I recently put a thread up but yet to get the answers I need. There must be someone on here who knows.

Please please please try help me I don’t know where else I can find the
help or answers I need and im getting desperate now.

The problem I have Is I have just fitted a 1995 Uk Turbo 2000 engine into my 1995 WRX and it still has the standard jap spec WRX ECU.
Is this Turbo 2000 engine going to work in my WRX or not.
If not what is needed to put this right and make it work.

not 100% but i think you may need a uk ecu instead of the wrx jap spec..it will also need to be mapped to ensure every thing is correct ie air/fuel... ect.. also i think the wrx (jap) ecu will be mapped to run on higher octane fuel to the uk spec ecu

Could i not just use Super plus and use the Jap ecu or is the still gonna need mapping to work correct with the new engine.

Who could i get to re map a standard wrx ecu or is it even possible.

I dont think you can get the wrx ecu remapped, I think you need an esl board for it.

simon at jolly green monster is the man for that.

but at the same time im fairly sure you will need to change the ecu to match the engine so the UK ecu will be needed. but once again if you want to remap that you will still need the esl board. as the Ekutek maps are only for version 5 onwards, I think!

why dont you take the car to a reputable subaru mechanic. the fact that you have put a uk engine into a jap spec car would suggest the ecu will not work properly. pay some money to someone who knows what they are doing. dont rely on replies from here you could get 10 different answers from 10 different people. it is very hard to diagnose whether a car will do something or not when there are so many factors to take into consideration. while some of the people on here are good they are not that good. the only way to really check is to take it to a subaru specialist garage and pay your money.

I assume you are still running a TD05 turbo and 380cc injectors? If so, I think it will be a Z4 ECU and should work fine with the UK engine. Just put SUL in to be on the safe side.

Its not going to blow up if you turn the key, so there's nothing to lose in trying it.

I would love to do that but as always it a money issue. Having lost my job this year I cant afford to keep chucking money at it.
I blew the engine over a year ago and I have been trying to get it into a work state for as little as possible so I can sell it. I desperately need the money from selling it if I can so I cant spend money getting it looked at and no one is going to buy it like this.

The car runs but a little rough. Almost feels like it needs a new MAF which i thought was the problem until i found it was a uk engine.
Seeing as I have put everything from my wrx engine onto the uk one except for the injectors could this make it run rough

The real question is why it blew last year. Chances are that if you run it as it was it will do the same.

I would be putting vpower plus octane booster to make it ad safe as possible if you can't afford to remap it.

a jap ecu will run a uk car the same as a uk ecu will run a jap car, i myself run a uk ecu in my car because i couldn't get a chip socket in time so ended up running a uk ecu,
as has been said before there is a problem elsewhere with the car.

[quote=dynamix;9301554]The real question is why it blew last year. Chances are that if you run it as it was it will do the same.

It blew after having a Power Fc fitted and the guys who mapped rasied boost to 1.5Bar. And me trusting in a tunning company before doing my home work resulted in a piston melting.

So really there shouldnt be a problem running it in my car and i should try and find if something is at fault.

Connected the 2 black plugs under the dash and its givving the error code for the MAF so guess thats a start

my94wrx

iTrader: (4)

its giving the fault code for the MAF, have you checked the wiring to the maf and the, wiring at the ecu end of the loom?

chris wrx 95

Someone has just said something along the lines of.

You need to swap the cam and crank sensor pin-outs around.

Whats this about and is it something i need to do

Chris, as per reply to your pm, and as bigsinky has already suggested, the only way you're likely to get an accurate idea what's what with this engine is to have it looked at properly. We have no idea, for example, whether there was something wrong with the replacement or whether it's been modified in any way - in a manner that stops it running correctly once in your car.

We also have no idea whether as Duncan questions, there's an underlying problem with a sensor or the ECU that's going to cook your new engine if you get it running right.

The money thing's a p*sser but the bottom line is that sitting here pleading with us all to give you a miracle cure is likely to be wasting both your time and ours. How many threads have you started now? If you didn't get an authoritative answer after the first couple, it's unlikely that two or three more will make much difference.

The only way issues like that are going to get properly evaluated is someone who knows has a look under your bonnet. What's worse, being unable to sell the car in its current state, or getting it sorted?

who said that??? that is only need for running import ecus on later model subaru`s ie 97/98 models

It may have been me chris was referring to (I posted in someone else's thread).

Are we saying that a MY93-96 Ph.1 JDM 4-plug ECU won't work in a MY94-96 UK car at all (whether those pins are swapped around or not)?

This is news to me, sorry.

my94wrx

iTrader: (4)

joz, first things first, they are 4 plug not 3!
i am referring to his quote of swapping crank/cam wires around this is not needed in phase1/2 cars and only required in later models as per my post, where did i say about phase1/2 uk/jdm ecus not being interchangeable?

chris wrx 95

iTrader: (1)

Ok so my local garage wont touch the car as they say they don’t know enough about them to even start looking.
And the local Subaru dealer said they don’t know if it will work or not and after them diagnosing my melted piston as a broken turbo I don’t hold much hope for them.
So who or where do I take it to try sort it

dynamix

4 plug ecu in 92-96 and UK / JDM will swap but the JDM ecu's run very aggressive timing for jap spec fuel - even more aggressive if chipped.

Was it just swapping to apexi and running 1.5 bar that melted it or was there a fueling issue or a.n.other issue.

I would be very temped to just get a UK ecu from an early classic and run as is until you have more money to get it looked at properly before trying to increase performance. An early uk ecu will not cost you much - circa £70. I have one sitting here.

At least then you will be on the road and hopefully as safe as it can be (assuming no underlying issues).

Would also be a good idea to get the fueling/det checked over by a specialist to make sure all running safe.

The last thing you want is to be trying to get top performance from it if you can't afford for anyone to even look at it let alone map it properly.

chris wrx 95

iTrader: (1)

Im not to sure what caused it to be honest but 1.5bar on standard internals cant have helped.

Im not bothered about performance at all I just want it running so if changing the ecu I s a good start then ill try it.

Car is currently running but with a faulty maf. I cleaned it with contact cleaner and it made a fair difference but still needs a new one. Apart from that it runs ok just smells a bit rich now

Chris,

Sorry about the money thing. I was going to chirp in that buying the car is the easy bit, the upkeep is the hard part but i guess you know that now. Being in Northern Ireland we have a bit of a captive market here and i have been so fortunate to get a superb mechanic who does the vast majority of his work on subarus. having said that there are a fair few people on here who will be able to give you a steer in the right direction to a good mechanic in the reading area. the fact that the subaru dealer hasn't a clue doesn't surprise me as they tend to deal in oem parts and regular subaru services. ECUs and engine swops tend to be a bit specialised and require a competent master technician, who is familiar about how and engine works (air, fuel, timing, compression) as well as a fair knowledge in mapping techniques.

hope you do get this sorted. a sh1tty position to be in and as you say you dont want to be throwing good money after bad.

Guys, guys (lol) I know a MY93-96 is a 4-plug - it was just a typo!!!

bigsinky

^^^^^^^^^^be honest joz, you didn't know. your as thick as two short planks aren't you *nods head

joz8968

iTrader: (13)

That was just a rushed typo on my part, sorry.

I've amended my post to read 4-plug.


Chill - I'm not saying you are.

Just that I didn't know that you DON'T swap the crank and cam sensors on a MY93-96 (I thought it was required) - that was all my post was asking (although I naturally confused things by inadvertently typing bloody 3-plug instead of 4 )

So the swapping is only for a MY97/98 right?

joz8968

iTrader: (13)

You being serious? Flippin' 'eck I made a genuine typo for chrissake! You don't know me, so may I kindly ask you to f**k off.

(BTW I have a MY93 and have previously accessed my ECU, etc. )

The worst thing of all mate is that I have owned the car for just over 5 years now. It had 47k and full Subaru service history from when it come into the country. I had a full respray and the interior was absolutely mint.
It had sensible mods to just a Hks exhaust and headers, Bailey dump valve and an Apexi induction kit. Until I wanted more power and got the Power Fc fitted and that’s where it all went wrong.
Subaru said pretty much what you said that they are more of a service side for standard cars and don’t really no much about moded ones and so on.

On the upside I was eating my lunch lol when I though hang on that fuel has been in the tank for overt a year now. Emptied the lot out and half filled with Shells Vpower Only half just in case it died and all seems fine. Fingers crossed it stays that way. Now time to wash all the green muck off from a year of parking up on the drive.

As far as I know you should be fine, I dont think there is any difference in compression, the cams may be a bit softer but its doubtful they will cause you any harm.

But you could put the std wrx cams back in.

All seems ok since i filled the tank with Shell Vpower
