Would like to know the difference between the professional products gsr & itr throttle body?

What throttle body is best to use on a b16a obd1, gsr or type r?

thanks

 

Honesty, I own a 68 mm profession products TB and I don't really know if there is difference between gsr and itr.

The TB I have those is pretty good. No sealing issues, no sticking throttle plate, etc.

For a B16a, I would recommend a 62 mm. If you are staying with the P30 manifold then I don't think you can use anything larger than 64mm.

 

ITR is the best TB to use if you use the GSR unit the bell crank for the throttle cable will pull the wrong way.

The main difference is the position where the throttle spring and cable attach, GSR cable attaches the opposite way as ITR. I used a ITR TB and ITR cable on my GSR after i installed my Skunk2 IM.

 

No, don't stay with the p30. I have a edelbrock performer x manifold and want to use the prof.prod. 65 mm tb.

 

Ok thanks, than I will order the type r tb.

 

The main difference is the GSR TB has a spot for the thing under the throttle body(cold start valve) and the ITR does not. I forget the actual name of it as I have never has one.

Thank is a nice combo.

 

ok thank man, you mean the fast idle valve. I don't need it, so the itr tb will be ok.
