202 EFI vs Carb, blue or black motor?

[KiwiKommy]

Read in several places of people ditching the efi off a 202 in favour of a carb for more power and reliability?
If so, what wiring mods would need to be done on a black VK 202 with efi to convert it to carb? Would the electric fuel pump still go, and be suitable?
Was thinking of just unpluging the fuel injector wiring loom from the main harness and leaving it at that.

A redline intake manifold seems like a good starting point, but what sort of carby would suit? I have seen tripple webber setups that look the part, and also single hollys...?

Lastly, wanting to rebuild and engine to put in my commy without having off the road for months. Second hand black 202's are a bit hard to come by round here, but plenty of blues are about. Is there much difference between the blue and black block and heads??

Thanks

I have just recently rebuilt a black 202 with efi. I found out that the Blue 202s are the same as the blacks. The efi versions are anyway. The heads will physicaly fit onto either, just be carfull that the holes for the water jacket are all the same. The earlyer red 202s have a different hole pattern.

I rebuilt another engine while i was still using the old on in the car, then it was just a simple mater to swap them over in a weekend once it was ready.

Good luck mate

Blue and black bottom ends are nearly indenticle.
Now who ever told you the carb was more powerful and reliable is smocking the horses dung. The carby is better for fuel economy and thats about it, reliability it is not, cold starts are a bitch amongst other things like tuning, but yes they are more simplistic and less likely to have an electrical fault. The EFI is good for cold starts and jump in and go, plus alot more power, and more reliable. So if you want realiability and power keep the EFI.
Depending on your laws over in NZ, but in Aus (vic) you cannot put a blue motor in a VK.

Tom is correct but one thing i'll add is blue 3.3 are almost intdentical as black but blue 2.85 are totally different. Penrod there are a host of differences between efi motor and carbi versions. EFi heads are different to blue heads but you can use a blue head with efi
I would keep the efi much better than carbi if you keep it serviced and well tuned with good clean injectors you'll find fuel economy as good as putting a bigger carbi on.

the blocks are identical, Blue and EFI heads look similar but have a different casting ( the port shapes are changed only), Black carby heads are again different ( they have air injection like the BLue 2.85 engine)
as for power and reliabilty.
The EFI has more power (they ditched the 253 for them)
The carby has better economy
and they both have pros and cons for reliability
for example
they all still use the crappy plastic dizzy cog ......GGGGGGRRRRRRRR (pain in the ass, usless thing, that strips at the worst possible times)
the Blue and Black carby engines use the same Vara-jet carby which is prone to having the power needle valve stick,
the EFI ones use a fuel only dinosaur age system with no diagnostic alert which cause hours of frustration with the same dizzy as a blue motor,
and the Black Carby has the EST ignition which can have similar electrical frustrations to the EFI system,
just to name the most common

in me vh we had a blue 202 with the injection gear on it with a 4spd, didnt go too bad, i bet a vn calais haha boy he was p!ssed

i don't understand how a carbie can be more efficient than efi......it just doesn't compute???.....lol
