Have you tried doing a search on this topic?
I'll be nice ...unlike some others!!! Do a search first. :grinyes:
Just to sum it up for you.... From what I understand that type of swap is a bitch!!!
FYI... it's called a 420A to 4g63 swap.

lol you might change this but just in case you dont. its actually a 4g37 to 4g63T swap. yes it is a pain in the ass. some people say its easy but they never can prove how they did it and they usually end up being 12 year olds with too much time :biggrin:

check out vfaq.com but just to start you off you will need at the least.
engine
wiring harness
ecu
possibly trans
clutch
flywheel
starter
turbo
intercooler
intercooler piping

well I have a friend with a 92 laser and it came with a 4g63 so it couldnt be that bad and do u want aa turbo or NA

Thanx 1stgenrocks... shows what I know!!!! lol

i myself a 93 eclipse that has a 1.8 and i have another that has a 2.0 and i have an extra engine with turbo for both of them. in order to do the swap you need: the ecu for your engine(turbo ecu if you plan on putting in a turbo);new transmission (the number is f5m33); driveshafts; wiring harness; the gauge cluster is different (1.8 redline= 6,000 rpm / 2.0 redline= 7,000 rpm); starter; plug wires; distributor and cap:different fuses for certain things; and last, lots and lots of time and money if you want it done right. if you have any questions or need any parts let me know. You can instant message me at cjackson217 and i know a good bit about the d.s.m. mods

i have a 93 ecilpse 1.8 sohc i want to swap it to a 2.0 turbo dohc how hard is it to do

3 year old topic back from the dead haha.

Maybe searching isn't the answer. :P

hard..
but its easy to revive old threads

Just buy a turbo car if you want one.
