Post subject:  AWD AT front ring and idler gear in MT

I want my car to have a lower final drive ratio.

I have an automatic W4A33 transmission and my C51PH manual transmission is in need of new syncronizers and is receiving steel EVO shift forks. So it will be in pieces all over my table...

Will the ring and idler gear for the front differential from the AT work with the differential in the MT?

I do have the automatic rear differential in the event I can use the front differential gearing.

I am tired of driving down the highway at 70 mph and watching the tach hang out around 3,500 rpm or so. No I am not spending $200 on the "200mph 5th gear" from T.R.E. when I have a lot of available transmissions and parts...

Looking at the FSMs the rings look like they can be swapped but what worries me it the idler gear from the automatic trans working in the manual trans.

I am going to take the big leap and go for it. Gonna have to yank the auto trans out of the car it is living in. Luckily, to get the front diff out all I ahve to do is take off a simple cover. Removing the idler gear will probably not be as simple. I will have to either use the four bolt from the auto car, if it is a 4 bolt, or get the ring and pinion out of it and put it into my 4 bolt.

Reducing the final drive is going to "lengthen" my gears. I am also using a JDM GVR4 trans, C51PH, so it already has a lengthy first gear and slightly different gearing from the stuff we have here in the USA. If doing this does not get my cruising RPMs down I guess I will be buying a taller 5th from some vendor.
