I Have put a turbo in my xr2i 92 mod 1,6 and its not a original frst.
The turbo I used is from a wrecked escort rs turbo but the problem is when i get 0,4 bar it wont pull any more and it dosent rev above 3500 rpm . If i have 0.3-0.2 bar its running okay but its not accelerating so much better. Could the compression get to high since the engine is original non turbo ore could it be the ECU? Any ideas

Have you used a FRST ECU and wiring loom ?

[fordrs turbo]

no everything is original

[scotty_boy]

so what have you done? you put a erst manifold and turbo onto your XR2i block and ran boost pipes to the inlet?

if so thats the funniest thing iv heard all day.

no everything is original

Theres your problem then .............

[fordrs turbo]

yes that is all i have done. Its hard to get hold on a frst in norway because there aint any.
But why is it running okay under 0.4 bar and is the ecu the only differens between frst and xr2i.
Thanks for all replies

[fordrs turbo]

so if i change the ecu it would run like a frst?

[Fezzy Turbo]

you are now using forced induction (turbo) thats why it could be restricting the revs. Your 2i ECU cant cope.

You would need a FRST ECU and loom .... then all the sensors ...... or you could use cosworth ECU, but again you would need the loom and sensors.

So where can i buy that for a nice price and is that the only difference between the frst and xr2i

Someone might be able to send you a loom for the right price

How you plan to deal with commpresion ratio? Haynes says " C/R of 1.6 engine (XR2i) is 9,75:1 C/R. FRST C/R is lower - 8.0:1!"

Well I can get a custom made head gasket which is thicker.
Could the compression be the problem why it wont run with 0,4 bar ore higher becaus the compression makes the fuel ignite by it self

[fiesta boy]

the fiesta rst uses forced induction and flat top pistons xr2i's dont
frst have diffrent pistons and blocks for the oil return
the cam pully is also diffrent and alters the timing
frst use ofab .early frst useing the webber type map sencor
and late ones run ofac useing fors own map sencor
both managmet types are diffrent from the xr2i 8v system as soon as your car reads more then expected amount of pressure it dosent know what to do


options are get an erst block mate ito your 2i head use a erst cam pully and import frst managment cossworth managment or buy custom aftermarket item such as omex
