YAAAAAAAS!
I finally got everything up and running!
I will be starting my own thread whenever I get more time to get pixs and vids. Buuut, it took me a full day 24 hrs (4 hrs was nap time ahah). But I started the day I received all the piping Tuesday at 3, to Wednesday to 3.. Overall it was straight forward, my main problem was piping, I found out I had the start from front to back to fit everything in between eachother.
Overall, everything was a good experience, I've driven it for about 180+miles and I hit boost around 4-5k, it pulls harder and longer.
I have 1 problem tho, I installed the boost gauge (drilled a hole before the intake manifold) and I only read vacuum, my BOV goes off so I know I'm getting boost but the boost gauge stays at -22. Can anyone helo me out with this?
Would it be possible to install a turbo timer?
If anyone has any questions about install or anything I can give you some (not all) details. As of right now I don't think I want to start making any of these kits.

Inlet to the turbo is fine with aluminum; but the outlet (exhaust side) will need at least to alum-steel.
Are you thinking of a remote turbo setup? My thoughts are that with a customized aftermarket header and cleaver turbo placement, you can fit twins in before the midpipe...if you even want to do a full exhaust that is. I've confirmed you can feed the turbos from the low-pressure factory access port in the front near the oil filter canister. Return can simply be a tap and drill job in the oil pan.

Hey guys I know it's been a while since I got back on the CL forums. 6 cars later and I am back to owning a lexus again.
In all honesty this was a fun project but I wouldn't go through the hassle again. After the Is250 I picked up a couple of OEM boosted cars and they're just so much more fun to drive than this is250 that I built a few years back. I'm curious to see if anyone else has successfully completed a twin turbo kit after I did mine
By the way... I picked up an 04 is300 and I've been eyeing a trubo kit for it so we'll see how this goes
