I am contemplating a T5 conversion on my IROC before the new motor goes in.

There is a guy local to me that will sell the complete conversion but the tranny is not a WC T5 for $500.

What are the major differences between the WC and non WC? The motor is a slightly modified 350TPI. Probably running around 300hp.

As far as I know the only differences are in the bearings and gear sets. I'm pretty sure that the WC uses Timkin bearings, and the gears are cut different to handle more power. If I'm not mistaken, the WC has a torque input capacity of 330 FT. LBS.

All correct.

Couple questions to ask yourself:

Have you driven a stick?
Can you drive it conservatively?
Can you refrain from powershifting?

If you answer no to any of the questions, then the swap is not a good idea. The price is good though.

I was told clutch dumping and powershifting kill the T5's.
Change the fluid every season, and drive it conservatively, meaning, you don't have to baby it, but just respect it. You can put the pedal to the floor all you want, but make sure the gear is fully engaged befor doing so, and make clean shifts, and it will be fine.

That is pretty much what I was under the impression of. It seems that I am better off holding out for a T-56 conversion.

Thanks for your help!

from my experience its powershifting and traction that kill t5's

if you got no traction, aka dumping clutch and the tires spin then there is no stress on the transmissions i did the swap over the winter and i pound on my car and its still going strong

maybe, but T5's hold up pretty well against 305's, but your right. Traction would definately kill it even quicker.

One of the worst things on a T-5 is the factory shifter doesn't have positive stops. Get a good shifter and it will last a lot longer.
