SI engine compatible with DX Tranny??

Will a DX Tranny and clutch work with an SI engine???????

sure will

Are there any disadvantages with using a DX tranny?

only difference in the DX and Si tranny is the final drive

What T-Mo is saying is that the final gear the is taller in the DX so you will get more top end in the dx, but it will be slower on take offs. The Si will have less top end and will be faster going thru the gears.

Si = Speed up quicker
DX= Better gas mileage
