Just reading the zetec tuning page on here and it says for about £1000 I can get 200BHP with throttle bodies.

So with that idea what do I need to buy and for how much?

Which throttle bodies are the best?

I have a mate at ford so fitting isn't a problem.

Also would it be worth spending about £600 on cams?

What do people think of these induction kits?

K&N Generation 2 Induction Kits
K&N Typhoon Induction Kits
Pipercross Viper Induction Kits

Just wondering which to go for, I have always stuck with K&N int he past and know afew people who would recommend them everytime.

Also on presentation I think the Typhoon looks the best.

Thanks for your help as I know nothing about any or this.

FAQ by freak power answering my previous questions

1. How much are they and where can be bought? I saw some over BurtonPower but they are over 2k pounds, so I assume they are top of the range and I'd expect normal ones to be about 500?

1. Kits from £1800+ with this lot you get everything inc the management, loom, sensors and so on but you do get it fitted or mapped add another £500 to £600 more on top.

2. I know the fuel consumption of these are not as bad as twin-carbs, but how good/bad are they? And what about reliability?

2. Reliability is very good, no need to have them set up every 6 months like carbs, Fuel consumption is just as bad as carbs when thrashed.

3. Can I use any mappable chip (like Unichip) or do I need specifically designed management for Throttle Bodies?

3. No you need a ECU like a Gems, DTA, MBE, MoTeC, and so on.

4. What sort of power can I expect from an ordinary Throttle Bodies setup for 130ps 1800 or 130ps 2.0L?

4. 15bhp to 30bhp it depends

5. Except apparently the Throttle Bodies and chip, what else need to be changed? (providing the car already free-flowing)

5. Just the inlet, throttle bodies, ECU, Loom, and Sensors

6. Any bad points about Throttle Bodies?

6. Fuel consumption and the noise thay make, can give you a bit of a headace when going down the motorway.

7. Price seems to be expensive in terms of bang for bucks... I mean for about 2.5 to 3 grand you can get a low boost T25 pushing around 200bhp. So what advantage(s) do Throttle Bodies have over turbo-charging or super-charging? (or was it actually that the most expensive bit is the management?)

7." 2.5 to 3k for a turbo conversion" Who's doing this conversion for this price, Does this conversion have forged pistons or a decompression plate, 5th injector or the right management to run the conversion.

8. Why wouldn't an Unichip work? Why only expensive things work... Or were the managements you stated actually designed specifically for Throttle Bodies application?

8. The unichip is a piggy back ECU and i not capable of running this sort of conversion.

9. How bad is "bad" fuel consumption? Like 15mpg?

9. You could say that.

10. Do you have links for how Throttle Bodies work (in technical details), things I should know, things I shouldn't do, etc? Sorry I can't find anything constructive on Google.

10. Ring up Jenvey and he'll explain

11. So basically no engine internals need to be changed - can the whole installation be done DIY? Except mapping of course.

11. No, Yes

12. Where do you buy them?

12. Burton Power, Omex, Jenvey, Lumenition

13. Is there any super-charger kit available for Zetec-E AT ALL?

13. I sure someone could make one fit, Try Autocraft ?

14. By the way, may be a silly question, but do all those management systems include injectors?

14. If you buy throttle bodies in kit form then you'll get the injectors with it, you don't get injectors when you just buy a management system

-------------------------

Also on ZetecInside.com you will find a guide for throttle bodies.

Hope it helps.

Watch this space for a very powerfull N/A 2.1 Zetec 16v on twin 48's throttle bodies

[freak power]

Expect to send £1800 for a full kit like the Weber Alpha kit or Omex and thats to fit to a standard engine, if you have cams and a gas flowed head the ECU will need a remap.

Do throttle bodies on their own give extra power, or do they have to be combined with large injectors or carbs?

[wywywywy]

Do throttle bodies on their own give extra power, or do they have to be combined with large injectors or carbs?

Think of it this way, a throttle body = valve that allows air in when you press the accelerator pedal.
Throttle bodies kit = having one throttle body for EACH cylinder, instead of having one throttle body for ALL cylinders.

So essentially, it allows more air in. Without larger injectors and proper mapping, the fuel system would not be providing enough fuel - you want the air-fuel mix ratio to be 12.7:1 to achieve max power and min detonation.

The reason you do not need to re-map when you put a Mondeo 2.0L throttle body on a 1.8L Zetec is because it is within scope/capability of the original fuel management system... you know, they can self-learn to a certain extent.

For injection engines you don't need a carb

Is that clear?
Freak Power can you please correct my mistakes in the above statements as I am sure I've still got a lot to learn from you

Many thanks.

[freak power]

Thats right wywywywy

But i must say if can get a bit expencive, this is whats in my engine

Forged high comp pistons £600
Fardon steel con rods £700
Kent Cams £350
Kent spring kit £320
Focus-Central cam pullys £200
Bigger valves ( all 16 of them ) £320
32mm soild tappets ( Vauxhall XE ones ) £220
Shims for the above £40, machining of the head for the above £100
ARP stud and nut kit for head £150
Head work ie gas flowing and so on £400
Nology plug leads £160
Focus RS coil pack to run the above £55
Twin 48's throttle bodies £450
Fuel line, trumpets and other bits to fit them £200
803 Cossie greens £200

And thats just the start of it as i've got to get the engine mapped and that will be about £600

[Excursion]

Nutter!

[chumkila]

That is absolutely fly, what a driving experience it'll be.

[freak power]

Nutter!

It's not finished yet as i've going to fit a diffrent management like a MoToC, DTA or along them lines so i can run 8 injectors, 4 on the outer of the trumpets.
Some custom wild cams.
I'm having a better 4-1 manifold made up.
And maybe look into having it bored out even more from 2.1 to 2.2 with some 88mm pistons?

Yea, their "Option 1" kit is well cheap!
Check it out.

[Percy!]

Option 1 does look good

won't I have problems with emissions as thats with carbs?

Also would I need to buy the carbs how much would they cost?

[wywywywy]

Yes you would likely have emission problem...
That's price of full kit and carb is included (unless their webpage misled me)
