you can use it if you get all the parts plus in addition you need unichip for your 98 ECM. That along with cost you $1,500.00. In reality TRD SC only 6PSI max boost in the end people claiming that it is killing engine block that why Toyota discontinued.
That's not the case at all. And the Unichip is about half your quote.
OP. You should be fine. Look for a big thread, someone else used a different model SC on their LX, worked out fine. Just be aware that parts are unobtanium, so if something's missing you'd have to fab.

it has 82k on the SC. is it time for a rebuild? they want 3k, but i'm thinking that's 2x what it's worth with the mileage and added costs for the unichip. I need more power in the mountains and even though the headers are appealing, they don't seem worth the $700+labor for minor gains. Turbos are $10k and a newer 200 series is at least $40k.
I have TRD SC one on my LC100 2001 and LX450 too I installed them both, so I am speaking from an experience. it is not worth a money and time spend. like I said 6 PSI boost max at 2,000 feet elevation above the sea level, so you will not gaining much HP or torque - I am telling you waist of money. I know I can get leg and the arm for it by selling it , because some people are stupid, but I am just being truthful - do not do it.
Unichip is about $800, not $1,500. Toyota discontinued the 4.7L SC because of issues with the cast connecting rods used in the Tundra and Sequoia motors, no issue with the forged rods in the LC.
I don't know if you were expecting sports car performance when you installed the SC, that's not the case. If you were, I can see how you think it's a big let down for the money. I had one on my 80 and have driven a 100 series with one. The HP gain is noticeable. It won't blow you or the Ferrari next to you away, but you can tell.

Regarding the Unichip, what is needed in addition to this?
’01-’02 Land Cruiser 4.7L TRD SC | Unichip Wholesale
... this looks good and they do much cheaper these days
my is old I got 10 years back paid around $1,600 Toyota dealer was messing with the program for 3 days to get it working like I said cost me leg and the arm with not much horsepower.
I was expecting some significant power as promised on the "spec" +100HP +100LbTq , well BS+BS+BS=BS3 let me tell ya why.
so 245HP +100HP =345HP and that a lot HP, I have my new LC200 2009 that 380HP I can live in the dust low of sports cars.

i have a '71 SB stroked 'Cuda, so i got my HP fix. I love the LC and had a Taco w/SC. I just need some more TQ to help me push throw the mountain passes. Will the Doug's headers get me there? I'm not looking for neck snapping power, just a bit more grunt.
Honestly, sounds like you had unrealistic expectations. A Land Cruiser's 4.7 is 230 HP (unless you had a newer one with VVT). Everywhere I'm reading about the TRD supercharger (feel free to cite your own sources correcting me) is saying to expect 50-60 HP. That puts it firmly in the 280-300 HP range, which is significantly less than the 380 you're getting in your '09. Having owned a full size pickup that weighs about the same as a 100 and came with 285 HP, it had plenty of power to get moving, but certainly wan't anything remotely close to a sports car. I was quite happy with it and wish my LX had that kind of power available.
These days, I only want adequate performance from my daily drivers. Riding a ZX14 will put "speed" and "acceleration" into real perspective...
strate from the book word to word:
"Now you'll enjoy power gains of over 100 HP (stock is 240 HP @ 5200 RPM), and 100 lb./ft. torque (stock is 315 lb./ft. @ 5200 RPM)."
if you really want to do it here is info for U-CHIP

there , in Russian (too bad) but what we had to put up with. go for it you Americans risher can afford it.

I'll have to take your word for it since a google search for those exact words only brings up the supercharger for the 4.5L - not the 4.7L...
4.5 is 212 HP not 240 but anyway even better 300HP is powerful too - I do not feel it 300HP
Leg and arm.... That's ridiculous
I'm aware...just saying what those exact words show in a search....
so many years have passed I found this conversation to know if you got TRD for you 100 and if so how the feels?
Is your gearing on spec? That might help a bit more
