General concensus is Do It - I would, but I'm getting rid of my 45.

I have my own reasons for doing so, but if I were keeping it the SDI's I have would be going in...

 

getting rid? have you had enough of your clutch woes?

back to the OP - what sort of performance or mpg do you want?

If you want a lot of power I'd go sdi's primarily as it's cheaper than a remap, though you need both to maximise the performance to the limit, so usually it's best to do sdi as a first step really.

There shouldn't be a dramatic drop in economy, usually just comes down to how you drive it, but it's not everyones cup of tea.

No, not exactly - getting the Motability car soon I hope...

Only thing I found is that the MPG wasn't quite as good afterwards

Anything that increases fuelling (SDI's do) will have a detrimental effect on economy if it is utilised frequently.

 

I take it you haven't been a car with them in?
My advice would be to fit them, if you don't like them sell them for what you paid for.
I had sdis in my 25, the power is amazing compared to my 214. I do most of my driving is in town late at night and I averaged 46 mpg. Loved the damn thing.

They get put back to stock mostly when the car is sold, the owner reclaims the price for them.

 

They give a very noticable boost in accereration and performance.

Only thing I found is that the MPG wasn't quite as good afterwards although maybe it's because you can't help but use that pedal on the right a bit more.

This .

 

i have often thought about slotting some SDIs into my 45 derv, but then i think to myself "james, you have got 2 kids and a missus, having a fast car is not really the best idea in the world really now is it?" so unfourtunatly, as much as i would love to, its not really pheasable, so i shall continue to read in awe at new people who decide to do this mod.

Depends how you drive and where you drive. Slow cars do not always make the safest.

For example, out in the sticks where I am you can find yourself stuck behind agricultural implements for many miles. You can either sit there at 20mph or overtake.

If you choose the former, you can potentially add 1hr to your journey - if the latter, would you rather take 3 seconds or 7 to get past?

Exactly.

That is the difference between tuned versus non-tuned.

Just coz it goes like stink, don't mean it has to...

 

I'd go for it, it's not going to make it a rocketship, but your first impression will be 'damn this is a rocketship!'

 

Quite simply - when I added them to my ZS it was RR before and after and the difference was 26 bhp.

Do it.

Bit more smokey - but worth it. Cost me about 2 mpg combined with other mods at the same time.

 

Firstly as with any mod you need to be aware of any possible risks....although saying that my sdis have been in for a while and all ok as many other members would agree

Sdis are defo worth going for !! Will defo transform your car totally !!

Make sure the injectors are cleaned before putting them in and preferably from a lower mileage car ..

You'll get as much power as you would from a remap but for way cheaper ..

Mpg is not majorally different ...obv with the extra power you do tend to use it .. however Sdi to non Sdi driven in a similar manner there's not a major difference ..

It's not a majorly massive mod so u could always swap back if you didn't like them..

 

DO IT!! Just fitted some to my dads ZS and its improved it no end.. and hes still getting 55 mpg, he was getting 60 but 55 is still very good for the power they create!

 

ahh, £100 a set is a bit to much fork out for me, maybe i should just stick to £50 sets if i do decide to get some,is anybody on here selling any anytime soon?

between you and me I don't think cleaning does all that much with regards to their function.

Nothing cleans injectors like, well....hot diesel......at 1400bar....

Though a recon set, if done properly would probably have brand new nozzles. Now that I can't argue with, but would most likely cost more than £100.

 

I dont think cleaning does anything either, at the end of the day an injector is an injector, even if you have one thats done 20K and one thats done 150K they will still function the same..

 

Member 'Yellow-Sub' on here has or did have a set of good condition sdi's for £50 ish, i was going to have them but i found a set from my local scrappy! Its worth chucking a PM his way ...

 

well, sort of, an injector can get worn, what I mean is if this was the case cleaning would not really fix it, it'd need a new nozzle.

I'm just saying I wouldn't place too much empthasis on whether it's being cleaned or not, they do look the dogs ******** after being cleaned but it's just bling factor most of the time.

 

That's pretty reassuring - might bang mine in and have a giggle before I get rid, at least they'll be proven tested for the next fella.

Thats my excuse anyways :broon:

 

aye, go for it

 

with regular driving i found that the MPG's i lost with SDI's came right back after i had it mapped.

id defo say do it

 

would also advise cleaning, i see were the others are coming from but you dont know what fuel have been ran through them, could be abit of carbon build up, anything really. Least if there cleaned you know what is going into the car, not a unknown. Just my view.
You should go for it, great mod. Just remember new seals.

 

Totally agree, you need to get your priorities right.




Plus, there's nothing to be ashamed about divorce in this day and age.

 

Divorces cost more than a re-map!!!

Totally understand the priorities towards the family, i'm in exactly the same position myself.

Cash is tight, family comes first before modding the car.

If you do get in a position to get a re-map done, you'll end up wishing you had it done earlier.

Cheers

The kids will love you for it.
