YouTube - Nissan 370Z vs. BMW 135i, Mazda RX-8 R3, and Pontiac Solstice GXP - Car and Driver
370Z beats the 135i stock vs stock and is $4000 cheaper. The straight line accel is identical and the 135i has more low end torque (duh) but the 370Z is the clear winner in this comparison. Also, I've been doing some reading and if you just do an ECU tune and turn up the boost on the 135i it wont perform nearly as well or as reliably as if you added supporting mods like FMIC, exhaust, fuel pump, etc, which will bring the modding cost over $2k. So, yes, a bolt on 135i with tune will make close to 400 whp, but that's total about $6 grand more than a stock Z. The point? If you make the cars equal in price, that is invest $6 grand into a stock Z just for power (SC or TT), the Z will still make more power and have the superior handling if left stock in that dept. They're both great cars for sure, but in independent testing, the Z wins and comes in a lot ($4000 to me is a lot of money) cheaper than the 135i. HOWEVER, if all you want is performance at a price, you'd be better off with a 5.0 Mustang GT. So performance on a track and in a straight line is surely not the only criterion for selecting the car for you.

For the record, I meant the 135i would leave the 370z in the dust... acceleration wise. The 370z outshines the 135i in the curves... And yeah, a '11 Mustang GT would be far better bang for the buck than either of these two cars.. or *gasp* a c5z06.

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.

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.

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. |

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

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.

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. |
