56mmTB ONLY FOR 1998-2003

If you look at your TB you will notice it is intergrated into the upper intake manifold.So basicly this was the only engine GM (don't know why they even did it) pulled this trick on(93-97 2.2's).The only option is to bore and sleeve the upper manifold/tb unit.RSM sells a stock unit bored and sleeved for $200(after core return).

The one on the bottom is the RSM unit

[truckinjeff]

Are there any other companies that makes 56 mm throttle bodies for a 96 2.2 liter other than RSM? RSM wants over 260 dollars for their intake.

[Stinky]

Yeah,Mantapart.But they want $500! Its expensive because you have to sleeve the inside of the TB because the IAC holeis so close to the TB main opening.They have to be kept seperate.

[truckinjeff]

Wow thats too expensive! What about an intake swap? Are there any intakes that will swap with a 96 2.2L that I can pick up from the junk yard, maybe from a newer 2.2 liter s10 engine or a 2.3 liter grand am engine?

[Stinky]

Not that i know of.Even the 98+ manifold isn't a dirrect fit.

[Stinky]

Yeah the Mantapart one uses a custom upper manifold"airbox" and converts to a removable TB.They use their bored quad 4 throttlebody.

[rantz and raves]

alright well i got mine installed today and besides the problem i'm having with it sticking like when i hit the gas a bit and the rpms go up to about 2000 it doesn't come back down... hmm vac lines? the reason i'm posting is to say that my exhaust definitely sounds louder with this. i think at least

that's what i did.. having a problem with the truck returning to idle tho =\ i think the butterfly is dragging.

[whatdatruck]

I noticed there are 3 different vin codes for a 93 Grand Am. Is there any difference between the t-bodys on these or will any of them work?

You will also need 1 small 10mm by 1" long bolt or you could drill it out and have 3 bolts holding the TB on. The removal of the current TB is straight forward and will require a 10mm socket or wrench, and a pair of needle nose pliers to remove the vac lines. Then the 56MM TB just installs like the old one. just make sure to attach the Throttle cable on before you try to bolt it back up, it makes it alot easier to hook up. Use 2-3 of the TB bolts that you took off the stock TB depending if you drilled out the hole or not.
You will also use the stock throttle cable bracket.

One thing to look out for is that if you have cruise control make sure that the 2.3L TB has the nub for the cruise cable.

Will leaving the FBR vac line off mess anything up? If I connect it into the other vac line won't that take a way PSI from that line and maybe mess something? (sorry idk much about vacuum)

[2wdsten]

I have a 2003 s10 2.2, and I also have a TB of a 91 Cutlass Calais 2.3L Quad Four will the two mesh?

If you are experiencing problems with RPM's not dropping when idling, be sure your gasket is completely sealed. I had this problem.

If it is a new TB, (not just a crappy spacer like mine) be sure your throttle cable isn't sticking.

[What?]

wouldnt really worry too much on gasket on TB, i dont think i got any, as long its tighten down properly then no biggie

rantz, u got vac. leak, look at hosing again, did u put 2 hosing in t connector that goes into the TB? or look around at the hosing, possible rippd hose n started leakin, etc

[What?]

no, not hookin up a vac line will increase fuel PSI at idle, which is waste of gas

that will work fine, same motor, different vehicle

[blackfire7]

I just got mine on today from a 92' grand am.. I cant believe the boost it gave it.
I was wondering if switching the throttles gave anyone better gas mileage? Just wondering..

[What?]

with 56mmTB swap, i didnt see any better mpg, neither did few other members i kno

[CubanSDime]

where can u go to bore it out?
and for an average of what price?
can u do it your self?
what tools do u need?

[2.2L Sonoma]

hey everyone, just wanted to post saying that i installed a 2.3l TB onto my truck today out of a 95 grand am. Everything went on surprisingly well aside from a problem i had with my throttle and cruise cables mounting up. My stock bracket off my truck seemed like it was too far away from the TB, in effect pulling the butterfly open to about 1/4 WOT when mounted. I was concerned about this so i fashioned up a POS mount for the two cables. It works, and my pedal position is ok in the cab now, i was just wondering if anyone else had a similar problem when doing this. But overall i am EXTREMELY happy about the little boost i got from it. Through 1st and 2nd gear it really pulls hard (in my eyes a very good mod for the top end greater than 4000 rpm). I also got an E-fan today and plan on slapping that on tomorrow (though i couldnt get the clutch fan off! tonite!) . $50 for everything, i was very happy.

Have a nice day,
AJ

[2wdsten]

I went to install the TB off from a '90 cutlass calais onto my '03 s10 an I had a few questions. I got these questions just by looking at it not trying to install it. (it's my daily ride to school)

1. How do I hook up the cruise control cable.
2. On the bottom of the TB there is a black plastic what looks like 2 hose connections. What do I do with them? Plug'em, or are there hoses that fit into them.

Thanx for any answers.

[2.2L Sonoma]

Hmmm....if you could...attach a pic to a reply and show me what you are talking about in referance to the bottom of the TB...as far as hooking mine up it bolted right up with no problem...though i talk about cable issues in the post before yours in this thread.

your cruise control problem could be a result from the '90 olds not having cruise, itself. There should be two separate areas to hook up the cruise and to hook up the throttle cable from the pedal. In a way you could probably rig up the cruise to work....but i would recommend selling the '90 Olds TB you have right now and going to a yard and getting a TB that has the cruise control on it (that is, if your '90 olds TB does not have the extra hook up)

Lemme know!

[ablues10]

does it matter if it is SOHC or DOHC?

[Zq-8_dawg]

I would have to be a 2.3L quad 4 which are all DOHC, the 2.0L SOHC will not work.

[2.2L Sonoma]

hey guys...its been a few weeks now that ive had this TB on my truck. I notice a little whilsling of air or a turbulence noise at about 1100-1500 rpms. Also, i kind of notice sporadic hesitation when i get on the gas (from about 2000 to 4500 rpm). Does anyone know what might be going on? i think this weekend im gonna take the TB off again and see if i can realign everything. all in all it seemed like the truck ran better right when i put the TB on and now that its adjusted itself, runs slower. but then again i might just be used to having a slow 130 hp truck as opposed to a slow 125 hp truck.

I also had that high idle issue at startup, but things seem to calm down after the truck runs for a minute or so.

later!

I am just wondering if anyone figuresd out how to get the throttle cable to work properly. I can't find an adjustment on the cable. I thought all throttle cables had an adjustment of some kind. For the time being i just drilled a hole in the 56mm TB plastic roller that the cable resides in and let it go. So far so good but The pedal in the cab is definitely shorter than it was with the stock TB.

Thanks
TJ

unfortunately i never found an adjustment on the cable either. I kind of rigged up a sloppy cable mounting system and now the pedal is normal in the cab. Basically what i did was put the little ball thing on the end of the throttle cable on the TB where it would have originally gone...then i just moved the part of the throttle cable that has the protection around it to where it appears natural in how the exposed cable part is not under any tension. with that i put two small small hose clamps (the ones that you can adjust with a flathead or hexhead) on the protected part of the cable either side of the cable mounting bracket to hold it in that position. then i taped it up to counter any annoying vibration (i could hear a vibration without the tape and now its gone with it). I have yet to devise a more secure way of holding the cables still, but this works and has worked for the past few weeks with the pedal at normal position in the cab. repeat the process for the cruise control...hope this helps!

AJ

[project_angel]

i just got myTB on this morning, i had a little problem with the cable length, just use a hose clamp on the driver side of the TB bracket and pull the throttle cable till its snug and tighten the clamp all the way down
i still cant believe the amount of power i got out of this mod next up im doing the efan

You cant drill that out and have 3 bolts holding it on becuase the bolt holes dont line up! (i have a 95 grand am throttle body) i drilled that bolt hole out (the top right one correct?) and after installing the top left bolt and the bottom right bolt , that bolt hole does not line up with the hole on the intake manifold you can only have 2 bolts holding the throttle body on the top left and bottom right bolts is 2 bolts enough to hold the tb on?

[What?]

you may have drill it off, thats why alot dont drill it and just bolt on with 2 bolts, i have used one bolt to hold my TB for almost 2 years and drive hard at times, light, offroading, it still holds

[bladehines]

Just thought i would add that a newer 2.4 uses the same gasket as a 98-02 S10 thottle body. And the throttle body's are not the same. I don't really know what the difference is, but the GM part numbers are:

17113620 for a s10 throttle body

and

17113632 for a 2.4 cavi throttle body

The pictures look just alike for both throttle body's but it doesn't give me dimensions on the opening itself, so i don't know?

[bladehines]

just wanted to know if anyone has ever tried to mess with a mid 90's 3.1 throttle body?

i am getting one for free so i am going to mess with it and see how close it is to the factory 2.2.

[What?]

Different part number for different vehicle since same motor but the VIN still dont match up and less confusion

Good luck with the 3.1 swap, hope turns out good BUT whats the size? Stock 2.2L is 52mm

[bladehines]

stock 3.1 is ALOT bigger here is some pics of the two.








edit:::::::::::::::::::::::

i did some research the 3.1 and the 3.4 are 56mm throttle blade openings. but as you can see the accutal opening is alot bigger.

the only thing is there are no vaccum lines to connect to the 3.1/3.4 throttle body. so i am thinking you will need a throttle body spacer with some fitting screwed into it for the vaccum lines.

[bladehines]

another good question?

has anyone messed with a newer model 2.4 engine to see if you can use the throttle bodies off of them, or if they are bigger?

i know the gaskets are the same, the tps, and idle air valve are the same.

so i am not sure about the opening though?

edit:::::::::::::;

After doing some major searching the newer 2.4's use the same throttle body exactly, same size etc...

so no help there!

[bladehines]

here is a link to modifiing throttle bodies even more. i thought some of you might like to try this.

i am going to be doing this with a 2.3L throttle body.

Throttle Body Porting

[bladehines]

well i have the same problem with the idle deal! i put on the throttle body and it idled real high. adjusted it and idled to low and died so i took it off.

i am going to put the cavi intake on and do something about the throttle body. maybe sell the 2.4 throttle body and get the RSM one. i don't know yet.

[bladehines]

another question my cable hook up is totally different on the 2.3 quad throttle body compared to my factory throttle body!? anyone know why? and looking at the pics on this link mine looks totally different!

http://www.s10forum.com/forum/f105/tb-install-151707/

[tsayyote]

Just did this today. Thought i'd snap some pics during the process.
This was the TB i used: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=018&sspagename=STRK%3AME WN%3AIT&viewitem=&item=280109143570&rd=1
1992 Grand-Am 2.3L SE.
Sorry about the pictures, the camera was set on the wrong exposure.

1. Took the intake and stock tb off.


2. Arrows mark which two screw holes were used to hold the new tb on.


3. Difference in size of the throat. Stock tb butterfly valve placed over Grand-am tb.


4. Difference in the plastic that the throttle cable hooks to. (Don't try to switch them, I tried it and the butterfly valve stays about an 1/8 open when I took the stock plastic and put it in place of the Grand-Am plastic.


5. A brief look at the vacuum connections.


6. I didn't grind anything down, I just put the throttle cable in the plastic and it holds fine. (Gas peddle is even in the same spot, didn't move closer to me).


7. Be very careful when moving this vacuum line. It is not a flexible line. Mine snapped and I had to attach it a different way to the Tee adapter.


8. A finished product. Power gain was noticeable.



Info not pictured: Tee the two smallest vacuum lines together and attach to #3 as shown in picture 5. I went to kragen auto parts and bought this: http://www.partsamerica.com/productd...goryCode=4016C
You will need about 2 inches of non collapsible rubber hose (not fish tank tubing) to attach the Tee adapter to the vacuum connector on the TB.

I had to make sure that the TB was lined up a certain way when I was tightening the bolts because the butterfly valve hit the inside of the manifold when it was fully opened. This was corrected by loosening the bolts and re-centering the TB. Mine stuck on the inside of the manifold and wouldn't close causing my truck to red line for about 5 seconds before I shut the truck off.

Clean the Tb with some sort of cleaner (I used carb cleaner like others said to use) and also I used white lithium grease to lubricate the bearings that open and close the butterfly valve.


I didn't notice a change in the throttle position. My peddle seems to be in the same place and goes to the floor like before.

I also didn't notice a change in rpm's like others stated. Started right up, idled at 900-1000. No problem at all.


Hope this helps others out.

[robertlamont80]

If the throttle bodies are so close maybe the tps sensors are interchangable? I just put a new one on the truck!!!! Any one try this yet?

[snafoo]

I just bought a 56mm TB off a 1992 achieva 2.3L SOHC quad 4. it wont matter about DOHC OR SOHC right? according to the chart there is a 2.3 OHC which i assume is SOHC.

I went ahead and tried. Install went fine. no problems. noticable power and it sounds better

yes,they are interchangeable, i didnt have to since the 56mmTB was ok, but i had stock TB in case if need to swap sensor when it goes bad but just clean out with brake cleaner 1st if that helps, its usually dirty and clogged

[2002dime]

someone has a listing for a 56mm mantapart big bore...100 bucks right now

http://cgi.ebay.com/ebaymotors/Manta...spagenameZWDVW

But here's the ones i want to get for the s10, i don't know if it will work though. I know the sensors has the same pincounts but they are in different areas. Plus there are only 2 big vac ports at the bottom. But i think overall i should work.

i wonder what size the bottom TB is, its from a 3.1

[Camwi_003]

Hey guys quick question.

I got my TB yesterday and it didn't have a TPS so I got one today for $10.

But my TB has these Weird Metal lines like for a smog emissions type thing or something...

Any idea that the heck this is?

I'll try to post some pics in a few.


Thanks.

[Camwi_003]

Ok, heres the TB,





And I'm hoping this is the right bold pattern,
