Ported Head, 1400cvh Carburettor

Post by foreverford on Wed Mar 12, 2008 2:08 pm

Lads, I bought a Brand New Ported Head for My Fiesta, I knw I was advised By alot of people not to bother, But The Head seemed Like A Good Deal,

I want to run it by you Guys, See If You recon it would boost My 0 TO 60,

Before I take the head to be fitted, I need to cop a Camshaft, I dont realy want to go for a sports cam, Im after a Brand New, Standard cam, cant seem to find one around, Would I be looking at about a ton for one?

Anyway, The head would require a skim before fitting, And It hasent come assambled, It looks like a good job though

What You recon lads, Should I feel any difrence

that looks a mint deal that mate, i'd get a sports cam for it, you got the ported head you may aswell get a good cam, get yourself a decent carb like an XR2 one or even a set of 40's webbers and it'll be great

Cheers Dan,

Ive Got a twin chioke 1600 webber on there allready,

Also looking now at the cvh22 camshaft, Witch would you go for?



I dont want to loose drivability around town, So I must choose wisely, I think the most I could go is cvh33, Any More then that, And It would Idle like a Mixer full of nails bounce

I would go for a sports cam over standard if you want to change the cam anyway.

Kentcams lists:
powerband
1500 - 6000: cvh26
2000 - 6500: cvh22
2500 - 7000: cvh33

I don't know what sort of revs is sensible on the cvh but 7k might be out of bounds anyway. One of the first two are probably going to be better. A guy I know had a supersports for his ka and it didn't have a lot of bottom end

Cam definitely needs running in, I don't know about the head/valves specifically. Theres probably going to be instructions with the cam, usually Xrpm for Ymins.

6500rpm+ requires double valve springs (usually supplied in the 7k+ camshaft kits)

The 22 is a popular choice.


Question: The Gas flowed head... the ports are opened up... it mentions re-cut valve seats... how many angled cuts in the valve seats is there? 3, 5 (5 is far better than 3way cut... and 3 is superior to just "cut" valve seats.

Theres a guide for re-building the cvh head somewhere, Ask greg.. he should be able to link you... failing that, i'll track it down...

if you want to improve your 0-60 bin your interior and everything that you don't need and buy a pair of R888's for the front two wheels

Cheers Lads

Im Pretty sure the Ported Head and The Right cam would get me 0 to 60
close to 10seconds, against the standard time of 12seconds

Im gonna have to look into those cuts dave, To be honest, I dont realy know, A closer Inspection will clear it up, It looks Like 3 though, witch is better then just the single as you say, Cheers about the guide aswel mate, would come in handy

But from first glance, It Looks like a realy gd job, Esp the zorst ports, And there is some tidy work done on the valves, I think, for what I payed, I got a gd Deal, Wasent gonna bother with these kind of mods, But I couldnt pass this up,

Looks Like Ill get the cvh22,

Ill need new springs and that, but Ill look into it and see were i can zig and zag,

Not getting My hopes too high, but I recon I might be able to boost her into the mid 90's range bhp

The 22 seems the best compromise. Before you get the cam see what you get on the head. If the head has new followers then it might not be worth getting a kit. Have a look on the kentcams site and see what you would need from whats in the kit

Im quite happy to tip around with My Fez, I find It Great Fun, Love the car to bits

Cheers Dan

Is there an Ashley zorst made for the 1400 carb model?, Bering in mind, the zorst under path would be that of a 1.1 model, Are they the same?

I was after a reploacement zorst before when it was 1100, but all I could come up with was a pepco back box,

what reg is your fiesta? if its a mk3 then an xr2i ashley exhaust will fit perfect, if its a mk3.5 then the si used a 1.4 CVH so either way you shouldnt have any problems getting an exhaust, flowing all that more air with the new head and cam will be no good if you cant get it out, it'll sound mint too
