what would you do in my position?
i have 95 wrx wagon with 3b ecu and td04 turbo with full decat system and panel filter.
i will be buying tommorow a walbro fuel pump. thats fine but would you then purchase a z4 ecu and a td05 turbo, will the ecu just plug in and work or will there be complications?
or would you just get it mapped as it is with one of those daughter boards?

thanks for all the input, im just not sure which is the best route and any advice will be geately appretiated.

cheers

 

get it mapped mate,

 

cheers addi monster, do you mean map it on the 3b ecu with the td04?

cheers

 

i would bin the td04 for the td05 add a 255 walbro and pop some 440cc injectors in and a bigger top mount and you will be around 330-340bhp with a map , you will need the esl board or a simtek ect ect

 

To begin with I would go td05 and a td05 ecu like z4 and get it checked.

Then when bored get remapped or fmic, 440cc injectors and remap.

so you say i can just plug and play the td05 and z4 without any complications?
when you say checked what do you mean?

cheers

 

Yes

Dyno run on a decent rr that checks fueling or a mapper to check it with detcans and wideband.

 

Thank you very much for the advice
