Tunning a 1.5td

[Skeeny]

I've turned the fuel screw on my Nova 1.5td 90 degrees (quarter of a turn) clockwise as instructed but it doesn't seem to of made much difference to the performance, should it of? It doesn't seem to be kicking out too much smoke at the mo, could I turn it further or would you not suggest that?

you need a bleed valve fitting in the vacuum pipe on the turbo
it runs from the turbo to the actuator,
before you will notice any difference

Cool thank you

plus in y experience you should turn it up quarter of a turn at a time. a quarter of a tune isnt necessarily enough. i think i turned mine about two and half times when running 20 psi so it a case of keep turning it until its about right

I Turned My Fuel Screw Up Half A Turn And It Flys, I Have Now Fitted A Bleed Valve Aswell, It Would Keep With A Sri Easily Now And I Still Have A Cat :p

Ive turned my max fuel screw by about 4 turns a while back, didnt change what boost the engine made when the screw was at about half a turn. Think ive got a weak turbo actuator though, mine holds 15-16psi which isnt too shy considering thats nearly double the standard lol

I do still have the pump white ring fitted though, which i think may be restricting how much fuel goes in under boost....

Does the same apply for a corsa 1.5td isuzu engine???

[burgo]

yes mate its exactly the same

[MK999]

burgo you should diesel the estate :d Would fit with it's factory estate nova mile munching family wagon type image, and be a bit different, plus you know them fairly well!

[burgo]

fook that. to much work

lol did i really just type to much work!!!! with everything ive already done

[MK999]

eeeexactly lol and I never said what diesel.... :d Sure you can find something outrageous and mad to do lol

[Adam]

And for anyone asking, yes the mods in the articles section are well worth doing. You really do notice the difference in performance.

Just keep an eye on the coolant temps! As mine shoot up if i keep it on boost for a while......
Also, solid front brakes on a astra dont like high speed stops, brake fade tastic lol lol

[burgo]

temps shooting up might indicate you need more fuel ad

[Adam]

Think i need to do the white ring mod then.

Got to love these izuzu diesels, they just dont die/break down ever.... lol
