    So, I was on my way home from food shopping. About 5 mins from the house the radio and ac would cut off then come back on. Then the battery light would come on. Car completely died when I got home. Automatically, I thought alternator. Replaced alternator, car wouldn’t start. Put my friends...

    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...

    I’m doing an R154 swap and I need the measurement from the output shaft to the stock auto lsd differential. Does anyone happen to know this measurement. I’d rather not wait until I have the trans in and have to wait on the driveshaft.

    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...

    Recently I picked up a junkyard GE for my IS300 that I'm going to be building for boost. I have torn most of it down and everything has looked amazing. I'm going to order my pistons in a week or so and get ready to hit the machine shop. I was getting ready to tear apart the head and I decided to...

    Picked up an 03’ is300 with 80k on engine and body. Car is mechanically sound (ish) however with my very enthusiastic driving it’s starting to struggle with retaining fluids. There’s oil coming from the pan seal, oil pump, and possible other places. Was curious if anyone has re sealed the GE...

    Looking to go for a new set of headers. Now from my research the port size on the head is about 1.4 inch. Are the stock headers the same diameter and if so should I get headers that have a inlet of 1.5 with a exit of 2 inch? Or should I go bigger. Any info would be good. I plan to keep the car...

    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 tried searching around forums but haven't quite found a solution. So I've replaced the throttle body from a used IS300, my car idles pretty low below 1k rpm idle even in drive as well and sometimes would have a rough start. It's currently in limp mode and I would have to press the gas...

    Literally paid 107$ to fill up on premium gas, what a pos lol. I’ve heard that running 87 octane isn’t that bad, car is already slow as hell so why not.

    Has anyone ran a Greddy RS catback exhaust with the 3rd cat deleted and stock headers? I want to quiet down from the straight pipe it has on it but no point of spending the $800cad on the full catback for it to still sound obnoxious.
