E30 Zone

lo all has anyone had the bbtb from the zone fitted to their car and if so can you give me your recomendation or not???? ............thanks.................j

yep ive had them on my iS and my 2.7 and its a really good mod

go for it

i think i may have upset ian questioning his engenering ability i didnt mean to just worded the email incorretly so i dont think he is responding to my emails i have sent an opology just hope he sees that it was a minor mistake on my part and gives me the info on the tb i need and if its right sells me one
................j

Have had my BBTB for about 6 months and it does make a big difference to the overall running of the engine.

Engine revs cleaner and seems to have a few extra ponies in the right places.

For the money you would be silly not too, great mod and Ian is a top bloke too, very helpfull and has forgotten more about e30's than most will ever know.

When you compare the std and the BBTB you'll see exactley what has been done and it makes just makes sense too do it.

ive got one and i'd say very good mod for the money.

scuse me for being thick, but whats bbtb?

and more importantly do i want one?!

It's the standard throttle body bored out to give an extra 16% or so extra air in, new seals and a larger butterfly flap.

More air in, more power out, but as it's only slight increase it doesn't effect the running or need anything changed to cope with the extra.

Gives the engine a whole new life, very worth while mod indeed.

thanks fozzy! how stupid am i? Big Bore Throttle Body

how much is the zone one, and will it work ok with the zone chip?

i think it works out as Ԛ£120 and your old tb and it wil work fine with the chip................j

Here's before and after for info- new one on the left. My car seem to rev much freer with the BBTB and is more relaxed at cruising.

can you get em for the m40 engines or only m20?

email: throttlebodies@e30zone.co.uk for all info.

There are a few options these days.

As for the chips, email ant@e30zone.co.uk I think Ԛ£55 or Ԛ£60, but when you stick it in, you'll be all day long!

Got one on my 318iS and it's superb. Well engineered and made a great difference.


Standard on left, BBTB on right (used so a little dirty)


On car...

they also come with tps switch,and set correctly.
Well enginered were my thoughts also.The 318 is one looks good,didn't realise they had a second throttle disk,a bit like a good old twin choke webber !!

It's to make up for the lack of cylinders

they look good......................j

whats the price of 1 of these ???

Ԛ£120 exchange

If they are that price i would have one if there any at the moment

Hi 325Dude! Convinced?

No probs with your emails. Drop me a line, and I will sort you one out. alpina527@aol.com

Yes, I do M20, M30, M42, and M40 bodies. All @ Ԛ£120 exchange.

hmmmmm yup that gets my vote i think there are more people wanting them now as well......................j

I have seen the work on ians tb's and i'v been trying to get one
already have a bbtb from else where but it's about 5-6 years old
and dosent seem to have gained size in on the butterfly.
but i did notice a difference, It made throttle more feel more
snappy, Ian if you read this iv sent e mails but no response and i
want one please..

You can get me on 07968391056

Will it make my M20 engine seem a little bit less revvy at cruising speeds? sometimes i feel like i am only in 3rd when doing speeds of aaound 80-90 think i will be in the market for one are they DIY or does someone need to tune it or something?? sorry for sounding dumb!

You say you can do the M40 engine. Will i notice much difference? And has anyone had it done on thier 1.8?

Cheers Adam

Guys, for the record, the e30zone sponsored 325 racer runs a zone chip and BBTB exactly the same as supplied to you guys from here.

The track is often the place to acid test mods because of the variation in demand on the engine and the combination of the bbtb and chip has proven to be superb. The engine pulls more smoothly throughout the range and pulls noticably harder in third and 4th on the racer. It's a well known fact that the M20 is restricted by lack of air getting in, and you WILL see and feel a diffference on even a basic engine.

Looks like the new site hasn't got the stats on the conversion posted, so I will ask Steve if he can dig them out and post here.

Ben - If the engine sounds revvy it's not really something a bbtb will make any difference to. My guess is that if you have a performance exhaust or similar then it will sound worse than it is anyway. The real benefit of the bbtb is in how well the engine will pull when you put your foot down and also when running at higher revs the engine isn't going to be choked for air quite as much. It's a bit like the Tunes advert!! "Helps you breath more easily"

Cheers mate! just wandered thats all! think i might be in the market for one coon! can you fit them yourself??

They are a doddle to fit. It takes about 30 mins

cool cheers mate!

Anybody have some charts from the dyno?

Horsepower and torque comparisons from before and after?

Gonna keep this on my mind for the future.

another Q about the BBTB, can i put it into an automatic, and will it increase the fuel consumption a lot?

If you look in FAQs you'll see a before and after dyno graph. That was my car and although it's a 2.7 it is also an automatic. You just need to swap over the automatic TPS to the new body. Easy job. Didn't change my fuel consumption. Just filled up yesterday and showed 29.7mpg after a trip to the west country and back plus a little town driving on top.

this thread has got me thinking, might have to buy a chip + tb before the wheels. not going to be using the car every day from monday as my company car turns up so f**k the fuel consumption...... wanna go faster!

Same here, wheels have gone out the window now in favour of BBTB and Zone chip.......
