I've been looking to upgrade my clutch and flywheel for some time now. After reading almost all of the threads pertaining to clutch and flywheel upgrades, I've noticed that no one seems to mention what the kits come with. I've decided on the TRD clutch; can anyone tell me whether or not it comes with new bolts, throwout bearing and such?

Can't seem to remember where but someone in another thread mentioned using a new flywheel bolt as reusing the old one on a new flywheel is not recommended due to it being weaker. Can anyone comment on this? Oh, the flywheel I'm looking at is the Fidanaza one.

 

flywheel weight reduction is too much compared to stock... imo ..


the trd kit comes with a new throw out. bolts? new bolts for what ?


the trd kit is just an upgraded pressure plate but with a stock disc..... I DO NOT RECCOMMEND IT

if you want new flywheel bolts they just have to be grade 8. like 6-10 bucks worth of bolts at a hardware store. or 10-13 dollars worth at a dealer.

 

thanks for the reply Hotbox. So you suggest another brand clutch and just keep the stock flywheel?

If I install a new clutch, does that mean it is recommended to resurface the OEM flywheel as well?

I've always been curious as how a lighten flywheel would feel like. Some of my buddies have upgraded their clutches on their cars, but none of them has even touched the flywheel. Another thing, is it crazy to upgrade the flywheel but keep the clutch stock?

 

flywheel will need to be resurfaced.

a lightened flywheel will give you a few hp and let yer motor rev quicker , but it also means that when just put putting around town you will have to rev match each and every shift cause as soon as you depress teh clutch that flywheel is gonna slow down super fast.


yes it is crazy to keep the clutch stock no matter upgraded flywheel or not, lol . it just cannot hold...

what I should have done was had my flywheel lightened aka back cut. lose a few pounds but not almost all of teh weight liek a jun or a fidanza. but I didn't have teh time so it just got resurfaced.

i'd go with act clutches , spec , or clutchmasters. I have a spec stage 2+

 

Thanks for the replies hotbox, I know some of my questions may sound stupid. I'm just glad you're willing to answer them.

So resurfacing a flywheel is just like the way they resurface a brake rotor? When you mention back cutting a flywheel, is this procedure something that any mechanic can do? The place where I'm planning to go to get this install is not a performance shop or anything.

So with all the brands you've suggested, you think Stage 1 would be alright? I've got some bolt ons, but I'm not planning to go FI.

 

resurfacing is exactly like a brake rotor except it is balanced.

back cutting is where they machine the back excess metal that isn't needed for much.

this all gets done at a machine shop.

any mechanic can install it all. but the resurfacing and back cutting/lightening happens at a machine shop they do heads , blocks , rotors , drums , flywheels. all that jazz.

stage one should work well for you.

no problem man.

 

Gotta ask. In referring to the clutch. You talking pressure plate and clutch disk? I'm thinking the stock PP doesn't have strong enough springs to help the disk live a normal life.

 

the oine and only reason the clutches go out on xB's the way they do is that the clutch kit stock is meant for the echo , 200 or so pounds lighter , less aggressive gear ratios , and less likely to have power adders.


the trd kit uses stock equip disc and upgraded pp.

I would hope he's talking clutch kit as I certainly have been , lol.

 

Cool, that's what I thought but you never really know on here. lol

 

true that, lol

 

We just got some new clutches from LuK and have them listed on our site. These clutches are designed for our Scions, for racing our heavy duty everyday use! Heavy duty for those lead footers! :D Check it out here: http://www.precisionmuffler.com/id143.htm

 

i'm pretty sure some xa owners have had the same issue.

 

true but less people upgrade xa's so you don't hear about it as much. but yes. sorry i left ya guys out .

the xa's do weigh slightly less tho. not by much tho. both xa/xb are somewhat significantly heavier than echo's.

 

clutch masters stage 1 is a comfortable upgrade once the clutch finally goes IMO. ill need it soon. this is the last winter on this clutch.

 

Is the average lifespan of the stock clutches around 30K? This seems to be what I've been hearing. Too bad they weren't a little stronger so average people could get 100K out of them.

 

I have had mine on for about 65K miles and I have been on many road trips. I also have a lead foot, it was than I decided to change my clutch. :D To something heavy duty, LuK

 

My car just turned 60 on thursday (sniff sniff) i think next winter is gonna be the last winter

only when the clutch is real cold, below 40degrees ambient it slips at 1/4 to 1/2 throttle, then the fun begins climing up hill :-/ im glad i only drive 1.3 miles to work

 

if the car is stockish at least 60. if the car is bone stock and grandpa driven about 100k.

if modded and driven hard 5k starts slipping 30k slips horribly

 

I would only use flywheel bolts from the dealer. NEVER reuse your old flywheel bolts. Ive seen many flywheels come off from people doing this with Toyotas.

hotbox- how do you like that spec stage 2?

 

Anybody know exactly how to get these flywheel bolts from the dealer? Is there a part number or anything like that? I can imagine the confused look on the guys that work in the service dept. if I were to just ask about buying flywheel bolts....
