  1. MKIV (1993-1998)
    I’ve been looking into the g35-900 (power goals around 550WHP pump and 700WHP e85) and want a responsive setup so thought of getting .83 A/R but they only come single scroll. For twin scroll I would have to get a 1.06 A/R. Would the single .83 spool roughly the same as the twin 1.06? How would...
  2. MKIII Technical
    Hey guys! Just got back from a drive and after popping the hood I noticed that there was some oil that had dripped out of my intercooler piping and into my engine bay. It could just be a loose hose clamp, but now I'm worried that I'm getting a bunch of blowby from my rings being shot. My spark...
  3. MKIV (1993-1998)
    So i’m going to be swapping a 2jz gte into my sc400 (spare me i know i should’ve swapped it into the 300) and i’m planning on making a nice safe 500hp drift build out of it. My questions are what needs to be changed for 500hp in terms of fueling and turbo sizes i know the block and head itself...

    I was replacing my turbo, and I just got a donor turbo with the elbow still on it. I was able to remove the bolts but it’s still stuck on the turbo, I’ve used PH blaster, let us soak but still no luck, I heated it up too. I have no clue what’s holding it. It’s not even wiggling.
  5. MKIII Technical
    Hey guys my name is Jake. I have a 91 Supra with a 7mgte. I built the motor and I can't seem to keep coolant out of the crankcase after startup. It's fine when it's sitting but after I start the motor it will run for about 10-15 seconds and then hydro lock from the crankcase due to coolant...
  6. MKIII Technical
    Hey guys! I’m likely going to be doing a bit of a rebuild on my CT26, new bearings, thrust washer, etc. While i’m in there, would it be a good idea to swap out the compressor wheel for a lighter billet aluminum one, or stick with the stock? My 7M is stock currently and i’m not trying for...
  7. MKIII (1986.5-1992)
    Recently bought this 87 turbo. The intercooler to throttle body piping wasn’t hooked up and I can’t figure out what I need. Seems like I have a mix of aftermarket and stock piping so I need to figure out what goes where. Thanks
  8. Shops & Part Reviews
    Anyone have experience with the new Borg Warner S368 and S364 SX-R turbos yet? The new 68mm turbo seems like a nice competitor to the 6870 or EFR9280 while the 64mm is a competitor to the 6466. Both their compressor maps seem to flow lower than their horsepower ratings like how Garrett rates...
  9. MKIII Technical
    So the turbo spools up, I can hear it quiet well, but I don’t feel a push like i used to. The boost gauge also only reads around 2-3 lb/ft. There’s also an audible wooosh after I release the accelerator. Car is unmodified, and none of the hoses seem to be cracked or leaking.
  10. Canadian For Sale/Wanted - Parts, etc.

  11. MKIII Technical
    Hey all, I'm looking for good aftermarket replacements for the CT26 and not a rebuild/upgrade for my stock CT26. Driftmotion seems to have a good replacement. Does anyone have experience with Driftmotion's CT26? What's the performance difference between the Garrett 57 trim cast compressor wheel...

    Hello First sorry for my bad english. can i just remove 1jz stock turbo and add another one better https://store.kinugawaturbosystems.com/collections/supra-1jz-gte-vvti-2-5l-1/products/kinugawa-turbocharger-garret-60-1-upgraded-for-toyota-1jz-gte-chaser-cresta-jzx-100-ct15b-bolt-on like that...
  13. General Supra Forum
    As the title reads. I have a mk3 at the moment with the stock bypass valve or BOV.. whatever you wanna call it. Is there a way to put a block off plate in it? Or disconnect it all together lol. Getting a new turbo soon so I just wanna try it out. Thanks!
  14. MKIII (1986.5-1992)
    I'm wondering if I should buy one of these new but cheap-looking AFM sensors that supposedly work on my car. They say that they work on an 88' Turbo but they don't have the same KV sensor and instead have wires. I wonder if these are questionable at best or if anyone has ever used one...
  15. Builds & Projects
    Hello! I am new to forums, I tried looking around but couldn't find information on this. I recently purchased my first 2JZ, a GE Non-VVTI with 40k miles. I wanted to know what's the safe limit for my bottom end, keeping the GE rods and pistons, just adding a thicker head gasket to lower the...

  18. 1JZ/2JZ Swap
    I currently have a car with a 1jz vvti in it and so far its amazing. Only problem is I want to create more power. Right now i just have a big turbo some fuel injectors and an aftermarket cpu and can make around 500 on a safe tune with e85. Would it be better to push the 1jz to its max or should...
