370z vs 335i Coupe

christian370z

Not in handling it won't, you still can't overcome a substantial weight penalty. Besides, if you start mentioning bolt ons, the cost savings of buying the Z versus a 135/335i is not exactly small. A couple grand invested in the Z and it would keep up with a 135/335i in a straight line (even or at least close) and would outhandle the BMWs in my opinion.

That said, I have a huge amount of respect for the n54 and how well the BMW packaged comfort and performance.

They are pretty much identical stock for stock. 0-60 in 5 seconds, 0-100 in about 12, quarter in low 13's. After just a tune, a 135i will leave a full bolt on and tune 370z in the dust...

It won't...at all. It wouldn't even be close. Plus, I bought my 135 used with same miles/year as my Z was for thousands less than I sold the Z for. The Z handles much better stock, and I'm interested to see how close lap times will be with my largely stock 135i suspension wise. I'm planning on doing a few hot laps with the stock tune first to see how it compares as the 0-100 & quarter times are identical on the stock 135 and 370. I'm probably going to end up putting sway bars and coilovers on it, but the first few sessions will be with the stock suspension.

LOL exactly. I had the same problem with my WRX. And the Evo's create that same disgust in me as well. The new 5.0 is a beast but they could have done so much more with the looks. Nicer rims (much like Nissan did with Rays, I'm sure Ford could have found a nice, deep dish American Racing wheel to offer on the sport packages) maybe a little lower ride height, and 285's in the rear...The interior is also nasty. That car NEEDS sport/racing seats with decent bolsters. And the retro gauge cluster has gotta go.

I think the Mustang 5.0 DUB edition took care of most of those problems

This is contrary to what I've heard. The 335 guys talk about heat soak and the need for an aftermarket fuel pump. If you're doubling the boost and using the same intake, exhaust, and intercooler I can't see how that's optimal. Is it impressive to make 400 whp on a $500 tune only? Hell yes. But I've had turbo cars before and have worked on many Mk IV Supras and even they didn't make that power without intake, intercooler, exhaust, AND a boost increase. BPU+++ was good for mid 400's on pump gas. If you wanted 500 and above you needed to swap for a single. And in terms of a road course, I doubt it. All that power and stock tires? Plus the Z out handles it stock...


And im not trying to be fresh, but I've never seen one driven by a man.

Push370zz I understand u love your car. I was in-between the nismo and 135 myself. It's a nice car but not a true sports car IMO. Didn't feel like one when I drove it. 400rwhp on a tune I call bs. Now I know a tune frees up around 60who on a stock motor so I say your at like 340-350rwhp. And on a straight line for the 6k difference in price just ask jnaut what he spent on his car running 12.2xx on the 1/4 on street tires. Maybe around 4-5k. And on turns the 135 feels good and I think it's a drivers race but they come with skinny little 255s in the real if I recall. My buddy is making 430ish whp with only 3k into the 135 which is awesome so just enjoy the car both cars are almost equal when considering price difference and money invested (performance wise). The 135 is very confy dd tho.

There is pretty much no way this won't beat my Z on a road course. I had R-Comps and sway bars, but I guess we'll see.

It's not a true sports car, that's not why I bought it. The lowest boost setting brings it to 360 rwhp, and I can add another 3 psi or so on top of that. It's not a drivers race against anybody that isn't Jnaut...I have no trouble turning out sub 5 second 0-60 times starting in 2nd gear, and 0-100 is right around 10 or less. The Z was lucky to do that in high 11's.

Bottom line is you guys are frustrating me...I am still a loyal Z enthusiast, but I'm just pointing out how disappointing it is that Nissan put such an un-tunable motor into the 370. The car would be awesome if you could pump out 400 rwhp for under a grand. Unfortunately, you can't, and as a result...the 135i has been a much more "fun" alternative to my Z.

Untunable motor?! Are you serious! First off VVEL hasnt even been cracked, there are so many parameters that havent even been touched. Right now its just AF ratio, timming and a few other little adjustments...and even for what it is, it still makes decent power on a tune. Second, you need to realize that your "just a tune" is for your TURBOS! You have what 300hp/300tq TWIN TURBO charged straight 6 right? Well of course a tune is gonna do allot for for you, you have (2) huge power adders right there. That straight 6 motor with out the AID of turbos wouldnt tune for than 10-15rwhp. NA gain VS FI gain is a retarded comparison. In fact i dont know any motor in the history of man (maybe you can enlighten) that is NA with "just a tune" that picks up over 150rwhp. Your tuning for the TURBOS not the motor...that motor is nothing more power than a Scion TC without the turbos. Third, about the handling, you say that with just sways and this and that you can keep up with a 370Z..? Am sure, maybe, but what 370Z is gonna stay stock anyway?! Stock for stock, mod for mod the 135I will not outhandle the Z.../

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.

I don't know a single person with an aggressive tune on their 335i or 135i that hasn't blown a turbo or had to get the fuel pump replaced as a result. Only the guys who opt for the milder ECU tunes (30-40WHP) are able to maintain stock-like reliability. The guys who go all out for the 80-90WHP JB3 and etc. don't.

ianthegreat

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.

I don't think we're intending to frustrate you bro. Everyones entitled to their opinion. In terms of "un-tunable" I think it really depends on personal preference and the "want" for power. It's hard to compare an OEM NA car with one that is F.I. Any F.I. car will make more power per mod. Once the VVEL is tuned I think the Z will be able to make even more power, both NA and with those who choose to go the F.I. route. But other than Porsche (and BMW wit the E46 M3) I don't see many other cars with so much power out of the box from a 6-cyl engine. Also, the Z has been shown to make 40 whp gains with intake, exhaust, and "tune" (just to smooth out AFR). I have a very long daily commute to work, and even on the freeways I dont have much chance to open the car up. I don't have much use for anything faster than this, even though I will be doing some bolt-on mods.

It all comes down to personal preference. I don't think anyone's "hating" on the 135i. Different strokes for different folks.

Some of these numbers seem amiss. The "lowest" boost setting makes 360 whp? It's rated at 300 bhp, so I'm thinking 260 whp stock? So you're saying that just by turning up the boost you're gaining 100 whp? I doubt this, but if so, what is the stock boost? And what boost is the "high" setting? If you're gaining 100 whp that has to be a difference of almost 50% boost or more, which in every other stock turbo car I've seen, would need bigger injectors, fuel pump, oil cooler, and FMIC to operate without heat soak, knock (there must be a timing advance in this tune - there's no way it's just from increased boost), etc

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.
