bike carbs on zetec

[Captain Scarlet]

hi fellow spanner monkeys. After my last project didnt quite go to plan ( when i got a so-called expert to fit some bike throttle bodies onto my civic type-r. ended up taking all to bits and retting it properly and mapping it myself. ) next project is well under way now and the track fezza after a few teething troubles has done its 1st track thrash and all went well apart from a loose alternator wire.

Anyway down to the nitty gritty the bog standard 2 litre zetec ive nailed in is a lacking a bit of power. Have sourced a 4 into 1 exhaust manifold to replace the cast lump thaat ford provided. Replaced the CAT with a straight through pipe. Have just got some ZX6R carbs from the worlds favorite auction site. only thing is i dont have much of a clu on how to fit them. seems to have a lot of tubes and pipes that i dont know what they are for. Obviously some will vacuum be to go to the MAP sensor. Anyone fitted them onto a car?? do they need much modifying or do i just need to block a few things off and bolt them on??? Also is it worth having a play with the cam timing on standard cams or is that only better for something more performace orienated

thanks

Sell your head and fit a CVH one. The ZVH conversion is much more carb' friendly, with a distributor instead of all the gubbins easier to get running and a lot easier to set up. Also Burtons do off the shelf bike carb' manifolds for Zetecs and CVH heads so it's a fairly straight forward and painless experience.

[Captain Scarlet]

surely the zetec head is a lot better than the older CVH

[Relentless Rob]

The ZVH is more torquey (mid range grunt) than the Zetec which is better for day to day road use and has less variabbles making it easier to set up (dizzy and mixture). Zetecs are very rev' happy and are better for top end power that would be better suited to track days and competition use.

A decent CVH head, ported, gas flowed and with at least a 286 cam' would cost as much as an ecu and aformentioned gubbins these days. So the ZVH probably isn't the way forward.

As for the original question (sorry too many beers last night) the two big pipes go to the bikes sump breather, the smaller air pipes with a diaframs are vacum pipes usually to operate flaps in the air box and you'll have fuel in and out.

The guys you need to have a word with are the Bogg Brothers.

They supplied the manifolds for the cars I helped with.

there's millions of them out there in ordinary cars being driven by folk who dont like to rev their engines as they're only gan to work, the shops etc.

Haw! Aahhmm a hillbilly n ahh divint pootle on wi me Zetec. An 1800 in a Mondeo you have to flog it to get it to move.

For those from south of Middlesbrough a Hillbilly is someone from Consett, County Durham. It been known for council estates to have horses dwelling in them, sometimes in the Kitchen. Hence the name.

Eh? I hit the quote button and it looks like its edited the post instead. I'm sure I hit the quote not edit. Knackers. Sorry

Have been looking into camshafts and autosprint in birmingham do a 'carbs specific ' grind for the zetec. really want it as hassle free as possible hence cutting out as much electronics as i can get away with. Also im assuming that the bike carbs are of the 'down-draft' variety. ie they need to be angled up. is their an optimal angle with which to mount them.?? can the angle be calculated or is that for total nerds who prefer calculators to spanners and for us normal folk its try a couple and see which is best??

[hillbillyracer]

Ha ha, dunno what's happened when you've quoted me Oily, but I did set the puter to "sleep" still logged on if that had owt to do with it?
I do indeed live in the hills, but over on the wet side of the Pennines


Anyway Captain, have a look around on Locostbuilders: http://www.locostbuilders.co.uk/
Plenty folk with Zetec engines in Seven replicas & a few must be running carbs so you can have a bit look about for info there. You dont need to be a logged in member, you get pretty much full access apart from not seeing any for sale/wanted ads till they're a couple of days old.

will have a fact finding mission over the weekend thanks.


just out of curisoity. south of the border but north of the wall on the wet side of the pennines. anywere near longtown by any chance????

[hillbillyracer]

Langtoon?! Or Dodge City as it's sometimes called? About 18 miles away I think, closer to Brampton as it happens but right out in the hills. You from up this way too then?

[Captain Scarlet]

hmm. so your either out Gilsland way or in the far end of beyond up near Bewcastle. Am not to far away really, from Carlisle originally and still work down here at the university but migrated to the wrong side of the border. Am now in hiding about half way between Annan and Lockerbie

[hillbillyracer]

Right on the money there with Bewcastle, you obviously ken your way around the bit eh!
Ha ha, "in hiding", I know what you mean! I've no problem with folk either side of the border but there's plenty on both sides who have a fair bit of prejudice, a bit friendly rivalry is good but sometimes it's taken a bit too seriously.

.... nowt the matter wi' Longtown. I'm a Sanddancer [born] & hang in Wallsend... but AUTOBITS is my first call for that 'very reasonably priced...err, bit!'

ergo:- Endcover for my JB1 Gbox £10.... townies would have made me buy a whole Gbox.

I'm whitevanman... and go to Glasgow a lot... AUTOBITS is just local

[hillbillyracer]

Yeah it's nowt like as bad as some folk make out Longtown. Autobits, only a small place but a proper scrapyard experience, cars stcked up, loads of clarts & you can take bits off yourself!
Do you go to Pattersons at Brampton too? It'll be on you route too, a bit bigger, much less organised though!

[OilyFingers]

Is that place at Newburn still there? Norman Marshall seems to ring a bell? I used to go there as they have at least one of every car in history around and about and they give you a reciept. They were good for bike bits as well and cheap as I remember, I got two rare foglights for a 406 coupe for a tenner (ebay wanted £35). Ford Parts in Dunston near the 5 a side place is good and cheap too I got a complete front end for a Mk4 escort for 60 quid.

Mashall 'no roof' is still going strong.... Pringles are also cool. I got a FWBrg there, for my 2.0LPT SAAB for £30... complete hub/and a good disc on it.
