Putting TII Tranny in NA car. I HAVE A QUESTION...
I am puting a TII Tranny, driveshaft, and rear end in my race car. (second gen body. ) the engine is an N/A so the NA flywheel will be used.
I am pretty sure that i will need a Turbo II clutch disk, and a N/A pressure plate. does anyone know differant then this? or does anyone know for a fact that this is true?

your t2 trans is not going to work with your N/A flywheel. the starter is to low on the bellhousing and will not touch the ring gear on the N/A flywheel. you will need a t2 flywheel and clutch setup. Other wise it should work fine.

so let me get this streight
TII front ballancer
TT flywheel
TII clutch and pressureplate
TII tranny
TII Driveshaft
TII rearend.
N/A engine.
all of this will work together?
wont the TII flywheel and balancer be off since it is a N/A engine?
i have been told many differant things. i have also been told that you can use the N/A flywheel with a TII clutch disk, and a N/A pressure plate. with a N/A starter.
it seems like everyone has there own oppinion. does anyone know for a fact what it takes to put a TII tranny in a N/A engine?
for those of you wondering why i am doing this, i have a drag car in the proccess, and the N/A bridgeport will destroy the N/A tranny (in my oppinion) and i belive the axles are stronger to...
anyways, thanks for any help you guys can give.

DO NOT change the front balancer, it is completely unnecessary and will throw off the balance of the rotating assembly. The front balancer, rotors and flywheel are a balanced rotating assembly. If you change any of these components, you will throw off the balance. Yes, the stock TII flywheel IS heavier. NO, you should not use it. The series 4 TII flywheel is around 28 lbs, the series 5 TII flywheel is around 23 lbs. The series 4 N/A flywheel is around 22 lbs (if I remember), and the series 5 N/A flywheel is around 21 lbs. Your best bet is to buy the correct counterweight for your rotating assembly and buy a lightweight TII flywheel. You can buy a VERY cheap flywheel from Dyson Rotary in Australia and save QUITE a bit of money!! Buy the counterweight from Mazdatrix. The addition of having a lighter flywheel will provide many benefits.

forget mazdatrix and their $134.11 counterweight...buy one used on the forum. just make sure its from the right series of car. they can be had for like 40-60 bucks. if you want to stay in the states for the flywheel then ACT's XACT flywheel for the T2 is like $225 from a few places.
edit: and just to clarify the counterweight/balance thing. the counterweights balance the assembly depending on the ROTORS that are in your engine. leave your front one completely alone. the rear counterweight from an S5 automatic rx7 is what you need. the manual transmission cars had the counterweight built into the original flywheel, but the automatics have a seperate weight for it that can be used when you buy an aftermarket flywheel.

You can use the Racing Beat special clutch/pplate that allows you to use an N/A flywheel and a TII tranny.
225mm Disc w/turbo
spline - 6 puck
Part Number: 12527
Retail Price: $107.00
225mm w/turbospline - 6 puck (right)
(for use with 1983-92 non-turbo flywheel and 87-91 turbo transmission)
Race Clutch Disc
This special application Race Clutch Disc is designed for drag and road race use. The disc incorporates six (6) sintered copper pucks and a rigid hub for quick, positive engagement, greater fatigue resistance and improved heat dissipation. The sharpened engagement/disengagement characteristics of this disc require careful driver attention - this disc is not intended for street use.
As with all of our clutch products, it is built only from new parts.
Time Saving Tip: We strongly recommend replacing the throw-out bearing during any clutch work to ensure trouble free performance. Also, we recommend replacing the transmission front and rear seal kit when re-installing the transmission to reduce the possibility of leakage. (See bottom of parts list).
WARNING: None of the Flywheel or Clutch components shown in this catalog should ever be allowed to exceed 10,500 RPM under any condition. This same RPM limit applies to stock components. You must use an engine RPM-limiter to prevent excessive RPM. If your engine is capable of exceeding 8,500 RPM you must install a transmission scatter shield, or ballistic blanket. Failure to implement the above may result in serious injury or even death.

If you currently have an s4 N/A engine with s4 counterweights, you can get an s4 TII flywheel with s4 rear counterweight (for lightweight flywheel, stock has it built it) and it'll work fine. If you get an s5 TII flywheel this will not work.

any idea how it works? seeing as how the flywheel will still be too small for the starter to engage its ring gear?

hehe, well see the T2 flywheel is bigger in diameter, and thus the starter would be mounted further out from it seeing as how the starter bolts up to the transmission. so basically, if you are running an NA flywheel, the starter's gear doesn't reach the flywheel's ring gear. maybe they push start their race cars :p

putting it down daily
I am running this setup on my 88 na vert- (stock s4 n/a motor)
S5 T2 tranny, act chromoly flywheel, auto counterweight
stock t2 clutch disk w/ act HD pressure plate
t2 starter, slave cylynder, torsen style diff, driveshaft, and rear axles
and she runs just fine. I am in the process of saving up for a built t2 motor, and elected to go with this setup so I could still drive it around.
Hope that clears things up.

now we are on to something!!!! yes this is for a race car, so harsh engagment is just fine! (drag car)
i have been told that the starter hold in the TII tranny is no furthar out then the N/A tranny, the only differance is in the starter. the starter is built with it "pulled back" in the design, to accomadate the larger flywheel.
so with every thing we have said, the following SHOULD be true and work.
N/A front balancer
N/A engine
N/A flywheel
N/A starter
RB special Clutch
N/A pressure plate
TII drive shaft
TII rear end
any one dissagree? and why?
