Ok straight to the point, im converting my xr3i convertible to RS engine spec this year, probably near the end of it as the shell is being restored first off. but im wondering what people have for recommendations of what kind of power they would recommend to put on the MFi setup that it has?

i have a standard bottom end in the garage with standard internals but no crank and sump with it at the current time (person i bought it from was selling seperate and didnt have money at time to buy crank which has now been sold on)

would i be able to use my xr3i engines crank and sump for this engine or are the parts different?

also......the head i have is a polished head with Piper BP285T cam, no vernier at the moment but one will be bought... what are peoples thoughts on this cam and are they troublesome? ive heard from a mate that piper cams arent too good in RST engines?

this will be the first turbo engine ive driven (apart from my old 306 dturbo sport) so im looking for a bit of advice on what kind of expectations etc i can expect from an engine with a light state of tune on it?

Is your xr3i running mfi currently or efi? Personally if I was building from scratch I would always go for an efi setup as mfi, IMO, can be troublesome! Circa 250bhp can be achieved on mfi, or even more depending on how deep your pockets are.

As for the cranks I'm pretty sure they are the same but be careful with sumps as s2 sumps have a hole in for the oil return from the turbo but s1 ones don't.

If you already have the piper cam in a decent head then I would be inclinded to use it. Some people don't seem to have problems but others do. I run a newman cam with solid lifters in my track car which seems to work well and doesn't cost the earth.

hi phil, the car is currently running NA on MFi management at the current time... apart from the power gains that EFi can have in regards to sorting out more power, is the system more reliable for running? the car wont be a daily driver really, the occasional trip to work (free valet) and some running about at weekends mainly but other than that occasional use as i have the C2 for running about in normally.

im after a decent amount of power that wont break the bank, but still be reliable. probably around 180-200 would be ideal for me, what kind of expectations do i need for that on a 1600 block? FMIC, hybrid turbo, -31 actuator, exhaust and filter and ecu? just going by what ive read on here so im not 100% on cvh engines as most of my engine work ive done in the past has been on TU series peugeot engines

efi is far more realible than mfi i.m.o dont get me wrong i dare say if you were to replace all components of the mfi sysytem then it would be reliable but i dont see the point as efi will give you more scope tuning wise etc etc.

is there much needed to the engine to change it over to efi management other than a fiesta efi head? does it have to be FRST or can an XR2i one be used?

If I were in your situation I would be looking into aftermarket managment such as Gotech MFI as this can be used without removing your current car loom, whereas you would have to replace the whole loom if you were to run a rst mfi setup. The system would be a whole load more reliable as you're not relying on 20 year old engine bay wiring and technology! They also seem to drive smoother on efi. You should see 180-200 very easily with what you have suggested. I would also suggest a bit of a port and polish to the head, a single pass FMIC and stage 2 T3 hybrid from the likes of turbo technics.

You can run your mfi head if you really want to, just buy a conversion plate so you can run a efi inlet from an xr2i/frst etc or I think NMS use a s1 inlet on their efi conversions which looks cool!

with the things i mentioned, is there much mechanically to worry about standard fitting terms at around that kind of power than could do with upgrading purely for safety and reliability purposes mate?

gotech would mean i could keep the mfi setup on the engine but have a bit more reliability engine management wise then?

would it take much for say an RS1600i rocker cover onto the engine?

i am in the process of fitting gotech.means gettin to remove all that crap mfi from the engine bay.i have got a jamsport side fed inlet so rocker cover wise i could fit the rs1600i but i have just powdercoated mines gloss black and it looks spot on.fitting a rs1600i rocker can be done with rs turbo cross over but it doesnt look quite right.

ive noticed a few people paint the bottom ends of the motors, is high temp paint to help keep it slightly cooler or just normal everyday hammerite? is there anything that can be done to the bottom end for 1600's that people recommend or its internals to incease reliability?

notice how i say "reliability" a lot even though its a cvh, i want to have one that actually will run good for a while without having nothing but problems and problems lol
