will this be a problem?

What does the Factory Service Manual say about propeller shaft dimensions?

Yes.

Icemark

The Turbo and non turbo drive shafts are not interchangeable.

Nothing matches up, they are the wrong size, wrong length, and wrong bolt patterns.


So I am not sure what katkaroto or Chaotic_FC are trying to say as if they are not interchangeable, they don't fit.

Evil Aviator

Well, I don't know about that. There were several responses saying it was OK.

I think they were trying to say that they don't know the answer to the question.

i have a turbo drive shaft in my rx7 and my car runs great it has been for 4 years. Th drive shaft is from and 89 Twin turbo rx7. I have a 88 vert rx7, but if you guys say its not a good thing to do you might be right? or i did something crazy

Either

1) you have an entire clutch-to-axles turbo drivetrain in your car,

or

2) you bought a standard NA driveshaft that works with the rest of your NA drivetrain. a turbo shaft WILL NOT work with an NA trans or rear. Repeat WILL NOT.

ps...there was never a twin turbo 89.

there you go, shattering the hopes and dreams of everyone who sees the II mark and thinks it means twin.

Icemark

yeah, since there was not a twin turbo 89 RX-7... I guess your answer is just as factual.

And not saying that it is not a good thing... we are saying it doesn't fit!

I have an 88 GTU that I am planning on swapping a tii into. I am planning on buying it with a transmission. Can I run it with my current rear end (does have lsd) or would you advise against it.

Custom driveshaft, and the rear end may not last long with the extra power.

Geez, thick skulls around this place these days...

Yes you can, if you get a Tii driveshaft custom modded.

Spec.

Evil Aviator

Aha, I knew you could use it! See, you smart guys aren't so smart afterall!

My car has a gear-driven driveshaft made out of some 1982 RX-7 flywheels. All it takes is a little bit of custom work, no biggie. I saw the conversion on Wikipedia, so I knew it would work.

Actually, you can re-drill the flange on the N/A rear end to accept the TII d/s, i have seen it done.

Icemark

But he is not asking that... he is asking if he can use a non turbo dive shaft in a Turbo car.

Well then perhaps I should amend my statement. Without hacking, grinding, welding, cutting, or drilling on parts, my above statement stands.

Once you do enough work, you could probably make a shaft from a 72 dodge child molester van fit your FC, but then it wouldnt be a dodge driveshaft anymore would it?

I don't understand some of you guys. You would rather buy the wrong part and spend hours or days and tens or hundreds of dollars modifying it to make it work for you, when the correct part was available for the same price or less, would have been a direct install with no modification needed, and would have saved time and energy.

haha the people in this thread are scaring me....

as for hte modification ideas.... ive tried some of these "ghetto rigged" ideas.

i used a t2 trany to an auto drive line and a 1" spacer i made, to a na rear diff. While the car would move the vibration at speeds above 30 mph were scary... i got the car up to 80 and i was scared it was going to xplode it was so bad....

A drive line breaking at speed can be disasterous. ive seen them put holes in the trany tunnel and all kinds of crazy ****....

Do it right, it has to be balanced and safe. If anything have a driveline specialized shop modify it that knows what there doing, they will tell u if its ok, or dangerous.

If you going to use the auto driveline to go between a t2 trany nad na rear diff, have a shop lengthan it properly. an auto driveline does have the t2 trany output spline, and na diff pattern. but is to short by a lil over an inch or so.
thats right even iIthe KING OF GHETTO RIGGING, do not recomend "custom fitting" a driveline by your self.

You are full of crap. There is no such thing as a twin turbo FC. And we're not saying it's a bad thing to do, we're saying it cannot be done in practicality. The only way to make it a feasible swap is to do an entire drivetrain swap, really.
