any advice would be grateful

[driftawayuk]

I have ordered my SEiW /Zetec 2.oL kit. It comes home end of Feb. i have bought a used Zetec 2.oL Zetec. If anybody could throw some light on which donor parts to source first I wouod be very grateful. I also plan on a Webcon /Alpha carb kit (£975) any thoughts on that too?

thanks and regards

Firstly Welcome, I hope you enjoy your build/ownership experience.

Secondly..Join the WSSC and become a member, essential for someone about to embark on a build.

You have the same setup as my build so the parts you need to think about include:

Gearbox (MT75 or Type 9)

Sierra rear calipers

Cortina Front Uprights and Hubs (or try Westfield's own)

Sierra B Type diff (LSD and ratio are up to you)

Steering rack

The sourcing of donor parts is entirely up to you, you can go to scrappies or you can go reconditioned.

Building a Westfield is a tried and tested process, conduct a search on this forum and you will dig up the answers to most things.

You have PM!!!

All the best

I would echo JamesD's comments. A lot depends on how keen you are on trudging around a scrap yard at a weekend getting the required parts. Some of the doner parts are getting rarer to find now, like Cortina front uprights and Allegro steering columns. The factory supply off the shelf items, but obviously at a cost.

The only other thing to bear in mind is that there are plenty of alternative suppliers for various bits and pieces on the car. Try some of the Speed Series sponsers, and companys in the links section on the WSCC homepage. For instance, I would personally recommend that you fit Avo shockers as opposed to the factory Spax units. They are cheaper, rebuildable, and IMO far better suited to the car.

Finally, keep your eyes peeled on the Parts for sale section.

The advantage of the Alpha is that it comes pre-mapped, so you dont have to spend time (and money) on the rollers.

It can be re-mapped (but only by an authorised Alpha dealer) if you up-grade.

You can get good discounts (try Southern Carburettors in Wimbledon)

Make sure you get the Throttle pot in the price, Southern included it in my XE kit Demon Tweaks charges extra for it.

Re Alpha ecu`s

Presumably `throttle pot` is the carburettor position sensor

I ask cos I`m still trying to figure out what I`ve bought and how it works

You say Alpha is pre mapped   I have a VX 2.0L 16v, so far I see its got an Alpha ecu, crank sensor, throttle pos sensor, an air temp sensor thingy (I think) and coilamp to dizzy thingy.

Is it not programmable/mappable like Omex. Why not (or why is Omex remappable   )

etc etc    

[Bananaman]

Have you thought of going Throttle bodies? rather than Carbs, i know it's a bit more expensive £400'ish but it will make your car much nicer to drive, may give more power & when/if you decide to sell your car will be worth more.

If i were building from new i would go down this route.

All the best

Hilux, Webcon AFIK sell specific kits for specific engines, I like you have the 2.0 XE kit.

The pre-mapped kits have what Webcon call a "safe" map and "safe" carb settings ie they err on the side of caution in terms of the settings because every engine is slightly different so they do not set the kits up for outright power.

If the ECU was factory set for maximum power the chances are a number of customers engines may be dammaged (Webcon can't control the type of exhaust you use for example, so if I had an SBD exhaust and you had a QED one our engines may need differing optimal settings) due to pre-ignition or running lean/rich for example

The XE kit hooks up to all the engines existing sensors and as far as I remember the only two supplied are the air temp sensor (mounted in one of the air filters) and the throttle angle sensor (throttle pot)

The system will run without the throttle pot but it will only be 2d the addition of the throttle pot makes the system "load sensative" as well IE 3d

I have no idea why the Alpha is not "home" adjustable but I'd guess Webcon do not want customers to trash their engines and then blame them for it when their "safe" settings have been messed about with.

I chose the Alpha over the the Omex/MBE ect because it was pre-mapped, I came to the conclusion that in the real world I do not need the adjustability of some of the other systems and the temptation to "play" and mess it all up is one that I'd rather not succum to.

The Alpha CAN be re-mapped but only by an Alpha dealer, so when you upgrade the system can cope with the mods.

Bananaman, realistically going to throttle bodies will cost about £800-1000 more than a good 3d system on carbs when you take into account swirl pots, pumps, regulators, new fuel lines ect ect ect.

Though the price between the Webcon Silver and Gold kits seems reasonable I calculated that fitted and running the Gold kit (EFI) would be at least £800 more to do it properly.

Please see here as I believe this to be the air temp sensor.

The original builder placed it on the side rail and not in the air filter.

Should it be in the filter? I have K&N cans and dont want to cut a hole

Does it have to be in the fast moving air in a carb or would positioning it just outside be sufficient:durr:

Pauls air temp sensor is in exactly the same place as mine.........I've never given it a second thought, 'cos it works, therefore it does not need fixing...........

I was told it should definitely *not* be in the air filter back plate.  The air temp there is different to the ambient air temperature and what you're trying to do is to correct the map for any major fluctuations in the normal ambient air temp, not at the point where the air is entering the engine.

My air temp sensor is mounted on the side of the pedal box out of harms way.

[chazpowerslide]

My kit came directly from Webcon via Southern Carburettors.

I pretty sure my air temp sensor is mounted in one of the filter back-plates.

Nick, who told you it should not be fitted there?

I can understand that the back-plate will pick up radiated/ambient heat from the engine, will this effect the opperation of the sensor?

If anything I'd expect the temp of the air being drawn through the filter to be cooler than ambient as it's giving away temperature as it's speeded up on it's way to the combustion chambers.

I was told this by Steve Broughton (SBD) for pretty much the reason you've just stated above.

The air temp sensor has an impact on the map (without being able to hook up my laptop and look at the map I can't say for sure how right now).  BUT, if the map has been created to compensate for these lower temps then it may very well be fine.  I just avoided it because the base map I was given assumed the sensor would be somewhere away from the engine and out of any cooling air flow.

[chazpowerslide]

Nick, kind of what i thought, thanks for that.

I think I need to call Webcon in the new year to clarify the base map has allowed for a filter mounted sensor and then re-locate it as nessasary.

I can't see how it will make a huge ammount of difference but it ought to "right"

Nick/Chaz

I agree with you both I think.....

IMO the air sensor should be placed as near to the intake as poss (not in the accelerated airflow cos this will have a "wind chill" factor)

I would be interested in your results/answers if you do do some research cos if the Alpha system is pre-mapped then it is imperative that the sensor is placed common to all cars with relationship to the air intake. ie: a closed engine compartment must have warmer air than an open or vented one.

Colder air is denser and will enable a greater amount of fuel to be emulsified therefore it must make a difference.

BTW just had me Xmas dinner and I`m sitting here belching and farting like an old boiler (ate too much)

              ooooh thats better...
