I'm not exactly well knowledge with car mods, but a friend of mine mentioned getting a carburettor... as a joke ofc and I thought about Individual throttle bodies, now would getting an ITB's for a c14nz be beneficial in terms of horsepower gain, or am I complete dumb idiot for thinking such things.

while I'm at it, is it possible to go from 8v to 16v with just swapping the head out(and of course some other parts but keeping long story short)

in answer to your question, ITBs do increase BHP but it's not just a case of throwing them on.... would ideally need standalone management for that I'm afraid (I have ran ITBs, also a turbo through them at one point!)..... You would be far better looking just to convert to multipoint which other members have done before- await for their comments as I'm not sure if there were just straight plug and play swappy jobs..... I know my dad managed o run multipoint and was a massive improvement from single. It also sounded insane with just a cone filter on the multipoints so if it's the induction noise your after with the itbs then it gets another big tick on the multipoint.

yea i fully understand it isn't a straight lego set swap and doesn't MPI need a bit of extra wiring for it to run properly?

and also what parts are we talking for a 1.4 spi -> mpi swap?
MPI parts you need:
  • Cylinder head, inlet manifold, throttle body etc
  • Throttle cable, servo vacuum hose, coolant hose from inlet manifold to heater core
  • Engine wiring loom
  • ECU
  • Fuel pump
I converted my 1.6 SPI to MPI many years ago, was well worth it when I was 18 and wanted a bit more power for not a lot of money.

If you wanted ITBs or carb(s) then they can give great results, but you will need to ditch the stock ECU and run an aftermerket ignition system.

16v conversion would require different pistons.
