ej20t engine into L series
hi my names Rob
i currently have a 90 L series with a 1.8l ea82 engine
i am planning to put a ej20t engine in it
is it reasonably easy to do ?
i want to keep the original gear box for the hi and lo gears
is there any chassi mods involved ?

G'day Rob, welcome to the forum.
Probabily best to read this and remember that you're reading for info on the L series only.
After reading that, any other questions you have others will beable to answer
Cheers

Yeah it will work but stock up on gearboxes and take out life insurance, they don't last with that much power and it gets abit hairy sometimes when you have the ability to break traction on the wheels that are steering you at practically any speed.
It's not that hard to do, all the info is around here, spend a good few hours reading up on the forum.

its an awesome conversion.
i have EVERYTHING you need to do it here if you're keen. When i say everything, i mean everything. Custom radiator, chopped down wiring loom, 2.5 inch exhaust, low km import dual range gearbox, adapter plate, cut xmember, evrything!
no chassis mods involved. Its a pretty strait forward conversion.
cheers

Same size in capacity but the turbo is lower static compression to the NA EJ20.t35345 wrote:is the ej20t larger than the ej20 in size i mean
Most likely. I don't know much about these but I'm sure they have some sort of Factory BOV that's plumbed back into the air intake so not to trip out the ECU.t35345 wrote:and can you put a bov on a stock EJ20T
Hope this helps a bit.
Cheers
Bennie
LOL at the BOV question.
You can put shiny pod filters on them too.

they have a stock bov which makes a nice psht noise which is well than loud enuf. Otherwise youll need a semi or full plumb back bov.

EJ or EA?? If you've got the standard 1.8 litre motor in there its an EA and would be worth upgrading to the EJ in most people's opinion...Josho wrote:just having a read through here i'm looking at buying a wrx halfcut for my l series as yesterday after having a wee bit too much fun i discovered a hint of oil in the radiator car not over heating but not looking good:( think the ej might be dying,

2" would restrict it slightly as the stock exhaust on an RS is 2.25". At least it is as it comes off the dump pipe. But you will get away with it.
3" is absolute overkill - totally not needed unless you are modifying for big horsepower.

That is right on the money. A better/newer dump pipe is a good upgrade but you only need to go back as far as the flange on a standard motor.2" would restrict it slightly as the stock exhaust on an RS is 2.25". At least it is as it comes off the dump pipe. But you will get away with it.

The EJ20 turbo will fit an L series with out doing any cutting to chassis rails and that is a definite. No confusion about it. You do need the crossmember modded to suit the up pipe though.
Yep. I think some of the confusion might be exactly what needs cutting/welding and exactly what car is being talked about.
EJ20G into L series car;
Chassis rails = No modification required
Engine crossmember = Cut/weld slightly to clear turbo exhaust manifold OR swap for an engine crossmember from a EA82turbo L series (such as Vortex or RX Turbo) but these are abit rare these days.
EJ20G into MY series car;
Chassis rails = Cut/weld to widen slightly to clear the plastic engine timing covers
Engine crossmembers = Cut/weld slightly to clear turbo exhaust manifold OR swap for an engine crossmember from a EA81turbo MY series but these would be near impossible to find.
All this info is in the sticky thread about putting EJ engines into L or MY cars at the top of the Conversions section.
