    Project Ookii Ao: Road to 500whp

    Part 4: Baselining My 90 has been sold, which has freed up funds for this project. I ended up getting $8k for the 90 gte swapped targa chassis. I left all the goodies on the car as the new buyer negotiated inclusion of everything, including the 5zigen wheels. In this installment, I go over...

    PWR - Radiator Caps - Type 1 in OEM Form?

    So my 91 car has a PWR radiator. It's a nice radiator, but the cap is not the same as what I find listed for a 91. The PWR radiator requires a "Type 1" cap. See this link and look at the picture: http://www.driftmotion.com/591-A001-p/dm1061.htm Is there an OEM pressure cap that is "Type 1"? I...

    How have a I missed this thread?!?! John, this is really, really neat. I hope you continue to post here. The audience is dwindling in numbers, but I think all the more interested as all the "fair-weather" lurkers drift to social media. josbeat, what lithium battery do you use?

    My Bad Experience With Rockauto

    I always had great experiences with Rock auto until I recently bought a starter that didn't work. For some reason it would not engage my flywheel. After installing it multiple times and re-installing my old one to verify nothing else was the problem enough time had passed that I was outside the...

    500hp build

    I'm currently doing a 500whp build. Here's my input based on my research thus far: 1. Bigger injectors. Out of 40 or so dyno figures posted on SMs HP list and a few other sources, only 3 hit 500+ whp on 550s. Give yourself some headroom and get something bigger. 2. Turbo. Out of my long list of...

    LED Retrofitting the MA70/JZA70 Supra

    Nice work on a lot of these items. Those Aventador style DRL and turn signals definitely have my eye... The cluster looks cool, as well. As someone who's done the isolated LED needles, I'm curious how you went about it. My approach is pretty well documented and publicly available via my sig...

    stock Oil Psi sender needed

    Does the ECU use the signal for anything more than a binary pressure/no pressure?

    Red Supra build 500~WHP

    Lex AFM and stock injectors will create a lean situation. You're tricking the ECU into thinking less air is coming in than reality.The Lex AFM MUST be paired with the 550's to get your fuel ratios even close to correct. That way you trick the ECU into thinking less air is coming in and into...

    stock Oil Psi sender needed

    I believe the ECU is just tied to a switch. It either sees pressure or it doesn't. The gauge sender is used just for the gauge in the cluster.

    Project Ookii Ao: Road to 500whp

    Hey, hey! good to see you checking in. Not much progress yet, unfortunately. Still haven't sold my other mk3 so the new 91 is just sitting for now. I've actually got the Raptor Racing catback and downpipe on my 90 GTE. It's awesome. If anything, it's a little too quiet at WOT and too loud at...

    3D Printed Supra Parts

    I like these ideas! I could totally make those! Possible, absolutely! However, space is VERY limited in that voltmeter. to avoid any modification to the bezel and make it 100% drop in, plug and play, I'm dealing with very thin walls and an extremely tight fit. I would likely have to get a...

    Oil smoke issue

    Sounds like valve stem seals, but that would be odd if you just replaced them. I'd do a compression test or a leak-down test if you have the equipment. I've never had noticeable smoke after the initial start up of a rebuild on a 7M. How old is the turbo?

    Bring back the Kaminari 3 piece spoiler???

    This shows some great shots of how the Kaminari is different than OEM. Is there any estimate on timing for this? Are we looking at a year out? 3 months?

    Project Ookii Ao: Road to 500whp

    Good info, thanks. The stainless issue is important. I also remember seeing the weight listed for the HKS Drager being more than I thought it would be. The Tanabe is 45 lbs in shipping according to Amazon, while the HKS is 60 in product weight.

    Project Ookii Ao: Road to 500whp

    No major cracks on the dash, but there is wear on the A-Pillar where it meets the dash. I haven't checked the top vent area where I know there can be cracks. I need to give the car a thorough detail and inventory all the little problems so I haven't inspected it too closely yet. Progress is...

    I keep going back in time! Finally found a mkiii--meet crimson tide

    Awesome pics and as I said before, a true inspiration. That exhaust looks great. It's one I'm considering for my new build and your car makes a great case for it.

    The Fruition of Obsession -- 310,000 mile makeover --

    Update: The journey for this car with me will be coming to an end soon! I'm switching over to a 91 Hardtop Turbo chassis and will be focusing my efforts on that car using the funds from the sale of the 90. I replaced the lower ball joints on both sides and both front wheel bearings. That...
