martini928

Here is the situation:
I have 928GT '89 but the radiator is from (IMHO) S4 as there are auto transmision oil cooling built in it (two holes in passenger side). Whould it be a sensefull solution to run custom engine oil cooling lines to these vents and use the radiator for engine oil cooling. In this case I will not have to order an oil cooler and exchange the radiator....

Please, ASAP, have someone done this?

The rad in (my) '88S4 auto (928 106 043 01) has a cooler in each end tank: the left side (driver) is for engine oil, the right for auto xmission.
If you are adapting a S4 auto rad to a GT, I would think that the engine oil cooler fittings are identical - on the left; therefore, no modification required.
The 'right' cooler could be closed off.....
or, do you have the 'trans cooler only' rad from'90-'94, # 928 106 042 03? - ie., only a single cooler on the right. If this is the case, it may be easier to purchase and install a sererate, dedicated oil cooler.
