I wanna do single turbo conversion properly and still have the twin turbo intake manifold on. does a v3 intake manifold bolt onto a ej20h? as im also having problems with getting it too start due too wrong ignition setup as i need wasted spark setup
-
Would anyone know where to find the full pinouts for a v1/2 WRX ECU? I converted too a single turbo setup and my car isnt starting at the moment as im running an adapter to run a V3 ECU but have a couple issues as im unsure of what wiring needs to be done under the bonnet so the map sensor and stuff works with the new v3 ECU. SInce im having issues i was deciding to just go to a V1/2 ECU and repinning it too that as that way I wouldnt have to change too wasted spark setup ect as I want this driving asap without having too tamper half the bloody engine again.
Ive already wired in the 3 pin air flow metre, got adapter made to fit a v3 ECU and got matching AFM to the ecu but still wont start.
engine sparks, cranks and gets fuel but just doesnt turn over.
its the BG5A model with the old ej20h so its the harder conversion too take on
-
Also i have a electronic boost controller T pieced into the turbo and wastegate actuator so how would I connect the BCS too this?
-
I don't have the plastic stock pipe as shown in your photo above. I have a custom metal pipe which doesn't have all the inlets as the stock one has.
-
intake pipe? As in connected to the pod filter? I dont think there is any more free ports in my intake manifold especially not as small as the hoses in the bbod

I have recently converted my EJ20H twin turbo engine to a single turbo setup.
I was up to the BBOD and I have set it up exactly like this in the photo provided.
I was wondering if this was the correct way to modify the BBOD for the single turbo conversion and if it is, what port do I connect the manifold pressure too?
I got a adapter made to fit my 4plug to 3 plug v3/4 WRX ecu and have also got a matching purple AFM.
Last things i have to do now is wire up the 3 pin plug to fit in the purple AFM and this BBOD.
Any help would be much appreciated.
-
the automotive sparky making me the adapater said the only thing i might have to change is the plug to the AFM as the purple and blue afm have different plugs. but other than that he told me everything is matched up at the ECU to do its thing.
For now ill install the V3 WRX ECU, purple AFM and see where that takes me.
It looks like the earthing has already been mofified in the engine bay but if I still have problems I will just get a call out auto sparky who said he could finish it off if i needed.

And wouldnt having a lower compression ratio engine compared to the compression on the ECU be better as lower compression is meant to handle more boost?
ANd thats the reason I dont want to change to 6S ecu as I dont want to change injectors which is a very annoying job rather just easily install the ecu and afm and be away,.
-
I have already bought the 2S and getting adapter sent to me already so I cant really get STI ECU now maybe further in the future.
Im just sticking to 2S ECU with the grey injectors as the adapter will do most of the hard work for me. WIth this setup im guessing I have to use the purple AFM then?
Would I have to change anything else when ive installed the new ECU and AFM?
I already have a after market boost controller on the vf29 but its just on stock 10psi
-
put it the way it was, jump started and was fine, think the DPS being connected muddled with something, just waiting on ECU to arrive now

I have acquired a 2s ECU along with a adapter so connect the 4 plug into the 3 plug 2s ECU. But apparently the compression ratio on the ej20g it came from has compression of 8:1 and the ej20h I have now has compression 9:1 so would there be an issue? It's single turbo converted with a VF29 but don't know if the ecu would be agressive enough as its non Sti

Sorry a lack of fuel was a bad description as a bad fuel pump usually means the engine doesn't even crank. My engine is cranking and making a clicking sound but not wanting to start.
-
I was told by someone to connect the two sides of the differential pressure sensor into a T piece then connect it into the intake manifold.
I did this then the car wouldn't start. Sounds like starter motor and battery etc are fine but kind of a lack of fuel? but not sure its fuel pump as it started completely fine everytime before I connected the stupid thing. Anyways I put everything back to how it was before and I still have the problem so im quite stumped. Havent even taken it for a drive since so I have no idea what it is.
Any help would be much appreciated.

I found a 2S ECU out of a standard WRX version 3 which I am getting an adapter made to plug and play and I was told that the version 3/4 run blue afm and greys so could anyone clear this up?
-
okay cool cause im just having a little difficulty trying to find what ECU code is out of the V3/4 WRX.
If v3/4 is 97-98 then the Z4 ECU must be a v1/2.
But I was told 95-96 are the v3/4?
If thats correct then the V3/4 ECUs must be these ones right?
Classic import- (saloon) 97-98
IS ECU code = 440cc injectors, 280ps VF22 turbo
6S ECU code = 440cc injectors, 300ps VF23 turbo
75 ECU code = 440cc injectors, 280ps VF24 turbo
But I was told standard v3/4 WRX ECU's run on grey injectors and blue AFM but the list above says they run on 440cc injectors which are yellows?
-
Thanks heaps Joker!
I found this on here
Z4 - 1995/1996 WRX – SAME AS SC- 12.7PSI (0.9BAR), DROPPING TO 11.7PSI (0.8BAR) @ 6600RPM
- FUEL CUT 15.65PSI (1.08BAR) - 260PS (256 BHP) – 7250RPM
Does this mean the Z4 ECU is a standard WRX ECU out of a V3/4?
-
Hey when i connected DPS into intake manifold car wouldnt start. Where abouts in the intake manifold do I conect it too because theres 4 different holes on the manifold.
-
I am looking for a standard WRX ECU out of a v3/4 as I need one for my single turbo conversion on my ej20h and was wondering what code or name they had. I am aware of 6k and Z4 but I'm 99% sure they are STI.
Need a standard v3/4 WRX one as I am keeping grey injectors and blue AFM .
Any help would be much appreciated.

Alsweet, will replace and clean the IACV and see where that takes me. also will reconnect DPS into intake manifold.
-
Do you think it could possibly be coolant temp sensor as my temp gauge on my dashboard takes a unusually long time to rise up to normal temp.
-
Engine doesn't really want to die while changing gear just as I take it out of gear it bounces around but doesn't want to stall. Only does that on start up.
I'll clean IACV tomorrow and reconnect the pressure sensor and see if it makes an improvement.
But I'm more then sure that it's not a boost leak as I've checked most of the things you just said but I could be wrong.
-
I'm not getting any Codes for IACV and after I give a couple revs for a minute or two it idles at 800rpm and sits fine. Just is weird on start up and when changing out of gears.
Where are possible hoses that are prone or known for leaking ?
-
Could the ECU be sending wrong readings to the engine causing the idle? Because I've checked all hoses and don't think it's s boost leak
-
Awesome, thanks heaps . Could this be the reason of my problems ? Car wanting too stall on start up etc .

Does a V3 intake manifold bolt onto EJ20H?
in Legacy & Outback

Am running a v3 ecu non Sti it is a 2s out of GF8 .
but sweet thanks is it just straight bolt? Any mods needed ?
