As mentioned on the subject.

Does it feel a lot different..? from a stop from rolling..

I test drive a 2005 model the other day, and haven't really test drive the earlier model (I rode in it) but Iam just wondering how it is compared in real life.... (beside paper specification).

I am looking to buy one, but I haven't decide which one to go for (276hp vs 300hp)..

Actually its 287(274TQ) Vs 300 Hp(260TQ). There is a test in a best motoring video. The 300HP is quicker around a track by a car length or two.

However those videos are extremely bias, yet still entertaining !

 

I doubt you will be able to tell much difference with 13hp.

 

horespower doens't matter. its the difference in torque. some tests have shown the 300 hp model to have slower 0-60 times. its purely just for marketing. the higer the horsepower number, the more appealing it is.

 

for me the major difference was smoothness

the 300hp is so much smoother at high rpm, and the 7grand redline means u can hold onto gears longer. The 287hp felt rough and coarse and ran out of breathe past 6000rpm, whereas the 300hp just keeps pulling all the way to redline. The 300hp 'felt' faster because of the higher rpm and more peaky nature

 

I heard from friends that the 300hp Z feels little more aggressive, even it has less torque, but I haven't tested it yet myself.

 

I definitely wouldn't spend the extra $7K - $10K or whatever the $ diff. is...Just to have a 13 HP bump....just not worth it to me...especially when you can do MINOR mods to get 13+ HP from the 287 HP model anyway!

 

Well holding gear for a half second longer won't help you much, but what I would like to see is how well well that exhaust cam can help for those who are able to spin past stock redline and reflash. I suspect, those with the 287 will be your better candidates for turbo, but the 300 hp to be some kind of all motor freaks

 

you made a good point..
make me think now ...


but I'll to test drive both version to get a feel of each car...

Every test I have seen has the 300 hp Z slower than the 287hp Z. Most people underestimate the importance of torque.

 

I've had a 287HP Roadster now I have a 300HP Track Z.

From about 2,200-2,600 RPM the car feels slower due to the lower torque.

I haven't gone WOT nor passed 3,800 RPM yet since I'm still breaking it in. However, the engine sounds alot beefier compared to my previous Roadster.

 

It is my understanding that all 06 come standard with 300hp.

 

never driven a 287 but the 35th def. has a lot of higher rpm power lasting all the way til redline

 

Nothing a set of cams wont fix for the 287 model.

 

i have driven both back to back. I myself have a 35th 6mt. MY good friend has an 04 base. With out a doubt they are very different. First of all they sound very different. Still a VQ but different tones. As it was ssaid above the 287 hp engine you can definatley feel that it has more torque up until about 3000rpms when the 300hp engine feels the same. The 287 hp engine also defiantley runs out of steam up top near the redline, where as the 300hp engine keeps pulling like a train all the way to redline. Very noticeable difference between the 2 engines

 

Its not just the power difference. You have to consider the fact that the new Rev Up motor has variable intake/exhaust timing which makes a big difference when youre modding the car. It will respond to mods a lot better than the 287HP engine without the variable timing. Its also nice not having to get the ECM reflashed to have a higher rev limiter. In the lower revs, you cant distinguish the difference between the two engines, they feel the same, but you can definitely feel it up top and in the higher revs, torque doesnt mean squat in the higher RPM's. Nissan did it right by raising the rev limiter and making more power up top, a lot more useable power, especially on the track. The torque curve on the Rev Up motor in opinion is a lot better than the 287HP motor. Heres my dyno with the Rev Up motor with Crawford cats, UR Crank Pulley and JWT Pop Charger.

 

From the BMI video it looks like there isn't really a noticable difference unless you took the two to the track and raced them, but driver skill could easily make up for the difference between the two, IMO.

 

I drove them back-to-back and couldn't tell a huge difference... however this was under test drive conditions and for about 10 minutes each. I will say that the 35th pulls hard all the way to redline and has plenty of torque. I wouldn't get too caught up in the hp/torque ratings. The dyno sheets I've seen don't lie.

 

Hey did you get splash guards on your 35th? I didnt get any on mine, not that it matters cause I like them without it.

 

My friend is an engineer at Nissan, and the changes are CONSIDERABLE!

Beefier Rods, Better Flowing Heads, more agressive and lighter valvetrain (Camshafts, springs) for the increased redline.

For me, the extra $4,500 on my Track Edition was a no brainer for the better motor, lightweight wheels, and Brembo brakes. This motor should be able to take a little more boost as well, thanks to its beefier bottom end!
