Weber Alpha Throttle bodies

[Barn]

Any good??

[Graham]

a throttle body is a throttle body really, so it isnt really a case of some being better than others, they all perform he same assuming you have roughly the right size

[RChambers]

Ask Mk1 Gaz on here Hard to get parts for them I believe?

If they're 48mm ones then you can't buy the air filter attachments and will have to use socks or run them open . Your ok with all the 40's + 45's though . I've got a mint set of 48mm ones for sale at £500 with a linkage , fuel rail , injector mounts etc so half price ..........

Could I use a inlet for 45 carbs to bolt these to my engine???
Which ecu do you recomend???

[alladdin]

just a suggestion here trig,
if your willing to spend 500 on bodies and 500 plus on an ecu presumably , then would it not be worth considering the kit that retro ford do at circa 1400 all in? im sure you could get it with a close map ?
just a thought.

[trig]

Is it any good???

[Graham]

retro fords kit should be pretty close, its jevney bits plus an emerald ecu, nothing wrong with either

Yes they bolt to a normal cheap DCOE manifold . Use an omex E.C.U. mapped by my mate chris at Torque of the devil in Uxbridge becasuse he's the daddy

[trig]

Which TB ecu tou using then Gaz is the omex got any problems heard good and bad things.

[alladdin]

sorry about the thread hijack.
trig, since i imagine your looking at circa 200bhp with the new setup , wont twin 45 be struggling ? how high can you go on 45's ?

45 throttle bodies are big enough for about 250bhp,

carbs would be a different story, 2.0 8v engine and 45 carbs will run out of steam 170-180bhp whilst they will go on to a little over 200bhp on a 2.0 16v.

[alladdin]

in that case trig might well be able to keep his carbs ??

[trig]

Dont want to keep the carbs was gona sell my set up as a running set up that you could come and try out before you buy thing I would get best money for it that way.
selling it complet meens it easy for the buyer to get do a quick engine swap and know that its gona work frist time.

sounds a sound plan

My 16v 2.0 Redtop did alright on twin 45 carbs at 240BHP

[mk1 gaz]

Which TB ecu tou using then Gaz is the omex got any problems heard good and bad things.

I'm using the weber alpha ecu that came pre-mapped for my engine , with my engine . Any tweaks to the set up have to be done by my local weber main dealer in south wimbledon . My mate Chris fits omex ecu's every week and never has any problems with them , if mine wasn't already done when i bought the engine then i would have just got one of those . I bought jenvey 48mm throttle bodies because i couldn't get a proper looking air filter for the weber ones as they don't make them for the 48's ( only 40 +45's ) as they are a special order . I special ordered them twice and waited months but then just gave up and bought the 48mm jenveys . I could have used filter socks cable tied on but don't like the look of them even though they would have been ok and saved me lots of time + grief !!!!!!!! ..............

[RChambers]

Filter socks will lose you power though so not the best solution. Pipercross do a nice twin carb type carbon or plastic airbox that could be made to fit

[mk1 gaz]

Here you go then , 48mm weber alpha bodies and all the bits except filters , injectors and t.p.s. only £500 so save a fortune

[trig]

Ok poeple did a bit of ringing round today ended up talking to a guy that works in a tuning place with a mk2 rally car running a duratec, and he sayed that the weber kit is alright dose what its ment to but is exspensive and not as tunable as the omex system. Im gona try to see him (and car) on saturday, so more news then.

Could go omex ecu and bike TB.

Gaz I know they cost alot but that dont look like mush kit for £500.

[mk1 gaz]

Well that stuff in the photo bought new is big money and new complete jenveys aint much cheaper once all the hidden extras are paid for . I know because i've just bought some.

[trig]

what else would I need to buy Gaz and ruffly how much you think it all would cost???

[mk1 gaz]

lots of stuff and lots of money mate . You can use scrap yard bits etc but unleaded fuel ruins everything if left inside injectors + pumps for long periods so be warned . You can also convert your existing fuel tank etc or buy a nice alloy injection tank + platform but again this is only upping the price . I'll price up the dear bits first but add lots of money for the little bits as well ( fuel lines , brackets , fittings , multiple sensors etc ) . New injectors are expensive but it depends on which sort/make you need but say £300 , ecu £500 , Mapping approx £250-£500 for starters , pre-filter £60 , fuel pump + high pressure filter £80 , Throttle bodies are about £1000 with air filters and all the little bits they need + postage etc . Everything you buy costs MORE money than you think , if it's advertised at £100 by the time you've got it delivered and in your hand it will be £130 !!!!!!!!!! . RChambers + myself have done the fuel system with the standard tank gravity feeding the pumps under the boot floor and this is much cheaper than the "bling" alloy injection tank + swirl pot method . Also we've used 8mm copper tubing under the car for the flow + return fuel lines to the engine which is again much cheaper than braided aeroquipe lines everywhere .

[trig]

Sounds like a lot of hassel to me, think ill stick with the carbs

but saying that would I be better of usibg the money to work on my engine maybe 2.1 and larger valves???

[mk1 gaz]

I would too mate . You only need injection if using a full race engine with peaky cams etc because all you gain is driveability and you ONLY gain driveability if the mappings right . A fast road spec motor already has driveability using carbs so no point changing unless you want to spend £2500 to save 50p in petrol when cruising at 3000 revs on the motorway !!!!!!! ..........

What sort of performance are you after as this will affect the spec from the start ? Now i know i'm going to get flack for this but just flogg the zetec mate because tunning it is too bloody expensive and they don't go that good . If you want a standardish engine then use a vauxhall XE instead or the best way is a snorting pinto with carbs + a dizzy ............

[trig]

Thought you mite say something like that mate

Only touble with a 200BHP pinto is it not realy any good for the drive to work.

What Im after is something thats got the power but ant stupid to drive every day was looking at the S2000 but still lots of money but the way this is going mite start looking agian.

[mk1 gaz]

Well a 180 bhp pinto would drive to work ok but a 200+ bhp one might need £2500 worth of injection system to smooth out the low rpm instead of the twin 50's coughing . Get a vauxhall mate mate BUT 200 bhp ones around here can't beat the 180 bhp pintos for some reason .........

[mk1 gaz]

I'll sell you a complete vauxhall XE red top engine from a 16v astra gte , the weber alpha 48mm throttle bodies with the manifold to fit the vauxhall for £800 . Whack some cams in it and it should make 200+ bhp and drive to work ok ........

[trig]

Got a xe lump laying around my dads somewere.

[Ratters]

Give Pig a PM Neil [NTS] was fitting a S2000 in Millsey's Harrier but I don't know how far he has got with it Trig

[RChambers]

200 bhp in a zetec is only a head skim, set of cams and possibly a light head port away anyway. Your 45's would be fine for that and as you already have mappable ignition you have most of the benefits of a fully mapped (injection) setup anyway. Can't see it costing more than a grand at the very most even if you pay top dollar for everything like Gaz . p.s. look to america for cheap zetec tuning bits

[trig]

Ive done all that apart from a head skim do you realy think Ill get 30-40bhp from that.

[Graham]

from what i understand most std 2.0 zetecs on 45's or throttle bodies will give 165bhp i dont see why you shouldnt see best part of 200bhp if you do a bit of porting, fit cams and give the compression a decent hike

[Barn]

Tb's will make the engine more driveable and give instant snap throttle response, on the road probably not much benefit, but in rallying where there are lots of 1st and 2nd gear corners, the carbs can bog down a bit, whereas TB's will give instant response etc...

The head was done by ron harris has fast road cams fitted.
Like I said if I skim the head for better compresion will it make that much diffrence.

what about putting st head on and keeping the carbs???

raised c/r would probably be worth 5-10bhp depending on what you have now and what you finish up with.

i dunno if an ST head will fit, as it comes from late type zetecs which think have a different bore and stroke

You could keep the carbs but not all carbs work well with the ZETEC. If your head has already been worked on it will probably be better the ST head by now. Save your cash and by a decent exhaust manifold which will help a lot.

48mm TBs would be over kill unless you have 250+ bhp and even then most people would stick to 45mm.

Ignore Gaz, he does not understand modern tuning.

[alladdin]

trig, what cc is your engine ?

[alladdin]

stella memory moment.
ok a std 1800 with twin t/b or twin 45 carbs and a decent ex manifold is reputed to give 150/155. it seems your harris head and cams are netting you about 15 bhp

somethings either wrong or the 18 doesnt respond to tuning ??
im guessing your cams will go in a 2.0 but not sure about a 1.8 head, i have a faint memory its not a good fit/idea.
might be better to sell 1.8 and fit/tune the st motor.
