I took a few pics. just click on the small picture to enlarge. That tough part is the swingvalve. My swingvalve still uses the donut style flange.

The second one shows how close it is to the firewall, this picture was taken from above the p.s. resevoir. Feel free to ask any quetions. You won't regret this modification over the stock manifold.

ok so what i was thinking was putting the turbo flange on a *slight* lean so i will be able to use the stock SV.

You may have more room in a "g" body. Grab a manifold, buy or make a plate, weld it onto a tbi manifold and give it a shot.

i alredy made one but the flange was set back to far on the collector and believe it or not it didnt fit.

i have 2 more i'm gonna make and test out. both are gonna be a bit differnt from eachother just to test for clearences and flange angel. i wanna try to make one so i'll be able to use the stock SV.

maybe if one works out then venders will wanna copy my idea.

this a shot from the dodgegarage.
just for refernce to the thread. im going to making one up soon as well, though its gonna be fun in an l-body:)
i was thinking along the samr lines as trying an angle on the flange and such to clear the firewall and use a stock flange. i dont want to "massage" the firewall if i can work around it.

Do you think everyone else who has made one wanted to make their own swingvalve?

I'm certainly not the 1st to realise the swingvalve needs modification.

Here's a dumb idea.
Cut off #4 runner on the TBI and plug the mani there. Slash cut #1 runner (under #2) on a log mani and graft it to #2 runner on TBI header.
Downside is #1 and #2 share some runner ... upside is turbo is placed in the stock location.

I'm not able to picture that. Could you draw it out?

If you have both a TBI and a turbo log on hand lay 'em on floor. Turbo in front of TBI ... both exhaust outlets facing you.

By cutting #4 runner off the TBI mani you'll be shifting the header over one (1) port. ... ie. #3 becomes #4 and so on. Looking at the turbo log now ... you'd cut the #1 runner off but the cut would miter under the #2 inlet so you'd have some material left to mate and weld that section to the TBI mani at it's #2 runner (which used to be the #1 runner).

I figure I'll do this over the winter as well, as I usually start projects after Ray, then after he fails a few times, I get the job done. So I guess I'll make one over the winter

Turbo Mopars have run 10's on both "EFI" headers and "log" headers.

Garret
12-05-2006, 02:40 AM
That they have, but I think for a nice package setup the TBI one will work way better, plus the fact I am going for a low boost high HP setup using the right combination of parts

01-13-2007, 01:07 PM
Looking at the pictures, made me wonder, what is the problem with the log? Is it the fact that 1,2,3 all run together? Does it just need more volume? If 4 has its own 'path' is that why is runs hot (leaner)? What if the volume of the manifold between 2 and the turbo was larger (ie, cut the back out of the manifold and add more volume there, while at the same time adding (welding a 1/2 spacer flange between the current flange and the turbo (to allow porting to take advantage of the set-back from 2 to the flange? If an additional 1/2 inch 'depth' could be added it would increase the volume substantially and be somewhat transitional in volume between 1 and the turbo.

BadAssPerformance
01-13-2007, 01:49 PM
Yes, a log would need more volume and less restriction around "3 to work better. Turbo's Unleashed's log header does both of these.

I personally prefer equal length runners so that there is equal timing between the exhaust pulses as they get to the turbine wheel.

That's the most time-consuming part of this whole ordeal.

I hope the head in the picture is the same one from the car so you can do some test-fitting. But TOTALLY worth it.

its just a mock up head, i just finished up porting the head im using, about 10 hrs. worth. i think i have about 6+ hrs in the header so far, from the time i started cutting flanges to now. im sure ill have at least that in making the swingvalve and exaust flange. i also am converting my 525 to cable shift to make room for the new turbo location.
im ordering my 3 inch elbow and o2 bung tomorrow:)

shadow88
01-14-2007, 05:29 PM
I hoped you had the head off the car to make fitting the swingvalve perfectly.

I had to re-do mine 2 or 3 times to get the angle just about perfect.

Drill out the rivets on the can, rotate the can to your desired posostion, spot weld the can back to the bracket.

Anyone got any numbers as far as gains from running a TBI header with alone with a stock turbo and 2.5" SV?

I changed alot more than just an exhaust manifold to give a back to back measurment on it's gains.
It depends on where you start from. if it's resonably stock, the gains are "X"
If you have big valves and porting and huge fmic and fuel supporting mods ect. ect. I think the gains would be even greater.

Yeah this problem reared it's head after I had the TBI header on and found my small can wastegate was just not stiff enough to hold more than 19psi. I got a large can and went to put it on and the nipple pointed right into the firewall.

I have since then ditched TBI header in favor of a TU header.

That's exactly why I still have a small can right now.

If you wanna keep the small can.... drill a small hole in the actuator bracket, and another in the flat area just inboard of the hole where the swingvalve pin goes thru the actuator arm. Stretch an extension spring accross the span. This will effectivly raise the spring tension of your actuator, without limiting it's travel.

In reality, I don't even want that turbo anymore. It's still a stocker with lots of hard milage on it. It's got a good deal of shaft play too. It's time I get a super 60 and a large can. If I can make the manifolds I sure can make the large can work.
Thanks for the info.:nod:

almost done, not the best looking, but it should work. i have one area i need to trim slightly to clear the p.steering bracket. i have no angle on my flange(should have done more re-search, lol.) so its tight. i need to get the flange re-surfaced as it cooled too quickly, im still a welder in training:) it does fit and i have'nt had to do any firewall massaging...yet. i may when i convert it to cable shift, just for ease of swapping turbo's, all i have now is a garret. right now the actual outlet for the downpipe is around 2 3/4.

Click for larger picture. I know the welds are ugly, but that metal is thin. You have to be very careful. Very low heat to not burn the housing or the diaphragm.

I had a few people asking me "Why are you tearing that apart? You just got it delivered yesterday!" Only a few poeple understand why. :nod:
