Porsche 944 LS Swap: Custom Radiator Upgrade – Part 1

February 25, 2023

The original radiator in a Porsche 944 is a paltry 24″ x 14″ which is just enough to keep the little N/A four-cylinder engine cool. However, since we have a modified high-performance LS V8 in our Rally car, the OEM radiator isn’t going to cut it. In fact, our original upgraded radiator, a 24″ x 16″ couldn’t even handle Rally racing. So, with advice from a fellow 944 LS Swap racer, we purchased a 24″x19″ dual-pass racing radiator. This video series will show you how we are going to cut and modify the vehicle and radiator to fit properly, and get enough airflow to keep our LS racing engine cool.

The Porsche 944 is a sports car manufactured by German automobile manufacturer Porsche from 1982 to 1991. A front-engine, rear-wheel drive mid-level model based on the 924 platform, the 944 was available in coupé or cabriolet body styles, with either naturally aspirated or turbocharged engines.

The LS based small-block engine is the primary V-8 used in General Motors’ line of rear-wheel-drive cars and trucks. Introduced in January 1995, it is a “clean sheet” design with only rod bearings, lifters, and bore spacing in common with the longstanding Chevrolet small block V8 that preceded it as the basis for GM small-block V8s. The basic LS variations use cast iron blocks, while performance editions are all aluminum with cast iron cylinder liners. The LS small-block has been manufactured in three Generations – III, IV, and V – with preceding Generations I and II of modular GM small-block engines having been based on the Chevrolet small-block V8 originally designed in 1955. GM recycled the “LT” designation beginning with the LS Generation V “LT1” in 2014.
