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.

dam man i swear to god the straight 6 i got aint in a pintara its in my VL commodore and i swear i can throw twin injectors onto it but not twin sparks but i would have to make a custom fuel rail previous owner did have a monster turbo on it so i got no clue its rb30e i think or t something i got no clue but i can only put twin injectors on my car i saw on my mates skyline he could put twin sparks so thats that what do you think ??? im preety sure i can fit more injectors to mine but i would need another head for sparks whitch i dotn know thne if i could put the twin injectors so yea

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"

      I was more thinking so it doesn't flop around as much rather than for rotating it. Once you have the balance right, it should rotate well enough, depending on how much resistance there is on the pivot. I think you said the pivot point was on a bearing though didn't you?

      You can get them with the worm drive rotator but I was too tight to pay another $250-$300 so manual labour it is! I don't think it will be too hard to rotate though.

      Sag as in the windows start to slowly open themselves, or they're just slow to go up/down with engine off?

      It looks like it needs a big worm gear drive on it to control the rotating, not a few sloppy pins!

      R32gtr sputtering and stalling

      As Duncan said, first there was OBD, which few cars used, then came OBD2.   Now an interesting point, OBD2 isn't even for what you want to do. OBD2 is for emissions testing. There is some sensor data on OBD2, but it's up to the manufacturer what they're putting on it. Most scan tools operate on UDS, which like OBD2 is a standard built on-top of CAN. UDS specifies how to structure a message, what very limited things mean such as "read memory address" but it does not specify what is stored in which memory address, that is all up to the manufacturer. You either a scan tool compatible with that vehicle, or to know how to reverse engineer all the data, which can take a VERY long time and a lot of vehicles to get it right. Oh and then the manufacturer does a firmware update and changes what's where... Ask me how I know that as fact Oh, and by the time you've got the scan tool that supports all the manufacturers stuff, well, you're back at "But a consult cable and the Nissan software" The main difference being most manufacturers software these days works with the same hardware readers, as the readers are built to support J2534 which is another standard for how the PC communicates with the tool to make it do specific things on the car...
