so i bought the 2.3tb (56mm) on ebay and the ebay page said ti was a direct bolt, so i trusted them and tried to do this in one night.. .clearly not working due to the number of vacuum line ports. (missing one...)
so one idea is a T. not sure i like that one.
the idea we've had here at the garage is to drill a hole and put the last sensor into a rubber tube and put the tube into the hole, then use "silicone gasket maker" to seal it in place... anyone have any advice/suggestions/responses to that? if it's a good idea, where should we drill/plug?
the other option is make a last minute run to the junkyard and get a HO manifold... but if i remember correctly that requires some modification to get it to fit the ld9 as well.... any help?
i searched around but there are like 30 pages of "tb" and "2.3 tb" etc and none of the results seem to be about fixing the vacuum line problem.
Alright, thanks. We ended up drilling and it looks friggin stock. Has anyone had any problems with the 2.3 tb throttle wheel hitting the ld9 intake manifold?? it won't even let the throttle plate close half way if you install the tb... we're filing the intake manifold down right now... anyone have any advice?
Dont file the manifold down, file the wheel down, or remove the wheel and turn it 180 degrees. (where the other hole will become the one for the Throttle)
How do I remove the wheel? It looks like it's held on by this little metal T that comes out of the whole assembly. If I do get it turned around will it still hit the manifold? We ended up filing the manifold down which helped but the cruise control's plastic hub where it mounts would still hit the intake manifold big time, and the throttle cables wouldn't even reach because of the wheel being upside down. Should I bother turning the wheel around if I plan on getting a HO manifold? I can't seem to find a comprehensive write up for those either.
Does anyone know why so many people seemed to be unhappy with the HO manifold and removed it? I'm most likely getting a stock ported plastic LD9 manifold so it's no big deal, just planning in case it doesn't work out.
If anyone knows a way to remove the throttle wheel to turn it upside down or has any ideas about how to make this work, let me know jdinneen@gmail.com
was the throttle wheel upside down on all the quad4 2.3 engines?
from what i've heard, you have to grind off that little metal "T" holding the wheel on, turn it 180 degrees then lightly hammer it back on, and you should be set

While searching relentlessly about throttle wheels I saw a few people who removed the HO manifold for whatever reasons. Don't know what my exact search string was now but if you check out "tb" "throttle" "throttle wheel" "2.3" and "ho" and every combination of those you could find it.
I'm torn about whether to contest the ebay item (they claimed it had all hardware and was a direct fit) and buy one at a junkyard for less, or just keep this one and modify the wheel.
uuummmm there's a great write up on how to install a H.O. output intake manifold on the new york J-bodies website,if you say you can't find a good write up i assure you this one will help. also if you are going to use a H.O. intake manifold,, get an adapter from Chris F it will make your life alot easier.

sorry to post again but thats the link to the write up

Alright thanks for that link. I knew that was some reason I didn't really want to do the HO swap, that seems like a lot of work. I'll just have a stock plastic manifold ported. I'd be more inclined to do it if I had someone experienced working with me but that write-up isn't terribly specific... plus there's a lot of modification. I think I'll just turn the throttle wheel upside down on this TB (it should fit and run just fine, no high idle right?) and get the plastic manifold ported.
Thanks guys.
If I were you I would just go to a machine shop and have them bore your stock TB to fit the 56mm plate. I did that, and even had it installed on the stock manifold for a while with no problems. Should only cost you an hour or two.
