Hi there, not really ever posted in this forum but i think it's a good place to ask. I'm looking to do an RS turbo conversion on my car, the one in my signature, a 1994 Mk5b escort.

The engine in question is a rebuilt escort RS turbo, been standing for 9 months in a shed, well covered. It has Burton power Accralight Pistons with have been bored to +55 all done by burton power, with reciepts to prove. It has had a complete new bottom end, new big end bearings caps, bolts etc. and finally a reconditioned turbo technics t3 turbo.

I think this would be quite a good setup, only wanting about 150bhp from it as i'm only 19. Anyway, i've been playing with several ideas and it's come to a choice between this and a Blacktop 2.0 Zetec engine, which would be newer obviously, and a similar power to what i want, but i feel the RS turbo would just be generally more fun.

People i've been speaking to have generally said that the Zetec would be better for reliablility reasons, and that they've heard many horror stories about the RST engines blowing up etc. etc. and generally being unreliable. One has also said that it's old technology and would be less of an upgrade than the zetec.

What i'm wondering is how much of this is true? Are they notoriously unreliable? what can go wrong? I'm also thinking of using it to drive between essex and coventry a couple of times, and possibly a trip to the 'ring in september.

What are people's off boost fuel economy like as well, obviously i can't really moan with the extra power but it would be nice to know to see just how much money i might be spending weekly on fuel.

anyway, hope you can help, sorry for the long post and if i go through with it, hope i can stick around and be accepted!

Dude,
click my sig and see the last 5 Mk5 escorts i have built with over 240bhp at least

Full guides and info on the conversion with loads of questions and answers.

cool, thanks for that. I'm still concerned about the reliablilty issues though. What are people's experiences with this?

why not ask the owners of the cars

As long as its put together right you will be fine!

I thought that was what i'm doing here unless i'm very much mistaken

there reliable, if u biuld them properly and if ur not trying to get rediculose power. one of my cars (242bhp at the wheels) is a bloody nightmare, breaks al the time,
the other which is standard bar a zorst, filter and chip hasnt missed a beat in 20,000 miles.
on the near standard one i get about 250 miles to a full tank (45odd litres)
so not bad. an rs turbo will be much more fun than a zetec (personall opinion)

but it would be a easyer conversion if u used a fiesta rs turbo engine because it is already using efi (ur car should already have an efi loom ) where as the escort rs turbo engine is mfi (shite management)

as long as u look after the lump and have it set up properly, it will look after u


hope this helps mate

chappers

My car doesn't have an engine loom unfortunately as it's currently a TD, and this engine i've found seems strong, despite not having the fiesta management. I also can't for the life of me find a bleedin' fiesta turbo engine

in my opinion mate for 150bhp the zetec is the best option cus its n/a and has instant throttle response from low revs rather than lag etc but once ur 20/21 etc u'll be bored of that and want more power this will be expensive on a zetec but 200bhp+ is relatively cheap on a rs turbo lump
if u only want 150bhp for now ur engine will be very reliable aslong as its setup right cus 150bhp is easy power for a rs turbo engine so not many components are under alot of strain causing them to fail

chappers

I see, so if i wanted a simple 150bhp, then a Zetec would be a good idea, but would be difficult to improve later without spending £££. The RS turbo will sound cooler, be more fun and pretty solid if running it at about 150-170bhp

Will i get any chatter if i run it with a cone filter? Obviously minimal amounts because it's not fiesta management, but still some right?

Chris69

u'll be lucky to get chatter using mfi and only 150bhp ish tbh mate even with a cone filter- the mfi has a system in place that overides chatter unless ur running real big at least 200bhp power.
if u want chatter u need efi mate or something like cossie management

chappers

Balls. I don't really want a dump valve any more, having read a few threads here, but i've gotta have something to listen to when i open my windows! From what i read on the "www.rsbible.co.uk" it says to "simply change the engine"

Meaning i'd have to find a damn FRST engine and that brings me back to square one!!

Or am i just getting confused here?

How easy is the cossie management? Are there any aftermarket managements i could use that would make it easier?

my mfi chatters quite well, but im running 21 psi lol, the daily one is running 10psi and about 155bhp, and that chattered lightly (you could hear it with the windows up lol) but i chucked a dv on because its an xr3i with a turbo lump lol.

with the power your looking at, u dont need efi, and the sound of the turbo boosting will be plenty for now

chappers

I don't know really, call me sad but i can already hear my car boosting, it's a TD... the whole point of changing it and spending all that money is the extra power obviously and the noises it'll make... If i can't have those noises without a load of hassle then i might as well get the zetec

Helpful Technical info then???



Any system you choose will need to be triggered!! I.e it will need a CPS and depending on what system you choose, you will also need a phase sensor.

Weber (Cossie)
Is one of the easy, cost effective & best running systems out there for many many reasons!!

why you ask..

Mapping costs + anyone can map it in the UK.
Parts cost is so low. An ECU can be found from as little as £50 (The same ECU that runs 450+bhp in some cars)
Easy to get parts for like sensors and components etc..
etc
etc


You really do need to look in the right places for the info you need

chappers

yeah, your forum seems like it could be useful, but it's quite bloody big and i haven't got a clue where to look for help
