View Full Version : Has anyone done a pre 97-98 installation of a EJ20T?

I'm sure someone has done this swap but I was wondering if it would be easier or harder to do? being that there are a few more mechanical parts and a few less electronic (ie the dash gauges, speedo and tach). Does anyone know? All help is appreciated.
I am trying to decide between the kit and new motor or the EJ20T conversion. Please help.

wow you sure seem to start alot of threads
calm down

obd-2 started in 96 .. yes there are less wires and lower emmision standards.. but there are also things like cable speedometers to deal with

my other 1/2 has an ej20t in his 1995 L AWD

he did a full swap managed by Autronic.
Car is an SCCA Club Rally Open Class car.

tons of work
lots of sweat and tears...

and $$$.... but it's done :D
and it's fast :D

yeah my posts seem to stay around for a while and so they build up and make me look like I'm flipping out. Why would the cable speedo be a problem? Please explain.
Thanks, Micah
Did your friend keep his gauge cluster working or did he get a rally computer (all digital)?

I transplanted an STI IV into a '95 L, and used the gastank and rear-crossmember from a '99, wiring harness from a '99 and interior from a 2000!

Runs great!

I checked it out and it looks good!! It was a little bit of help.
does anyone have any tips or advice to give for doing a pre 97 WRX swap?
Thanks, Micah

tips? advice?

save up and be prepared to spend at least $7k to do it right.

does anyone know if the EJ20 install is easier on the older (93-96) imprezas? Please help
Thanks, Micah

Easier? It's the same car clear up to 2001. Now, it can be easier if you do away with the emissions controls and have fewer wires to deal with. Pros and cons for each.

Cable speedo was mentioned because the older imprezas used a mechanical speedometer. The cable goes to the speedo and the gauge cluster sends the speed signal to the ECU. The newer imprezas use an electrical speedometer and the speed signal splits from the tranny and goes to the ECU and the gauge cluster. This will only be a concern if you swap in a newer transmission or if you use a newer factory ECU.

The electronic speed sensor might fit into the older transmissions and the ECU might be able to source the signal from the gauge cluster, but it hasn't been verified. I might check that once I get my swap going or I might just swap in the MY02 gauge cluster.

that's the sort of stuff that I was wondering would make it easier, the mechanical gauges and all. Let me know what happpens.

keeping it alive....anyone know anything about the mechanical gauges?

I know the ECU expects 0-5v from the vehicle speed sensor for both mechanical and electrical... Not sure if the ramp-up rate is the same as neither FSM gives the appropriate pulses that I have seen.

I'm kind of curious if the mechanical speed sensor will bolt up to the newer electronic vehicle speed sensor locations. If so, then we can keep the older gauges and bolt in the newer trannies. By doing so, the install becomes modular where we can do the tranny/rear diff on one weekend.

There are more and more shops out there doing swaps now so if anyone gets in over their heads (as it sounds like some people might be) give a reputable shop a call, I am sure most would be happy to help out ... I would say who I would deal with but I think that is against NASIOC rules ... hmmm

I had my swap parts sourced by, and the labor performed by Lachute Subaru. Nothing but good things to say about the entire experience. I just wish it was a little closer! ;)

Hi, Mark. Keeping busy?:lol: I'll email you, I have a question for your or Yves or whomever about getting a JDM STi instrument cluster to work in my car.

I can attest to Trent's satisfaction of Lachute's work. :D

IF I move back home to SE MI (knocks on wood and says a lil' prayer to the man upstairs) I'll be "vacationing" in Quebec sometime this summer. :devil:

how much does lachute charge for just splicing and soldering the harnesses? that is if I sent the two harnesses up there.
Thanks, Micah

No idea what they'd charge. I believe that the shop labor rate is $50/hr. Plus any parts they need to replace in the harness (i.e. connectors, etc.). No idea how long it takes to get the harness sorted, though.

Email / call them and find out.

Why would you have a problem if using a newer ECU? Are you talking about just the splicing and soldering of the harness?

I'm figuring that if the new ECU get's only one signal of engine speed (from tranny) and the older only one (from the gauges) why would ther be a problem?

Click the submit button about 3 times fewer.

You could have a problem using a newer ecu and an older tranny because the signal must be tapped off the gauge cluster. While both ECU's expect a 0-5v signal, I am not sure if the pulses are the same between sensors.
