JDM throttle body set up for 7m-gte from supracarparts.com

[SUPRASTEVE]

So I bought one of these a while ago. I like the concept, i like the response. The only problem is the throttle keeps sticking which i've never had a problem with the old linkage set up. On top of that don't buy one of these set ups expecting it to be polished like the picture they show. The one i got had cobwebs and it was dirty to the max. Nice little blue pulley though. In any case my question is has anyone bought one of these, and has the same sticky problem like i do?

-Steve Z P.S. If anyone wants pics of the set up in my car let me know.

Does it have an throttle stop? If you don't have a stop to keep it from completely closing, the throttle plate will wedge itself closed when you let off. The factory TB has such a stop, but if they changed out the bellcrank for (what I think is a generic) "blue pulley" you may have lost tat stop. Pics will help greatly : )

Cool I'll show you guys pics tomorrow after work.

Mine was shiney, no cobwebs, and clean, (but I didnt buy the JDM tb from them). All I bought from them was the throttle cable and a red billet pulley. I did experience the stickey problem.

Pics, please!

when I turn the pulley with my hand I can feel a lil resistance. I think its the spring. If so anyone know a way to make that spring move freely?

I can't really get a good picture of the lil cusion thing that the lil pulley sits on. The throttle stop I mean. But It does have one and it works really fine. when I push it down it will go up slowly I am sure that is working properly.

Why buy anything? I used a JDM TB on my car for several years with nearly no modifications, stock bellcrank and all. You don't need a pretty, shiny blue wheel to make it work, just a N/A throttle cable.

No, that little cusion thing is called a dashpot, and it is not a throttle stop. It is designed to gradually let the throttle plate come to its closed position on the actual throttle stop. When the engine runs at idle, the dashpot should not be touching the throttle linkage at all- vacuum should be pulling it away). What I suspect you feel is similar to that of a gun trigger's release feel- high initial effort, but once it pops it moves freely.

To be honest, I don't know if you can use that throttle bellcrank (blue pulley) and still have a proper throttle stop. One idea would be to delete the dashpot (not the best option, but a viable one) and then fab up a small plate that will bolt to the throttle body where the dashpot once did, but it now becomes a solid point that the adjustable screw can rest on for a super reliable closed-throttle position.

I will edit one of your pictures to show you what I mean. Gimme a few minutes..

404: throttle stop not found

 

[hvyman]

I do not get the point of this???

 

[Poodles]

To eliminate the linkage that sits over the valve covers is my guess, though I don't see why you'd need it for a JDM throttle body as they already eliminate that...

 

[hvyman]

Shits going to look ugly no matter what unless you have ffim...

The throttle feel with all that extra linkage gone is much better, so long as you set it up properly.

Any pics of yours, Shaeff?

Heh, somewhere. I haven't ran that setup in a long time, not to mention that I swapped to a FFIM and pulled the car off the road about five years ago. If you search my posts you might be able to find it. I'll do some poking around for pics, but I don't have long to look right now.

Edit: from five years ago, post #3:

A few minutes with a drill and a welder could make a very, very clean bracket for installing that setup

nice, I've been wanting to switch to NA valve covers since I went with Lexus coilpacks, and got rid of cruise control, and I was wondering if there were any alternatives to using a Cressida linkage..

 

[SUPRASTEVE]

Yeah FFIM for 7m is the best idea yet. So expensive and where would I get one. Also does it even pass california smog?

Only one that MIGHT pass smog was developed by suprasport. The intake doesn't have all the provisions it was supposed to have (EGR for starters). Not to mention suprasport's reviews...
