I have seen several dyno for this vehicle, the normal is about 260-280....so he is saying with "just a tune" no other supporting mods, just a flash, he is making over 120rwhp? The DME tune for these vehicles barely gets you close to 350rwhp

It's just not something I'd do (just flash the ecu without supporting mods). I had a turbo car before and I replaced the exhaust, intake, and intercooler before messing with the ecu. Idk much about the stock 335/135 intercoolers, but even people who dont up the boost go with FMIC's.

Are we really going to talk about what might happen with the VVEL? :ugh2:

I am well aware that the tuning just ups the boost...but I don't really care where the 100 bhp I picked up comes from. I don't know what I could have said to make you this angry over it, but I think it is more fun to spend a couple thousand dollars or so and pick up almost 200 hp at the crank (Tune + Methanol Injection + Bolt Ons). What does $2000 bucks get you in the Z...30whp? That's what I'm saying.

I have seen dynos from 265 to 275 rwhp stock, producing 345 to about 355 rwhp with JUST a tune on map 1 @ 13 psi. Map 2 is 14.5 psi, and map 7 is more like 16-17 (I can't remember) but you need 100 Octane gas at a minimum. For map 1 and 2, you really don't need to modify a thing.

Said almost 400...which is around 370-380 at the wheels. Here is a dyno with lower boost setting and only intake and downpipes.

Here's another with high boost map, upgraded FMIC, intake, 100 octane, and full exhaust.

well i have only spent $789 and already gained 32rwhp. dont even have a full exhaust, tune, pulley, manifold, no VVEL tunning or Adjusting ie CAMS heads, no headers...pretty bare bones here

Is this thread seriously still alive? Face it, they are both great performance cars - stock or modified. Total amount spent (including the car) will net you a similar result on either car, or at the very least the result you're going for if you plan your mods right.

The difference really is in the styling. One car is for dicks who like chicks, and the other is for chicks who like ****. Not really much else to it.

What's your torque curve look like?

You have a Mazda Protege...

As my daily driver. Not that I need to justify but:
- It's also one of only 2000 ever made
- And one of the first 600 MazdaSpeed vehicles to be sold in the USA
- It made over 270WHP at it's peak (and only weighed 2800 lbs with me in it)
- Now that I ALSO have a 370z my Mazda is detuned to only 8-10psi and making a more conservative 225ish WHP.

However, if you'd like to see how your car does against my MSP I'd be happy to turn the boost back up to 13lbs and leave you behind on the highway. Trust me, I have both cars and the Mazda (when pushed) is definitely faster than my 370 was when stock.

And I'm not hating on the 135. Like I said it's a great performance/luxury blend. But in my personal opinion the styling of the Z is a night and day difference.

not to bad i gained, 25rwtq...the y pipe bieng the main contributer. I have the dyno here somewhere in the intake/exhaust section....my car is all motordyne parts...just waiting for them to release a full exhaust and thier intake so i can finally get a tune. I enjoy a good discussion :tup:

would love to have a friendly run with you man, where are you located?

Dallas. Anytime you come up let me know.

Like I said the MSP is detuned now so I'd need a few days to get to my tuner to upload the old maps onto the Unichip and mix up a batch of the old home-brew 105 octane blend. And she's 8 years old now with 120K hard miles on her so it's would be just a few short runs, but she'd probably like it if I brought her out of retirement for a little bit :)

And Push... I honestly meant no personal offence on the styling comment. I do drive an orange car every day, which seemed like a good idea 8 years ago when I was in my mid 20s, but doesn't really put me in a position to knock anyone else's styling preferences. :tiphat:

And I do love the motor in that thing. A girl I'm dating just picked up a used 335 and we've begun the modification process on that. You're right on the ease of power additions, no doubt about it. I spent probably $3K on my Mazda and picked up about 150whp. I've spent a little under $2K on my Z and picked up maybe 30whp. If only they were all so easy!

The BMW is my daily driver too...and the 135i is substantially faster than a 370z with any bolt on. Can it beat your Mazda? Probably. Do I care? Not really. ;)

I recently did a friendly run with my friend who has a 335i 6MT and a JB3 tune and pulled on him with the mods listed in my signature (haven't gotten an updated dyno run since the CBE). Different cars for different purposes, if he added some bolt ons and a more aggressive tune then the tables would be turned for sure.

Supercharger and turbo kits for 370 Z technically bolt on. You lose. One series econo cars have some real flaws. I'd rather have a mildly boosted Z.

They don't. Some might call a Nissan badge a real flaw ;)

When I had the Z, somebody actually told me they liked my Altima once when I was filling up. Yikes...

I'm pretty shocked at the animosity from this forum. One of your own (09 370z owner for over a year) leaves and gets another car and all of the sudden everybody gets all defensive over a positive review of a half-competing vehicle? I never attacked the Z...just said the 135 is much more tunable and that makes it fun for me. Unless you guys are going to have your 370 for the rest of your life, cut the crap. There are better cars. Even a 5.0 Mustang can kill a 370 on the track right? A Mustang! I honestly never thought I'd see the day, because I was always one of those "american cars are only fast in a straight line" people.

I wish the Z had a motor like the one I have in my 135 because it would pretty much be the perfect car, and I'd still have it. It doesn't, and for me, I prefer to have a DD that is comfortable, knows what torque is, and when I track it...minimal modifications should make it keep up with some substantially faster cars when stock. That is not the Z. That's why for me, the Z was not the right choice. It might be for you, and good luck.

Sorry man, motor vs motor there is no way in helllll the 135 is better, not a chance. The only single or should I say "twin" reason the 135 is even note worthy or a contender in a way is because its twin turbo charged. Other than that, mod for mod(na vs na), turbo for turbo the 135 will get left. No animosity here, and about the 5.0, that motor is marvel, idk anyone on here thats not in tune with that. So when you say "a mustang?!?" This isn't your regular car, the NEW 5.0 "mustang" is nothing like the previous and will hand just about any car its *** on a platter

Yeah unfortunately a used 135i is all I can afford :(

I've had my Range Rover since 9/2007 and it has been in the dealer exactly 5 times...for oil changes. I clearly didn't buy a 5500lb SUV to be a speed demon. Next time when I buy a car I'll make sure it's up to your manly standards. Oh wait, of the 4 other people I know of with a 370...guess how many are guys? Two. One of them is a freaking stripper. Does that make it a chick car?

Yeah, the 7AT's are going like hot cakes to women, you've got me there. When I called around looking for a 6MT they were actually hard to find. Everyone had 7AT roadsters. Anyway, I was stuck in traffic next to a 128 today. It was driven by a really hot brunette (not that it matters - I was just messing with you), and it was nice. It just reminds me too much of the Merc C230 Kompressor hatch (not in looks, just overall impression of the car - the 135i is certainly more appealing due to the power). Now that car was publicly marketted towards young urban professional women. There were press releases that said it. Whenever i saw a dude driving one i just laughed. But at the same time, when I see a J-Wow look-alike with fake tan, fake boobs, fake nails, etc rockin a denali with 22's or a Hummer (Jersey trash - happens all the time) it's pretty sweet IMO.

I also was reading that the 1 series got complaints about there not being enough legroom on the driver's side (more apropos to manual than auto models since you have to be moving your entire legs not just feet). Have you found that to be the case? I played D1 football and I can just fit into my Z in a race driving position.

I'm not exactly a D1 athlete, but I'm about 5'10 or 11 and I can put the seat far enough back to where I can almost not even reach the pedals. I don't have an abnormally long torso or anything either...inseam is like 32. The back seats are actually pretty comfortable too. I wouldn't sit back there for a road trip by any means...but they are actually usable around town unlike the Mustangs. It's a "small" car in that sense...but that's kind of what I like about it. The inside is not cramped in anyway, I have more headroom than the Z, and it's really easy to park in tight spots if need be. Supposedly the inside is basically the same size as the previous generation M3. Plus I can scare 3 people now instead of just 1.

What about the area under the steering wheel? Like how much room do you have between the top of your legs and the bottom of the steering column? I think that's what the reviewers were talking about in terms of leg room. I'm not tall either, only 5'10". But I played ball at 235 and I'm almost 250 now and I have really big thighs so when I move the seat up for racing i can just make it in the Z but for daily driving it's fine.

No defensiveness or animosity, just a better knowledge of both platforms than you.

The 1 series platform has some real suspension issues well known in the motorsports world. How many 1 series do you see racing in Grand Am? Or any other serious series? Teams have made assessment and have said no thanks to econo box suspension on this overweight car.

I havent met a track yet that doesnt put a premium on HP but given new Mustang holds nearly 100 hp advantage and a 370Z Nismo can equal it or even better a mustangs times on some tracks I think that is alone indicates handling superiority of the Z. Also very clear AX guys in US made pony cars dont want the Z to run in their classes - most of them say the Z has a suspension advantage they cant overcome. LOL!

135i is very nice little econo car but its overpriced by about $5K. Seems like your trying to justify the purchase to us? I can understand how you were seduced by nicer interior and turbo power, but the car falls flat on performance side for serious drivers like me. I spent plenty of time in the 135i and honestly can say I was impressed with it as a commute car but not as a track enthusiast car. Lots of people outside of the 370Z world concur with that opinion.

Can we close this thread now its sort of getting boring.

No clue. Can't be too bad if I haven't noticed it?

You got me there...I can't argue with somebody who is a super important professional racecar driver. Get over yourself!! I have only said the 135 is great FOR ME because I use it as a DD and will be tracking it. It's fast as hell and is going to be a lot of fun on the track. No need to turn into a jacka55 over a former 370 owner simply sharing his experience with a different car. I'm excited to see just how it compares time-wise with the 370 on a racetrack. I wouldn't be surprised if the 370 can outhandle a lot of other cars (especially the 135) in a parking lot.

I really don't understand this at all. Never talked $%&# about the 370. I loved mine a lot, and still do. I don't think there is any question I didn't buy a little BMW because it was a track beast...I got it because I didn't want a fourth car, it's roomier, more comfortable, and better in traffic where I spend 99% of my time. It's just a bonus that a thousand dollars can get you what it takes ten thousand to in the Z.

Can you name a single person that has blown their turbos (w/ proof) because of the tune? I'm on e90 a lot and I can MAYBE count one or two (and it wasn't tune related ;)) It was oil starvation from a faulty line to the turbo. He knew it was bad and had problems with it in the past. Seriously though, the stuff you spew is what leads to these "zomg" rumors.

From one 335i owner to another... 360rwhp is a bit stretched. Maaaaybe 350 at 12-14 psi tune only. Our cars dyno stock around 260-290 depending on elevation and conditions. For example, in Houston I dynoed stock at 282, after tune I was in the 330 range at 12psi. After I installed my dp's, fmic, exhaust I was around 380-390. Then w/ meth I can jump above 400rwhp on pump 93.

8 psi is stock boost. 360rwhp is far-fetched from tune only. See my post above. Now don't get me wrong, at 15-18psi you can easily be 350-390rwhp, but without any supporting mods you're raggin on the engine.

The piggybacks, a la JuiceBox, Procede, COBB, net a lot more than flashes currently.

Agreed...I was running 93 octane at about 14.5 psi. On my 135i they dyno at 340whp with 91 and map 1 on JB4.

I have a meth injection in the mail ;)

Sounds like a logical choice for you. No argument there.

Your approval just made my day.

Yeah, but you still lost to an E36 M with bolts on :tiphat:

I just sold my Z for an 09 335i coupe... I don't regret it at all, but comparing the two is silly and will never end..especially on a Z forum.

On the BMW forums the discussion was at least civil. Don't you f'ing love that N54 though?

Yeah man... the build quality, low end torque and comfort are way better.

I got an 09 coupe for 32k... with 8k miles. They guy never serviced or drove the thing so it's at the dealer now getting all the services done (which are free :))

but yea driving it before that was... awesome.

I dont think anyone disputed the build quality and comfort nods go tp BMW. Thats not the MO of a Z. The Z is a pure sports car in every sense of the word. The 335 is more of a touring car. I like them a lot. If I had the scratch it would be at the top of my list for a daily driver, in white w/ red interior and black rims with a polished lip. And I'd make my Z a full on time attack car.

Getting them used is the way to go. All the German cars are grotesquely overpriced new.

Kudos on your purchase! Enjoy it!

I don't think I'd really call the Z a pure sports car. It is a bit more raw than the BMW though.

:iagree:
It does have air conditioning and a cupholder...

3 cupholders at that!

Aside from a GT3 idk how much more pure of a sports car there is. 2 seat, rwd, stiff oem suspension, light curb weight, not too much effort placed into sound dampening, etc...

Hopeless impracticality doesn't make a sports car more pure

Right now, there's not much available that I would really consider a pure sports car. Perhaps a Lotus.

The Z weighs over 3000 lbs, comes with a VLSD at best, etc. I thought even the S was a bit watered down, and it came way closer to being a sports car than the Z does.
