v8 injectors on a 6

slickute88 · 23-07-2006, 08:35 PM

hi just wonderin if 8 injectors on a 6 would fit and if so would it be better///

Hi and welcome to the forums.

The I6 injectors should be fine, even with a fair amount of mods. If you inject anymore fuel into the eninge, it will run rich, and you will loose performance. If you want some low cost starting mods, check the Performace Mods sticky at the top of this forum page...

wat about a lightened fly wheel

slickute88 · 23-07-2006, 08:46 PM

or twin throttle bodies do .. they make them for au's

or twin throttle body manifolds do .. they make them for au's

All of the above are next to useless on an NA I6. Go turbo or supercharger, and then these may work effectively. More petrol does not mean more power. But more petrol with lots of compressed air means fun!

ohok ...there was a commowhore on a web site wit twin throttle bodies and 8 injectors...just wonderin if it actually produced more power..but obviously not..

It might have but you need to look at the other mods that went with it.

Your injectors will cope just fine until you start to seriously modify your engine.

As you get more into doing up your Ford properly, you will realise that there are quite a few commodores (I should actually say cars) out there, many with useless mods... V8 injectors, larger exhaust tip, larger tb's. Like you have done, you need to first ask what benifit they will give to performance, or with what combination of parts, which is what you have done.

eg. A cam on it self may give you car a 10-30kw gain, but with a flash tune, you may find it can give you upwards of 50kw gains. Same gos with allowing more fuel and/or air into the engine. The mods that do this may not give massive gains, but get an edit, and you will get a small/decednt gain. But edits are only really worth it, after getting:

Intake, filter, exhaust, extractors, and more specically, cam, then your edit. These mods combined can give you in excess of 50kw on the AU....

Good luck....

Check the colour of the injector you have and look up what poundage and flow it is. It might interest you to know that some model V8 injectors are smaller than 6cyl ones. When you divide engine displacement by number of injectors 6's actually have to provide for a bigger displacement per cylinder. My pursuit 250 actually uses the same injectors as a previous model 6 cyl with increased fuel pressure. This was done by tickford. Mine are the blue as used in the sixes. Having said all that you usually have to do a fair amount of mods before you max out an injector. Talk to an expert they have a formula to apply to see if you need to go a bigger injector

how much is a cam and wat cam is best suited at a resonible price....

8pAc · 24-07-2006, 07:12 PM

Start off slowly dont just jump in with a cam. Extending on what was said above, if you just whack in a bigger cam without making sure that you can firstly, supply the air you need via the intake and expel via exhaust you will loose power than you had to start with.

Start with and exhaust system and if your car doesnt have an lsd do something about that.

PS WHAT WHAT WHAT WHAT WHAT WHAT....

It depends...

A cam can start from $500 just for the cam, but then you will need installation... this price can go up, depending on cam performance, and what materials it is made of... best value for money depends what you want... do you just want a cam for the sake of it, or do you want the most performance, but best economy, etc... a high lift cam with edit would be best value for money for max performance gain, but your looking at about $1500 for a good dyno flash tune, and maybe $1500 again for the high lift cam (labour included).

A cam is not worth doing if you do not have an exhaust. If you keep the stock exhaust and put in a higher lifting cam, exhaust gases will flow out of the cylinder easier, but there will be more pressure put on your exhaust manifold, rather then the pressure being put on the exhaust outlets... so basically, it will provide next to no increase... you will probably get some, but for $400, get a 2.5" exhaust... for $1000, get a 2.5" exhaust, hi flow cat, and pacemaker extractors... labour included.... this is the best value for money (bang for buck) bolt on mod that you can do... while you at it, drop in a K&n filter panel....

This is pretty much the first half of the Performance Mods article.....

slickute88 · 25-07-2006, 05:34 PM

the mods i have already done are ....tickford snorkel,extractors ,exhaust,quickshift,

Cobra · 25-07-2006, 11:14 PM

What exactly is a "quickshift"? If you have a manual I'm guessing you mean a short throw shifter, and if it's an auto I'm guessing you mean you have a shift kit?

EvilChief · 26-07-2006, 06:21 PM

correct me if i am wrong, but AFAIK the V8 injectors are similar size to the 6 ones .. just an extra 2 :p

bodes-sh · 26-07-2006, 06:59 PM

well if you work out the cylinder size, eg 5/8=0.625ml, 4/6=0.667ml, so the i6 injectors must be slightly bigger being that the actual size of the cylinder is...correct me if im wrong somewhere

My AU1 XR8 has the bosch blue injectors (24lb/hr), and the wagon has the blacks (18lb/hr). These are max flow rates and have nothing to do with capacity of the engine. In fact, the blue ones are the same as on the late 90s/early 00s V6 magna.

Free347 · 26-07-2006, 08:45 PM

Actually they're not the same. The Magna injectors (also used by HSV) are designed to deliver 24lb at a much higher fuel pressure.

EvilChief · 26-07-2006, 08:55 PM

i was refering to the cc sizing .. fuel pressure brings a compleely different ball into that game
