ok i was looking the other day at my r31 block and i saw it had space for 12 injectors on the intake manifold where they kidna sit but the block was shut off obviusly couse u need the compression then i looked at my mates car and he could wack on twin sparks and twin ijectors is this really possible and why if it is how much money would it cost and would it be worth bolting onto the bottom end of r31 block couse they are like bullet proof and is it possible to set up the twin fuel twin spark stuff and worth doing would you need a turbo or not and all those questions your help will greatly appreciated thank you guys

bwahhahaha!!!!!

f*k man im pissing myself!

thats probable one of the worst posts i have even seen!

its even worse than george bryants '.. wheres my ignition,...' or " ...What are my nuts for...."

"... can my petrol car be converted to diesel?..."

but hey im sory for being a prick, its just this forum has really turned into a circus lately...

as to your question, it sounds like you have an R31 pintara, which has a CA20e engine, basically a very simple and effective unit. the twin spark is standard, and some owners remove one bank of spark plugs for some reason or the other.

it is highly unlikely the RB30 has extra injector ports in a STOCK manifold, maybe if it was an oldschool aftermarket?

if you can get some pics it may help...

sorry again!

you do have a big imagination:

an rb30 has no allowance for extra injectors, the head/manifold (been a long time since i've had to pull on apart) only has 6 x injectors slots (for lack of a better word) and there would be no real reason to try to set up a twin injector thing unless you had crazy money and couldn't think of a better way to waste it. if you want more fuel because you are adding a large turbo then look into GTR or VL turbo injectors or even aftermarket items.

OK

i kinda see what he is getting at.

I have seen on a very old turbo VL, (when EFI was still in a basic stage of modifying i guess)

it was a custom plenum with a secondary set of injectors that would start spraying when the boost went above a certain psi.

a very OLD and CRUDE way of getting around the leaning out of stock injectors...

now days we just get a remap and a set of bigger newer injects, and a dyno tune....

ahh see i knew it could be done say fi ur running an incredible amount of boost and you throw bigger injectors but still not enough and u double up then? like would the stock ecu even be able to support 12 injectors?

there is no way to mount extra injectors on an stock rb30 unless you drill into the manifold.....

notice he said "custom plenum"

    • Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...
    • My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.
    • I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.
    • I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended
    • Yeah mate, no probs. Just swap the email addresses?
