Formula Atlantic | Rally | MR2

Building the 1600cc Toyota 4ag engine, Hasselgren won the Formula Atlantic “TRD Engine Builder of the Year” award for 8 consecutive years, 1996-2003, before becoming the Series Spec Engine Builder for 2004 and 2005.
Hasselgren has continued to develop the engine for SCCA Club racing and in 2009 won the National SCCA Runoffs at Road America, the SCCA Triple Crown and the SCCA Super Sweep, driven by Mirl Swan.

Hasselgren has a billet oil pan available for the 4ag, with improved performance and strength over the TRD casting.
