VKEFI inlet manifold-
How well do they flow, due to the bends im assuming you couldnt go too far with part work other then matchporting to the head.the biggest restriction in the vk setup is the air flow meter, so by getting rid of it you will resolve that issue, also i have to agree port match it to the head and you'll be laughin.
Also the std throttle bodies, how good are they? would i be better off upgrading to a larger one like V6 commodore?standard throttle body is a good size but if you remove the air flow meter you need to use something else or fit different sensors to it .... i'd suggest a vn v6 (60mm) or v8 (65mm) is what to use.
Larger injectors
not sure how large i really need (im a carby person
)depends how much power your planning to make, but you could start with a commodore v8 or supercharged v6 injector.
Motec ECU
Cheap through a friend (was bought for his sprintcar about 3 years ago), not 100% on how much i can control with it, but im assuming it has alot of variables and functions, (motecs are pretty fancy units from what ive seen)
Im thinking of going to coil packs and distributorless, looking at using one of the scorcher dizzys (im assuming they act like a CAS for the computer?) and 3 dual MSD coil packs.i guess it depends what cheap is because motec isn't cheap when new!
i think it will do everything you need and more, but then i have never seen one in action so i really don't know.
delco on the other hand will do all you need and most probably cost less

coil packs are an option however you need a good crank trigger to drive them, another more cost effective solution is to use a je camira coil and ignition module and modify the dizzy to suite it.... put simply, the dizzy bottom section acts as a CAS for the computer and the top section of the dizzy distributes spark as it would normally, only difference is the computer tells the coil when to spark and not the dizzy telling it when to spark.
Also going to need to update my fuel system. (but have very little idea how far i need to go)
I know im going to need a electric fuel pump (holley?) will i need to fit an external pot?
Im more then likely going to upgrade the fuel lines and all the rest, but im just feeling a little overwhelmed by it all (fuel injection seems complicated
)holley pumps which i've seen are for carby applications and do not flow enough for what you need ....
you will need to get a pump specific to EFI and there are heaps around on ebay and in automotive stores, depends on power and how much you want to spend i guess.
the best solution would be a low pressure pump (something like a holley pump) to get fuel up into a surge tank, then have your efi pump suck out of the bottom of the surge tank and then it will supply the engine, the return line from the engine will then go back to the surge tank and then if the surge tank overflows its over flow will go back to the main fuel tank, this can be easily achieved with a fitting put in the side of the filler neck etc.
my car runs an efi pump straight from the tank using the original fuel lines then returns to the tank via the air breather in the filler neck, this works fine, but the engine will start to surge around corners when the fuel tank gets to about 1/8
i don't think you will need to upgrade the size of the fuel lines unless you are going to be making a fair bit of power.
I ha plans to have the blower on by christmas, but i figure this route will be a bit better, but may take longer.
anyone care to comment/lend a handI have just last week gotten the above mentioned VN injection running on a 202 and i am in the process of trying to get it running smoothly, it works great and is going to be a huge upgrade compared to the current VK injection i'm running, but its going to take alot of work to tune .... i'd suggest if you do go this route, get it all fitted and running then get the car to a dyno who can tune the delco for you, especially with a blower as you don't want to torch the motor.
if you want to go the delco route i am happy to share what i know about mods to get it working on a 202, but at the moment thats about all i can tell you

i'm planning to tune this myself cause i don't want to pay for a dyno, but who knows how i will go in the end!
