At 20 psi with that turbo you should be making 400-420whp. Something doesn't add up, either dyno reads extremely low (low % chance) or your tuner isn't great. Most likely you need a different tuner
Actually surprised it only made low 300s… up until last year I had this exact set up on my Chaser and made 580whp. You should definitely be able to get more out of it. Your numbers can be done with stock turbo
Yeah I think there are some compounding factors here. 1 being the Dyno dynamics unit this was tuned on reads very low. Hind site being what it is I don’t think we took it as far as we should have boost wise, plus I was starting to have a fuel pressure drop at the very top of the RPM range when I looked back at the logs.
Yeah it has left me with a few questions. Dyno dynamics Dyno’s read very low so that may be a factor. It still rips which is great but a bit disappointing for from a numbers perspective.
Thanks man! Glad you like it. So my ego and wanting 400 is less than pleased, but the hour I drove this thing it was a blast. Taking it drifting soon to see how it changed it on track, new rear gear later this summer and we’ll see. By pure numbers it sucks but driving it is a blast so can’t be too upset.
@@234567king that’s definitely on the list of potential solutions for more jam. Going to have a good friend and excellent tuner pick through ECU calibration and tune to see can be optimized with the current set up.
@@SDSGarage89 I’m an old 7m mk3 guy, it always amazed me the torque the 1j makes when tuned properly. I’m not a pro, but the rod ratio has to be the culprit. I’m planning a 1j build right now and already predicted a lot of tuners will default to timing max best for the longer stroke of the 2j so I was listening for the snappiness of an advanced timing and it sounded like that was what was missing.

Plenty of power! Sounds sick too

Brett is a legend, he got me sorted as well years ago 🤝
Thats crazy id of thought youd be well over the 400s with that setup, the 1j in my supra made 346bhp on stock turbo ct15b

why such low numbers? surely good for 500
omg been waiting for this video for so long XD
Loving the series man, all your parts I’ll put on my 1jz Toyota chaser.
Will you be happy with the current 330+ hp or make it go to 400+ mark?

@@SDSGarage89the thing is all the hard work is done, probably wouldn’t be too hard to get a bigger rear housing or go up to a 770 style turbo

Hi bro i have a 6+6 blade turbo 62/84 from aliexpress with a mambatek wastegate spring 25 psi hybrid ct15 making 500hp on e85 this is crazy.
I also only spent 400 for the turbo and 120 for the adjustable wastegate acuator
Nice! I’m planning on doing a 08 Maserati engine & transmission swap in my 88 drop should be a fun project!
That’s wild! Good luck man
What kind of gear box in it and how did you fit that 1jz in can you show the fab?
Surprised it’s not snowing 🌨️ up there yet. 😂😂😂
Any ideas what was restricting it from getting more hp? Any inputs from your tuner?
Noodling a few things around. Sorta guessing at back housing size but not sure yet.
Thanks for the update. If you find out let us know. I was thinking of getting same turbo with similar set up but with 260 kelford cams.
@@marcopolo8249 off the hop a larger AR, like a .82 would help. This thing is fully lit at 4,000 RPM which is nice and responsive for drifting
So how many nm of torque?
354 lbs/ft so nm…. Uh…. Some nm of terks 🤷🏻♂️
Pump gas?
94 pump yeah
This turbo must give around 500, not 350
I made 310 whp on my ct15 😂
Timing bro, timing.
There was a few things at play here, but you nailed the timing issue. 🤝
