Cylinder head... Check!

Hi all, just thought I would share with you what I just got in preparation for the winter project now my car is off the road.

It's a stage 3 cylinder head for the standard pinto in my car. The aim this winter is to put the cylinder head on, change the stock carb for twin dellortos or weber 45s and add a lightened flywheel ready for next summer.

first part of the list has been acquired. Pics below!







It is a stage 3 cylinder head which is fitted with the wills rings for (apparently) better sealing to the block. It included a BF134 High Torque Camshaft which suits me as I prefer low end grunt and acceleration so should be ideal for next year if I manage to enter some sprints. Includes correct Pin type adjustable vernier pulley which are apparently much stronger than the newer alloy type. The cylinder head has just been rebuilt so is ready to bolt on!

The valve sizes are;
Inlet - 44.4mm
Exhaust - 38.1mm

Got it for a good price and can't wait to fit it and see the performance increase next year!

Matt

Edit: sorry for large pictures, don't know how to make them smaller. Always happens

have you considered a set of bike carb's instead of the expensive webbers/dellortos ?

what ignition system are you using / going to use ?
(there are much better options than the dizzy )

when it comes to lightened cast iron flywheels just remember that if too much is removed from the wrong places it go horribly wrong
(they can explode like a grenade doing loads of damage to the car and maybe your legs )
I went for steel flywheel, which is very light and strong - not cheap, but a lot cheaper than new legs !





do you know who did the work on the head ?

did they give you any idea of the volume of the combustion chambers ?
(or something to that effect like what compression ratio you should see on a stock bottom end etc..)

how much porting work has been done ?
has it got 3 angle valve seats ?
and so on.....

Obviously the missus was out when you took the pics, Ive got a pair of very good 40 DCOE's on a Pinto manifold with 2 service kits up for grabs.
Cheers,
Bob

i got a lightened flywheel and clutch available





I'd love to give my imaginary friend a great big hug,

but this jacket makes it impossible.

I have considered bike carbs however everybody keeps saying to me not to get them and they have used them in the past and they haven't been good. So will probably go down the electronic dizzy route.

I was looking at a steel flywheel for exactly the leg chopping grenade reason

An engineering company did the work on the head and has had a little porting done to it. Not a lot but some which should make a little difference. The guy who I got it from has been working on pintos for about 30 years apparently but looking at his ford rs2000 he had in his garage it looked immaculate along with pictures of him racing all over his walls he looked pretty confident in what he was doing.

Yes it does have 3 angle valve seats.

megajolt (or one of the other ignition only ECU's) will give you the ability to tune your timing to best suit 'your' engine which could make a noticable difference to the drivability (and maybe a tiny bit extra power)


also most dizzys have the vac. advance removed for use with twin carb's (or bike carbs) - thats fine, but its effectively a 2D map and that can badly hurt your fuel economy



just food for thought

I'm guessing the ignition only megajolt is around the £250 mark. The only problem with that is that I want to do this on a budget really so will have to take the money out of something else for the megajolt unit which will have to be the carbs. So I don't know if its cost effective for me.

What do you think?

well you can always do it later as fund allow.... (your old dizzy will run it, it just won't be ideal)

a brand new MJ v4 costs $151.90 + $42.00 p&p from the states (thats ~£120.59 today at a good rate)
if you want to avoid the international shipping carry-on then trigger-wheels.com sell the same thing for £129.99
you want the TPS version to use with the twin carb setup (also the cheaper option)

you can use any 36-1 trigger wheel you like (you should be able to get one for no more than £20)

the donor bits you need should be ~£20 - £40 if you go and get them yourself from a scrapyard
only issue is some of the donor cars are getting a little harder to find these days - but its still worth a look as it can save you a lot of ££
you can get the VR sensor from just about any 90's ford, the coil packs are also easy to get, but the EDIS4 is only on some of them (the older 90's fiesta's & escorts with 1.3 and 1.6's are the first choice - but also any of the 90's automatic mondeo's)
just remember to take the plugs with a decent amount of wire attached (I got the whole loom from a 1.6 fiesta with all the bits for £25 )

if your using twin webbers then a TPS from a mondeo or similar can be made to fit - they are about £5 for a scrapyard (most later bike carbs come with them attached )



so thats about £180 - £200 if you pay the right price for all the bits
any modified dizzy will cost you the same - so why spend good money on outdated tech at the same price
(unless you find a second hand bargain, but then the same goes for the megajolt too...)

Does that have hardened exhaust valve seats?
