Right brought a 88 spec rs turbo, which is completely standard. Last week i whipped the engine out and freshened it up, new clutch and so on... Now the turbo oil seal is leaking. Cant be valve stems as the head has been rebuilt, and the oil seems to be in the pipes and down pipe. I copied a breather system set up on here yesterday and that hasn't made a difference.
Question is i have a brand new fully rebuilt FRST engine and loom do i fit this and do away with the MFI? My RS even has working ABS which i want to rip out as well.

Keep reading threads on here and im getting all sorts going through my head lol

 

If the turbo oil seal is leaking... then it's the turbo oil seal?! lol
Doing away with the MFI is a good move especially if you want more power, fitting the Fiesta ECU and loom is not such a good idea, it's almost as unreliable and limiting as MFI these days.
I would use your best engine and then go standalone management, save a lot of time and money IME.

 

100% as above, mfi is a nightmare when it goes wrong. Don't bother trying to go cossie management either, it's a ball ache.

Invest I some thing a lot newer and you will see the rewards.
