@@OkiSubies actually i do have lots to ask i currently own a 2004 forester xt, i let a friend drive it and he broke the automatic transmission. Can another transmission jus bolt up to replace it or does the numbers on the transmission have to b the same ?
@@macneilbascombe6084 I would definitely try and keep the numbers on the transmission the same. But you can also look at AT Impreza’s because they Also use the same transmission
Swapping mines and I can’t tell you how much this has helped me. Almost ready to drop the motor back in! Just need to finish up the speed sensor wiring & reverse lights & source a few parts I’m missing and it should be ready to fire up!
@OkiSubies need to find the pin that makes the ecu into a manual one. Mines is a USDM 04 xt and I can’t find online for a pin out that says which one it is. Yours at 31:15 is that green one but my pins are different than yours.
@@Owensti there is a TID switch in yours with it being different, you might have to reflash your rom with a 5 speed rom🤔 Does yours idle up higher? The good thing with yours is that it is tunable, unlike the SF platform.
I am in the process of doing a similar setup. I took an EJ20k from a 97 Forester turbo and put it in a USDM 01 Forester. I already have a 5 speed so that part was pretty easy. I was screaming at the screen watching you guys try to figure out the wiring😂 I found it was a lot easier laying out two wiring diagrams and merging them. On my ECU (yellow 3 plug) there are two sets of pins on there for the neutral switch and TCM. The diagram shows which pins needs to be grounded if you are using auto or manual.
Also with my swap I cut the harness at the ECU and merged the two there. Under the hood I made cross connect extensions cables to go from the Forester's OEM body harness to the EJ20K's engine harness. It made it plug and play. The swap was actually easy. Not because I have done this swap before on an Impreza, but because the EJ20K requires less wires than my Forester currently has so there were a lot of things I didnt have to worry about hooking up. The only wire I had to add was a new wire for the MAF sensor since the 01's only had MAP sensors.
Im midway through doing this on a BH5 legacy twin turbo and have watched this video at least 5 times, its a great help i know the cars arnt exactly the same but gives me a good idea on where to look Thanks and great job 👍
Tip: Instead of tricking/powering the key interlock on the ignition, just remove the steering column surrounds, the interlock is a small solenoid box on the ignition you can remove it and then the ignition works as it should and will no longer hold the key. 5 minute just saves some hassle.
And as for the abs issue, if you swap a abs pump from a manual car it also solves a headache, after manual converting several phase 2 cars seems to be easiest option, opposed to trying to trick it all.
Thank you for the tips! Removing the solenoid sounds like a way better option and we will definitely check that out. We have also heard about using the manual pump and that would have been great to try but unfortunately we didn’t have any easily accessible. Thanks again for taking the time to share the info!
@@Jonny5ox speed sensor install is easy, use a 3 pin vss, one pin is ground, one is +12, wire the signal wire to the tcu signal wire that sends the signal to the cluster/ecu. If you don’t have a pinout for your tcu plug just use a multimeter and do a continuity test from the speed sensor pin on your ecu and probe the tcu plugs until your find it
@@MrTakeaswig thank you for the information, sounds fairly easy. I've been recently wiring peugeot 309 loom spliced into a citroen xm turbo loom. Japanese wiring got to be better and easier than french
I buy it just like it is. I also didn't know these came in autos for a forester sti. When they made this forester sti they should have shipped around 4000-7000 of them to the US
I'm curious, what do you guys do with the automatic transmissions? resell/throw away? roughly how much would you sell a forester sti automatic transmission package?
I have a 2005 Subaru Legacy GT, and did a conversion from Automatic to Manual transmission. Do you have a video on how to trick the ignition to get the key to come out and how to jumper the wire to get the car started? Does the computer have a ground for it to read manual?
Do you have a wiring diagram for the car harness plug to the gearbox for exactly which is the neutral position switch the reverse switch and the speed sensor
From which car was the 5 speed manual transmission obtained from I have a fully forged closed deck built engine with FP blue 1050 injectors bug eye WRX wagon with a 5 speed Impreza GC STi version 3-4 and I was wondering if I should go 6 speed swap as I’m scared that 5 speeds tend to break as most people say. For me it’s not about the extra gear but My point is is the GC STi version 3-4 5 speed reliable? Much love from kenya

Got the motor in & everything connected. I’m getting a no start. It cranks and cranks but doesn’t want to fire up. I know I’m getting spark & fuel. As well as the motor I know it’s good because it came out of my running and driving 06 Wrx.. what should I look for now.
They were backwards at first, I fixed it and it’s still not starting. Before I fixed it and left the fuel line disconnected I turned the key and fuel started dumping out so I know my fuel pump is working. I can also hear it priming
Manual swapped my usdm na 99 forester with a 05 na fozzy mt and did real similar stuff with the neutral position switch and reverse lights and unplug the tcm. Still need to ground the manual identification pin but no one has a reference for the pins on my harness (everyone has different connectors than me). It’s been running fine but every couple of days it dies when I throw it in nuetral with a code about the p1507 related to the nuetral switch I wired just like yours. Gonna find that pin and try again

I have the same SF5 forester but not the STI model. A 1999 version. I’m experiencing some boost cuts that are on and off causing on and off power whenever I hit about 3500 rpm in 3rd, 4th and 5th gears. What could be the issue?
Would it be possible to delete the ABS system? I only ask because the modules will eventually go bad causing the ABS light to light up anyway… or is it just simply better to have the ABS system intact other then for obvious reasons like Oki roads mixed with rain
Definitely possible to delete the system, if the system fails the brakes would act just like if it wasn’t there so I wouldn’t worry about it too much. You could probably even get a GC8 Type RA brake system and delete it with oem parts.
There are two wires on the harness that you have to wire to the 5 speed reverse light switch and the speedometer was oem 3 wire sensor. Both are explained in the video🙂👍🏻
@@wubgee3311 You would have to get a gauge cluster from a 2 wire car and re pin it. Two wire speed sensor goes to the cluster and the cluster sends the speed sensor voltage signal to the ECU so without the cluster it is not possible.

@@OkiSubiesi brought a 2001 subaru forester s/tb that had a transmission swap and the transmission has a 2 wire vss out of a older model subaru i think and the harness from car ej205 is 3 wire plug and the speedometor is not working and cel light on 4000rpm limit i was really just seing if there is a way i could get it working cheaply without paying 600 for a vss pro harness from i wire wich uses the abs delivered to new zealand
That is a loaded question. It's all on the driver and abuse. As long as you are not clutch dumping and FFS a 5 speed, it will hold an indefinite amount of torque.
We have done legacy engines in GC8’s and have done a good amount of wiring on the Legacy platform. The biggest challenge that you will run into is the immobilized system. What engine do you plan on swapping?
@@officaldjflo those swaps are a lot more straightforward depending on what engine you have. With the EJ platform the ECU, Harness and heads are the most important to look into. Many times you can swap the long block from another engine if the long block shares the same heads.
