Anyone have any pics of a STB on a TBI car? I want to build one, but can't think of a great design. I can build anything, but I need a starting point. Thanks

 

yeah ive been wanting to make one also

 

that would be awsome!

 

that's the best i could do for ya buddy.it's a MAC stb.TGO thread

 

That looks pretty good. I think I can build a pretty sweet one cheaper than $100. I have to wait until my motor is back in of course. Thanks guys.

 

Here ya go. This is Edelbrock's STB for carb & TBI Camaros.

 

That looks perfect. Do you have any pics of how the firewall side mounts up?

 

no I don't sorry. I'll take those pics for you if I have time later today though.

 

Sweet. No hurry its going to be a while before I do it anyhow.

 

Question.....

Those with TBI Strut Tower Brace....when working on your distributor...do you have to remove the strut tower to gain access to it and the spark plugs....

 

heres another shot not my car

 

shifty's car lol

 

I've got a few pics up of the one I made.. it gets me by for the $10 I spent on it. http://www.geocities.com/tzfbird/STBp.html

 

I'm curious of shots on how it mounts up to the firewall as well, seems like it'd be a bit weak.

 

The firewall is supposedly one of the strongest points to attach an STB to on third gen f-bodies.

 

Yup it is

There is a plate that goes on the top and bottom of the firewall lip that is sandwiched with 2 bolts. The strut mounts take the majority of the load and the firewall absorbs any torsional loading. It is actually really strong. 4th gens have a weaker firewall and can have problems with triangulation. I have put this car through hell when it comes to cornering and none of the bolts are walloed or bent.

 

heres the one i built for bout 20 bucks

 

..i saw this post then went to work and hour later out of a scrap peice of 4foot 1 inch tubing and two 5inch by 2 inch peices of flat stock i had a strut brace. all i did was measure the width cut the flat stock drilled holes for it,tacked a mig weld took it off welded it and was done.. except mine runs straight across the intake no bends nothing even goes under the air filter and clears it by 1/2 inch. solid as hell and works like a dream. all in the same day i put my wonder bar on. what a difference in stiffening this 12 year old car up.

thx guys

 

Does anyone have any idea if something like that edlebrock STB might fit around a stealth ram?

 

It won't fit. I am not even sure the TPI STB would clear either.

 

The HSR barely clears the stock hood from what I've seen. There's really no room for a STB above it, and you can't go around the front like a carb because the TB and intake plumbing is in the way.

 

Could it go under? As in, between the upper and lower manifold?

 

Not exactly. The HSR is set up just like a dual-quad tunnel ram, but with a TB on the front instead of 2 carbs on top. The runners are big, and take up almost all the space below the plenum. There's really no room at all between them.

It may be possible to run one under the TB, above the serpentine accessories, but it would be a VERY tight fit if it worked at all. You'd have better odds going over the top and praying the hood will shut.

 

Looking at my engine the way it sits right now, there is at least 2.5" between the upper plenum and the manifold. There is NO room under the TB though. The space between the front and rear posts or whatever is quite far back, so the STB would have to angle down and back. My thoughts are would it even be a benefit with it bent that way? Would the engine torquing back and forth during hard driving make it hit anything under there?

 

well your gonna want the strongest way .. if im thinking what your r i dont recomend to many bends kinda defeats the purpose i guess. but i would take a look at after market ones if i was you and go from there with your plans.

 

does anyone have specs on the stock and pipe sizes used on the mac or edelbrock setup i can get 24'lengths of steel pretty cheap was thinking about buying a length or two and making a wonder bar also

 

its very easy to make a wonderbar theres actualy a feew post on here about making them. i just bought one tho because there so cheap. do a quik search for wonder bar.

 

i know how to make them i just want steel specs on the stb and wonderbar like tubing size ect.

 

thats all i did with mine but mine its a little different because its carbed.


materials and tools i used:

sawsall
4foot of 1inch pipe cut ends to apropriate angle
flat stock mines 1/4 inch thick measure 2 w x 5 L
drill
bolts
mig welder
and an hour of your time.
you might have to bend the steel to meet your needs or make brackets to lift the steel up over your intake setup whatever it maybee.

 

Wow!...do they make those edlebrock STB's in chrome?

 

I'm pretty sure they don't.

But you could have it blasted clean then chromed.

 

Is a backing plate needed on the strut towers?

Or would washers be sufficient.

I think I've got all the stock I need for this. Might weld some up over the weekend.

 

as far as what Shifty said about the 4th gens and the firewall being weaker, if im not mistaken a triangular STB can actually crack the front windshield of a 4th gen.

 

Question: Would the Edelbrock Carb STB fit over Tall Valve Covers??? How much clearance is there between the 2??

 

Yep, talls are no problem with the Edelbrock..and niether are big blocks, take a look at these pictures

This is correct. Wheather it is true or not you won't find a 3pt STB for a 4th gen.

There is no backing plate for the strut mounts. You drill the holes and simple put a nut on the end of the bolt once you feed it through the hole. There is a backing plate on the firewall lip though.
