D4D engine mods

[F117]

Hello ppl!
I own a Yaris d4d 2013 90hp.
I could like to know if anybody have put a bigger turbo...a bigger ic....a bigger fuel injectors.
What modifications i can do to gain over 50hp?
I know about chips but i could something more effective.
THanks a lot

Anybody?

we don't have the diesel in the USA, but those are the types of things you would do. i would think the first thing would be a ECU as toyota has a way of keeping things mellow. you could probably squeeze 10% gain in HP and +15% torque from stock. then when you add on larger things you can appropriately adjust for the gains. IMO

The thing is that i have already a chip on it....but... i want more.... +50 at least...
But i can find on net one single person that have done any modification with bigger turbos etc etc in order to have someone to show the right way.....

no, not chip. stand-alone computer. full engine control module. then, the largest intercooler you can fit. turbocharger might be slightly bigger, most likely a different impeller only. i wouldn't go super huge and loose all your low-end, that always sucks. stock should be close to perfect. propane injection is a good adder for diesel, so is a water/methanol injection. if you add both of those you will get your +50hp...

If you want to get 50+ more HP, buy a new car! Realistically though, if you plan on increasing the rated power by more than 50% you will need to do a lot of mods with the right supporting mods. Bigger turbo, bigger IC, tune, engine building, etc. At the end of the day if you want a car with 140 HP just buy a corolla, celica, matrix, civic, etc it'll come up cheaper in the long run.
