Robin Hood Zetec conversion

[FazerBob]

These pics are of my Robin Hood 2B shortly after carrying out the conversion to 1.8 Zetec. I am running 4 x bike carbs, on a home made manifold, and ignition by Megajolt.
I am running the Map option, with a threaded take off into each inlet tract, with four individual pipes into the balance plenum (which is in fact an old piece of exhaust pipe, polished to a good shine)

That's a very nice looking installation, I'm very jelous of the vacuum plenum, mine is currently cobbled together from plumbing supplies from Homebase!

One thing I did notice is the gause over the carb mouths, whilst this will keep out the larger debris it won't keep out the smaller stuff and it does really horrible things to the airflow capability according to Vizard. If you replace that with a good air filter I bet you will immediately notice a big difference.

that thing is BAD-ASS

where do you get the vacuum feed for the brake servo?

My jaw hit the floor when I saw that. Amazing! Where do you have the Megajolt installed?

If you ever want to sell, I'd be interested in importing it to the states.

Hi Guys,
Thanks for the kind comments on my Zetec conversion, I must admit I'm very pleased with the results. I will post a couple of new pics over the weekend, showing the new air filters, and the MJ location.

As promised a few new pics - proper air filters now fitted to carbs. MJLJ comfortably located on cabin side of bulkhead, and mounted on the same fixings as the coil pack

Looks just like the one my m8 had earlier this year however his was a 2.0 pinto on 40's but the colouring was the same rather nippy they are too.

just wondering if you had a map up and running you were happy enough to share as i'm about to fit a 1.8 zvh due to being the same bottom end i figure it would not be to far away.

[FazerBob]

no problem, here's my map attached.

If you want a map for a ZVH then your best bet is a CVH map and not a Zetec map. The thing that makes all the difference to ignition timing is in the head and the block makes no difference at all.

Personally I have difficulty understanding why anyone bothers with a ZVH as it's taking the worst bits from two engines and bolting them together. The CVH actually has a reasonably OK bottom end but the head is dire, meanwhile the Zetec has a very good head whilst the bottom end is good too but comparatively not as good as the zetec head.

The plus points of a ZVH are that you can keep your existing exhaust but that's about it as you still have to make up new engine mounts for the zetec bottom end and your induction system is going to need tweaking anyway to suit. Far better in my mind to plonk an entire zetec in there to get you the larger capacity, 16 valves, twin cams, an big wodge of extra power and better fuel economy to boot. Oh and a complete zetec engine that will give 150bhp just as it comes costs just £200 for a goodun or £650 for a brand new crate engine.

can't argue with that - makes a lot of sense. My 1.8 Zetec will be coming out in the next couple of weeks, to be replaced by a new 2.0. It's been fun having the zetec in the kit car, and it easily kept up with the 2.0 pinto's of my friends. all in all a relatively cheap upgrade without a lot of drama.

I get what your saying, but without hijacking this thread i'm already doing a 2.0 zetec for somone else and want to cover more than one engine with the megajolt as i was given 1.8 bottomend for nowt and had all the bits to hand seemed daft not to, zvh become more popular due to being a cheap replacment for a broken rst bottomend and gave a bit of extra power during the process but i will get a thread up and running soon for the other car once the weather turns.
