What brand/bore size throttle body would you recommend? I will need a good one in the near future when I get a dual stage intake manifold. Any help would be appreciated.

 

ericks is a good TB

 

JG makes a nice one, i think its actually JG eldelbrock (sp) now

 

Get an S2000 TB. In stock trim it's 66mm (4 mm bigger than the H22 one). I had mine P & P to 69mm.

 

what type of performance gains do you get from upgrading to, say, an s2000 tb? better response, increased gas milage, hp?

 

what do you have done to your engine? the stock throttle body is good to around 200-205hp. id worry about cams and intake manifold before a throttle body. all your gona do is kill the bottom end and loose your throttle responce

 

Reguarding this, I have a JG TB, and soon as I put it on, I am throwing code 7... (Throttle Angle) anyone have any idea how I can remedy this problem?

 

that might be the throttle position sensor

 

yea, thats what Im finding out from a very looong and not-so-fun google search. So it says the most probable cause is a defective sensor, or reading too hight or too low, but the JG TB comes with a new tps sensor attached so i don't think it is that, especially since i got the same code w/ a different TB on it.

Also, I only get the code when I am laying on the gas really had, (heavy accel.) I may try adjusting the throttle cable... I dunno, im clueless....

 

ya make sure that there is a little play in the throttle cable at off throttle and at WOT. there should be a little play if not loosen it a little bit and see what happens. if its too tight you can snap a cable.

 

I have a S2000 TB that has been bored out to 69mm intake 64mm manifold that I'd be willing to part with. PM me if you're interested.
