Hi guys recently had a mad idea to go back to my roots and purchase a zetec s mk5. I'm looking at a turbo engine conversion and got advised on the zetec turbo engine by a friend. Im literally after a list of what I'd need ie engine gearbox loom ecu and so on.

If someone could list whats needed for :
ENGINE + WIRING

TURBO SETUP + INTAKE + INLET MANIFOLD + EXHAUST MANIFOLD +COOLING +INTERCOOLER

BRAKE SETUP

SUSPENSION

FUELING

ADDED EXTRAS TO PUSH CLOSE TO 300BHP OUT OF THE ZETEC TURBO ENGINE AND REMAPPING

All help appreciated guys thanks in advance 👍

No doubt you will come across the st170 block with standard zetec head, from my own experience don't bother.
Just buy a focus rs turbo engine complete with turbo manifold and turbo and add intake of choice and aftermarket ecu, you will also need to worry about the gearbox and clutch.
Once you have that lot bought and in the car then there's the alternator, exhaust and intercooler etc.

cost will be around £1200 for the engine £300 for turbo and manifold £500 for the ecu and lots for the rest so £3000 ish

Should you manage to get a working zetec turbo in the car then better brakes and tyres would not go a miss

I was gonna suggest mk1 frs engine, gearbox and possibly use the frs wiring loom and ecu.

Seen a couple of mk5's done this way.

It's not a straight swap hence why people drop a 1.7zetec in.
It can be done but it's not easy

Look here, these guys have done it

ST170/Blacktop route is a good proven way of doing it, mines great.

ok, please note this is my own view and prices are just a guide so make up your own minds

lets assume you have to buy the st engine £300 then a 2.0 zetec £150 then the head gasket £150 head bolts £30 and arp con rod bolts £70 you are looking at close to £700 on top of this there is a head skim and fitting of the oil return to the sump plus a few gaskets etc.

The big question then is do you have the tools, working space and skill to do it?

Once completed you get a good engine but for a little bit more money and a lot less hassle you could buy the RS engine which is forged and a lot better

Just for arguments sake say it cost £900 for a st engine conversion, there was an RS engine on ebay not that long a go for £1200 (had a broken exhaust stud but that's no problem)

Having just done this conversion last month and it did cost close to the price above, I feel its not worth it IF you can get an RS engine for a good price. Engine going in the car very soon so will update my thread

As said the st170 is proven to work well and it does of course all depend on deals you are able to find on the parts you need as to the final cost. But it's still 25+% cheaper.

I myself went the focus rs route. I bought the engine and box before the st170 conversion had become tried and tested. Engine and box cost me 1500 came with the head off as it had been away for some.serious porting etc. With ford headgasket new headbolts plugs leads coilpack etc. So it was a good price.

I must admit though the few I've seen for sale lately have been considerably more than what I paid for my engine and box for just the lump alone

I think either route would serve anyone well to be honest

studabear

Fair points raised, I ended up with about a grand in my engine but I used a brand new head.

If you can find a decent focus rs engine great, but to be honest I would only want to part with over £1000 for a engine if I could see it running and help remove it myself etc.

big_wasa

As above some very valid points and more besides.


Against the Rs.
Most of the £1k lumps have done over 100k miles. Cost of a water pump. And it's still not a forged engine.

For me, I have a garage full of zetec bits including a new head. New sump and lots of bits and bobs.

Buy a bad st and you loose £100~£300. Buy a bad rs lump and it would upset me some what more.

ST170 bottom end makes sense, tools can be bought, space can be rented and skills can be learnt, an RS makes good sense too but they aren't as easy to come by

Hi guys sorry been away all week so back to the grindstone today so it's either a focus rs engine or if I am right in saying a fiesta rs turbo engine which is the 1.8? are both the engines mentioned forged as standard ??

world of difference between a frs engine and that of a frst

Don't overlook bolting a turbo onto the SE engine, they respond very well to it!

xr2john

There was a bolt on turbo kit for these developed when they were 1st new by van Aiken I think they were called. Will see what I can find

Company was actually called Van Aaken Developments Ltd but they were dissolved in 2007 and there main man seems to work for these guys nowadays.

Hope this helps

Van aaken have a really bad rep sorry to say, lot of their stuff went up in flames.

Wasn't there a lad that had a company called OC Motorsport or something? He had had a green ZS turbo running over 300bhp iirc.

Churtz

It's definitely do able, but a lot of custom parts.

I have a zetec turbo in my mk4 (same engine bay) with just over 300bhp.

Makes for a real fun drive!!

And the Rs is Not a forged engine.

It does have better quality Mahle pistons but they are not forged. Rods have bigger gudgeon pin but aren't forged.

It has a very expensive water pump.

It has better exhaust valves.

Swings and roundabouts depending on what deals you can do.
