Throttle Body off a different car thats compatable?

[Mahonroy]

Hello,
I was just tossing around the idea of using another vehicles stock throttle body in place of the stock betta II TB and if anyone knows one that would fit, or with little modification (such as drilling new holes in the manifold to mount, or making an adaption plate).

I thought I had remembered a while back that someone said somekind of a stock mustang throttle body would fit, but I can't remember.

The airram intake manifolds opening is 68mm I believe, and there are tons of throttle bodies that look compatable with openings around that diameter (such as on e-bay).

I know the best bet would be to buy a BBTB thats made for our cars but the things run around 300 bucks were I could pick up a stock used TB off e-bay or a junkyard for under 50.

Also one last question I was curious about was if a throttle position sensor is a pretty universal device, in which all it does is send a 0-5 volt signal to the ECU which directly coresponds to the position of the throttle position. So if for example I got a TB for another car if I could splice the throttle position sensor wires together and have it operating correctly?

I guess if its not really a good idea, anyone got a used BBTB for sale lol?

But I think there would be somekind of a solution for one thats compatable...

Thanks again!

TC on nt used a a mustang TB for the tibs.

How big of a TB were you thinking of going? Your best bet is to just go to a Junkyard and find one that has the same kind of TPS sensor mounting location and just reuse your OEM sensor. Not all sensors are the same. Some go from 5-0volt instead of 0-5v.

does anybody know, without me going to the junkyard, if the TBs from other engines fit or could be fitted with minor adjustments( a custom spacer of some kind) onto the beta1 intake manifold? I heard rumours that the TB off Honda CR-V would do the trick? am I right??
the reason I'm asking is I'm planning to supercharge my beta1 accent!! and I need a BIG TB around...60mm!

What is the point of installing a bigger TB if you have the stock intake manifold?

The diameter of the intake port on the IM is still going to restrict your air flow no matter how big the opening is on the TB.

LOL

I have posted in the past regarding the maximum safe porting size of an XD IM, the XD2 IM is of almost identidal port dimentions so the maximum porting will be similar on both.


If you really want to get more power, you need to get your STOCK PARTS ported and port-matched to the IM.. This has shown to give noticeable gains to even a stock car. (tested it on my xd)

He's talking about a SC, so it's not the stock IM ...

Ok, good point. :eek:

Sadly TC seems to only work on the V6 units over there. and if im not mistaken they have a differant throttle body than us. some days it makes me want to cry. he makes great products....but none for the 4 bangers.

I'm not seeing how boring your throttl body would work too well, wouldnt the butterfly valve be a problem being as you cannot make that part bigger?

[Mahonroy]

Thats the thing that I was thinking. I would consider boring out the TB then if possible replace the flap to a larger diameter to match the boring. Only thing is I am not too sure how I could bore it out accuretly (using something for example like a dremel doesn't seem to cut it, as you can't get it perfect), and if there is even a place where you could locate a larger flap that could replace it....hmmm....

[ExemptedNut]

yea thats what i mean, cause I have an extra throttle body that I would like to bore out but don't know how

[Mahonroy]

Well apparently people use lathes to bore out throttle bodies which isn't such a bad idea, didn't really think of that. One of my good buddies is buying a new lathe within the next week or 2, so maybe I will try that out and bore the stock TB from 54mm to 58mm. Still working on locating a TB off a different vehicle as well...

[ExemptedNut]

can you explain a lathe to me? did you find out anything about the butterfly valve (flap)?

[bmxdad]

A lathe is a machine for turning a round object to a certain profile and/or length. Unlike a mill, were the tool turns, like a drill. In a lathe the part is rotated and the cutting tool traces a profile ... kind of like cutting a candle stick.

Thats a very simplified discription... but this should give you an idea on how its going to happes ... they'll mount the mainifold w/TB atached in the lathe chuck or jaws (Hope they have a big lathe :) ) Then rotate it with the centerline being the center of the hole there going to open up.

Thats one way to do it, but it might be easier to use a simple knee mill or bridgeport, and simply bore it that way ... setup would be way simpler and much cheaper to mfg.

[Mahonroy]

I should be able to just mount the throttle body by itself without the manifold attached right?

[Jonny666]

Good god. good luck mounting the manifold on a lathe.... ya deffinatly only want to do the throttle body. you make the new butterfly plate on a lathe too. Problem is the butterfly plate has to be slightly oval so that it seals up a couple degree's before 90. that's no problem to do if you have a jig. If your buddy is buying a lathe and he's got any experience running one he will have no issues with this. if he can't, any compotent machine shop should be able to do this without any issues. by the way. i thought our stock throttle bodies were 56mm not 54... are they truly that savagly tiny?

[KeWLKaT]

Wth?

All this time I thought they were 52mm....?

[jalmir]

yeah ... aren't they 52 mm ????

Holy resurrection!!!

I'm sure this has been covered but will a GK TB fit?

just reverse the positve 5v and ground. just measure the resistance to make sure it is 10k ohms (most all are)

i dunno why it wouldnt since its the same thing...

but if youre talking about the delta then i think the bolt pattern is kind of different...

(btw sorry for the edit it was an accident ;))
