guys how do you go about making an xr3i inlet manifold run on an rsturbo engine????

i hate the look of the mfi inlet so want to do something different and im sure ive seen an rs turbo with one before but dont know whats involved

 

running it on mfi?

 

yep, theres nothing wrong with mfi`s budd

 

only ones I have seen have seen using the xr3i inlet have been running after market management.

 

ok thats fair enough but what is needed to make it work???

 

thats not why i asked if it was running mfi it was not a put down

the mfi erst throttle body has i different shape mounting face so you would need to change weld and tap a new hole as the erst tps works the opposite way to the efi one then the injector setup is completely different then its just the vacum and sensor side of things, seem's alot of work tbh

 

do u mean the MFI like xr3I stuff? early one?

 

cheers for the info budd i just wannado something different and plus i have an rs1600i rocker cover and dont want a crossover pipe covering it up lol

 

are you looking to fit an efi inlet or mfi xr3i or rsi style inlet???

 

Here you go mate!



RSi inlet & rocker cover running MFI.

Use the RST injector rail bit between the inlet and the head as theres the thermo sensor you will need. Also need a new fuel line to the cold start valve as thats in a different place and the XR one wont fit.

Throttle body just bolted on with no problems but you will need to change where the throttle cable clips onto from the XR throttle body to the RS one as they pull in the opposite direction.

Theres probably a few other bits but its straight forward when you look at it!

There are many differrent options.

1. Use a MFI inlet and make the RST throttle body fit the inlet
2. Use a RS1600i inlet, the RST throttle body fits fine without any mods
3. Use a MFI inlet and a KE-Jet N/A throttle body. Really rare for you boys, iirc this engine wasn't sold in the UK, it's a 1.6 CVH, 8,5:1, 90 hp cat engine with KE-Jetronic. But I've seen a Ford adaptor plate in a thread here a long time ago, made the RST throttle body fit the triangular shape of the MFI inlet manifold...





Belonged to a friend of mine. Used to ran on WM management, later on VW Digifant. But the setup with the RSi inlet and the turbo throttle is just how you want do do this!?

 

they do look 100 times better then a rs inlet

 

cheers for all your help guys both those cars in the pics look sooooooooo much nicer than the standard turbo one

 

i thought you were trippin' thinking it would look good

but that looks sublime

EDIT: i was going to punt my MFi XR gear but i think i'll keep it just incase now

 

RSandy thanks for the link budd that inlet setup is now mine.

kev i know it sounded silly but i had seen one before and thought it looked much better and just give the engine bay that different look.

just so you know i dont have an rsturbo escort either lol this will be in my xr2 turbo track car.

 

Anyone know if a cossie TB would be a straightforward fit onto an MFi XR3i Inlet?

 

so what you are saying guys is if i had a s2 mfi and wanted to change the inlet a xr3i is usable but needs work done to it as the rs1600i will bolt straight on yeah ?

 

XR3i had a 3 stud bolt pattern. But XR3i MK3 had an adaptor plate because they used the RSi/RST type throttle body. So you can make both fit. XR3i might be easier because of the brake fluid reservoir on RHD vehicles
