Here's a question.
When putting an NA EJ20 into a non lifted L series sedan, does the exhaust that came with the engine (impreza or something) clear the underbody?
I think a lot of people put EJs into cars with lift kits which gives you plenty of clearance but just wondering about stock height cars.
Thanks

Gday tommo, i've just fitted a naturally aspirated ej into an l series that hasnt been lifted, engine and exhausts fit in with no problems.

The EJ header pipe will clear the underbody as long as you don't put really thick wedges under the engine mounts. 9mm works for me, 12mm was too thick. The rest of the exhaust, i.e. cat-back, must be L series with a slight modification/

Not sure what you mean about wedges under the engine mounts Dane, care to ellaborate? And yeah, it's just the header and cat I was wondering about.
Thanks.

The EJ engine crossmember has a flatter angle on both sides where the engine mounts sit. When you sit them on an EA crossmember they are at a greater angle which can eventually lead to premature breakage of the mounts (they are only rubber and usually quite old to start with). It's a good idea to make small triangular wedges to bring it closer to the original angle. A few people have posted photos of what they've done. It's not entirely required but a good idea. You do need to space the mounts up slightly anyway otherwise the bellhousing hits the crossmember slightly.

Three bits of 50x3 flat tacked together, so 9 mm thick at the thick end. My previous attempt used four pieces, and that pulled the header up too much and made it touch the crossmember.

I see now. Thanks alot guys, very helpful!

On my trial fit of an EA82T onto an MY crossmember I considered the wedges, for amoment, then simply tightened the nuts up and pulled the EA82 engine mount into place. Does this also work in EJ engine applications. Thinkinmg not if it is 9mm you dealing with

On another topic,

CHOOSING DONOR CAR FOR CONVERSION

If it has been said before in THIS thread, my apologies.

Thinking is along the lines of buying donor car, not just bits.

IF the receiver is MY, considering you may also do brake upgrade, I have read it is best fit that Impreza suspension is used with the brake upgrade on MY, so unless you are going something EJ not available Impreza, you go look for a four wheel disc braked Imp. Some early models had drum rear

You can but some would say that the engine mounts will fail fairly quickly?
My ute has done well over 100 000km with conversion in it (ej20t in brumby)
without wedges. I have only seen one gone in that time due to oil/grease on it also when i killed the gearbox with a hard launch and hard into 2nd.

So i think its more due to normal wear and tear

For some reason they (the EJ mounts) work better in the MY Series than the L Series.. I have seen many in the MY Series without them. I also have seen then without them in the L Series and they have VERY large cracks in the rubber.. sure this can be from age but you can really see the stress the mount is under when it's in an L. I'm sure with the amount of conversions done, there would be plenty of pics around.

hi im new just a quick one i have l wagon will a ej20tt bolt straight up to my ea box??

quick answer nope

you need an adaptor plate and alot of other bits to make it work

a good read

why am I in here ??

need to learn ECU pin outs for 1986 EJ16 in order to know what needs to be connected to do spark only for a dedicated LPG application. Found there are just some holes at rear of RHS camshaft no dizzy drive slot
do not need idle speed
need egr control
need crank angle sensor
do these also have cam angle sensor and knock sensor?
need coil connected

1986? 1996?

EJ16s and EJ18s don't have a cam sensor or a knock sensor. Don't think they had any ECU control of the EGR gear either.

You'll struggle to find pin outs. When I was looking, there were a couple of manuals floating around the net, but nothing that really matched AUDM hardware.

Dane.

First of all, where did you get this motor and what car did it come from?

God is right above concerning early model EJ16 and 18's, but later models (which were designed for economy) would have sequential fuel injection and thus would need a cam sensor.

Basically you will just want to use the loom as is, just unplug the fuel injectors and let the ECU pretend its still doing its job, even though there is no fuel.

You never know, you may wish to run petrol later on.

A search on google got me this

apparently they use the same wiring ???

I don't think so

still looking

Actually, i think this may only apply to single point fuel injected models.

Sorry, meant to post this earlier but got distracted by something shiny (*cough* Gran Turismo 5 *cough*)

This is everything I have from when I was doing my EJ18 conversion, I was told the EJ16 was the same also.

I have most of them in high resolution if you need it.

Jordan ! You've moved again?

Thanks guys I shall have a look in time at the links.Hey even my 86 4GLTA ECU 3 plugger has some EGR control, well it is suppose to not operate below a certain temp or work above a certain speed. It does not have these limits - works all the time.

The donk came out of a crashed Impreza 1996 under yella oil cap - got the loom and ECU expertly removed by Damo666 and donated to a good home

Nope, all (four?) the Australian MPFI EJ16/18s I've looked at have been like this.
