Thanks again for the pics, Terry...
I hope my explanation over in the hotair section was clear on what I'm trying to do...
Right now, I'm running a prototype Terry Houston 3" DP for the hotairs...It is actually a Terry Houston upper mated to the lower section of an Action Fab 3" 2 piece DP...Kind of slick...One of the major turbo Buick vendors made it for me to see if it could be done...As of right now, my current headers(Poston's hotair replacement headers) are cracked and I need to replace them...The car is my only running vehicle at this time, so I can't really park the car and do the full conversion over to the 86/7 config at this time and I also don't want to replace the current headers with another set of 84/5 headers because I do plan on doing the conversion at some point and don't want to buy twice...If I can get away with piecing it together a little at a time, while still keeping the car on the road, I'll do it...I just don't want to get it halfway torn apart and find out that there is no way that the 86/7 headers will work and have to put it all back together again just to pull it back apart later to put another set back on...Confusing, huh???
I think that the ATR headers should work with what I'm trying to do...My DP goes straight down in front of the heater/ac box and takes a turn towards the rear right over the rear upper control arm bushing and from there back, I believe it follows the same route as all the rest of the DPs out there...It's just the area right at the control arm over to the motor that I have some concerns with...I will have to pull my a/c compressor off and make a new up-pipe from the exh manifold to the turbo, but I should be able to fab that up on an engine stand with a spare motor that I have before I install it on my car...
Those ATR headers look like they tuck underneath the flange that bolts to the head to allow a little more room for the crossover connection to come up and mate with the header at the v-band connection...Is that correct??? Unlike the stock headers which just come out to mate up with the main tube that goes to the turbo, right???
Thanks again for taking the time to take some pics...If I decide to do it and get it done, I'll post again with the results...
BTW, if you look in the hotair section at the top in one of the stickies, there is a link to BFH's webpage with some pics of my weird setup...Looks weird, but ran pretty good for as big of a plumbing nightmare that it is...
