somthing like this
[url=http://www.jenvey.co.uk/~Bodies1.htm]http:
im sure a man like me can make something like this from what i can make out it's a tube with a throttle valve and a injector behind it?
must be easy

Hey Steve, that's great news...I'd been aware of Megasquirt for a while......they said ignition would follow later.....looks like it
has...
Great stuff indeed...

ok im geting very interested iv just spent the last 24 hours thinking of megasquirt (very sad i know) and looked at all th info i can get hold of on
it and it is looking good in fact it is looking very good i think with a bit of thort i could get more power out of this system then twin 40s
just need to get it working and i may have some twin 40s for sale 
i am runing a 1700 xflow stage2 head and a 234 kent cam is there eney one whos thinking the same as me?

I was thinking of somthing like this  should'nt be to hard to nock somthing up
 
xflow-tbs
Ill measure my twin 40s up and copy the bores and throttle valves then put a injector behined it.
for the trottle position i will remove a throttle sensor off another car.
sounds good to me i will have more power,more driveability and even beter mpg
ok the only thing that may cost is a cheep lap top dose not have to be top of the range just has to run win95 but the quicker the better any
suggestions?

CCC did an article about DIY injection a few years back. They use old 40DCOE's as the throttle bodies. The ECU they used was Emerald (because
the guy writing the article is a partner in the business)
Don't throw those 40's away Rell
If you could come up with a way of simply fabricating the whole lot for ŁNo, you'd generate a lot of interest.
BTW, there's a chapter in Ron Fournier's "Sheet Metal Handbook" where he makes an inlet manifold for some V6 or other from
sheet.
Cheers,
Neil.

im prity good with my hands and have a lathe in my garage to make the bodies.
i was thinking of useing stainless tube with bits welded on then machined.
i think the shaft for the trottle valve will be the hardest thing to get right because im sure i read some where that they have to be just off center
this is why im copying the twin 40s valves. Is this right or not?
just had a thort i could use the valves off the twin 40s
i can get everything else in need from a scrap yard
trottle position senser
lamder senser (fits in the exshort to momitor the oxigen content)
air temp sencer
water temp senser
and injectors
i just need to know which one are compatible with the megasquirt system
so hopefully i can do it for very little money

Interesting...
I too have a lathe in my garage (1963 Colchester Bantam), although I'm not particularly good with it. If you come up with some designs,
I'd love to see them. Who knows, I could even have a go at making some myself.
Best of luck,
Neil.

looking at your piture it looks that your useing a wankel engine and i have been looking at the posts on the yahoo forum and there is some one on
there useing one on his wankel engine
megasquirt can also deel with turbo systems.
what engine are you useing not a 20B i hope you can get over 900bhp out of one of those
if your useing a 12a engine you can still get 200bhp with a good power curve
and for the 13B about 400bhp with a good power curve but you can get 600bhp and the best thing about the wankel engine is it ways about 1/3 of the
wight of a piston engine(even if the engine has a alli block)
GOD I MISS MY RX7

I'm v interested in this as well, and I'm a wankeler...
I believe Glenn is building a 13b turbo using two megasquirts. Not sure how he's getting on.
I was thinking of just taking the easy option and going with the standard injection to just get the thing on the road but if we can collaborate on
this and get something going. There's a guy called bill on http://www.mazdarotaryclub.com who's
got a 13b westie, I know he's looking into using bike throttle bodies and megasquirt.

Vertical Throttle body/ies
Why cant you fit a single or twin throttle body to a downtraught weber type manifold.
I've seen this on a site related to the Megasquirt stuff.
What throttle bodies would work for that .
Could be a single 40mm or something..
Any ideas.....
My engine has already got a water temp sensor ,air temp sensor,and a lambda sensor.

Excellent post ! Thanks for the sites.
I've been looking to do something like that for years but have been too busy.
The whole thing looks very simply organised and a doddle for anyone with electronics knowledge to build.
Looks like I'll be sending off for partial kit soon.
Twin 40's have been used as throttle bodies before. They don't have to be in good condition either, you just need to fabricate a
manifold.
Have just looked at number of 'posters' a month on the Yahoo site. Wow, close to 2000 a month average, that's some interest!

dave i think you mean something like this
 
plenum
the only thing with doing it like this is that it dose restict the flow a bit but it would be easyer to make
but as said by by GO you can get bike thottle bodies that work very nicely iv been told GSXR600 bodies go on a xflow engine with a home made manifold
with good results.

I meant bolting a throttle body vertically on the standard manifold , but with the injector in the throttle body not individually in each inlet
tract.
Could that not work like a carb ?
But with realtime adjustments going on?
Excuse my simplistic ideas but I'm not very up to speed on Injection.
Can you tell me why what I propose would not work?

yep sorry mate it would work
you will need a good tig set to weld a lug on to manifold for the injetors.To weld alli properly you need a tig set with ac on it. if you've got
one fine but if not go to a fab shop and thay will do it for you (just slip the man a tener)

If you fitted a single bike throttle body vertically would it not have the injector built in the body?
I didn't want to do anything technical like putting injectors in each inlet tract.
Or are the injectors always separate from the throttle body?

there ar two things to consider
1)you could not use the standed injector you would need a masive single injector and this may not fit in the bike throttle bodie
2)it would be a lot less efficient probably a little more than a carb and have very little power gain
all in all i do not think it would be worth it?

ok done a drawing on autocad to get the jist of things it is only a guide line and i know the bore is only 34mm but it is the only stainless pipe i
can get hold of at the min
but on my stage 2 head the bore in the head is only 31mm so it may not be to bad
any Suggestions are welcome and i know it will be very difficult to line all the bushs up some coments on this would be nice

I dont know how to
but if you what a copy of auto cad you can download it from kazaa.
www.kazaa.com
just put in autocad 2000 or 2002
and download it make sure it has the crack on it or the code
