Маховици (Flywheels)

Post by martin7937 » Mon Feb 24, 2014 11:51 am

Някой с Nissan Fast - искам да засека разпосочни данни от информация, които получавам напоследък.
Баща ми премери заводският маховик на моят автомобил и кантара показа завидните 8.30 кг. Ще го помоля и да ми даде парт номера му, надявам се, че ще успее да го намери.
Молбата ми е някой да ми даде инфо от фаста, срещу SJNBCAP10U0901112 какво излиза като парт номер.
В същото време двама души ми предлагат маховик от Р11, но ако не се лъжа SR20De, които са отново по 8.20 - 8.40 кг., т.е. грам не минават за ъпгрейд под каквато и да е форма, независимо информацията за теглото посочена в http://nissan4u.com/parts/primera/el_p1 ... tration_2/" onclick="window.open(this.href);return false;
И все пак познавам лично човек, чиято кола съм шофирал и който е с Р11 маховик, който бил по-лек от неговия, но не е мерил килограми...

Искам парт номер на заводския маховик по написания вин по-горе, за да го засека.

Много искам някой с Р11 GT да ми даде инфо за теглото на маховика си, ако го е теглил или ако предстои да сваля кутия, за да го претегли.

Нямам достъп до UK форума, там може и да има. Въобще - дайте някакво инфо, с което разполагате.
Нищо свързано с щатските форуми не ми върши абсолютно никаква работа, там всичко се върти около USDM и JDM SR20, които нямат много общо с нашите.

Тенкю :)

Хайде бре, няма ли някакви предложения/мисли? Излишни маховици тук-там, които да премерим?

All P11 SR20 shares same PN for flywheels. I have P10, N14 and P11 flywheels in my garage. I will weight them when I get there.

P11 one is two-piece and feels ligher but only weighting them can prove it.

Ok, good to know there is someone who has different types and can weight them. Please also share the PN for each piece.
I don't know if you were able to translate the above, but it happened that I found out that my stock flywheel weights only about 8.3 kg. Last night we had this conversation with skydiver about the benefit from switching to P11 flywheel. The one he has is from the P11-144 which is about 7.5 kg but I am not quite sure it fits the P10. It should, but not sure if anyone ever did such swap, plus if it is only about 0.7 kg... I wouldn't bother.
And yes, I am considering replacing my Fidanza because I am not sure it works fine. I have to take the gearbox down and see if it has worn surface (which I hope is not the case). It is most likely to be the clutch leaving the slippery feeling I have above 6000 rpm, but I have to check it first. If it is the Fidanza, than.. I will downgrade to a stock flywheel since the price to pay for rebuilding the Fidanza is quite high, plus the time spent for arguing with stupid customs...
Thanks!

Well, some update here..., about the P11-144 SR20DE flywheel's weight :
8,346 kg (only the flywheel)
8,788 kg (flywheel + sleeve)
8,978 kg (flywheel+ sleeve + bolts)
Excuses for missleading you, Marto...
I'll measure the SR16VE flywheel this weekend and will update you.

It would be great if you could updated your post with the PN of the P11-144 flywheel, thanks.
Great to hear I still have the lightest (stock) one :)

I think Fidanza can be easily resurfaced if you have problem with heat marks. But you should check first as you mentioned...

SR16VE is supposed to be lighter, so if you have one, please weight it. :) Good info too: http://www.sr20-forum.com/driveline-tec ... heels.html" onclick="window.open(this.href);return false;

PS: On my current N14 Track SR20VE build, im simply using OEM flywheel...

I think I even have a better link at home (source of info regarding flywheels). I kind of started reading it the other day and I found it more explanatory. Will share it later.

Anyway, check this out (last page from the above thread):
N15 - 12310-1N500 - SR16VE - FWD - 7,690 - 09/1997~10/1999
N15 - 12310-1N501 - SR16VE - FWD - 8,750 - 10/1999~End
N15 - 12310-3J200 - SR18DE - FWD - 9,600 - 05/1996~09/1997 (5HB)
N15 - 12310-62J02 - SR18DE - FWD - 8,436 - 01/1995~09/1997 (4S+3HB)
N15 - 12310-WA000 - SR18DE - FWD - 9,600 - 09/1997~10/1999
N15 - 12310-WA000 - SR18DE - FWD - 9,600 - 10/1999~End

Weights are in kg, i.e. my stock flywheel is still lighter, with only about 0.1 kg but still..

Seems like my theory from nissan4u.com flywheel weights was right (RR flywheel lighter than highport/lowports). This is what I have weighted today...

Clutch side

Engine side (sorry for blurry picture)

P11 flywheel is two-piece, can be taken apart easily. Design is good and lightening will be easier than older style.

I don't understand what you are saying.
What we have are 7 flywheels. All of them, except the first one on the top left side, weight pretty much the same.
You name them "LIGHTENED". Mine is 8.2-8.3 stock. Why should I consider it lightened?
And what makes the P11 flywheel better than the P10 one - because it is from 2 pieces? What is good about that?
Sorry, I just don't follow you..

Top left is stock. Three flywheels next to it are milled. You can clearly see this from back side (second picture).

But thinking about it and checking nissan4u again, top left is probably P10 85/92kW (listed as 10.7kg) and other ones should be from Sunny GTi 105kW (listed as 10kg) and P10 GT is listed as 9.2kg (i didnt ever had any of them).

P11 - lighter in stock + easier for milling them. Should be around 7kg then...

But mine is 8.3 kg stock and I never did anything to it. I was even the first to remove the gearbox on my car in order to change the stock LuK clutch.
So basically, there is no lighter than 8 kg stock flywheel on any Nissan model.
If I am following you, the only way you can go below 8 kg is by modifying any stock flywheel.
