like the title says, im doing a s4 13bt motor swap into a gsl-se shell that has a gsl-se tranny. this motor will *NOT* be turbo'd to begin with due to financial status, so im going to use all of the N/A parts to begin with. im not worried about the tranny not being able to withstand power right now, cuz it wont have very much power, cuz it wont be turbo'd.

THAT BEING SAID, what flywheel do i need to use with a gsl-se transmission???

 

S4 TII engine
S4 TII rear counterweight
GSL-SE light flywheel (steel or aluminum,any brand)
GSL-SE clutch
GSL-SE tranny

Not the cheapest way,but its the easiest and its a performance upgrade thats well worth the cost.

 

On flywheel any aftermarket 225mm one will do as long as the correct counter weight is used for the motor.
Also with the clutch, any 225mm clutch will work.
Just referencing that it does not have to be for GSLSE.

 

so i cant use a stock gsl-se flywheel???

and i thought the counterweight was part of the flywheel?

 

Yes ,you can use a stock SE flywheel

 

This wasn't hashed to death repeatedly in your OTHER thread?

What, you want everyone and their brother to tell you all over again with more *feeling*?

 

No, you cannot. If you don't know, don't say nothin'.

 

werd

DO NOT USE THE -SE Flywheel..
it doesn't balance anywhere close to the TII engine.

going the auto weight/lightweight wheel would be optimal.

if you are 100% sure your TII engine is an S4, you can use an S4 N/A flywheel.

luckily for us all engine series (S3,4,5,6) turbo/N/A balance the same.

 

ok...thx all for the info...and peejay...i wasnt totally clear with what everyone was saying, which is why i made another thread for this to be %110 percent clear. cuz i need to have everything ordered up and this project going underway in like a week.

im gonna use my s4 13bt engine with a s4 flywheel and gsl-se tranny.

 

It really depends on what you have laying around.
If you have the s4 flywheel use it.

The key to this would be to use the S4 counterweight.

I have a S4 motor, gsl-se front cover, gsl-se oil pan, S4 uim/lim, and the S4 tb with the tb mod done, No emissions, GSL-SE AFM, S4 lightweight flywheel, S4 counter weight, Centerforce stage 1 clutch, and the GSL-SE tranny.
Go to my VB garage or my cardomain web site to see the pic of the motor.

 

I don't think he is using a TII motor. I think it is a NA S4 that he wants to turbo later down the road.

 

As stated before, this is info that has been given to me by several Rotary mechanics. So yes your right , "I don't know" but I guess all the other first gens running around with this setup "don't know either".

With that said, I will bow out as I hate trying to justify any info that I was trying to share. I would HIGHLY recommend that the individual that must have the CORRECT answer contact a Rotary shop/mechanic so that they can have PIECE OF MIND with their decision and NOT go solely by this forum.

 

ugh...see peejay...this is why i get confused...

I AM USING A S4 T2 MOTOR WITH A GSL-SE TRANNY!!! (i want the t2 motor for the low compression rotors so it will handle boost better when i DO turbo it)

so what flywheel do i use? will the s4 one still work or do i need a gsl-se one or what?

 

Oh there a lot of things that so called "rotary experts" will say you should do.

Like putting a Purolator fuel pressure regulator (proven to restrict flow even for 50hp applications such as VW Beetles) inline on a stock carby 12A. Stock right down the the fuel pump, which can barely keep up.

mazdaverx7 (think I got that right) had the wrong imbalance flywheel on one of his engines. Something an FPO did. Aw man you shoulda seen the inside of his engine. Bearigns were hammered, one was *siezed*, and the rotors had been smacking the side housings from shaft flex.

But technically yes it did bolt up and he was able to drive it... for a little while!

 

Yes. There needs to be a way to kill people online. Some people live to disseminate misinformation. They're the same ******** who don't use turn signals and do other blatantly inconsiderate things.

The only trouble with killing people just because they are ********, is that it's so hard to tell when to stop.

All S4 engines have the same rotor weight. N/A and TII. The imbalance is therefore the same. The flywheels therefore can be swapped between a S4 N/A and a S4 TII for the purposes of mating up a given style of transmission.

The same goes for Series 5/Cosmo/FD engines - they all have the same rotor weight, and therefore the same imbalance, therefore the flywheels are interchangeable.

Simple. There are no ifs ands or buts about it, and you can only swap flywheels cross-generationally IF IF *IIIFF* you disassemble the engine and have the whole assembly re-balanced in order to get the flywheel imbalance correct again.

But I have a feeling you do not want to do that, you just want to slam the engine in and get your junk on the road, so you just want a bolt-on solution instead of getting fancy and spending a lot of money on rebalancing even though it'd be cheaper to buy an aluminum flywheel setup when all is said and done IF you were to take that route.

 

as peejay re-iterated above...

it doesn't matter

S4 is S4, N/A or TII...

 

Hate to throw a wrench into this,but will his SE trans with an SE starter properly engage that S4 N/A flywheel's ring gear?.............

 

Yes,

ALL 74-91 N/A Starters are interchangible (not the same, there are a couple slight differences)
the rule of thumb is:

If a stock Flywheel is being used, use one from the same "series" as the engines rotating assembly.

If using an N/A (215 0r 225mm) flywheel (stock or aftermarket), use the N/A trans case, and matching starter.

if you are using the TII trans/bellhousing etc.. you must use the TII starter and the 240mm stock flywheel from the same series... or an aftermarket flywheel using the rear counterweight from the same series as the rotating assembly being used
