Spec Clutch (2.5L)

[QR25DE]

Hey all, it's about that time to replace the clutch on my car. Beating it and the amount that I drive my car it's starting to slip (this morning was horrible lol).

Has anyone upgraded their clutch in the 2.5L? http://www.specclutch.com/cars/Nissan/A ... 009/Single

If so, which one did you go with?

Thanks,

Scott

From Spec Clutch Customer Support: I emailed them with basic info about my car and what I was looking for...

Scott,

I would look at stage 2+ and 3+. They offer plenty of torque capacity and the drivability you are seeking. They also wear well, the 3+ having the best wear life of any clutch money can buy. I would caution you about one thing, however.. if you do not replace your original flywheel with another or go to one of our billet flywheels, you may have some performance and wear issues. The original flywheels dish badly with use and offer a bad surface to which the clutch disc mates. So I would save up and do it all at once. The mileage of your car makes it a no-brainer. The original flywheel is a 2pc dual mass unit, which is not resurface-able.

Regards,

David


This is excellent information and customer support. Literally within 30 minutes they replied to me. Crazy. Recommended.

They have a flywheel for our car,I havent checked their site in a while but if they have a LW flywheel It'd be awesome. If they dont I want to see if us 2.5ers can generate enough interest for them to make one.... I think they said they need 15-20 ppl

edit: checked them out and saw they do, wonder how much it weighs lol.

[QR25DE]

Sent back an email and the link for the thread to them. *Waits*

[dldjros69]

[dldjros69]

Oh and how many miles is your coupe? Kms dont make sense to me lol

[QR25DE]

Check the link in the OP for the prices...

83 000 kilometers = 51573.809 miles

^^ google is a wonderful thing...

[wade001]

I dont need one but would buy it anyway because i race my car. LW flywheel/ stage3 clutch/ HLSD? I think so lol !

Yeah same. If I was going to do it, I'd do everything at once. The problem is money.. :/

I know what u mean, I've been holding back since i got the car so I can try to do this. I mainly drag race, probably going to get the stuff but install after I've perfected the 1/4 mile stock. with those things and light weight wheels im hoping low-mid 14's at least. I have all the resources to do the job here at my college so I dont have to worry about having someone do it for me. but I plan to have this done for next spring at the latest hopefully. I want to show a N/A 2.5 can go fast, hard yes but worth it.

How many miles do you have and how much does this cost ?

[dldjros69]

I asked the same question 4 posts up!

Click on the link in the first post, omg here: http://www.specclutch.com/cars/Nissan/A ... 009/Single

And David e-mailed me back:

Scott,

The original weighs 24lbs, the billet 10.2 lbs, a 13.8 lb reduction. David


That's a crazy weight savings. This would make the car drive completely different, fast revving for sure. Damn I so want to pull the trigger on this but no cash lol.

[dldjros69]

All all about this for sure. Gotta buy the gf a ring first before i spend any $$$.

Pros-faster reving, more whp?
Cons-?

[QR25DE]

How is a clutch going to give you more whp? I literally give up. I'm done.

[wade001]

clutch wont give more HP, neither will a LW flywheel. but what it does do is reduce drivetrain loss.
less drivetrain loss= more HP free'd up to the wheels
I'm all about that lol
I'm trying to make my car efficient, so when i build it it will be CRAZY lol.
downside to a LW flywheel is getting the car going, it'll be more sensitive because of less energy. but, city driving MPG will improve/etc. benefits are awesome !

[dldjros69]

Getting it going? Like off the line? Thats what i was thinking less dt loss more whp.

Hey flamer im trying to learn here. Im not as knowledgeable as your snooty @ss. You could try and be more helpful!

You need to start relying on yourself and not others to guide you through life as well. Money isn't the answer to everything and I would suggest thinking before asking a question. Most of your questions can be answered by yourself if you think about how it works or do a quick Google search to educate yourself.

I do not see how you have boosted your car and not know anything about what you have. It's a shame really.


Back on topic, I think this would be a great upgrade for any 2.5L. They make 3.5L clutches as well. I just wonder why no one else is starting to support this motor 2007+, it kinda blows. Ah well.

*Saves pennies*. Wish I would have waited and did turbo + clutch + flywheel + HLSD all at once. Would have been so worth it. haha.

[wade001]

exactly, when you are not initially moving the flywheel is still moving, having an initial momentum(energy), it takes more energy to stop more rotating mass. thus making it easier to start moving as there is more energy. this is a big factor in getting moving because you have to get the car moving, easier to stall with a LW flywheel so you will have to adjust for the difference. and 13lbs lighter is HUGE. im going to keep it a secrete as to how much though lol . but if you read up on it online you can figure it out.

Ok so overall this will cost us about $1,500 with install im guessing ? Now my ? is is this really worth it? Like i mean its alot of $ but its worth it if you need to replace your clutch anyway right?

[wade001]

depends on what you want to do, for 1.5k you can do a lot. if you have to do it anyway I'd say it makes sense.

[QR25DE]

If you're clutch is starting to slip or is getting weak it would be worth it. It's more worth it if you are making a lot more power (boosted). But for a stock motor with bolt ons you are fine with the OEM clutch and flywheel.

There are benefits to having it in conjunction with the stock motor but not as much. You would still certainly see the difference.

Werd im in class so i cant see the video but the info was deff great. I personally am not good with all the car talk. Yes ive been on here forever at this point but i am still a newb when it comes to overall performance issues. But i am trying to learn because i want to end up turboing my car, and i want to know what everything is that im doing. Appreciate the help though since all you guys know 10x more than me

Love you matt! (no h0m0)

<3 u too bro just lookin out for my peoples i know everyone gets edgy but come on were all friends in the end especially those of us that have been here for a while

[RandyFool]

Sooo where exactly does this clutch go on a cvt?...jk. I guess i need to save so i can drop a mt in there, and then clutch and turbo. Hey if you can get your best e/t on the strip stock and put it side to side with the new clutch and flywheel if you go that route I'm really curious how much the diff will be. I foresee a bump in the future.......
