wireing loom

[mk3phill]

are the ecu/engine wireing looms the same for a motronic 4.4 and for a 2.5 10v??

[timbo_1975]

No.

the 2.5 10 is the only motor to use the fenix 5.1 system , which uses a map sensor, and just a temp sensor where the MAF would normally be.

The ISCV is also different from the bosch application, but it's still a 2-wire component.

The 10 valvers dont use a variable length intake manifold like the na 20v's do.

Does this help?

yer thats great man,... least i know ill have to swap complete engine looms now aswell

[timbo_1975]

Are you swapping t5 motor into the place of a 2.5 10v then?

[mk3phill]

not quite,but engine swap,.yes in near future. had some fun with my 10v 2.5 but its time to up the game,.. but the car as a whole is so clean i dont want to be rid of it tbh. i know i could just buy a T5 and be done with it but where's the fun in that if i can rebuild soemthing myself for no extra cost

[timbo_1975]

I wondered, as i have a totally mint '97 100k 2.5 10v S70 that I use day to day, and to find a similarly tidy T5 low miles would be probbaly nigh on impossible, so it had crossed my mind about dropping in a T5 motor when the time came, but the feasibility / botherment of the job kinda put me off... (if you do it, make some notes for future reference can you!)

Tim..

will do man,.. for me its just the next step really to the motor i really want. although i aint using a T5 im gonna build my own engine'ish
