20V turbo into 1991 CQ

[Pedro Rodriguez]

I am seriously considering transplanting the 20V turbo engine from my 1991 200TQ into my 1991 CQ.  The 200TQ has almost 200K, but all major components are fine (I drive this car everyday).  The 1991 CQ has about 70K.

I have compiled some very helpful information about the transplant, but I guess there is never enough.  So, any comment or suggestions are most welcome.

My question, however, has to do with the gearbox/front differential.  I believe that physically the gearbox/front differential are the same in both cars.  Does anyone know if the gearing is the same?  If the gearing is not the same, is the gearing on the 200TQ gearbox closer to the S2 gearing than the CQ's?

Thanks,

Pedro
