Zetec Head

[Colgate]

I have a Mk1 escort with a 2 ltr zetec fitted running fuel injection (Omex 3D engine management). The engine is a mk1 Mondeo silver top. I'm interested in fitting the Jackson Racing supercharger (should add some extra fun to the car.) however they have based it around the Focus as they don't have the Mondeo in America. Can anyone tell me if the inlet layout on a black top Zetec is the same as a siler top or not and therefore if the superchager would fit straight on or would need a new inlet manifold to be created.

hi, i am gonna fit the JR supercharger on my mk1 mondeo 2.0 silvertop pretty soon, it should fit straight on. theres a ford contour which has put this conversion on and its working well. whatever you do dont buy the kit from that numpty on ebay who is importing them to the UK for massive money. Import Car Parts Plus is the cheapest place to get them from in USA. they quoted me 2450 dollars shipped.

you will need to get a focus IAC valve, dont use UDP (it would cancel out the boost on the S/C), you've need to fab a bracket for under the jackson inlet manifold, block off the EGR, use something like a CTA or Bomz intake pipe

see this thread for info:

and theres pics here

as you probably already know, if you fit the smaller S/C pulley you will increase the boost from 4psi to 8psi. but, to make it work on 8psi you need bigger injectors (www.zxtuner.com sell a set of 42lb injectors for £140 plus shipping from USA) and a bigger MAF (properly calibrated to run them). ideally you want water mist for the 8psi aswell, the JR water aquamist thing is supposed to be crap, in US they prefer the Snow kit (its cheaper aswell). oh and ideally put on a oil cooler aswell if you want higher boost.

a chip or ecu upgrade isnt necessary, it was designed to not need it. however unichip can run it and tune it to work better.

the 65mm throttle body from focus central (again a US shop) will work much better with the S/C than the standard one.

make sure if you want performance cams that they are just mild, too severe will make the blower not work properly.

the M45 blower they use in the kit is the same as in a mini cooper S, which you can get one off ebay for £50 - £100. unfortunately it would need alot of fabbing to the outer casing to fit the J.R. zetec inlet manifold, and J.R. want something silly like 2200 dollars for the entire conversion kit minus the supercharger (they charge massive money for the parts separately so make sure you dont get a half missing 2nd hand kit off ebay)

You may not gain anything as the standard jackson supercharger gives less power than aftermarket management + throttle bodies. Are you still using the standard ZETEC EFI maniofld etc?

[PercyBigun]

TB's only give it about 30bhp dont they?

the supercharger in standard form should give at least 40-50bhp, and much more once boost is doubled and water injection added. plus i would rather have the supercharger whine and keep the fuel injection for the mpg and less messing about!

and TB's with decent management would cost more than the S/C (unless you use motorbike TB's but nobody seems to know how to fab a inlet manifold to put them on)

[Zetec_Escorts]

The manfiolf for motorbike TBs is simple. A flange in the shape of the original inlet manfiolf with 4 tubes welded on to it, it does not get any simplar!!! You attach the TBs via silicon tubing and jubilee clips.

Have a look at:

This is the jackson supercharger Rolling Road chart:

The webber alpha gives more than that at ony £200 more, + you can get better and cheaper kits than that.

[PercyBigun]

oh well the TB's looks alot simpler than i thought! make me one! i am tempted by TB's if i can get the whole system for alot cheaper than JRSC, but if its round about the same price i would much rather have F.I. any day.

remember that jackson dyno chart is showing wheel HP and has no other mods to the engine. some of the US focuses are on 210bhp and beyond with the JRSC and other mods.

The kit I originally did the conversion with was from Phoenix Escorts (worst mistake of my life !!!!!) I have since had many Retro Ford parts now to rectify this. The end result however on the fueling is as follows, Custom Plenum Chamber, original ford injection rail, omex 3D engine mangement system. When tuned came off the rollers with 161bhp 157lbft at the wheels oh and around 35 to the gallon on consumption 0-60 approx 6 1/4 secs.

Check out the web address for plans occuring later this year. My car is the blue one.

dunno about the economy but my current engine on 45s (otherwise standard 2.0 zetec) was rr'd at 170 odd bhp

and as for the supercharger... can't beat the sound.. just listen to the maclaren merc SLR!!!! best sounding car i've ever heard bar none IMO!!!!

[RChambers]

I've found the ideal solution to fitting motorbike throttle bodies to the zetec. If you get a focus ST170 inlet manifold it has four rubber pipes that just happen to fit straight onto my gsx-r750 throttle bodies. Good old Ford



focus Zetec 2.0 VVT (160PS)-Inlet Manifold (item9424B)
Part Number: 1233618

now that is very interesting...

jut one thing, the ST170 inlet has some kind of secondaries doesnt it, variable inlet tract?

[RChambers]

That is further on. This is the manifold that all that bolts onto. You don't need the rest though so it saves money

Richard

[PercyBigun]

so i could get one of them instead of fabbing one like in that previous post? thats loads easier!

[RChambers]

Yep its just the same as what people are making but the kind people at Ford have done all the hard work for us . I'll be getting mine next week so I'll take photos and measure it to see what it will work with. Not to bad for the price as it looks a lot more professional than a home made jobie.

Richard

[PercyBigun]

well i am very interested indeed!

photos of the install etc and any notes would be good.

the main bit i cant find any info on is the electrical side of it, the management, 3d mapping, all that is a mystery to me. i know Omex will run it but its very expensive. whats the cheap and easy way of doing it. would a reprogrammed unichip do it?

[FF_Mark]

Very interesting thread guys

I guess it would be easy to put TB on a ST170 then

[PercyBigun]

well yes but you would lose the variable inlet tract on the ST170 which is one of the good parts of it.

the JRSC for the S170 is much more powerful than the one for the zetec (M62 rather than M45) so it would p1ss all over having throttle bodies on it. theres a guy on STOC just JRSC his ST170 and he's saying its now better than a focus RS - he gets it dynoed soon so i wil let you know how he gets on.

and remember theres a much more powerful S/C available for the ST170 - the vortech. its intercooled so runs higher boost etc. it will kick arse with a vortech but its much more dosh than a JR. vortech adds 68.5% more BHP to a ST170 so iwll be around 285BHP (flywheel)

i looked into vortech for mine but it wont fit

[Colgate]

As for the electrical stuff to put TB's onto Zetec, I'd say talk with Dave at Retro Ford, he's done it and can supply the kit etc for you or probably give guidance on alternative options. Dave's number is 07813 436514

[Zetec_Escorts]

Just use a megasquirt and EDIS ECU, £170!!! You can't go wrong.

[RChambers]

I think we are thinking of us oldschool cars too much! For the mondeo I would definately go with the supercharger. Firstly its a fat lardy car and needs all the torque it can get . Secondly to run throttle bodies you need aftermarket management which means dumping the standard ecu. This has a lot of problems for a mondeo as this ecu controls other parts of the car as well. Plus you will need to make a new engine bay wiring loom to fit it. The last point is that can you get the car through the emissions test with a custom ecu? It would be hard (but not impossible) to have a closed loop system with a CAT so that the car is legal. Luckily we don't have to worry about that with our old cars!

Go with the supercharger so you can just bolt on and go

Richard

[PercyBigun]

yeah i prefer having a supercharger anyway - as you say less hassle its just bolt on and go.

and i can get much more power out of it than the 30-35bhp max i could get with TB's - once i've cranked it up to 8-10PSI.
