so many videos of turbo charged IS350 and ISF on youtube. I emailed sts ad today they wrote me back saying they do have a universal single turbo kit for a
IS350 that on 5lbs will produce 125-150hp. Idk...
I've certainly never seen a properly working one.
What I have seen over the years is a number of vendors/makers promise they were making one, and then produce nothing for sale.
Every few months for a while there someone would come in here and announce they were gonna turbo their IS... after people explaining the issues with it they insisted oh, no, THEY knew what they were doing, and just watch!
Most were then never heard from again... a few would admit they looked into it and gave up... and one guy claimed he did it at low boost, and was going to switch to 10 psi soon, then when asked for evidence he made excuses for a month or two... and then claimed he blew the motor up and vanished.
Turbochargers.com as another example screwed over several owners, eventually producing one really crap IS-F that needed 2 other places to work on it later and AFAIK
never worked that well... plus one IS350 that was left in pieces and never actually turboed- then after blaming an employee for all the problems had the nerve to want to charge the 350 owner to put his car back together (again, unturboed)
There's a drift IS350 that lists as turbo on youtube, but the engine isn't the one that comes in the IS350, and just about nothing factory is left or working in the car.
There's a couple threads here and on CL about the STS thing, where they said they were thinking of making one for the car but never did.... they sell a "universal" kit which they will tell you fits on ANY car you ask about but again I know nobody who has used it, and it doesn't just bolt onto the car (hence it being universal)- you then need to find someone to fabricate all the custom intake and exhaust plumbing for you.
At which point it probably WOULD work at 5 psi... and you'd have spent a large chunk of money to add 40 whp to your car. (which is probably why nobody has bothered to actually do it)
Now supercharger kits exist.... though not in the US.
LMS made one for a while and then after selling like 4, ever, realized $6000 for 40whp was a bad deal.... AFAIK
they'll still sell you the mounting hardware and stuff if you ask nicely though.
Outside the US there's at least 4 I know of for the 2IS:
TOMs- which is close to 10k and requires a JDM ECU- 5.5 psi of boost.
Arma- which I've never seen anyone credible actually run, and it's made in china with somewhat weird info on their web pages
Some South African place I can't remember the name of that supposedly did a 250 kit- with results that never made any sense, and for about 2x the price of just getting an IS350 instead.
HKS- which makes a kit that fits JDM models- You can mod it to work on US models (HKS350 did and was running 7 psi last I knew) but this is about $7000 and then requires programming of an HKS F-Con, so with program and install closer to 10k new.... for significantly less gain than just going to an IS-F would give you.
