hey lads,
long story short i need to replace my red MFI lines on my 88 escort rs turbo. luckily the guy i bought the car from gave me a spare inlet manifold with 4 of the 5 MFI lines attached..
Upon starting to replace them i have come into some confusion
1. my car has the "sandwich plate" between head and inlet manifold and injectors fit into that plate, where as the spare set up i have the injectors fit into the inlet manifold? maybe a turbo vs xr3i thing?
2. the MFI unit ends of the red plastic lines have different bends in them on the spare set ,mine are more straight where, as the spares almost bend 180 degrees in a semi circle ?
i am sure the lines will fit and work but can anybody clear up my confusion with the sandwich plate, as i have read many times people use these for EFI conversions yet mine is MFI and has one fitted? the car has lots of extras on it so maybe someone added it for some gain?

Xr3i and RST both use the sandwich plate that houses the injectors. No manifold came as standard with Injectors straight in - people have modified them to take injectors however (tho usually EFI, i see no reason/benefit to do it for K/KE-JET).

Do you have a pic of the manifold?

I "think" some of the RS1600i lines were routed slightly differently to 3i/RST to the metering unit but weren't so different that you couldn't make them fit..

that's a s1 rs turbo inlet not a s2 there is no green knock sensor either to the top right

haz87

^^What he said, I'd assumed it was an S2 manifold you were referring to

ahhhh thanks lads..
i had maybe 8 S2's and one S1 back in th early 90s back in england, they ran great so never had to fix them....just fit monster stereos like we all did haha i literaly have not seen a single one not seen one since 1999 and just found one locked in a shed for 7 yrs after being imported to oz in 2001. i snapped it up

dazbuster

so will the injectors i have spare ( in this S1 inlet manifold) work on my S2??

haz87

Yup injectors are the same. Tho i'd get them tested - even brand new getting a matched set/decent flow rate is hit and miss

car started after sitting for 7 yrs...then perished return hose sprayed fuel around and caught light from the dizzy...badly charred the mfi lines , luckily they didnt burn through
lucky i have 3 spare lines and the cold start line...just chasing cylinder 4 line,,none in australia at all

yes as said above but mechanical injectors especially ones of that age I wouldn't even consider using again, even if they spray correct the chances are they will leak when you have been out and the car is stood filling a cylinder with fuel and causing bad starting when warm.
for £130 for 4 brand new injectors I wouldn't contemplate using them again.
fit new and save yourself the headache later on.
