    Haha nice.

    Man if I had time to make a little video for every fix I have done...
    Could write a video equivalent of a novel.
    I rebuild / upgrade Supra Differentials - PM me for more information.

    Yeah, filming is the easy part. It's the editing that I can never get to. I've probably got dozens of hours of footage I'll never edit to make a worthwhile video. I've got AC service footage, T-belt, Intake refurb, valve shim adjustment, etc... What has been really nice though, is that on multiple occasions I've gone back to review video to find where I put that damn bolt or gasket or small part.

    Anyways, UPDATE!


    You have to know where you are to know where you're going. The car had its BIC downpipe removed for emissions recently and I kept it in its stock form until I could dyno it. Results were about what I expected, but there were a few surprises.

    Power: 179 whp @ 5411 rpm
    Torque: 207 ft-lbs @ 3400 rpm
    AFRs: 13:1 @ 3500 rpm
    10.0:1 @ 5411 rpm
    Boost: 6 psi falling to 4.5 psi

    The boost dropoff wasn't something I expected. I can feel the car doesn't have the top end that my last mk3 had, but I've never stared at the boost gauge during a redline pull to actually see boost dropping so significantly. Simply adding an electronic boost controller might steady boost at the manifold. The CT26 should be more than capable - even in stock form - to hold boost pressures up to 12+psi up to redline.

    AFRs were surprisingly lean near peak boost, but I'm skeptical of the accuracy of the clip-on-muffler AFR sensor used during the runs. I'll get a real wideband plumbed in at some point - hopefully before the next dyno.

    Next Steps:

    • Exhaust is already installed. 3in turbo back. BIC divorced, recirc'd downpipe; 3" hi-flow, metallic cat; Tanabe Hyper Medallion Touring - Video coming up next
    • Engine Build?
    • Standalone?
    • Interior Touch-up?
    • Body Work/Paint?


    I feel like the engine build is probably the most universally useful. I've got some leaks still and the current engine is a big question mark as I haven't had it open. I've got some parts on hand, but will need more, certainly. My current Probe pistons I'm debating selling to fund some higher CP pistons to boost my mid-range torque. I want to have the most linear power band possible and I think bumping pistons to 9:1 or higher would go along ways in doing that. I've got a lift in the garage now so doing a winter build seems almost like a requirement, haha.

    What do you guys think? What's the next step towards a 500 whp build?!

    Nice build thread! I like the videos too. I'd say the next step in your quest for 500hp would be to build the engine with forged internals, oiling etc. you need a solid foundation to build from and have confidence in. Best of luck!

    Hey I love that volt meter and was wondering if you had some to sale? Also where is it reading from under dash harness? Plug in or spliced?

    I think I have all the parts in stock, but I can verify if lead time is important to you.

    You can wire it up any way you like, but I provide some quick'n'easy T-taps to clamp onto the cigarette lighter power wires. If it's just a reference that method has worked well for me. If you're more concerned about accuracy you could route it however you like with a more secure crimp connection.

    Thanks just put a order in and no lead time is not important as long as its reasonable.

    Sweet, thanks! I'll get that together and sent out to you. I'll have to check on my green display inventory.
