3800 So I got this idea...

[imported_Ron Vogel]

Well, I've got a bunch of TB's on my bench, and was out having a smoke in the garage. I was toying with the idea of making a steel TB from scratch lately. I had some 3" pipe laying next to one of the tb's and thought, why not sleeve it? 3" tube is roughly 75 mm anyway. I'm thinking of sleeving a tb much like sleeving a block. Shouldn't be any big deal to do. The main problem with opening up the bore is the race for the throttle shaft. If it's sleeved, that's no problem. In fact, I don't see any real problem with going to 80 or 85mm. It'd have to be used with a LS1 maf, but it'd still be a cool little project. I just got a TB that would otherwise be junk anyway I'll try it out on. I'll have to pick up a stainless insert this week and check it out.

Sounds like a cool idea. Thought my TB may have come in handy.... Keep us updated on the progress.

How about some aluminum pipe?

The biggest readily availible is 3" and it's a little thin, or too thick. Plus since it's so soft it may collapse trying to fit it in snug. The other alternative would be brass, but it might be too expensive.

My father in law works at Central steel. I think he can get 3" UP TO A 1/4" thick. Im going to be getting some in the near future to fab up my TB relocation pipe.

Im also getting some 1/2"-3/4" aluminum plate for the flanges. I know I can get that. I guess you can mock up your first one in steel. You could fart around with the alum. later unless you have your heart set on it.

Happy tunes......

Ron what do you think the advantages would be with this???

The advantage is that you don't have to go through the hassle of an LS1 TB. From what I've seen the kits for it are a pain in the ass. Plus it's trick, I just like making custom stuff.
