apart from the obvious turbo, how similar are these two engines? if at all.... i.e is it possible to use the exhaust amnifold+ turbo off an rs turbo, aswell as other components on the xr2i? ant replies welcomed!

[Traser]

bttt someone must no!

[jayrs]

lots

rs has that differs from 2i.

different steering rack
different ball joints
shorter shocks and stiffer springs
wheel aliment
exhust
wheels
opening rear windows
green trim in bumpers and along both sides
turbo engine and components , i.e rad, spark plugs etc
ecu
interior
front bumper ( looks the same but rs has a small cut out for fan)
bonnet
gearbox
engine mounts
rear spolier
cant remeber if the 2i has a rear anti roll bar

got a feeling i have missed something

what ya up to then, making 1 from a 2i?

[andyhardy]

The engines aren't completely different - the heads are the same IIRC.

Camshafts are different.

Fuel rail is same - think injectors and fuel pump are the same, fuel pressure regulator is the same.

Gearbox is the same, clutch is different (FRST is thicker plated) and the bottom end's are different (FRST is lower comp).

Of course manifold and turbo itself are different as are the management that actually runs them.

Have a look at Project's website - he's got loads of info. on engine conversions and swapping of management etc.

Cheers,

Andy

na thats true, but the block is the same as 2i, pistons and conrods are same as ERST and as above, but gearbox is different, only the final drive but you know what i mean. its got the same final drive as the ERST but without the LSD

pump and injectors are the same yeah.

oh and if anyone tell you the shell is different as the turbo shell is stonger there full of $hit! the shells are all the same.

[FezzR]

the block is not the same there are some suttle differences but none that cant be added to a 2i block to my knowledge

like oil return from the turbo

i know the block has a oil return for the turbo added but this is only a modification to the 2i block, thats it.
thrust me.

you could use the 2i block and have the oil return via the sump like the turbo technics converstions on the xr2, not that i would go for that myself.
but its the bare block thats the same, i think the crank is the same too but cant remember now.
anway check this out, ford manual dont lie.


if theres more suttle differences what are they please?

[cfoster]

how different are the looms?? Is it a matter of a different ECU plugged in and a couple more wires, or are they completely different?

Chris

[jayrs]

well the difference between a OFAC and OFAB looms are a few wires, as for the 2i one, im not sure, depending on the ecu you were going to use OFAB or OFAC it could be the same sort of thing.
of course you would have to wire in the wires for the boost control valve, but TBH its prob not worth pi$$ing about with as you would need a rs loom to go by to make sure, so you may as well fit one.
apart from a few sensors, the rest is the same,like E-dis module etc.

when i listed above, i put engine and componats differ, there are things like map sensor, air intake sensor, thermo rad fan switch etc, but hey, someone else has got to post too, lol

i dont mean to sound a "know it all" but i know what i on about and since having trouble many years ago with ball joints as they differ ( 3 types on mk3)i found the RS to have many parts for that model and that model only and over the years have found these difference through experance, asking questions/calling ford tec and getting ford manual for the RS fiesta etc to make my car be the best it can as i see so many FRST and 2i's with wrong bits on them like ball joints.
i had to wait 2 years for a steering rack for my car once because they differ and didnt make them anymore.
2 years! thats taking the pi$$, oh and it was £120 at the time

[jayrs]

oh yeah, uk models had Fiesta rs turbo on the back, LHD models had just Fiesta turbo
in direct to you question, no you cant use the turbo and manifold on a basic 2i engine.
you could keep the block and the head ( bear)
but you would need to fit a rs cam shaft in head
and if you wanted to go the "oil return in sump" route you could use the 2i block but you would need the rs turbo pistons etc
its poss cheaper to do it this way but if you can pick up a good FRST egnine for good money, then get that

[SimonT]

Moving on from the engine side of things:

What if be worth replacing a XR2i (16v) suspension components with FRST?

[jayrs]

your prob better off going for a after market kit really mate.
but the rear shocks on a stanard FRST are 25mm shorter with revised damping rate compared to the 2i ones
the fronts are the same as far as i know but the sprins are different also as there stiffer and a little lower

[SimonT]

OK I understand that. thanks

What about Steering rack, lower arms, front/rear ARB's etc

Are the turbo items the same as the 16v 2i? If not whats the differences.

ta

ST

[andyhardy]

I was always under the impression that the turbo was the only one with a rear arb - but perhaps the 2i's do too?

[jayrs]

thats right andy it is.
the fiesat turbo has a quick rack ( shorter lock to lock)
the 2i dont have a rear anti roll bar, the front lower ball joints are set 10mm out and 10mm back.
if your FRST has a lower arm with 2 rivets holding the ball jointin, its wrong!.

how ever, the ball joins are for different cars, 1 is for all fiestas inc 2i ( unsure about 1.8 2i)
1 is for the RS turbo
and the other is for fiestas with power steering.

[Traser]

rite cheers for all of that.... basicaly looking for a college project, originaly thinking of rs escort van.... then dropping the rs turbo into a mk 2 fez, but insurance has taken them out of the picture as i will only be 18 with 1yr ncb when i finish it..... i was considering putting the rs turbo on the xr, anybody know if its done often? cheers, steve

[jayrs]

what you mean? converting a xr2i to rs turbo?

if your doing a project at collage, how about a 4x4 cossie lump in a mk 2! lol

na for real, i bet a 2L mondeo zetec lump in a mk2 xr2 would shift., or a mk5/6 RS2000 lump

[SimonT]

I've got a 16v 2i and its got a rear ARB and is only 2.4 turns lock to lock on the steering if I remember right.

Lowering a car gives more negative camber anyway so I take it if you have a lowered car there is no need for a FRST suspension setup?

[SimonT]

and yes a 2.0 in a mk2 xr2 does fly! (at 110 mph all 4 wheels off the ground!)

[jayrs]

i know the later xr2i came with the anit roll bar, but im sure the 1.6 never had it, sorry should prob of made myself a little clearer.

i know the FRST has its very own rack made for just that model, if yours is a quick rack maybe you got the same one.

as for the shocks, no its not worth it, if you have uprated shocks its not gunna do a thing as all after maket shocks for the 2i and rs are the same, if its just lowering spring, the FRST shock will make a little difference as there a little stiffer but its not worth hassle for what little you would gain

[MAD_Adamski]

i a tad confused here as i got a rack for my rs and it was the same as all fiesta's when they looked it up in the book?? the RS model was the same part no as the other fiestas...

[Tomdom]

some 8vs did have a rear arb

and for anyone interested this might help

[jayrs]

is it a unipart rack? if so, get shot of it as uni part do 1 rack for the fiesta (unless its power steering) and its the wrong one for the FRST,
problem i had when i got a uni[part rack was the lock to lock to long and the wheels were catching the inner arch and on one side the track rod end!
i had it off and centralised it 3 times to try and make it better, which it did a little, still caught the inner arch, and i had to have this on my car for 2 years while waiting for one from fords!
the only other place i know of that do a separate one for the FRST is XL, but i had my ford one by then

trust me mate the rack is different, call ford's, there comfirm this.

[MAD_Adamski]

shocking guess i have the incorrect rack then!!!! have to pay ford's rediculous price for a new one

[jayrs]

i was told at the time if i had my old rack they could recon that for £30.

[beanyfrst]

xr2i's had a grille in the fron where as the RS Turbo didnt

[MAD_Adamski]

i was told at the time if i had my old rack they could recon that for £30.

ok heres 1 for u i had the 1 on my rs and i was runnin a xr the xr still at mates being broken now i think i put the rs rack on the xr?? but cant remember !!! but i have one on the rs too and the new one!!! soooooooo the question is how do i know which 1 to get reconed??? i take it u mean ford will recon it???

[jayrs]

yeah fords said they could but TBH if you know what your doing and someone will sell you the bits you can di it your self.

you check what rack is right, get the part numbers off them and check with ford.
that is if there gen ford parts.

[Project]

Errr........ <bites tongue>

[jayrs]

what dodgy info then? ( i saw the post before you changed it Project
fiftyoneCL
why and like what then?

[jayrs]

bitting ya touge now!? i happen to know what im on about thanks! if you think you know better than anyone else on this post and you think the infos cr@p, tell us why or butt out!
and my info is not dodgy, its the truth.

[nick.king]

The main difference is the XR2i is pap the RS TURBO isn't

Sorry I didn't reply dude - been working all day.

Couple of things I spotted that I know aren't right...

- FRST and 2i racks are limited to the same amounts (FRST gen rack is slightly "quicker").
- some 8v 2is had rear ARB (all had front ARB) - some even had complete FRST running gear (but not gearbox).
- FRST lower arms are ~2-3mm wider and castored backwards by about the same amount, giving 5mm wider track and a more neutral handling response for better high speed handling.
- FRST shocks are normally no different to XR2i 8v shocks.
- FRST springs are (new) 25mm shorter at kerb weight than 2i 8v springs.
- Zetec Mk3 fiestas all have the same running gear - 25mm lower springs, gas shocks, but the lower arms are closer to the 2i 8v geometry than the FRST's (the FRST had a little too much camber as standard). Not sure if the rack is as quick as the FRST.
- there are about 27 different Mk3 fiesta lower arms listed. A lot of these are probably the same part, but genuine FRST lower arms are unique. Lower arms and racks are the only parts I would never, ever buy from a motor factor's - they just can't keep proper track of which part goes on which car.
- Car-side looms are identical between the same spec 2i 8v and FRST. Electric pack and heated front screen can be fitted to either (as well as most other Mk3s). Engine bay looms are very similar as well - a very good guide in the Guides/FAQs forum is available listing the differences between the looms.
- Engine-wise, block is similar (same but for the oil return from the turbo and associated sump baffle). Head is identical, *including* the cam. The differences are...
> FRST and 2i 8v IAT (inlet air temp) sensor
> FRST inlet manifold is bolted down slightly tighter (same gaskets)
> Turbo oil return and baffle (where fitted)
> Exhaust manifolds
> Oil-coolant warmer (sits between block and oil filter) and oil feed pipe
> Radiator/intercooler and pipework
> Fan switch
> AMAL valve and wiring
> FRST crank is fillet rolled (stronger)
- 2i interior carpet has blue "XR2i" inserts
- shells are different... nah, just joking - identical shells.
- clutches are identical (same part)
- engine mounts are identical

Think that's everything I've spotted that's a bit iffy on this thread...
