    So I’m using the CXRacing exhaust manifold and I was wondering if I could put B1S1 in the cylinder 1 pipe and B2S1 in cylinder 6 pipe. I’ve seen people do this but I’m curious how well it works out because I’d like to just weld a o2 bung in and call it at that using stock sensors. Trying to...

    With the maf plugged in, it starts up at about 1200 rpm’s and then immediately stalls out. When the maf is unplugged it idles and runs great in limp mode. Issue persists with a new sensor. And if I pull the maf out and blow air over it while starting it runs great then too. Looks like it would...

    Does anyone use the Link G4x panic wire PNP for the IS300? Looked through the forum a few times and couldn't find anything. I have been emailing with them regarding some questions because I am getting ready to cough up the money when I finish building my JZ. I was confused on how I run a...

    Does anyone run the PNP offered for the IS300, I'm looking into it and only have found a few threads on it not going into much detail. When running this do you keep the MAF and it just sits there as a placeholder while MAP and IAT take care of it? Along with the Auto transmission plugs, and...

    What’s the better option between the panic made Link G4X and the Ecumasters EMU? There’s other options like Haltech and aem infinity but other people have told me the other two listed above are plug n play

    I've been extensively researching everything related to turbocharging the 1st gen IS and I've put together a list of what I THINK will work well together. I'm basically just looking to find out whether or not these would all work well in harmony together. Also what ECU would you guys recommend...

    I have a 2001 IS300. The stock 2j is decent and just fine for anyone if they're searching for a competent daily. For me, the 200hp fed to an automatic isn't kicking it. For a lot of people, it doesn't either. The problem I'm finding is that dropping a turbo on it is expensive on its own...

    What’s up fellas I got a ‘03 is300 and like many I plan to turbo it in the near future, however I own a turbocharged car but I’ve never turboed an na car before so I’m trying to figure out the best route for tuning. Are there any good standalone ECUs out there for under $1k that I can plug in...

    Hi All, So me and a friend are in the middle of a NA-T turbo install using the CX racing turbo kit. We've run into a small roadblock though. My questions are below: 1. What's the best way to feed oil to the turbo? The kit came with a sandwich plate for the oilfilter, but I'm not a fan of...

    Hello all. I drive a 2004 is300 auto that is pretty much stock. The only modifications are a cold air intake and a performance radiator ( it came with the car when i got it). I thought the car accelerated fast but I guess I gotten used to it so my goal is the reach 350hp or at the least 300hp on...

    I don’t know much about car computers but I just put the cxracing turbo kit in my Lexus IS300 (2jz-ge) and now I need help tuning it. Can I just tow or drive it to a dyno tuning place and they tune it up and it’s all good or do I have to buy a new ecu, chip, piggyback or something. Sorry if it...

    My first post here, I just bought 2 is300’s ones an ‘05 the other an ‘03. I’m looking to throw a turbo on the ‘03 but I don’t want to see a rod put a hole in the oil pan. I’ve done my searching through forums and have learned a lot. But having specific examples of people in similar situations as...
