Intercooler Swap Question

[RSWORDS]

What are y'all doing with the throttle linkage and bracket when going from non-I/Ced setup to the I/Ced setup? I'm going with a 2nd gen intake if it matters.

[RSWORDS]

Anyone have a pic of teh intercooled throttle linkage and bracket?

I went with an all I/C throttle bracket and lines

I have done this recently and was actually going to post about this sooner.

You CAN use the non-I/Ced lines and injection pump with the I/Ced throttle bracket.
All that needs to be done is to notch the I/Ced throttle bracket SUPPORT on the head @1/2" deep so the REAR trio of lines will clear (PIC OF MOD SOON).
You'll also have to flip the non-intercooled intake around 180 degrees so the I/Ced intake air horn lines up to the intercooler pipe.

I was working on replacing the injection pump and lines on the burned engine I have here, and experimenting in the process.
The above is what I came up with to be able to run the non-I/Ced lines and pump on the I/Ced engine.
In addition to that, when removing the non-I/Ced bracket support, you remove 2 of the line supports/isolators.
You can cut up the old support bracket to make 2 line supports, or there are 2 specific ones from an I/Ced line set you can use, 1 of which actually bolts the support back into 1 of the original intake bolt holes.

Furthermore, when you convert to an Intercooled throttle set-up on a non-intercooled engine, you end up getting rid of that stupid, oversized throttle bracket SUPPORT arrangement that the non-I/Ced engines have.
That allows you to run the '91.5-'96 vacuum/power steering pump, which is also definitely an upgrade.
You will also need the I/Ced lower injection pump bracket, as it has an extra tab to support the rear of the vac/p.s. pump.

A person could actually weld this extra tab to the non-I/Ced support, too.

Oh, and FYI, the actual throttle bracket assembly the cable attaches to is EXACTLY the same between I/Ced and non-I/Ced first gens.

Pics of the set-ups.

Non-Intercooled:


Intercooled:


Non-I/Ced, I/Ced "Hybrid":


Modified bracket support installed:


Unmodified I/Ced throttle bracket support:


In the 4th picture, the one depicting the modified bracket support, you can just see the 2 line supports in place.
These are not the original non-I/Ced pieces, but the substitutes already installed.
Also, if you look at pic 3, you'll see the 3rd hole in the injection pump support bracket, this hole is the one used for the rear vacuum/p.s. pump support.

The only problem with using the IC'd style bracket that bolts to the lower side of the cylinder head and the injection pump bracket, is FINDING these odd ball hard to find IC'd parts. Most engines get sold complete and the seller doesn't want to part it out etc. I see nothing wrong with modifying the nonIC'd throttle bracket when using a stock 1st gen IC'd intake horn. But I don't have any experience with the 2nd gen style Bobbie is wanting to use. It might be hard to use the nonIC'd throttle bracket with it.

FWIW, the stock 1st gen IC'd intake horn supported Stomp's 680rwhp run and my lowly hp dyno runs. I do however agree for a towing application, the larger intake horn and IC tubes are worthwhile, JMO.

I just modified the bracket to work. Basically cut it off right above where the actual throttle bracket bolts on. Then add a tab to tie it to one of the bolts used with the IC style. I used a stud in the head to make it easier to take on and off. I can't say it has a lot of miles on it but plenty of throttlin' and it has stayed put.

Only had to modify the rear line holder to work with the top plate flipped. It used to have 2 isolators, but now has 1. You can see the 2 shiny spots where they used to be.

I guess if person is lucky enough to have extras of a "hard to find" part and comes up with alternative ways to use them, he's still wrong for doing so?
Cut and dried, if you have the parts, the way I did it only modifies ONE part, paves the way for installing the improved vacuum/p.s. pump and you can still keep the NON-I/Ced injection pump while running an intercooler.

I used 2 line isolators because it had 2 before, and yes, because I had the extra ones to use.

Where's the arguement for a very simple solution?

Mark, I'm not saying you were wrong by any means. I'm just saying for the other guy that wants to do the same thing is better off making what he already has works than trying to find a very hard to find part, 91.5-93 only.

Thanks Guys, I'm most likly gonna do like I always do, Drink a couple "beverages" stare at it... Bust out something to cut with... And have at it! Its worked so far on everything else!

[Remps]

You don't have to switch throttle brackets,just notch it out so you can fit I/C airhorn on,and bolt back on.(I THINK it would bolt back on if you did it right,I cut it off with a side grinder on the bend,and wedged the bracket under the airhorn)The manifold also does not have to be flipped,but you will have to run a bit longer I/C boot to reach the airhorn,and it rides pretty close to the brake reservoir.I like how the N/IC manifold is dead center,so I left mine.Just my .02.

Thats the CAN DO attitude we like to hear

Considering how the 2ndGen intake horn bends around on its own, it doesnt seem like it would interfere with the brake master cylinder like one using a stock IC 1stGen set up would.

I put a 12V 2ndGen intake horn on Rumblefish's pickup, and hacked off the brace on the front of the intake horn- seemed to hold fine at the time. Cant speak for the last year or so......
