Turbo Talk

[6.7 Coal Train]

I've decided I'm going to slowly accumulate parts for my 2nd gen swap over the next year and install everything in 2022 - so way out there.

I'll get an intake horn, grid heater delete, steed speed manifold, piping kit, coolant tank (maybe), studs, analog gauges, FASS etc. - a piece at a time here or there so I don't have a $6000 bill all at once in the end.

Built trans. to come when the stock one goes, but trying to avoid that $$ for a while even if I have to keep it turned down.

I wanted to get some input on the finer details of turbos.

This is my daily driver. I won't tow over ~9,000 lbs max (23 ft wakeboard boat loaded). Shooting for around 700hp, I'd like to keep it on stock fuel for the time being, if possible, and I don't want to get into the motor either.

700hp is for no other reason than my own personally enjoyment. If I can't get there immediately without fuel, oh well, at least it's possible down the road with this setup.

Think I'm pretty set on an S467.7 - open to other suggestions of course. Have considered a S464.5 but I don't see them offered much.

It's the other aspects I'm in the dark on.

I think I'm fairly set on either the WCFab S400 kit or the Evil Fab Labs kit.

I may or may not get the turbo directly from either one of them, but their turbo options got me wondering what to get.

Both have a S467.7/83/.90 (WCFab: FMW, EvilFab: Billet). FMW or Billet better? This size seems very common.

Now, I hear about .90 housing overspeeding quite a bit as I poke around the internet. Although, I am in Wisconsin, not at altitude so maybe not an issue? .90 just simply requires proper tuning in general?

So that drives me to the Evil Fab side where they have an option of a Billet S467.7/87/1.0 - is this turbo still daily drive-able? Is it even necessary over the 83/.90 for my purposes?

Sorry for the book here, but I can't find a good turbo thread anywhere. - Feel free to dump any other turbo info into this thread if it's helpful.

Fuel will be a whole other conversation down the road.

I have everything but the turbo myself.

I've been told that you want bigger injectors to light the 467.

I've also heard of guys running them with stockers, so I really don't know.

Exactly.

This is the kind of stuff I want to get to the bottom of before committing to a 467.

S464 won’t get you to 700hp.

Be honest with yourself do really want to spend the money for 700hp? Its gonna cost you 15-20k to do it right and keep it reliable by the time you get transmission and other supporting mods.

S465 is good for towing on stock fuel but honestly so is the stock VGT turbo and you won’t gain much going from stock VGT to the s465.

S467.7 is the way to go but you are gonna want extra fuel. You’re gonna see a lot of people say with out with out fuel it spools just fine. But they are full of it or don’t know any better

Remember you limit out on stock fuel around 500hp ish stock VGT can get you that or really close to that just need support mods and trans mods to make it reliable. S465 is good to around 550 depending on who you ask not worth the extra 50hp for the money if you ask me.

I ran the s465 for about 6 months I personally hated it. Now I run s467.7 with 200 horse injectors and dual CP3 made 740 on the dyno it has more In it but not going further until I get rods.

That's good to know.

Maybe Ray was staying on the safe side of power for reliability/drive-ability/fuel restrictions?

Everyone I talked to including Ray said the s465 runs out of air long before fuel becomes an issue.

I originally saw people claiming bigger numbers with the s465 so I went with it. Quickly found out it’s limitations in the 6.7 application.
