hi guys was wondering if anyone knows or has put bigger injectors into there polo.
mate has a cossie and he was saying that he put bigger injectors in and it made a hell of a difference. would that be because its turbo'd or would this work for any car i.e the polo Gti.
any help please..
bigger injectors?
No mate.
No matter how big your filter is your TB is still the same size.
Im expecting the standard injectors will be fine with an ajustable fuel regulater, even with twin 40 throttle boddies.
Bigger injectors on a stock engine is over kill imo.
The stock injectors are not max'd out so upping the pressure would do the job fine.
But remember add more fuel, and you need to remap the ECU.

Is it ajustable?
Just be carful not to max out the injectors.
As I say, the ECU doesnt have enough self ajustment to cope with a huge increase in fuel.
so you run the danger of adding one of them ebay 'tuneing boxes' by running the engine too rich.
Its a tricky one mate, I dont think your gonna get any gains, without fitting a larger throttle boddie (I have heard of someone useing a larger mk4 gold tb.) and mapping the ECU.

Depends how much you want to spend really.
The biggest cost is the ECU and mapping time.
I think Ive spent £560 so far on the Throttle boddies, air horns and fuel rail.
Linkages are £80, manifold will cost between £80-£200 depending who you know, although I am trying a spacer plate a friend of mine is making for me, to allow a direct to head (ish) fitment.
This should cost no more than £50 (again, another 'ish' here)
The standard injectors may be fine, like I say, but replacments shouldnt cost no more than £30 off ebay.
Then you'll need to change your flyby wire throttle, to cable.
You'd need to mount a trigger wheel (around £50 for the bits) to the crank for the timeing, and a bunch of sensors.
ECU can cost as little as £160 with a loom, if your able to map it yourself, or up to £600 for a DTA unit that most tuners will be able to map.
Mapping should cost between £300-£450
Im no where near ready for it all to be installed yet, so if we say there may be another £500 for problems I dont know about
If you have the cash, and give Mr Bill Badger5 a call.
He offeres a supply and fit service.
I forget how much it is, I think it may be around the £3500 mark.
Should be good for 180hp on a GTi lump Id imagen

hey, i got the low down from bill, at badger. i was shocked at the price. the price he gave was about £2000-£2500 for parts and that was without fitted i think and defo without the remap. not going to go for the trottle bodys, going on hols with the bird so that drains the pennys away. but on the look out for a 1.8 20vt out of a right off, so ill see what happens.
