and the older M3 coupe is one fast car! I love it. That has I believe around 240hp and in my opinion would still give the Z some trouble. Again, weight and GEARING!

 

Oh my God.... this thread is pointless... if the Z owners here actually race by a roll a late model M3 and lost for a couple a cars then you have the rigth to have a valid opinion, do not speculate about what MAY HAPPEn or SUPPOSE TO HAPPEN.

 

I think the Z can hit high 12's with intake headers exhaust and ecu, im thinking that should not be hard for this car. b/c they did make it under emission control for gas and stuff...wen some1 does it post it and tell us ur 1/4 mile.

 

GOOD LUCK!!!! POST THEM TIME SLIPS!!!!!!! Don't forget to frame it, because if you hit high 12s I'll frame ir and hang it up in my office for sure!

 

you guys are forgetting the fact that the M3 makes more tq at the wheels because of the higher redline, by staying in the lower gears, which multiply the tq that the engine does make more than the higher gears. Ignore horsepower, torque wins races but not tq that the engine makes but tq at the wheels. This is how a S2000 with 153 ft/lbs of tq can run with a 302 ft/lbs of tq Mustang GT and totally demolish a Accord with 152 ft-lbs of tq.

 

One of my neighbors has a new m3, maybe I should video tape us racing off the line, and from a roll. I have injen intake, I can get a grounding kit, and I have my resonator removed. I don't know if the 350z can beat one, I have never seen one in action. I don't really consider it that much of a higher class then the 350z, higher, but not that much higher.

 

Thats a very wierd explanation if ever I heard one.

So if a car revs to 19,000 rpm and has 110 feet of torque with 110 bhp it should in theory beat a Z06 right.........

All higher revs does is allow for more hp to be generated, its all a question of doing it within engine tolerances.

Taking an example from F1, raising the engine rpm redline by 1000 might result in an imporvement of 100bhp.

The M engine is quite a bit more sophisticated than the S2000 ie no 'dumb' vtech system that is simply set off by an rpm switch. The system continuously varies the amount of air the engine gets, optimizing it for rpms so you get a lot more power over the rpm range vs a normal inline engine.

 

I will try to make it easier for you to understand. The ECU by itself is rumored to make in excess of 30 hp. That means if you do nothing else to a stock Z but mod the ecu, you will have 317 hp. Then you have the Stillen exhaust system which has added up to 13 hp on a stock Z. Combine the Injen CAI which has added up to 7 hp on a stock Z. Then add the headers (which I have not personlly done) for another 10 additional hp to a stock Z. I forgot to mention earlier, high flow cats which I ordered today from Doug. These are good for another dyno proven 6 hp. And also add the new plenum (just ordered as well) good for another 10 hp. Wow, that is 360+ hp*. Now I hope you don't misunderstand me. Not all cars will get the exact hp out of each mod, but I feel the numbers will be within +/- 1%. The only major difference will be between the auto tranny and the manual. The manual will have less loss, thus more hp. The only major variable in this equation is what the ECU will do?

From your comment it sounds like you think these mods cancel eachother out. Maybe you are confused about hp vs rwhp. I am saying we will push 345 hp not 345 rwhp. 345 hp is only 286.35 rwhp power (average 17% drivetrain loss). Next time you read a thread, check out some of the sigs guys have. I have seen sigs claiming 260+ with only half of these items. Put the ECU into the mix and they will produce more than my estimation.

Maybe this is your first experience with a sports car? I'm not sure what they will be able to do for your G? I have seen a turbo kit in Japan but I doubt you bought the G antisipating a turbo install.

For the guy that said the M3 is all that Most stock E46's are dynoing around 270 rwhp. That is 270 rwhp at 3400+pounds. An average 350Z with a couple of mods will dyno in at 260 rwhp and weigh 200 + less pounds. It doesn't take a brain child to figure out who would win a race

 

The unladen weight of an M3 is 3415, that equates to roughly 3550 laden

I would still fear an M3 with SMG II though.

 

whosdady - not saying that it's unbelievable, but i can't see a Z without F/I keeping up with the newest M roadster. I believe you raced the old one... and for wheels, you can always change them. Didn't you see the thread on the Z31 with Z33 wheels? Lots of people with bimmers and mercedes change wheels, body parts and badges to look like the more expensive or newer body. I've seen the newest M roadster (completely stock) run a 13.8 or something around there, at a high elevation track. The fastest Z I've heard run there is 14.7 at the same track. Not saying someone can't run their Z faster at that track, but a full second?

 

No doubt the wheels could have been changed. And yes, to be positive I would need to ask. However, in my opinion it was the 315 hp,(latest version of the M roadster.

A 13.8 is no big feat. Granted I live closer to sea level but there are many guys in the 13's. In fact, I would say out of the track posts I have read, most of them are in the 13's

 

Umm, I would say you raced a 240hp M roadster... Which is a very low 14 second car.

315hp Roadsters are capable of 13.2's I haven't seen a Z come close to that mark yet.

Unless you know BMW's how could you tell it was the 315hp edition? Pretty hard to tell... Good story though.
