Throttle Body Machining

[jdavis334]

Can anyone recommend a reputable machine shop to port and rebuild throttle bodies for an '87 GN? I'd also like to get my stock exhaust elbow ported. Thanks.

Jay Jackson does the t.b. mods. He machines them out to 62 mm, then bellmouths the opening. He then flares the back of the t.b. out to 65 mm. He has the parts to rebuild them as well. Do a search under parts for sale and you should easily find him. I hope to have him do my t.b. someday.

I emailed Jay last month about his TB and plenum mod work, he replied that he has had to discontinue his services and probably wouldn't be able to resume them any time soon either.

That sux. You can find them for sale on this board and on Ebay every now and then.
