Hope this helpes…
With these injectors and adjustable fuel pressure regulator I had to lower fuel pressure to keep from not dropping AFRs into low 10’s when wot or open loop. In 91-93 pump gas
Just an FYI.
I also hit 95% duty cycle on e85 at max boost 4800 rpm 3 rd gear.
So limit there…
Raise fuel pressure could he had if needed. It’s down in 20’s now. I have to unplug vaccume a see what base no vacuume is I have a gauge on my regulator.

Elate sent me this when we were doing a supercharger on my truck as a reference for flow rates needed for injectors.
I have a front mounted intake on my 4.7 and that creates issues getting my huge TB to align to my air box lid with MAF sensor. It required special adapter Elate had to fab and send me and new throttle cable to be made. It took some doing but happy over all.
It’s all worked out eventually and found a hose to connect my tb to air filter housing. This all took some doing and patience. Elate never let me down and stuck it throught to the end.
I wondered if he would, and he did. So why he telling your rear intake inlet I bet.
Air filter positioning on USA spec trucks creates the issues with larger throttle bodies like ours.
Take care

Also Sept belt ! Get ready for an issue there too. The belt sent is to long , snap the throttle and tensioner pulls up slack to run the tensioner pulley belt to the belt across it. I had to work in a shorter belt. Also the belt tracking was off with the supplied flat pulley. I had to file the mount to get the belt to track straight.
Hasn’t thrown a belt since. It did jump a groove before I fixed the tracking. I now have the smaller pulley and again, shorter belt required.
Depending on your setup if you want to come see in person mine, let me know.
Show you the mods required and what I did.

Following. I've seen some of the supercharger stuff posted but I think most are on VVTI 100s. I believe yours is the first I've come across that's a 98-02 4.7/4 speed.
Are you currently using the sequoia ECU? I wonder how different the 99 to 2000 ECUs are. I know I got ATRAC/VSC added

Thanks @obe12 much appreciated. I am stockpiling parts for when the time is right. For now, I still need to finish installing the rear Dissent bumper and then shifting to 40gal LRA fuel tank. HID kit I purchased 2 years ago still in the box that I need to do something with soon. And now ordering up a sound system. Luckily this will keep me busy enough until tariffs clear up, hopefully.
I assumed that the rear entry similar to the Bullet kit is easier to adapt to our throttle body than a front entry for the charger. I like the look of the front entry more but will settle if it’s a bit more plug n play. I’ve heard nothing but good things from Elate so excited to get this going in the near future.

I have yet to get the sequoia ECU going. Why, have to wire a relay in place of my Fuel Pump ECU in back that varies voltage 1-2-3 , low , med , hi based on engine load commanded by the 99 LC ECU.
I having removed my drawers in the back yet. They block the removal of the side panel to gain access to the Fuel Pump ECU.
I have guldwings ready to install in my 100 like my 80 to gain access to the rear from the rear side windows.
When I remove the drawers to do the guldwings I was going to do the Mod to Fuel Pump ECU to convert to relay off on controlled by the Sequoia ECU.

Here is the completed throttle body installation after adapter Elate sent me to help align my TB to air box.
I'm not sure who you were looking at for the valve body but Cruisers and Company here in CO sells the valvebodies and they might have some in US stock.I would be ok with 25% but after discussion with Elate some of the items in the kit get hit with 50% while others are 25%. Additionally, there’s the potential for tariff stacking which creates a lot of unknowns in the final price.
I purchased all the supporting mods based on @obe12 thread here and @J1000 except for trans valve body because tariffs.
Plan is to run E85, 12 hole injectors, adjustable fuel regulator, piggyback ECU. Mine is a 99 with a larger throttle body so Elate said I’ll need a rear entry charger HTV1900 unlike the front entry here.
Again thanks for charting the unknown. Hopefully I can be part of the SC club soon@obe12 looks like you’re 25 miles north of me let me know if you’re tired of the charger and want to get rid of it lol.
Yes it's true that E85 causes a lot more condensation. Here in CO it's pretty dry but I could imagine where it's humid it could be crazy. I empty my catch can every 2000 miles or so.
Check out the local E85 price.
lol, I was looking too. It’s unclear what the tariff is…10% or still 25 for auto parts. Let us know if you find out.
That is what the price has been for the last few months since I've been looking into this. That cost doesn't include customs fees unless they have a US distributor who will pay the tariff in the beginning.
Add to cart and roll the dice?

The 25% tariffs for auto parts are under Section 232 of the Trade Expansion Act of 1962, and not under the “reciprocal” tariffs from the current administration.
It’s a complicated system based on HSS codes for each part of the kit. Potential for some items to be classified as auto parts with 25% tariffs and others under general reciprocal tariffs or under steel/aluminum parts under Section 232 that get hit with 50% tariffs.
From discussion with Elate some months ago, there is the potential for tariff stacking as well.
The price you see on the website is solely for the kit. The tariff/import fee will be calculated and billed directly to you by the importer/broker. In my experience, this has been paid directly to the courier before the package can be released.
Getting us back on track here and from discussion with Elate, anyone with an earlier model 100 series with the larger cable driven TB, they’ll need to use the Harrop HVT1900 which is a rear entry charger.

Starting to agree completely on the 5.7 vs 4.7. The head gasket issues they are having over there give me major pause to buy a 200 vs. just buying this kit after I'd already modded my 100 to do everything I could ever need. Just needs more power in the mountains and this seems to solve that with a reliable option. I've reached out to Elate to get the process started.
I really want to grab an elate as well but the tariffs have that on hold for now. Please let us know how the process goes and how much the tariffs add, if you don't mind sharing. Congrats on getting the process going!
Will do, will be interesting to see what the final number shakes out to be. Either way, much cheaper than a 200 series and rolling the dice on an engine problem. Shame we can't even look at GX550's or LX600s for an "upgrade". Zero chance I'm dancing with that TTV6 right now. The engineer in me screams "design flaw", as the machining debris excuse doensn't make much sense to me anymore.
Slew of dumb questions...
The upgraded fuel pump, does that have to be installed in the gas tank? Bc if I'm dropping the gas tank, I might as well replace it with LRA tank while it's out.
Are new fuel injectors necessary? Or would cleaning stock ones suffice?
Where does one learn about lambda and other variables that matter after doing this mod?
Which gauges are necessary to install and keep an eye on after this mod?
@J1000 @obe12
Thank you

So I've been in contact with them on my 2002 with cable TB and he's telling me I should go with the front entry version. I sent him pics of my engine bay. Wish this was a little more straightforward.
I have the same TB on my 01, Travis said (this was a while back) the rear entry was a better choice for the monster TB. I ended up buying flanges and will make a TB adapter for the front entry SC. Fortunately I ordered before all of the tariff BS started - curious to see what that turns out to be as well.
This is what he told me after I sent pics of my engine bay yesterday.
"The FDFI units were never an option as there wasn’t a solution for fitting the larger throttle bodies to a front intake charger. That’s changed now as a new 90 degree throttle body adapter is available to use.
Some LC100 have an airbox really close to the engine in an awkward spot so in that case using the HTV would make more sense as the TB comes off the back of the charger and plumbing to the airbox can be abit easier.
In your case the airbox is in a good position where the FDFi with 90 degree intake would work quite well ."
Hmm sounds like he's saying with this new adapter, we should be good to go with front mount now. See pics he sent me.
