Hello everyone,

I am planning on doing the 80mm TB upgrade on my IS and I'm planning on using the TB off a 98-01 GS400 (pn: 22030-50110) ... if anyone has one they'd like to get rid off let me know ...

I'd like to get rid of the DBW system and I know that there's a kit for the stock IS TB that eliminates the DBW (http://global.rakuten.com/en/store/p.../item/kit-005/)

Do any of you know if there's a similar kit for the Gs400? Or is there a similar solution?

a friend of mine claims that this kit

fits any vvti 1uz-fe

he came to the conclusion by comparing internals of throttle body assemblies from jzs171 and ucf20.

Thanks!!

I just ordered the same kit and I wanted to see if anyone had done the same.

here's his writeup on the topic

at least you will see side by side comparison of the throttle assemblies' parts
google translate may help with the rest

GeorgeNVA: thank you so much!! This is great!

I'll post a write up once I get home and have time to work on the throttle kit

Update:

I found a Premium Japan Throttle Kit on eBay for $250 and after tinkering with it I was able to retrofit it to the GS400 throttle body.

Very cool indeed. How do you like it compared to stock?
