2.0L Zetec setup...

[JamesD]

I have just become the proud owner of a 2.0L Zetec engine and am in the process of cleaning it up ready for installation.

However I need some help from the wise.......

I have decided to go the carbs route probabaly 45's. What is the best ignition system to use with this set-up. I have heard much talk about 2D and 3D ECU's but am unclear about the performance issues. Currenly I have no ECU at all...

Any suggestions about the best way to go with this setup would be much appreciated, also any ideas how these aftermarket systems integrate into the standard Zetec/SEiW loom?

Any help would be appreciated as I wish to be confident I am going all the right way before I splash my money about.

Regards,

JD

I'd go for throttle bodies from Scholar Engines. Not much more than carbs and infinitely better.

I spoke to Terry at Dunnell today aside from being able to give me accruate dimensions (crank C/L to oil filler cap and underside of carbs to oil filler cap) so I can work out how low I can mount a Zetec in my Pre-lit, he is also VERY clued up on all things Zetec. Visit their web site for the details I think you'll be impressed. The thing that I find attractive is the pre-programmed ECU as it will save dyno time and thus cost. Terry recons about £1500 to £2000 to do the whole lot on their 165 conversion (2 litre) This is probhably the route I'll go down if I do the conversion myself.

45`s are going to be better than 40`s for a 2000cc Zetec regards to management system a 3D system will give you no more power than a 2D system on full throttle. The 3D system is much better on part throttle than the 2D system as you will have more ignition advance on part throttle. This will make the car much nicer to drive. I am currently running a Dunnell ignition system on my modified 2000cc Zetec. The car will take full throttle from about 2000 rpm and can go as low as 1200rpm on part throttle even with the 40mm chokes that I am running. You should go for 36mm chokes on a standard engine. If you go for a 2D system on carbs you will be getting about 18mpg on my 3D system I get about 28mpg. All that said I am now going for throttle bodies but if you want to keep it simple then carbs and a 3D system are the way to go.

Mat I'd be very interested in your 45 DCOEs if your when you convert to throttle bodies.

JD,

I can also vouuch for Dunnell. Bought carbs, 3D system and exhaust from him. Bolted on and has ran perfectly without touching it. Pulls 5th at 1200rpm.

2D vs 3D; ulitmate power is the same, it's only on part throttle that the 3D is more responsive, it'll also give you 5-7mpg more. With any system it's only about another £100. (do enough miles and it'll save you money)

Give Dunnell a call, he's very free with his advice.

[Matt Seabrook]

Sorry Chazpowerslide I have sold the lot already. Carbs ignition management and manifold. I am just waiting for Jenvey to pull there finger out and supply me with the tapered t/bodies they said I would have by the 6th of March and then said it would be by 13th of March and then they said it would be by the 22nd of March. Guess what I am still waiting for them. They have now promised them for next week. If I could only get a straight answer I would not mind waiting but it’s the not knowing a reliable date that is really P*”!:?*G me off. Dose anybody know if this is normal for Jenvey or not.

Matt,

when you get throttle bodies up and running can you post a message comparing them to the carb set up.

I'm kicking the idea around but am undecided as to the actual advantages when on the road. (I don't need the car to pull from 1000rpm in 5th!!!!

thanks in advance

Carl

[Matt Seabrook]

No problem Carl i will be doing a review on my web site as well will let you know when i have more info.  

[chazpowerslide]

Mat what was/is the cost of converting to Jenyeys ? I love the sound and looks of the webbers, it would take a lot of convincing to make me want to move to EFI, I was wondering if the cost (£ per BHP) is really worth it if a DCOE can be made to work as well as the Dunnell setup appears to ?

[chazpowerslide]

That should have been "if a DCOE setup can be made to .......) sorry It's my birthday tomorrow but I'm working the night shift, so I've had the Stella(s) tonight !!!!!!!

[JamesD]

Spoke to Paul at Dunnell, very knowledgeable chap!

He steered me towards a a pre-set carbs and 3D ECU set-up due to cost, but what I liked was that the set-up was easily upgradeable as and when the money becomes available..

Thanks for steering me in their direction.

The cost to change from carbs to injection will depend on managment and type of injection set up. I am thinking on about 1500-2000 pounds but from the sale of old stuff should end up costing me about £1000. If you get carbs and management from Dunnell on a standard engine it will not need any setting up. I found that when I modified my engine though, that even though Dunnell supplied me with jets and chocks needed it still needed setting up on the rollers made a whole heap of a difference. The injection route may release a little more BHP, as the barrels of the throttle bodies will be a bit bigger. The throttle response will be a bit better on injection but the Dunnell carb set up is very very good. As Blatman will endorsee (well may be if he is not going on about Vauxhall engines)    

[Blatman]

Me? Waffle on about Vauxhall engines? Well maybe a bit.......

I can confirm that Matt's Zetec is probably the finest carbed (and by carbed, I mean twin dcoe's) car I've ever driven. I have no doubt Dunnell's advice is good, but Matt is fairly handy with a set of spanners too. Which helps........

Evenin' Matt. Digested dinner yet?

[Matt Seabrook]

Yep dinner went down a treat. Had a good fry up in the morning as well. Looking forward to the stop over at your place soon. and thanks for the nice words you sure this is not Blatgirl signed in as you.
