M20 Individual Throtle Bodies

[Kos]

i have got some but it was that long ago i took them on 35mm film!! got to scan them first but i aint got a scanner!!
the car i snow in bournmouth. i did too much to it and in the end i broke it to get money back!! one guy too shell and some one else the running gear. it was all in cecotto shell, convirted to RHD, 3.0 s50 enginr 5 speed box, and a mental spec really. got it up and running used it fot 2 months then got rid, too many of these convirsions are popping up now so thats why i tooks dips M335i turbo, it faily uniqe as its a turbo and an M3 and got loads of potential, i helped build it so its not some one elses work and i can put my name on it together with the other involved.

Ah, 35mm film. I remember the days when.......

Would be good to see the pics if you can get them scaned. Must of been one of the first?? Sound like a nice spec as well.

I think he meant, 50bhp if you run TBs with other mods he mentioned.

[E327UKL]

i enquired about webers on my 2.5 as it is reletively inexpensive but all the racers who was running carbs that bexleys put me in touch with all said about 10-15 bhp, possibly 20bhp with tbs

[Kos]

spot on mate
50 with all mods and tb'b
mind you BBR about 10 years ago had a a head and cam conversion which was supposed to give you 246bhp, head cam, chip, manifold and system and a bigger single tb. i would question it, they have one hell of a reputation of builing some quick cars!!
m3 with s50 was ok, i bit tatty to look at but the guy who took the shell of me has gone for a 3.2 with 6sp box and more trick bits and full restoration, its awsome now !!

There is a set of M5 throttles on german ebay

[Widge]

Don't think they would fit an M20
And apparetly a bugger to fit to M30's

[Stevin]

I could make them fit... just need someone to buy them for me

[Emotechnik]

FOR SALE


Throttle bodies with fuel rail + fuel lines and the six black inlet trumpets from a E36 M3

PM me any Offers?

[Jhonno]

e36 ones would need alot of work to fit if they would at all..

better off with the bike ones imo, cheaper as well

[Turbo-Brown]

YAY!!!!

Behold:



Just need the bracket for the throttle pot, and fuel rail and they're done!

(also need to drill for the injectors and also fettle the other TBs to fit)

[Widge]

So you still have a fair bit to do then

Looking good mate, are these the ones you were turning butterflies for?
And how are you going to get the injectors at the right angle?

[Turbo-Brown]

Looking good mate, are these the ones you were turning butterflies for?

Yeah I know Still, was a boost to get them hanging off the head

They are indeed the ones I was making the butterflies for. The real laborious bit turned out to be making the spindles for them though, seemed to take forever to machine a slot in each one!

Planning to cant the bed of the pillar drill over at 40degrees and then drill the injector holes from there. Tis a bit nail biting as after all this work, I really don't wanna booger it up!

[Widge]

So at 40 deg do you recon you can get the squirt from the injector to hit the back of the valve head? Like the original manifold? Or is that not really that important?

[Turbo-Brown]

Sorry, meant to put 45degrees.

Either way, that should see the injectors in pretty much their original position so with any luck, the emissions and low speed drivability should be pretty good

[Widge]

I haven't got a clue what angle they are at mate
I was just wondering what the hitting the valve heads had - and as you say emissions and tractability, as long as the fuel goes in I shouldn't worry! You are turboing it afterwards, right?

[Turbo-Brown]

Just got a couple of injectors mounted

[Widge]

Nice!

The injector tubes look like they stick a long way in to the bores, good angle though,....I think Like I would know

Good job mate, makes me want to get on and build my engine now!

[jon_volk]

I chose the bike tb's b/c they were so cheap. 38mm is more than adequate for an n/a m20. I think youll start loosing torque with anything much larger with minimal top end gains.

Heres a quick video before finishing my exhuast.....dont mind me missing 2nd gear in the first run....the shift knob fell off

(edit, forgot the link) http://www.hassturbo.com/video/BMW/E30.mpg

Hope ya like, cheers!

Oh, the TB's and Megasquirt to control fuel and ignition cost a whopping $550

[keggy]

wheres the video?

[Widge]

That's a wicked setup Jon - wheres the vid I can't wait! - hope you realise you have given loads of people the inspiration to do ITB's.
Do you have any recent photos of your set up?
Cheers

[jon_volk]

Oooops, sorry about that.

Forgot to post the link, too many beers will do that

Ill take some new pics when Im at work on Monday.

[Widge]

That is sweet - all straight sixes should sound like that!
Keep up the good work!

[chu346]

It does sound like a motorbike!

How does it feel/perform?
