Huronspeed 4" bumper exit for v3 AC F-Body kit questions
Hey guys, trying to install this today with the VS Racing turbo linked below. It has the 1.25ar hot side. I removed the coolant overflow and trimmed the pinch weld at the frame rail. Its still contacting the frame rail though. I am using the recommended BMR K member and BMR solid mounts. Does anyone have any suggestions? I'm going to call them in the morning. Depending what they say I might try to see if it fits better with a 7875 Next Gen turbine housing.
This is not my car, but this is a Huronspeed fender exit and what I am going for. However mine is up about an inch relative the frame rail. I cut out the pinch welds and still have interference.

Here are some pics of what I actually have going on, thanks to my son for helping out. Its so close but I can't push the pipe up any further into the frame rail which would be needed to get the flanges to line up.
Subbing as I'm about to install the same thing. Mine will be mounted to a VSR 7875 billet gen 2.5, once i get the engine in, I'll be able to see more of what's going on under my car too. I'm running the non AC kit. Heres mine being test fit before i stuff it in the engine compartment.
Jon got back to me, he doesn't see any issues with how I'm installing. I have a Next Gen 7875 sitting here so I'm going to see if fitment is any better with it and we'll go from there.
Same issue with the other turbine housing so Jon @ Huronspeed offered to make the pipe fit my car for no additional charge if I can get it to him. I'm about 4.5 hours from him but going to try. I think its worthwhile so he can get a look at what might be wrong.
There is one possible solution without having to mod the pipe. If you space your transmission mount upwards slightly, it will bring the turbo downward and it may be enough to make it work. They build everything on jigs there, I can't imagine your pipe being welded incorrectly. Every combo is slightly different and it may be that your motor mount/trans mount combo is putting more of an angle into the drivetrain than whatever car they used when prototyping the pipe.
Your other option is to shim your entire K-member downward, which I've seen done in order to fit superchargers under the cowl. Or have a couple pie cuts placed in the pipe and welded back up. Either way, it sucks. I feel for ya. I just had to remove my intake and fuel lines just to plug in my oil pressure sender, I could NOT get it no matter how hard I tried.
I talked to Huronspeed, they are going to look at it and modify the pipe as needed for no charge. I've seen their custom exhaust work and it looks pretty good! So I am going to have them hook the pipe up to the rest of the exhaust. I am starting with a few pipes from an OBX kit but swapping for a bigger Borla muffler. Also adding a large Thrush, a 200 cell cat(swappable with a test pipe for tuning), a 7" Totalflow glasspack, two Vibrant Ultra Quiets and two resonated tips. Its probably overkill but I'd love the car to be stealthy quiet when the cutout is closed. The cutout is vacuum actuated so it will open as soon as I stomp the gas. I'll probably add a vacuum pump and solenoids later to hold it closed or force it to stay open.
Lots and lots of issues with Huron Kits needing a lot of tweaking and fabbing and cutting and grinding. From people I know who have installed them, they're not even close to a bolt on kit.
I dunno, mine bolted up perfectly when I installed it. My downpipe also fit perfectly with a stock K-member, but I have to do a different setup due to the UMI K-member I installed. I will say, my BOV would have hit my stock turn signal/fog light area because I have a Formula, but when I brought that to Huronspeed's attention, they made me a new one to my specs and even powdercoated it to match the rest of my pipes, free of charge.
Mine bolted right on with no issues. Even still have the little black box where the fender exhaust pipe passes by under the frame. Only thing that is a bit tight is the cross over pipe but leaving your manifolds loose helps before tightening everything down. They are one of the only few kits I see that don't use a flex in the merge pipe, so that can make it a little tougher to bolt everything together if you're not perfectly aligned. Manifolds had plenty of room. I will say i perfer my ICT 10mm manifold bolts over their allen bolts that didnt seem to have enough washers or werent meant to have washers... either way im not a fan of allens if i can avoid them. Passenger side is suprisly close to the shock tower and brake/fuel lines. You do need to slighly bend the brake lines out of the way. I plan on rerouting my fuel lines so not a big deal there for me. This configuration does allow running your alternator in the low positon which kight be nice for me later when i decide to get a compressor again lol Merge pipe is pretty stright forward. Again, its a solid piece, and no flex pipe. Definitely gonna hold up a large T4 turbo for awhile. This 7875 gen 2.5 sits pretty well on here. The fender down pipe is pretty stright forward too. I do wish the clamps were labled, either with a sticker or laser etched or something so i know which large clamp goes on what on these pipes. There are a few large vband clamps for im assuming various sized turbos but can be easily mixed up with the others. Their angled filter is a nice touch too. Moat would send a generic cone filter that "fits" but you get what you get kind of. Huron actually put some though even in hiw the filter fits. The pipes tuck up under the front a lot better than the cxracings kit. Heres when i was lining everything up. That black box under there... what is that? My exhaust still fits fine though with it there. As you can see, after some careful measuring, managed to not mess up the hole for the tip And after i installed the bezel and trimmed part of the hole, it lines up reall good.
