does anyone other than gude performance make ported throttle bodies for the tc?

 

Back when the tC first came out and performance parts started to flood the market Alphawerks had a throttle body they were working and trying to release for the tC. I believe they sold one but it was never publicly released due to CEL. After porting the throttle body and installing a new bigger butterfly valve it would cause a CEL stating incorrect angle of throttle plate. I spoke to Alphawerks several times on this as I wanted one. The best thing to do would be to have the throttle body bored out from top to bottom turning it into a velocity stack therefore you wouldn't have to worry about issues resulting from installing a larger throttle plate.

 

that is the same issue we are going through with the Yaris TB........people are using the one from the xD to replace the stock one,so far a few people have gotten it to work and with no piggy back it is keeping car running smooth after it warms up.

Is there a throttle body that will fit on our motors from another toyota motor that has larger body and butterfly.?????

 

i remember an old thread that says the RX8 TB is identical to ours but 70mm, same connectors and everything but i have yet to hear of anyone that has done it.

 

I'll have to look up pictures of an RX-8 throttle body.

 

how many mm is our stock TB ?

 

55mm.

 

I cant find any close pictures of an RX-8 throttle body. I'll have to see someones.

 

I will keep everyone updated i'm looking at a rx-8 tb sometime this week. If it looks like it will fit ill try it out.

 

I remember seeing that before as well but don't recall anyone actually doing it. I'll ask the shop with my car to look into this if I need it, because they work on a lot of RX-8's.

 

Also keep in mind it could hurt you unless you have a lot of supporting mods with it.

 

..

 

This is a RX8 TB ported and polished

 

I have I/H/E and light crank pulley. after the tb im looking at getting the wr intake mani. then get tuned.

 

is the one on the right pnp?

 

No the one on the right is welded closed to have a smaller bore.

Sorry I had to and yes.

 

lol ok.the picture would be much better if it had been taken looking down at both of them so you get a better idea of the difference.

 

You guys should also look into the throttle tune from World motorsports, It gets rid of the electronic delay and makes the throttle a lot more responsive, like a cable.

 

Everyone thinks there is a electronic delay even if there is its less than a second, the problem is the engine response which can easily be fixed with one step colder plugs, lighter flywheel, and tuning.

 

I thought the delay wasn't that much either until I put the throttle tune on, it made me a believer, this was after I had my car tuned to.

I am interested in a port throttle body to, has anyone on here tried gude's?
