- - 13b N/A oil cooler core size? (https://www.nopistons.com/1st-generation-specific-16/13b-n-oil-cooler-core-size-69317/)

Hello --

I'm installing a 13b into a 1960 Bugeye Sprite. It'll be street ported, shooting for 130-150 HP. What size oil cooler core do you recommend for such an application?

Thanks.

depends on your application. If your racing I personally would go a little overboard for the safety of the motor aka dual oil coolers front mounted like you see in the aftermarket fd3s setup. If you need to save some cash go to the wrecking yard and pull off two oil coolers (air to oil NOT water to oil) from a 79-85 rx7.

2nd gen (86-91) oil coolers are great. i seen people use them on non rx7 race cars as well.
