Author : Lee Jansen
This web site provides information on turbo charging engines developed by British Leyland Motor Corporation for Triumph and TVR automobiles. Several individuals have turbo charged the in-line 2.5 liter engine that was installed in the Triumph TR250, TR5 & TR6 models and the TVR 2500M model. The dual carbureted version of this engine provided to the US market was advertised to produce slightly over 100 HP while the European Lucas PI version produced up to 150 HP. The US engines were equipped with compression ratios as low as 7.5:1 and low cam overlap to comply with stricter US nitrous oxide emission standards.
