Scort_CVH Posted October 30, 2010 Share Posted October 30, 2010 Alright peeps I'm looking for some advice basically I'm going to be turbo converting my mk6 using a fezza rst engine, my question is what does this engine share with the erst s1&2 ie turbo pipes, coolant pipes, manifold, engine bottom end etc Ta muchly, few auctions ending soonish hence the urgent lol Link to comment Share on other sites More sharing options...
Stu Posted October 30, 2010 Share Posted October 30, 2010 Most of the parts between the mfi and efi engines are interchangeable - the efi block is slightly different in that it has the mount for the crank sensor (needed by efi/eec-iv management) in a similar way to a zetec.. the efi head is slightly different to.. For hoses and mounts and stuff, for a mk6 escort you'd just use the CVH stuff already available for it.. Link to comment Share on other sites More sharing options...
Scort_CVH Posted October 30, 2010 Author Share Posted October 30, 2010 Thanks stu, could the block me modified for the sensor or would I be better to just wait for a fiesta one? So I can use my rad and hoses (mine is a cvh). Link to comment Share on other sites More sharing options...
Stu Posted October 30, 2010 Share Posted October 30, 2010 Yes you can modify the block, but it's a bit of a pain? I'd also assume any used engine is in need of a rebuild too, so don't get your hopes up too much! Link to comment Share on other sites More sharing options...
Scort_CVH Posted October 30, 2010 Author Share Posted October 30, 2010 Right so fezza it is yeah I'm expecting a re-build, so I'm going to get everything else together while i save up for the build. Appreciate the help Link to comment Share on other sites More sharing options...
Stu Posted October 31, 2010 Share Posted October 31, 2010 If you're going to rebuild it then you might as well just turbocharge a zetec! Link to comment Share on other sites More sharing options...
Scort_CVH Posted October 31, 2010 Author Share Posted October 31, 2010 I know it sounds daft but as it's my first engine swap and it's not a standard one, I'm being a wimp and playing it safe as I know there's loads of standard parts out there, so if it all goes boom it hasn't cost a fortune lol.

Stu Posted October 31, 2010 Share Posted October 31, 2010 That's fair enough. In that case just drop the engine straight in and smoke it around for a bit to familiarise yourself with the conversions. Tuning the FRST ecu is an expensive process though as only a couple of people in the country actually do custom maps for it (and neither can really be bothered these days as its old junk). If you dont want over 200bhp, then i'd probably recommend going for an ERST setup.. as long as you get a decent metering unit (of which you can buy from anyone breaking an ERST) then you should be good to go.. just need a decent fuel pump. Getting an ERST to 200bhp is cheaper than a FRST setup - .48 housing on the turbo, CVH34 cam, good exhaust and suitable chip and you're good to go.

Scort_CVH Posted October 31, 2010 Author Share Posted October 31, 2010 Hmmm this is going to need abit more thinking. I was told fiesta as apparently the efi is more reliable but your post has got me wondering as the erst engines are so much more common. So the erst I'm looking at an easy and relatively cheap 200BHP. And the problem with the frst is the ecu and mapping - I've heard alot about sitech racing and they're close by, would they be able to sort the mapping issue? Think I'll decide by which engine falls into my hands first lol P.S I was told the standard cvh efi heads and frst heads are the same bar a coating on the valves and the cam, is this true?

Stu Posted October 31, 2010 Share Posted October 31, 2010 I don't believe Sitech racing can remap OFAB/OFAC - he typically recommends aftermarket management (gotech, or some other stuff)... which is obviously quite expensive in comparison... If you want to use him as your local tuner then it's probably best to have a chat with him before you embark on the project, however I doubt he (or any other tuner) will be too interested in playing around with some unknown used stuff/junk you've bought from ebay. It can sometimes be more hassle than it's worth. Is EFI more reliable than MFI? Considering both setups are quite old now i'd say it's probably comparable between them. The old mechanical fuel injection is really showing its age now but that doesnt mean you cant pick up a workable system (I mean most ERST's are still successfully running it). Old EEC-IV ecu's are a bit flakey these days, especially when you've got a J3/chip module stuck in the back. If your budget allows, i'd go for an EFI setup with aftermarket management (of your tuners recommendation). Sometimes it's worth travelling though, going to your local tuner may not always lead to the best results. Link to comment Share on other sites More sharing options...
Scort_CVH Posted November 2, 2010 Author Share Posted November 2, 2010 Picked up a EFI RST today, came with a t3(slight play but was holding boost - no smoke) and mani, and inlet manifold. Got a piper cam £250. Going to have a close look tomorrow, needs an exhaust manifold stud as one is snapped going to get the basics to get it started, get ic mounting points sorted and then upgrade from there. Known the guy for over a year now. Obviously it will be getting a timing belt kit and waterpump as well as oil and filter. If anyone has or has had a fezza rst i would appreciate any pics on the engine bay, going to get myself onto fiesta rsturbo aswell. Link to comment Share on other sites More sharing options...
bluliz Posted November 5, 2010 Share Posted November 5, 2010 Picked up a EFI RST today, came with a t3(slight play but was holding boost - no smoke) Seen with your own eyes? IIRC they should be a small amount of play but only in 1 direction..... Link to comment Share on other sites More sharing options...

Scort_CVH Posted November 5, 2010 Author Share Posted November 5, 2010 I'm not bothered if the turbos asway at that price but it's only up and Down . I'm needing to know what parts I can recyle from my 1.4CVH as it's needing a coilpack, and loads of wee hoses etc. Obviously I know I need fezza ht leads, and ic piping Link to comment Share on other sites More sharing options...
