...for a 16xe engine.
iv been wondering about this for some time now and heard a lot of mixed reviews and storeys on the idea.
its easy to get it lightened but finding somewhere that will balance it for a sensible price is seeming quite difficult to find.
iv been told off a few people a 1.6 8v flywheel and clutch is a cheaper and easier way around it, as is the x14xe fly and clutch...
but iv also heard any form of lightened flywheel makes it idle rough
anyone care to expand on this for me please?
cheers 
p.s move to help zone if you think its for there, i wasn't too sure

Ive had one for my c20xe for ages but stories have made me not fit it ive been told
That it throws the crank out and could put a rod threw the block
It cuts out when slowing down as it cant keep the mass
Rough idle
loads of stories really but ive heard good aswell so i would like to know aswell

Got one on my xe. Made throttle response a bit quicker in the rev range. Other than that??
Worth doing if the engine is apart and striped and can do the other neccessary changes. If not and you have it in the car ect it's not worth the hassel tbh
IMO that is..

Hi Jed, I had one made for my last 16xe engine and it weighed roughly 2kgs and what a difference it made, blip the throttle and the revs would shoot up.
Mine didn't tick over too roughly and never stalled anywhere.
You do have less engine braking when you come off the throttle so expect to brake a bit harder when slowing down lol
Have you seen the standard flywheel its massive and weighs a ton.
Even fitting the 8v flat flywheel will make a difference in acceleration.

i too am also thinking about doin this to my x16xe that im building, whats actually needed to do it? literally just the flywheel or the clutch aswell? thinkin of using an x14xe flywheel

when you say you had one made, how much did it set you back f you dont mind me asking, and did you get the full monty (crank balanced etc...)
i think its the next steps for my engine like

It cost me £170 made from billet steel, the main part of the flywheel was the same thickness as the ring gear lol
It came pre balanced matey, it was from a lad on Migweb.
I didn't have the crank, rods and pistons balanced as the engine has already been blue printed.
If your going to have it all balanced there is a good bit of weight saving in the crank if the budget allows.

Correct me if I'm wrong but iirc the 14xe clutches are smaller in diameter than the 16xe's.
So you would need to use 14xe flywheel and clutch.
How heavy is the 14xe flywheel? Is that not a pot type one like the 16xe?
If it is I wouldn't bother I'd go for 1600 8v flywheel if your on a budget.
I've even had an 8v flywheel lightened and I thought it would come back with a noticeable amount removed, but nope it was maybe a few grams lighter!!!!

im not really looking to spend big bucks tbh, cheaper the better, without killing my engine obviously. if theres a high chance il throw a rod or something il not bother.
also, i think theres both a pot and flat type flywheel for the 14xe
how exactly are they lightened anyway? i have access to a lathe if that whats used?

Every engine is balanced as standard, so aslong as you get your new devoloped flywheel balanced it shouldn't cause you any bother.
On the 8v flywheel I had they machined the square lip off the outside, put an angle onit if you know what I mean.
Hardly worth the £100 I had to pay them for doing it!!
Are you after more acceleration or more top speed?

Removing rotational mass from any part of the car is far superior than reducing static mass and especially a flywheel in particular. The further away a mass is from the centre of rotation, the more torque and power is required rotate it. Reducing this mass mean less torque and power is needed to rotate that particular part and means more available torque and power will be seen at the wheels.
Fitting light weight wheels is another great way to reduce rotating mass and free up some ponies too

I'd have to disagree with the above comment about the 8v.
As standard the 8v will be quicker because the 16v standard is quite sluggish till it gets the revs up, but you put a very light fly wheel on them and to many revs on set of will light the wheels and when it does grip it will be bye bye 8v lol
Best thing and one of the more cheaper mods was to put an f13 cr box on mine with a 4.5 cwp, I was in 5th gear in a flash, downside was it only had a top speed of 108 ish miles an hour but getting there was fun ;-)

fit an 8v flywheel for a cheap mod.
My last c20let I had one from a lad on migweb for about £170ish iirc. Does make them rev a lot free er(not a real word but it will do)

So if the flywheels balanced all should be good then? Because everything else is balanced before hand? Is that right
thanks

well i had a x16xe in my corsa and a friend had a c16se 8v in his car and his car was a lot quicker and pulled alot harder. imo x14xe/x16xe are just loud so makes people think there better
but c16se roar is better than any small engine ive heard

Had one on my XE.
Never drove it with a standard one so can't comment on the difference but it used to drive well and had no adverse effects.
