My teg is slow, I know.....been thinking of slapping on a spoon TB cuz I messed up the oem installing one of those aftermarket throttle rotors. Twisted the shaft a bit...long story.

Anyway, I need to to replace it and I can get the spoon part #16400-DCR-000 for a decent price. I think that is the ITR tb, is it not? Can somebody please verify for me?

Question is will it fit without retrofit to my GSR? What is this throttle cable length/mounting reference I have seen posted elsewhere?

Question 2 any performance gain? Doubt much..........

Anyway as usual, thanks in advance guys.

 

#2) You will probably lose power.

The spoon throttle body is 70mm, which is way to big for a GSR with nothing more than bolt ons. You would need some serious NA work or forced induction to see gains with a throttle body that big.

With what you have now, you would want to stay stock. If you are thinking to upgrading your cams, and to a single stage IM (ala ITR) at some point, then consider a slightly bigger than stock one.

 

but my stock one is screewwed??????????

 

Buy another stock one

 

but another stock one is more than aftermarket,

duh?

 

Well you have a choice,

buy a spoon one and lose performance because you are not planning your powerband or your engine package

or buy a stock one (you can find them used you know) and not lose performance.
If you MUST go bigger, the ITR throttle body is slightly larger than the GSR.

GSR: 60mm
ITR: 62mm

if you do go bigger, you have to have your IM port matched, or it will create turbulence and again you will lose performance.

 

Planning.............well this block has 120K on it. So hmmmm save the 400 and save for JDM ITR longblock, with ITR TB, manifold etc.

F-it, just drive it as it until she goes. Actually this car runs decent as is.

 

If it's just the throttle rotor shaft that's messed up, you might be able to call the dealership and see if they sell just that part....or you could call up RC Engineering and see if they could repair it, and while they're at it, you could have it overbored for a lot less than a new OEM part or Spoon TB....Hope this helps....
