Well by all means the Tilton is better performance wise. I had first switched out to a Tilton flywheel/clutch set up but ended up changing it to a JWT setup though. Tilton made the car a monster. It was awesome when it came to response and the RPM's would jump to the roof. It will put a smile on your face. The problem with the Tilton setup to me was that it has be driven way, way, way to agressively. Also it will make loud squealing noises until you become a master at it and the chatter is 10 times worst then any other lightened flywheel. The chatter wasnt an issue to me but the squeal coming out of every red light was embarassing. Now keep in mind that there are people who are extremely good at driving these types of setups and may enjoy it with out the noises and all. I would suggest you try to go for a ride or test drive someones car with this set up if you decide goingTilton.

JWT is super streetable........almost like stock. The performance is better than stock as well, Im happy with it.

jm, which version of the Tilton clutch did you have? Semi-street or full-street? If full-street, could you please explain how it had to be driven as opposed to the JWT setup?

+1. I had the Semi-Street. The full street only gives you a little more slip for daily driving.

From that the tilton seems better performance wise and ill notice where my money went. when on the other hand the JWT is more mellow but still not that big of a difference over stock. Correct?

I would say that yes there would be a difference but I would suggest you try to find these 2 setups around your area and give them a try it would help make the right decision.

I have had both tiltons set ups. The semi street is a blast but its really touchy and u cant really let it slip it or you will stall. Each shift is intense and you feel torque hit as you u shift. once you get hang of semi street the performance is great i compare to driving a bike because shifting and reving is very fast. If your car is daily driver and u have passengers u are better off with The full street version its toned down a bit but still offers great performance. It also allows you to slip clutch therefore its alot easier to drive. I would recommend the full street if you plan to go na since it only holds 300 whp. BTW the chattering you hear from 8lb flywheel sounds like a cement mixer and you get use to it because of performance. Best thing to do as someone stated is to find someone in your area and go for a ride..good luck. Im gonna miss my tilton once i go FI.

raising your idle will get rid of the cement mixer sound

my idle with the tilton street clutch is around 1300rpm

Sentry65,
Which version of the Tilton do you have? And has your MPG increased or decreased after installing the flywheel? Thx.

Well, i want to haul *** and if i have to deal with some things to do it. im ok with that. Is it like night and day between the semi street and full street? If it is then im going semi all the way! it is my daily driver but when it comes to cars i dont mine having to deal with things. My past cars have been full hydraulic show cars. If the reward of dealing with **** is a smile on my face then im happy, andit sounds like the acceleration is awesome! Thanks for replies

i have the full street version. Here's my summarization of it:



- mpg goes down

- you will tend to drive the car above 2500rpm almost 100% of the time to avoid the chattering vibration shuttering sound

- your car will sound like it's broken. People will come up to you and ask you if something on your engine or transmission is broken, or if you need a new throw out bearing, or if something came loose and is rattling around.

- It will squeel a little almost every time you take off from a stop.

- It will shutter and vibrate really loud if you're in too high of a gear or if you're below 2500rpm and in anything other than 1st or maybe 2nd gear.

- You can raise your idle and lose more mph, but at least you won't get the clunking cement mixer sound at stoplights and people looking at you like you have a trashed out car that you broke somehow. Idle raised makes the car sound meaner at a stop and gives you a sort of "auto pilot" similar to how an automatic goes forward when you take your foot off the brake pedal.

- There's rumors that it isn't balanced and could be bad for the engine just like the UR crank pulley and might possibly have an effect on the ECU's ability to know what's going on by trying to correct itself too fast or too slow with rpms to reach the idle rpm when you push the clutch in really fast.

- It is easy to stall, but mainly it's when you're not thinking about driving that you tend to stall the most.

- You'll get frusturated more than you have been before with red lights and cars in front of you driving too slow for the gear you're in. So you'll be downshifting a lot more often instead of just cruising in your current gear like you're used to.

- You'll get really good shifting the car into neutral for almost anytime you need to coast because as soon as you take your foot off the gas pedal, you have about 3 seconds before you get a small buck from the transmission because the flywheel is just starting to lose it's natural momentum and since there's not a 2nd disc to cushion the jerk, you get a sharp buck. So you will shift into neutral a lot.

- You'll learn to feel like you're driving on eggshells in the city.

- You'll dread big slow speed bumps more than you ever have.

- You'll possibly hate making the car go from a stop if you're trying to drive slow or don't want to wait for the car in front of you to be 50 yards ahead of you before taking off because you don't want the cars behind you to honk at you for taking your time. So you try to go slow and either jerk or get some squeeling which is basically wearing out the clutch more. Rush hour is one example that comes to mind.

- You'll learn to REALLY cover the clutch pedal for that fraction of a second reflex time that you'll need to push it in before the car bucks back at you because of how sensitive and picky the clutch is.

- When you decide to go FI, you'll wish you had just spent the extra $400-$600 for an exedy or ATS twin carbon clutch cause you'll have to pay out your nose for one and sell off the tilton cause it won't handle 400whp.

- You'll get used to the occasional minor lugging/jerking the car will give you when having to drive under 2500 like in a parking garage.

- You'll get used to people like your mom asking you why you're driving so aggressivly and fast when you take off from a stoplight even though you're trying to drive as smoothly as humanly possible.

- You'll get used to either stalling or reving to 5000rpm (because it's so light) if you don't manage to get the car on its way from a stop.

- You'll grow used to telling everyone who drives your car to be careful or to not freak out if they stall it or if it makes all those crazy noises - people like mechanics, nissan dealers, valet parking (if you must use valet).

- You'll learn to laugh at yourself for stalling on the bump to the entrance of your driveway because you slowed down almost to a dead stop right where the road meets the sidewalk and now you gotta get over the bump without plowing into the garage.

- You'll have no problem explaining to your friends and family who drive your car why it drives "like crap" and accept that they might not be able to drive your car if the situation ever arised.

- And finally at times it'll make you somewhat feel like what you felt like when you first learned stick. Hoping no one comes up behind you at a red light and hoping you don't stall.






...but yeah it has good performance as far as getting the rpm's up really quick and sounding like a race car when you rev it up.


hope that sums it up

ya, and who was it that said in another thread that it drives "just like stock"??? Apparently, perf nissan is overstocked with the tiltons and is willing to *** just to get rid of them. Shame on them. Thanks for the first honest, thorough review i've seen of the tilton street clutch.

It's not a matter of people not telling the truth about the tilton. Some people just have a nack for the tilton and some do not. When I test drove Jeffs car at Performance Nissan, I did not stall and it was not that bad to drive. After I got mine installed, I had no problem when I picked the car up, but when I got back to Reno, I started stalling. I got better, but I hated the fact that you have to think about shifting and pedal pressure, etc. So I switched to the JWT combo so I could just drive and not think about it.

yeah I can drive the tilton fine when I'm focused on driving, but for daily driving I'm not always 100% focused on my clutch technique - I might be looking at traffic or talking with a passenger or whatever.

I always get this feeling that just when I feel like I think I got it down...I don't. I'll say to my fiancee that I haven't stalled the car in about a month. Then 3 hours later I stall...and stall a 2nd time in a different way 5 minutes later.


But it's not all just a pain in the ***. Some good benefits are:


- You'll become a GREAT manual driver over time. You'll get in any car and feel like it's a piece of cake and it'll feel completely fun because you don't have the stress of feelling like you're on a knife edge with stalling in traffic.

- You'll gain a sense of individuality or skill of some sort because you'll feel like you're the only one who can properly pilot your car.

- You can intimidate people by reving the engine so fast. When I went to my dad's house and showed off my new mods, he was pretty impressed and was thinking I might be faster than his stock C6 corvette. We did a some drag racing on the street from a rolling start and I lost every time. So you get to feel like your bark is worse than your bite in a way.

- it'll make your 1st, 2nd, and 3rd gear dyno higher than 4th, 5th, or of coarse 6th gear. There was about a 7whp more in 3rd gear than 4th, and I know there's way more difference in 2nd and especially 1st.

semi street is harder to drive than full street, but not by much

semi street supposvily holds like 450whp

full street holds around 300whp - some say it'll hold more though

full street allows you a micro window of slipping/error ability

semi street is pretty much an on/off clutch

LMAO. Tell us how you really feel! I think I'd remove the sucker if I felt like that about any mod. In any case I am glad I went with the JWT.
