Flywheel

Mornin all,

Sounds like you all had a great Saturday! So pissed! I was workin!

Anyway, do any of you know if there is any light aftermarket flywheels available for the S13 in South Africa.

Nope... and why? Some people lighten the fly-wheel by skimming and other tricks performed by engineers... I don't believe in it, robs you of torque.

Dont want to go the skimming way, too dangerous. know its less, but throttle response is insane, also if your car is modded enough you wont even feel the change in torque.

Nah sorry don't know any local oukes, Import... Import... Import 😂

money money money!! 😂

There are Alu Flywheels but they are full imports and very expencive

Also there is a way to get a nice Flywheel for cheap.
The CA18DET motor can be modified to fit a SR20 flywheel, this will allow the use of the much cheaper SR20 Flywheel kits.

But we have to use a special starter then

THat still sounds expensive!! Well guess the import thing will have to happen, but not now! much much later.

If it was availeble here local at good price I would have bought one now. 😈

No it doesnt, its a common misconception, its not altering your combustion chambers so your "bang" remains the same, no change in torque.

What it does do is rob you of inertia, a flywheel is basically a gyroscopic dynamo (or "mechanical battery" if you'd like) More mass = more stored energy, less mass = less stored energy, basically means a lighter flyweel will absorb (rev up) and loose (uphill driving etc) energy alot quicker...

In my personal opinion the CA's flywheel is friggin heavy (heavier than my 325i flywheel) so it can shed a bit of weight, just dont go nuts and make it look like swiss cheeze, we will all laugh at you when it shatters at 7000rpm and cuts you off at the knees, stumpy 😛

I think its sumthing like 10 kilo?? Correct me if I'm wrong here!

well my crank is lighter then my flywheel honestly.

That thing is damn heavy

Well I have skimmed my fly wheel and the only problem I have is a slightly lumpy idle, not enough weight to sustain the motor between strokes.

yeah that is to be expected.

How was the difference from the stock flywheel?

It revs ALOT quicker now.

Hmm never picked up a Single lump Idle...

And My cams are alot more aggressive.. Its smoother but does feel slower to me in all honesty

the stock flywheel is 13kg's!

i weighed mine.

then i took it to the engineer to remove "meat".

he did his best, but said that taking off more than 3kg's would make things very dangerous.

i didnt want a life threatening flywheel - so i paid and smiled at my 10kg flywheel!!!

i'm short enough, i dont need to be shorter! 😂 😂 😂

Hi Veecee, what has the effect been on the reduction of weight on your lightened flywheel? who did the work and was it balanced after lightening? Lightening my flywheel has been on the cards for some time but not sure of how much to have taken off.

hey antman...

my engine was rebuilt by JB Engineering in strijdom park...

as for it feeling different - i must say i cant really feel any difference on my butt dyno. i've driven many many s13's that havent had this mod done, and i've driven mine. but its a little difficult to know for sure, because i never really felt MY engine/car before the rebuild was done.

my car does rev happily to the redline though, no problems.

after my engineer was done with the motor, but before he assembled it, i had it sent to edenvale for balancing and blueprinting. so its really smooth. that was a really good thing to do, and its quite cheap. less than a grand to balance a 4 cylinder, its worth every penny.

i would say if you're strapped for cash, rather have the engine balanced than reduce the weight of the flywheel!
