If I go ahead with a project with my cabby, should I go for a 2.0 Zetec transplant and put it on carbs, or should I go for an RS Turbo engine? The car is a '91 model so would it pass emitions tests with carbs on?

Markb_s1

up to you mate.. rs turbo lump is probably gonna be easier/cheaper.. depends if you prefer N/a or turbo.. what kind of power output are you looking for out of this?

neilm

The 2.0 Zetec on carbs will give you anything from 165bhp upwards...

They can be mapped to meet the emmissions

Will be fairly bullet proof and reliable.

Personally I'd go for the ST170 motor on bike throttle bodies or carbs as its a stronger starting point.


As for the RS Turbo lump... the world is your lobster... plenty of 200BHP+ cars out there, stuff readily available and cheap.


If you decide to go the Zetec Route let me know, I have a contact who does a lovely throttle body and engine management kit.

Neil, ST170 Lump might be a bit too expensive to lay out on plus the cost of TBs and possibly paying for the swap to be done.

I may have a DIY attempt at it over a weekend if I feel confident enough but at this point I dunno, not done it before.

As it stands now, I want a new gearbox and as a precaution I will change the clutch but I don't know which parts I'll need. If I go Zetec then I'll try and get a Mondeo mtx75 box. As for clutch, no idea about that.

Don't know what will be the most cost effective route. What would be the main difference in performance between a 190bhp turbo cvh and a 2.0ltr Zetec with 165bhp n/a?

Ginge !

how would you get round the VVT in the st170 engine then ????

BlueSmoke

If the ST170 engine was hanging on by a thread to be my choice, then it's just seen that thread snap

BlueSmoke

What would th fit be like on a V6 duratec out of a mondy?

Andy-R

If you do go the Carbs/Zetec route try and get a hold of a Series 3 Zetec-E engine.

The block is stronger than the Series 1 & Series 2 has a more metal between the bores added to that it comes with solid tappets meaning improved valve control at high RPM.

The only difference between this and the ST170 engine is the variable cam timing on the Exhaust valves....purely an omissions rather that performance related change.

BlueSmoke

Would that be the engine from the mk3 Mondy then?

Andy-R

1998 Focus/Mondeo onwards...black top in Plastic with 16V Zetec on the right handside as you look into the engine bay.

neilm

Easy... you can either have it on a switch.. which is nice... or alternatively you use the shift light feature on the ECU set it to when you want the VVT to kick in and away you go...


And bike throttle bodies

The beauty of using the ST170 motor is the plastic inlet manifold, motorbike throttle bodies sleave straight over.. Use the original Ford Injector

Far cheaper than buying a pair of 45's and an inlet manifold.



How do I know all this.....

Because my mate Dave Colledge at Retro Ford put one in an Anglia......

BlueSmoke

Ah the black top. Seen those about but didn't realise the difference.

I thought those engines different by 34bhp as well as the VCT tho?

Or is the mondy bhp figure quoted at the wheels rather than the flywheel?

BlueSmoke

Neil, how would I know which TBs to get and where from? Do you know anywhere decent for supplying an st170 motor if I went that route?

neilm

Give Dave Colledge a ring at Retro Ford on 01536 747978

E-Bay mate for the TB's or a bike breakers GSXR 1000's seem favourite, but check with Dave.

And ring round the local breakers, there are plenty of ST170's out there and a goodly few are getting smashed up...

BlueSmoke

ST170 engines fetch a much higher price than a regular black top mondy engine. I can't really spend a massive amount here to be honest so it might be out of the question.

neilm

Without being rude... you havent got this have you....


If you buy a 2.0 Zetec for say £200 from a breakers you are still going to have to pay out for an inlet manifold £100'ish, a pair of Weber 45's at £350 each and a linkage £75

(NOTE to all smart arses... the prices are rough figures this is not a quote)

Bike throttle bodies are like £80-£100 from a Bike Breaker.

So if you have to pay £800 for your ST170 engine you are still up on the deal.

If you get one with the 6 speed box attached you can sell that on to Focus owners and get some of your money back that way.

Obviously which ever way you go Carbs or TB's you will have to add an ECU and Loom to the cost.


I guess you could stick bike throttle bodies on a standard 2.0 Zetec and run it with a MegaSquirt DIY ECU and that would be about as cheap as it gets

Nip over to Turbosport (www.turbosport.co.uk) and check out the Old School section they have on Zetec, I believe a chap called 'RChambers' has done something very similar in a MkII Escort

BlueSmoke

Sorry Neil, I didn't realise the price difference between webers and bike carbs

Dan

The way those RST's performed last friday...

BlueSmoke

If I went the RST route, what would I pay for a circa 180bhp engine in decent nick with a gearbox and would I have to fuck about with my power steering?
