Hello, I posted before about what route to take for my 95 imported wagon, I decided to swap ecu and turbo, so I have collected td05 turbo, z4 ecu, yellows, fuel pump. At mo it's just got full decat and panel filter so can I get these fitted and drive it til I can afford a remap?
Any suggestions, will it be ok?

Cheers

i wouldnt recomend it mate you ecu will be have to be set up for the td05 and the fuel your could ever run it rich or lean.... u could do real damage.

The z4 ecu is set up for the td05. Its standard on saloon
Imports. I just dont know weather or not to add pump and
Injectors?

Thank you for your reply

ok then, but your air flow will be difrent to the flow the turbo needs. and i would put the fuel fillter on as u will probs run to rich.... i would save your money till u can afford a map put your mods on a day or 2 before u go to the map.. that way u dont ru the risk off doing damage. what would u rather have to fork out.. engine rebuild or a decent map?? you dont even have to go anywhere duncan @ tace dynamics will come to your house...

Not true , i have done 6 of these conversions in the last 2 years and the Z4 & 6k ecu's are designed to run a Td05 as std - so no issues at all.

but every engine is diff, u better off with a custom map for your car, albeit you can run off boost and be fine

You should add the pump as your oe one is 17 yrs old and whilst it might be working ,it may be a little tired so a new pump saves the worry about running lean.Regarding injectors if you think that you may add more mods in the future and go above 300 bhp then opt for 440 yellows.If you are happy with decat ,Z4,& td05 then the 380 cc greys will suffice.

The last td04 to td05 conversion I did was 3 days ago & instead of a Z4 we used a 6K ecu, which is off a version 2 sti.The car already had a walbro 255 fitted and I added some 440 phase 1 injectors.The car started up and ran 1.0 bar boost no probs ,just a quick run on the dyno next week and happy days.

So your telling me the air flow is the same as every map?? Hmm don't think so :s the Subaru engine is pretty temperamental to engine mods... I got that from torque development. What ever mod I.e turbos injectors air filters FMIC ecu. Has to be programmed to that ecu to run the risks out. Like I said z4 ecu might be for a td05 but it's not off that engine. The ecu will have to be programmed to that engine. Might run fine but u don't know what's happening in side do u??
Right or wrong??

Very true ,but a wrx saloon and a wrx wagon of the same year (1995) are damn near identical only the wagon has a smaller turbo(td04) compared to the saloon (td05).The wagon has a different ecu(6k),as it is classed as a sports tourer and is detuned to give 220 bhp opposed to the saloon's(Z4 ecu) 260 bhp. The compression ratio iirc is slightly lower on the wagon,which is why i put on the end of my last post that once the parts have been swapped then a trip on a dyno is worth doing to check all is well.

So ideally after the swap isnt the best idea to be using your car day to day till after a map

1 x Z4 ecu is no different to another Z4 ecu unless someone has opened it up and inserted a chip,etc.The car will only run to the parameters of the information the ecu is giving out,so if i put a z4 out of my mates car into anoter wrx saloon it will be no different to the oe Z4 and will still only achieve 0.8/0.9 bar boost.
The difference is when a ecu has been custom mapped for a car,as an example:when i wrote off my 99uk turbo running 316 bhp I took ALL the modded parts off and put them onto my 00 uk turbo & took the car back to bob rawle for a map tweak. Dispite both cars being identical with exactly the same mods my later car was running way to rich & after some adjustments made 324 bhp

Yes ,if your going from a td04 to a vf35 as the td04 ecu is mapped to fuel a td04 turbo.
A Z4 ecu is mapped to suit a td05 turbo,a wrx wagons ecu is detuned to give less power not the engine,which is why this is such a popular upgrade for early wrx wagon owners who want more power at minimal price,as it does away with the need to spend £400 for an apexi + £250 to map it,when a turbo & ecu can give you 40 bhp quite cheaply and not to big a risk to your engine.

iunderstand both points very well and am happy ive got some info, i completely understand that if you mod anthing you need a remap, but i was hoping that the 95 wrx import wagon and car was exactly the same bar the turbo and ecu so if swapped a cheap way to gain 40 bhp because 220 is useless, i was just wondering if swapping the ecu and turbo is ok or do i need to put the pump on aswell, i have theyellow injectors 440, but should i leave them till remap?

basically if you had the saloon wrx 95 260ps as standard would you have to remap it to add full decat and panel filter?

thanks again

ecu swap is ok but get it mapped if swapping injectors 100%. anyone on here will tell you that

lamby2k12

That's what I said as the question at 1st was do I need a remap after fitting ecu turbo pump an injectors..

Thanks again, what my question probably should have been not to cause confusion is which bits can i add without a remap, thanks

Is the 6K mappable or will it need a daughter board?? Thanks

I'm using the z4 not the 6k and going to fit it this week along with turbo.

6k is not mappable , so it wlll need a esl daughterboard.
