Cultus carby engine swap (2004)

[pwuser168432791191]

I have a 2004 carby cultus, with abysmal mileage of 8-10km/l . Looking for an engine swap for better fuel efficiency.
Which is a bolt on swap? also which among these are better especially thoughts on
K10B (new cultus engine)
G10/13/15
K10C turbo (RS turbo swift, is it available readily?)
or swift / baleno engines
I'll prefer a newer engine with good efficiency, which doesn't break the bank.
Any suggestions are appreciated

G10B if you want an easy bolt on swap or G13BB with a 4spd auto if your looking for power and ease of driving in traffic and better fuel economy than the G10A,

G10/13/15/16 all are best possible fits as suggested you in inbox.

what about a g13b from an older swift gti? is it available in market?

[the_mira_guy_08]

Good luck finding one that runs. It'll need a complete rebuild.

and i'm guessing parts would be a pain in the backside to find, right?

what do you think about a m16a or m18a in a cultus?

[the_mira_guy_08]

It shares parts with the all the other g series so not really. If i wanted to get it rebuild i would go with aftermarket bearings, gaskets and rings.

[the_mira_guy_08]

M13 would be much better swap since it's more readily available.

For cultus g15/16 are best swaps. M series is alot of cut and weld. Part availablity of g series is very common and easily available.
