Hi i have a 2004 D4D 1.4diesel Yaris T-spirit. 75hp how can i get a little more hp without changing engine ?I.E. Bigger airflow ? Upgraded exhaust ? I have no idea

you can do all the supporting mods but without a tuning box from likes of dtuk or a remap its pointless, some of the early diesels are partly mechanical so tuning is not possible

your looking at £500-1000 to gain 20% if your lucky https://www.diesel-performance.co.uk/tuning/car/toyota/yaris-from-1999-to-2005/1-4-d-4d-nlp10_-75ps55kw-1364-ccm/#go

 

if the engines has done more than 80K miles you are going to shorten the engine's life significantly by tuning
