I didn’t know that he passed away.Years ago at TSTSNBN
Years ago at TSTSNBN, Gonzalo Duque was making these for the MN-12. He passed away and I'm wondering if a family member picked up making these.
Ok, poked around on the website and his son took over the business.

I feel like I've heard about a shop that used to port these. So it has been done, but not sure how many have done it without the rest of the portingPulled the engine today, what a filthy task with 27 year old gaskets GROSSSSS
I noticed the exhaust manifolds have a lil extra lip on the inside that could probably use a lil porting. I’m sure it won’t make huge difference but I’d sleep better at night. Anybody ever do that??

plus supercoupeperformance didn’t have any in stock til mid year. This will have to do for now.
RIP, Tbirdbrain. Anyone heard from michelle? I have a set on the red cougar.Preston Smith (RIP) used to port them back in the day; I had a set which I sold to @CDsDontBurn after I installed long tubes. It certainly helps with raw flow potential, but remember the best thing you can do with the exhaust is build it for improved scavenging - focus less on flow.
Ahh, that makes sense he was able to ship my 4V headers out ASAP. You can get them in by dropping the K member too, that’s what I’m doing@XR7-4.6 bill said he had 4v headers in stock except the 2v. I really wish I could have got them, maybe put em on my credit card and paid em lil by lil. But he didn’t even have them in stock til later which sucks since I’m sure the only was they go in is by removing the engine huh, sucks. Anyways this will totally have to do for now![]()
A ratcheting 18mm wrench is my special sauce.
You can unplug those for the time beingI have one. You can see it in the first picture.
The problem is range as I have none.
What's the secret sauce to getting this arm out?
To be fair, we can't see the business end.
I swing below the mount for the hood strut. I find there's enough for 1-2 clicks. It takes a little patience, but it works.
You can unplug those for the time being
That's what I did most recently. But yeah, you can disconnect those plugs around the booster and MC too if you prefer.
@XR7-4.6 thank for the tip! Because pulling the engine YIKES haha, maybe if I ever 4v swap it.
A little soylent green and that engine bay will clean right up....Pulled the engine today, what a filthy task with 27 year old gaskets GROSSSSS

I moved to purple power at some point, but I'm going to try the green again.
TbirdBrain used to do it. Unfortunately he passed away some time ago. I have a set of his manifolds. But they are installed on my sons "shitbird" so I can't take pictures.I feel like I've heard about a shop that used to port these.

That gauge on the steering column is pretty sick. Where’d ya get it?Dropped the engine in yesterday and fired her up with the new ported PI heads and she sounds spicy
Today took some time but I installed the vortech head unit, clocked it and pretty much ran ran all the intake tubes all the way up to the throttle body. My pops wired up the new slot maf aswell.
Pretty much the only things left are
Run the PCV hoses
Secure the coil packs
Secure the intercooler
Wire up the gauges
Aaaannnnnddddd tune it. Which is gonna be the hardest part. View attachment 11084
