my 370z vs. my 2007 335 coupe...

Zpil0t6

depends.....adding boost..you need to add fuel...the 335 may need injectors and a walbro and a piggy back fuel management system...stock turbo' efficiency may only be 5psi more... so turbo's may neeed to wbe swapped out.

But a turbo done right....is a deadly combo.

The "sport" modes om both automatics are very different. I think I might not be using the one on the Z right. On the BMW if you move the shifter to the right "manual" mode. I goes into a sport mode where it shifts faster, holds gears longer, and downshifts when decellerating. The Z does none of that. Can anyone help?

I asked a similar question and almost got my head chopped off

7AT Question

I also had 335 and really liked the sport mode. G37 also has this mode - DS. 370z evidently DOES NOT have this. It's either boring auto or exciting manual mode.

at 4-5k elevation it will be tough for the Z to match the 335's acceleration. Race those two less than 1000ft the stock 335 will be history especially at higher speeds.

sbkim

I thought both cars are pretty evenly matched even at normal elevation. I presume both cars will do 5 sec 0-60 (+- 0.3 sec)?

klubbheads

New G37 sedan has the same exact acceleration numbers as the 335... Subtract 200-300lb from the G37 that is about 0.2-0.3 second difference in a 1/4 mile time. As far as the 0-60 goes, the 335 will always have the edge. My 3 takes off like a bat out of hell and the very first 1/4 mile pass i managed to do 2.0 60ft time. It took me 2 years to do 2.1 consistently on my G.

I have a feeling that the 335's power will be boosted up a little more by the manufacturer for 2010 models.


BTW: 350z HR easily matches the 335's acceleration.

sbkim

Cool - good to know that Z will have upper hand against the 335.

Zpil0t6

I don't think thats what he is saying.

i beleive a simple relfash on the 335i and you could easily have 30+ rwhp.
It (the reflash) may eqaute to more than 50 crank Hp..

having a modded turbo car in the recent past. Its hard to explain to NA guys how easily you can make an extra 50 rwhp...so long as there is room in the fuel system to deliver the proper a/f and proper " hacking" of the ecu. programming is the appriopiate word.


Sorry to say the 335i could easily handle 400 rwhp(more actually)..Solidly built bottom end for boost applications ,are always tough cookies.( remeber the Grand National..that was a simplton 3.8 v6 single turbo.)
wether the driveline can hold up is the other question.


Wait the nightmare is just begining:
When that Genesis 2.0T comes out... yeah you may laugh now....but i know shops gearing up for its arrival....we are talking close to 300 rwhp without breaking a sweat or a grand /1200. Not bad for 23,700 MSRP. oh plus the grand 1200 in mods.

Has anyone seen the pic of that engine/bay...easy access. I fear we all have more to worry about a youngin in a lightly moded. Genesis 2.0T. spec R

* yes thats to the rear wheels, not crank hp*

I am speaking about stock vs stock. FI cars will always have advantage when it comes to $$$/hp ratio. Just like 03 cobra vs 03 Z06. Stock Z06 is faster when you start modding those two, cobra just runs away from the vette.

Zpil0t6

this is 2009....... the massive power of the FI is a deterement. It cant hook up

hp alone is not the key ..it balance. i spent 4k on my Na C6 Zo6 and no FI car has beaten it with less money put into it......FI cars are very expensive to get massive hp
and are unreilabe.


( agian i had a recent turbo car that was very fast but i spent alot to make it so.


The Zo6 vs the terminator was a classic example.... cammed heads headers and its light weight made it dollar for dollar a superior car than the KB terminator

You must put in alot of money to make a FI a monster. I am talking 0-60 and 1/4 mile


From a roll your point may be valid. My c6 zo6 has murdered heavily modified FI from a dig.

In the GTO forums FI GTO's losses to NA GTO's in real racing 1/4 mile

Zpil0t6

Look at the Zo6 stock aand the Zr1 stock.....0-60 is almost identical....and it has 120 more hp in the same package.( you have to take the runflats off the z06,using the same tires as the Zr1)

Its all subjective.

But when a Genesis 2.0t is designed for tuners.....thats a different story.

i've read the botom end is capable of holding 450 rwhp.

I wish i waited. the Genesis will give many 370Z owners buyers remorse.
I'm no mechanic but i do own a dyno shop/tuner shop.

klubbheads

As i said this discussion was stock VS stock. I am not sure why you keep bringing up modded vs modded discussion.

20k 1992 civic will rape any new ferrari or a vette in a 1/4 mile. You can make any car as fast as you wish as long as you got enough $$$ to dump in it.... I'll take the 370z over my 335 or the genesis any day of the week. Thank you.

A lot of my friends think im nuts going back to nissan after having the Bimmer over 5 months but that is my car and that is what i enjoy driving. That is why there are chevys, nissans, toyotas, bimmers, benzs all over the road. If one was clearly "better" than the other then the losing manufacturer would not be in business.

... then you see a Genesis coupe for the first time and say "thank god I have a Z".

I'm sorry, but no amount of facias, skirts, spoilers, or wheels can save the Genesis from the ugly stick. We haven't even touched on handling yet, either.

Mental Block

Nice to see another New Mexican on these forums. Good write up!

If you don't mind me asking, what dealership did you buy your Z from?

True enough...but the civic isn't an all around car.....its desgned and built for one purpose.

The modded NA vs the Modded TC ......in the begining basica mods favor the FI vehicle.

But if you address the "balance issue" for instance.

I've a customer with an ALL motor 537 RWHP GTO....heavy car. Not only did he add hp, swapped out to drag springs, gears( nothing crazy) a few suspension tweaks.

We have personally seen him crush....CRUSH s/c GT500 Kr at the track. and ride home
with the car only to change pressure.

HP is a good thing....too little is no good...too much....and you don't have balance.



In regards to the UGLY stick......Hyundia didn't compromise on the spec r so handling will be no issue... even the 3.8 Genesis coupe 'felt better than a G37" if only a tad slower in the slolom.

And Ugly....well they did target the Nissan....and i for one think its a sharp looking vehicle.

Sounds to me that imatation is the best form of flattery. A black Gen with the wing
and its Brembo's 4 pot on EACH corner... is a excellent plateform

This car list for almost 7k less than a base /sport 370Z and will be lighter.
(spec r) Do you have any idea how tastefully modded this car can be at the same price.


Your ugly opinion is fine.Thats your right. But i for one think it looks good and its a Hyundai.....gotta sting just a little. What else can you say about it. The Sonata has proven itself to be reliable , able to take abuse and fairly sporting for a "family sedan"


Your gonna be shocked. Not to say its better than the 370Z but surely lets wait till the spec r is fully tested. You do know about its 3 second power reduction if you tag redline right? thats why the 3.8 Genesis did poorly....as the tach or any tach isn't quite quick enough to keep up with actual engine speed. THREE SECOND power reduction... thats the first thing tuners will tune out, to .5 seconds.

however there is no word on the spec r' s torque managment.......but 7k in mods can fix and improve beyond the 370Z.

I for one wish i waited....at very least to test on them same day
