Hi, Does anyone know how to obtain more power from the 1.9 SDI engine?:confused: (chips, exhausts, air filters etc., plus what power gains would be expected, if any?

Thanks terry007

K&N or green filter may help a little but apart from that it's very expensive for little gain

The SDI can be remapped, i have done a couple but as said gains are much lower than turbo cars. You would be looking at about 8% increase

can you not fit a turbo onto a sdi?

Not cost effectively - you'd need to re cam etc to open the valves longer to take advantage of the turbo - too exppensive when you can sell the car and buy the turbo'd one for very little difference.

As a general rule your correct however quite a few people who own a 1.4tdi for example enjoy the challenge of tuning the car & the performance from something which really shouldnt have that power.

That's a really good point, I never even considered that - I was thinking about the 'easiest' way to get the power, not necessarily the best or most enjoyable.

I can guess there's a really good sense of achievement doing that.

Or buy the best one available and then perform an "open engine transplant"

Surely nobody would be silly enough to undertake such a task

I heard an old wives tale that only people in the far south west attempted that kind of trickery

i drive a vehicle with the sdi engine at work everyday great little workhorse with over 110k miles on the clock........ vw caddy van thoght there was no need for more power untill i got my fabia...... nevermind the van will soon be replaced by a new caddy 2.0 tdi hehe

you can fit a powerbox The dragon one is good and cheap.

also an air filter.

as an alternative to the powerbox you could swap the injectors for highr flow ones.

it wouldnt be a good idea to do both you'd just make smoke.

rule of diesel tuning smoke =too much fuel.

so you add more air
