Hi,
Is it possible to keep the 6 port actuators working and use a Holley?
Thanks,
Vin

SparkienSuggah

anything is possible, with enough money...
how are the six ports activated? you may have to make/buy+homebrew your own solution for it.

Hi guys ...
i have been use Holley befor its good i buyet all holly sistem bay 1650$ it's well geve U on 12A rotary 35 RWHP at least ...

the 6 ports are activated by the exhaust, so sure..

Vin

Ya, but someone told me to look it up on the forum because it had been done. I can't find anything. Can anyone suggest what words to search?
Thanks,
Vin

It is not worth the trouble.

Racing beat's kit delets the actuators.

Vin

I guess I'm out of luck.
My carb setup is sweet and simple and I don't want to let it go so I guess I'll either use TII irons or just use the RB intake for the six port.

dont give up yet! do you have a link to the service manual for a six port engine?
We have ways of homebrewing solutions here at Sparkie's Garage. I just dont understand the system that does the actuating, and when it should fire off.

Alex-7

They open from back pressure via a tube conected to the cat/presilencer.

You will not miss them when they are gone. I promiss.

Vin

OK, I won't give up quite yet.
Actually the only real problem would be frabracating the adapter plate, I think.
Now that I'v seen the system I'm sure I could get it to activate when I want.
But if I use the RB manifold won't I be doing the same thing with my secondaries? The auxillary ports seem to be like vacuum secondaries.
Oh well, any more suggestion?
Thanks,
Vin

I was thinking about the CAMDEN, but it's too much money.
If I could find a used one I would do it.

Save yourself money and headaches and stay as far away from Camden as you can. (Not sure why you'd even want to consider it). You could possibly find one of those sidedraft adapters that fits on the stock lower intake manifold. But the better question is, why would you want to ditch the EFI?

Vin

I don't have the EFI, the car came carbed.

the difference between the secondaries and the six ports is that the secondaries are vaccum actuated, and the six ports are positive exaust pressure.. if you have an rb manifold, am i right in assuming you dont have a cat?

if so, you may not get enough exaust pressure to force them open.
racing beat sells a header for this engine with a BP "pickup" tube
http://www.racingbeat.com/resultset....rtNumber=16128
i dont know if this is designed w/wo cat in mind.. email and ask (or of course, call).. maybe the placement of the pickup is such that exaust inertia generates the pressure without a kitty.
happy hacking.

hi VIN u can keep the stock CARB and make a open exhaust with muffler doom from the engen to the muffler withe 2,5" P it'ill give u 18 RWHP at least ... tray't withe MAGNAFLOW Muffler . . .

FB II

anyone get that?

SparkienSuggah

just part of the 700rwhp formula

2.5" pipes, turbo, stock carb. He knows more than we do.

Vin

So I've decided to go without the actuators.
I'm just getting the RB intake manifold. Now I have to decide what irons I want to use- 12A or TII.
Oh well, thanks for all the input,
Vin

unless you plan on fabbing up a entirely new intake manifold theres absolutely no point in keeping the actuators. the HP you will gain from the holley more than makes up for the losses of the airpump, etc.

if you are knowledgeble enough to be changing irons on a 13b, you shouldnt have to worry about this.

Keeping the aux ports ain't gonna happen unless you create a new intake by grafting the lower half of the oem lim to the upper half of the RB holley intake. The TII irons won't work unless the engine is an 86+. You will need to find the early 13B end irons from the 70's, if your engine is the original SE.

Your easiest bet, if you want to go 4-port, is to use the 12a end irons.

Vin

My car is an 1980, but the motor I'm swaping a 1991 NA.
What do think?
Vin

TII end irons are needed then, but I am not sure if there is a Holley intake made for the S4-5 4 ports, other than the J-Tech. The RB fits the 6 port configuration, not the 4.

You may as well keep the 91 as is, as long as you have the ecu, if not, you could go mega squirt, or haltec.

Like Trochoid said, the 5th and 6th ports are in the irons, and the actuators are part of the stock lower intake manifold (LIM).

RB sells an upper intake manifold (UIM) for webber/dellorto, that mates to the lower on 6 port motors, (not sure for 91), if you are stuck on carb. I think a couple guys on the 2nd gen have this set up.

I think the cheapest way to go would be 91 ecu, mods to exhaust, ignition , ect.
From what I've read on here putting the (89-91) UIM on 84-88 cars is an upgrade.

There may be more help for modding a 91 on the 2nd gen forum.

Vin

Fortunately RB makes both intake manifolds for the 1991- TII & 6PORT.
I'm not sure what I want to do. I'm thinking of leaving the motor the way it is and porting the secondary ports. What do you think?
Thanks,
Vin
ps. J-Tech (Jay-Tech) seems to be gone
