Hi will a 25 row oil cooler have to many rows for a 380bhp cosworth? or should i get a smaller one cheers

 

id say depends on what your gona use the car for ie track days or just normal driving!. for normal road use yu will want one thats got a thermostat so it does not cool the oil too much, if the cars going to get thrashed then bigger the better! just as long as you can mount it in a good place !

 

as said, what you using the car for?

25 cooler is big!, are you seeing oil temps in excess of 100 degrees?
