Alain just wants you to listen.  He's willing to share his vast knowledge on this kind of thing, as long as you don't contradict him.

He's a information dictator!

I wish more peoples would try it  but since there are no "kit" for the swap and you need to built your own engine too it makes people nervous
yet it's a more doable swap than the 4g63t

i'm willing to do it, but what would be better for speed? I'm stuck driving a slowass 82 diesel jetta 

again what do YOU want ?
and what do YOU have right now ? most ES were v6
and how much you want to spend

let say you want an all motor car, (newbies take note all motor = no turbo no supercharger but Nos is ok, only a honda boy will say that he drive a all motor turbo civic )

to make power you will need a profesionnally ported head , a set of powerfull camshafts, a set of cam gears, a set of valve springs and an updated sets of rockers and lash adjustors
the same head is needed for either a 2.0 or a 2.4  the difference will only be choice of camshafts, like Crane #18 for a 2.0 and crane #22 for a 2.4
either the 2.0 or 2.4 you won't find a decent header on the market that makes power, because you need a true long tube header and it will need to be custom made

so head = same cost 2.0 or 2.4

bottom end forged pistons and forged rods cost the same 2.0 or 2.4
block: 2.4 cost a little more because 2.0 you could grab neon block by the dozen

pan: custom 2.4 or a decent pan like the moroso = same cost

fuel 2.0 would need #24 or #30 injectors  2.4 #30 or 36 or even #42
however the cost is pretty much the same

2.0 direct fit 2.4 you need some engine mount and creative work for power steering

exhaust work same cost

results : potentially 180-185 whp on a 2.0L for several thousands , 230-240 whp on a 2.4 for several thousands

now let say you want a commercial turbo kit
the cost of the kit is the same
engine wise the 2.0 would need forged internals
the 2.4 could use cheaper $wise but still very strong srt-4 internals

the head could even stay stock , same cost for the 2 engines

block : read above a second time

pan : read above a second time

the 2.4 will delivers tons of power 350 hp at 4500 rpm is easy to do
the 2.0 could delivers too but a 7000 or more rpm for the same hp
torque wise the 2.4 will be way ahead of the 2.0

if you only want an engine with a few bolt ons like 95% of the peoples out there don't even bother researching

Alain

its a 4cyl es.

Just turbo it with a premade kit like a hahn or treadstone turbo kit and be done with it.
Once you can't stand lower boost then rebuild the motor/get a better fuel system and up the boost

the do what I am doing

Build up the bottom end, prepare the head and go for it.
