I currently have these parts
S4 TII Transmission
S4 TII LSD
S4 TII Stub axles
S4 TII driveshaft

I own a S5 GXL, so what parts do I have left to find?
Just a S4 TII starter right?
I dont understand what flywheel and counterweight I need to get. S5 or S4 TII

 

You are going to need the T2 starter and Slave cylinder as well as a s4 T2 flywheel and clutch...... oh jeez, just search.... here:

The details I'm really looking for is whether having an S5 block makes a difference in the counterweight and flywheel setup...I remember hearing that the way the rotors, flywheel, and counterweights had to be balanced. S5 rotors with s5 flywheels/counterweights. I dunno correct my ignorance please.

 

You will need to retain your s5 N/A counterweight? hold on.....

 

yup, retain the s5 counterweight, the counterweight matches the rotors.

 

Yea but the flywheel needs to match the series of the car?...the series of the tranny is irrelevant right?

 

yes, match the flywheel to the series block. The transmission is irrelevant but you will need a series 4 turbo transmission mount to go along with it (mount matches the series transmission.)

 

Transmission and Clutch match Trans type, Counterweight matches rotating assembly series.

 

I'm confused now...So you are saying I need a S5 TII flywheel with a S4 TII clutch?

 

Doesn't matter what clutch you use as long as it is for YOUR FLYWHEEL TYPE (TII or N/A). If you are using a STOCK flywheel it has the counterweight in it (built in). If you are using an aftermarket flywheel it needs the automatic counterweight from an automatic transmission bolted onto the after market flywheel. IN EITHER CASE, the counterweight needs to come from the same series as your engine. If you are still confused, please do try the search button.

 

Clutch and Flywheel match the TYPE and not the series. As in N/A or TII.

The counterweight matches the engine series. As in S4 or S5.

Make both happy.

TII trans means TII flywheel/clutch, the flywheel series is determined by your engine.

N/A trans means N/A flywheel/clutch, the flywheel series is determined by your engine.

If you are using an aftermarket flywheel it subtly different.

TII trans means TII flywheel/clutch, the auto counterweight series is determined by your engine.

N/A trans means N/A flywheel/clutch, the auto counterweight series is determined by your engine.

 

Thanks, I understand now.

Hey JJcobm, I was checking out your thread from your sig. Really nice man, and I likr how clean you made everything look. Thats exactly what I'm going to do except the Transmission isnt JDM. How different did the car feel after the swap?

 

Well, besides it vibrating like a giant vibrator, it's good to be able to accelerate in 5th gear. Also, it's nice to have the LSD in the rear and the car is much more predictable if trying to slide it. Not much difference as far as drivetrain besides that, with the rest of the work I did though, it's a completely different car.

The only difference with the US spec and JDM transmission is going to be the 5th gear/backup light switch, which the JDM transmission lacks th 5th gear portion of it. Switches can always be swapped. And that reminds me, keep all your old parts until you are finished with the swap, you may need them like I did (could of just saved me time with the switches).
