Tracy,
Wait... =A0am I reading this correctly? =A0 Your suggestion is t= o put the turbocharger oil drain on the spark plug side. =A0Seems like a lo= ng way away from the turbocharger to move the drain. =A0 Is there some bene= fit to doing this? =A0 I could see a benefit to doing this for the redrive,= but not for the turbocharger. =A0Am I somehow missing something?

Optio= n 1. - No, for the reasons you said.
2. - OK, but more trouble than it's worth.
3. - Would work.<= br>4. - Works fine .

Best is to drill & tap foot of rear ro= tor housing on spark plug side.

Reading on an rx7 forum I've learned that there are multiple opt= ions for the turbo oil drain on an NA engine.


I can weld a bung into the oil pan
I can change the front cove= r to the Turbo 2 one
I can drill and tap the NA cover to accept a -10AN = fitting
I can make a oil metering pump block-off plate that will accept = a -10AN fitting


My concerns are that that option one would put the drain oil below= the oil level and add restriction. Option 2 would upset an already rebuil= t engine... don't mess with perfection. Option 3 of the available ar= eas to drill and below the OMP pad and further down on the cover... the sla= nted section, which one would be better?


Option 4 seems best but it seems a little high and it too may cause= some restriction.


Has anybody used the OMP block-off-plate drai= n idea with any success?
Should I just put my big-boy pants on and take = the front cover off and either switch the front cover or drill/tap or tig a= bung to the lower section of the front cover well below the OMP pad?


Advice sought.
