ebay 3 bolt TB?
Anyone rock the ebay 3 bolt 85mm TBs? I was looking at the Jegs and summit versions and then ran across these. I dont need a 90mm or a 102mm as my ported stocker is fine really. I just ordered a new NNBS truck intake which as the 4 bolt 90mm TB opening I believe and also ordered a 4 bolt intake to 3 bolt TB adapter. I would like to keep the 3 bolt TB if possible and didn't want to mess with the shitty ebay 4 bolt TBs that everyone has issues with. Basically I dont want to run a larger TB with the $400 price tag as i'm boosted so its not really neccesary. The stocker is prob fine... but always looking at small upgrades lol.

Think the ebay 3 bolts would have the same issues as the 4 bolts? the Jegs/summit/professional products all look to be exactly the same as the ebay ones.

Maybe one of these? https://ls1tech.com/forums/sponsor-s...-ws6store.html I believe they've been selling quite a few without problems and the price seems fair. To bad you ordered the adapter already

The holley sniper tb use a diff iac motor that holley has. its $50 so basically $230 for a nice quality budget 4 bolt.
If you dont think a 90mm tb vs a 3 bolt plate amd 3 bolt tb on a tbss manifold wont make a diff just because you are boosted, you are mistaken. the transition alone behind the tb can cause all sorts of issues. why even do that?
The nick williams is $369 shipped as well. the holley adj cable bracket is $32 so still right at that price. you can use the stock 99-02 truck cable bracket with minimal mods also but using a high quality tb will gain you more than just hp. idle tuning and transitions would be vastly improved.

My new intake will and should have the larger 90mm 4 bolt opening which is why I was thinking about a 85mm TB. I wouldn't want to go higher than a 90mm as the intake will only accommodate up to 90.

So that $170 TB goes to $230 plus $32 bracket so we're at $262.
Well here's my reasoning. 1st the stock TB is reliabable and people with boosted motors have been pushing the stock TB to well over 800hp. You can't get an NA motor to 500hp with a stock TB. 2nd convience, I have 2 stock TBs, one ported and one not ported so it only cost me $22 for the adapter to run my current TB. 3rd and the main reason is that the stock TB has all the data in the stock PCM so the flow rates are accurate. If you step up to a larger TB there are a bunch of tables that change now and I have to tune them out which I'm no master tuner. But idle, startup, throttle transitions etc are all different bc at any given time the TB blade is letting in more air. The stock TB isn't really restricting me that much I feel but maybe as you said with the new intake the step behind could cause some turbulence. The only reason for the TB adapter purchase is so I could run my stock TB for cheap and get it running again without tuning for a larger TB.
I also forgot to mention that I run a 2004R so I have welded a tab on the stocks tB to hook up my trans TV cable. All the aftermarket TBs have aluminum cable cams so that's not going to work plus I can weld one I would have to fab a new bracket and prob drill and bolt some type of bracket down.

Holley doesnt make the iac. They will have it for a very long time they use it on their efi kits also.
We are looking for an aftermarket option for that also (bwd, smp, etc).
Your math is correct, and you can make well over 500 na with a stock tb...78mm or 85mm or 90mm cable or dbw.
