Hello. First off. I have used the search button. I've read every post about the exhaust and intake manifolds for the 1st gen transverse. Encountered some conflicting information. I wanted to to focus main on well.... the restrictions on this platform TO ME seem to be :
1: OEM Intake manifold throttle body diameter being small as shit
2: The 1.75" inlet diameter on the turbos.
3. Super sub par flowing exhaust manifolds

I'm not going to replace my turbos yet so wil focus on my ... following down the rabbit hole on numbers 1 and 3.


1. Intake manifold issues/opportunities:

1a- high jack intake coolant tube for chilled secondary?
I have actually bought a second intake manifold to see if I can dr up something useful.
1.a- I notice there is a HUGE ass coolant tube running in-between the upper and lower manifolds. This connects to thermostat housing
I am currently building my own diy- expansion valve/evaporator T-in to the AC lines style chiller for use with the intercooler (need to have a water to air BUT).
I'm wondering how hard it would be to relocate that thermostat housing, and high jack the coolants paths in this intake manifold to use a secondary coolant system that is chilled. Honestly it doesn't sound that bad...but thats assuming there aren't other coolant paths that lead to the block or else where I'm overlooking.

1b. Tiny TB size booooo
I've spent some time looking to see if there are ANY compatible intake manifolds with a larger TB size, larger plenum....anything really. It SEEM like the Explore ST may have a year or so compatible with out manifold, but their upper is plastic- so I don't know how much boost could reliably be ran?

I ALSO read some post where someone mentioned a guy that somehow pieced together two separate TB mounts/paths to the manifold. I cannot find any information to this. Not sure how this would work with the MAP . MAF system ? I could jerry rig a controller to say, take the inputs from two separate MAFS and then sum and emulate a single one?


1c. I think I've seen two instances of people making their own manifolds.
1c.i- I believe Paradigm Racing ? used to use 3.5 ebs and they had some in house manifold
1c.ii - I've read a blog where some dude basically used a laser sintering approach to print his own manifold.I'm an engineer in R&D and have had a friend who's had some parts made and he was suprised at their strength.
You can actually now buy filament that is metal particulate encased in a kind of binder polymer. You print the object at home, and then send it to a company who basically throws it in a kiln. This process burns off the polymer and effectively "cure the metal part". I'd be interested to see if anyone has done would do this. please open source your models?


3. Exhaust Manifold
1 Headers:
So I have a 2014 Lincoln MKS. From what I understand, I have the decent exhaust manifolds for the platform
ALLLL the obx stuff is cheap af on walmart's website. I wonder if they're going under?I know they used to have downpipes for our platform and have read they kinda sucked but check this out:
3.a

Looking at the pattern on the gasket, it looks like it would mate with ours pretty well with a little porting.... it just has a different style ****** at the turbo, and would need some kind of an adapter....or am I overlooking something?

3.b. I've seen some decent looking catted headers on amazon. Does anyone actually run their at before the turbo? Back pressure wise this is a great idea. Particulate matter getting thrown into the turbo...makes it sound dumb though.?

I'm at work, and I need to do my damn job. I may come back and edit this later.
But seriously - those headers..... those wont fit?! Does ANYONE know of another intake manifold that isn't restricted by the tiny ass throttle body mount size?

You are way off from start to end.

First the exhaust manifolds. They are for a longitudinal motor with a completely different turbo. If you cut the pipes off, you MIGHT be able to get the flanges to bolt on. Nothing else on them is useful in any way. Search the forum, there are a couple people working on custom manifolds.

Next, the coolant pipe. It is necessary and cannot be eliminated. Again, multiple discussions on this. There are some options for wrapping or coating but not eliminating.

Next the Throttle Body, multiple posts describing how to use a Mustang 70mm. It also sounds like you are talking about the Manifold and not the Throttle Body. PARAGON Autosports makes an intake for the longitudinal EcoBoost (discussed in threads on here). It is not compatible. Manifold modifications are custom one off pieces and involve splitting, modifying and welding back together.

As far as HIJACKing the A/C system for chilled paths, a much more feasible method is CO2 which is also discussed in threads on here.

Lastly, cats before turbos. No people do not run them before the turbo. Back pressure pre turbo is not a great idea. You want fast easy exit for your exhaust so that it can A) scavenge the cylinder and B) spool the turbo.

"You're off....." I like how you started that off so constructively. You know, this isn't a contest, this is supposed to be a place for people to discuss and understand. I'll adjust my overzealousness though, I don't wish to evoke any further righteous cynicism.

I wanted to move that intake coolant tube to the chiller side instead of regular engine coolant but it sounds like that's not worth the hassle.
You're right, Paragon. Welding and cutting aren't that hard. It seems I have no choice.

I was speaking to both. I honestly would like to run a separate manifold on each bank with it's own TB. The greatest hinderance to airflow in the intake manifold is the mounting inlet face for the throttle body. Even with a 75mm.... TB, I mean you guys know how restriction to airflow works.

As to the exhaust manifolds, I have not read those threads. I will look more. I see what you're getting at, I looked at the pattern on gaskets and was filled with hope.

To every human being that HASN'T gone down this rabithole...
Interchiller

these are not same kit or mf, just 2 different examples if consumer devices currently in production.
Fi inter
magical almost exits. Magic = Latent Heat of Evaporation (c02 or refrigerant.(With regards to the c02 chilling) Even if you roll with a tank, c02 comes in a finite supply. The vehicle already has a condenser running. It feasible and effective to "T" in an expansion valve and evap core (usually braised plate hx). Check them out, the intake charge temps that FI Interchiller gets with the Stage 2 kit are ridiculous. Several consumer level kits exits, and those things are freekin magical. I'm just not going to drop 1500.

I asked about the cats pre turbo, because one peek on ebay:
and i keep seeing what look like.... better exhaust manifolds that what I currently have....but that cat tho. Sounds a little wierd, it's why I asked.

I would agree that back pressure is bad AND cats pre turbo is not a good approach. At least with one big cat.

I agree with @Ta2dResqr assessment - however there are a couple of choices without getting a TB that might cause issues:


or

This will be in my signature shortly - thanks to @85castle for this find: https://www.gigsperformance.com/

Will have a 73mm TB this weekend.

I'm currently running a intake manifold with divorced coolant pipe. In fact it's modified to run normally aspirated 2010 to 2012 coolant routing.
Just no pictures of the latest version of this.

More info on this 73mm TB? Which one did you get? That site is temporarily down
I had no choice I went with gigs TB, tbh I WAS going to do Maxbore. Gigs ended up being a bit of an unfortunate wording issue. I have been meaning to get some logging, however went to San Fran and came home sick.

Follow the convo here from @Jordan_R and myself:

What is your goal? 0-60 of x.xx, 1/4 mile xx.xx, seat-of-the-pants feel? There are other, easier recipes to get you any of these. The most basic is exhaust, intercooler, and tune. Throw in E30 and you've got an 11 second car. Messing with TB, intake, and manifolds are the first places to go for NA engines but wouldn't be where I'd start with a stock boosted engine.

How's that TB working out for you?
Look with all honesty - I feel a better take off response - so when I would push hard to get the car up and running - I have been side tracked and haven't done a 1/4 mile run or created logs yet for Brad. My daily driver has a blow by issue, in it's infancy so I have been researching replacement rebuilds. I do promise to make some simulated runs and get the logs and will return with a factual assessment shortly.

My non fact based suspicion.... Not much difference over OEM.

Wrong platform to do R&D on. If it wasn't limited by transmission and being a completely ass backward AWD set up I would say wear it out. Do yourself a favor and get a f150 ecoboost if you want to mess with a 3.5. Your wallet and your sanity will thank me later.

I didn't know sanity was a requirement for this forum. Does this mean I have to leave? LOL

The SHO did drive me crazy in some regards. It was a great car when I stopped modifying it. So I decided to buy a big turbo Lexus, because I am glutton for punishment and clearly hate money.

I can say the same for the ealry SHO's too. A little tinkering and drive it. We didn't even have much improvement with tune vs turbo cars. It is a limited driveline with FWD based config

Bro if you can get the heat out of the engine bay and keep the car running cooler add in a sandwich plate oil cooler and pull the cooling of the oil from the cooling systems responsibility if you have a PP and free up the Transmission cooler by giving the ptu it's own cooler and cover that center valley heat pipe.


If i can get up to 40mph with the vents and all the effort to expand and segregate cooling responsibilities I do not have the heat soak problems that the average SHO does. All this to say you can arrive at a really good cooling solution without going too totally crazy.

I will say I’m surprised by the relatively low power numbers people reach after boosting a Yamaha. But, all things considered it’s in what, at least 1000 pound less car, FWD and a manual trans. 300’ish HP is plenty of fun.

My little Focus makes like 280 to the tire and it is a blast.
