1JZ GTE VVTi PULSAR TURBO UPGRADE DYNO SESSION

[@Korkoooo]

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

[@zimble]

Plenty of power! Sounds sick too

[@mikotyo93]

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

[@SDSGarage89]

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.

[@HugoHardinge]

Brett is a legend, he got me sorted as well years ago 🤝

[@Kespx]

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

[@SDSGarage89]

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.

[@Shadow-dj4ow]

why such low numbers? surely good for 500

[@ImKindaPanda]

omg been waiting for this video for so long XD

[@hafcinema7342]

Nice! I’m planning on doing a 08 Maserati engine & transmission swap in my 88 drop should be a fun project!

[@SDSGarage89]

That’s wild! Good luck man

[@FastLaneLyfe]

Surprised it’s not snowing 🌨️ up there yet. 😂😂😂

[@1jzjavi]

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.

[@1jzjavi]

I also only spent 400 for the turbo and 120 for the adjustable wastegate acuator

[@cliftonthomas2725]

What kind of gear box in it and how did you fit that 1jz in can you show the fab?

[@Cafendless]

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?

[@SDSGarage89]

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]

@@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

[@SDSGarage89]

@@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.

[@marcopolo8249]

Any ideas what was restricting it from getting more hp? Any inputs from your tuner?

[@SDSGarage89]

Noodling a few things around. Sorta guessing at back housing size but not sure yet.

[@marcopolo8249]

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.

[@SDSGarage89]

@@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

[@playinstar182]

This turbo must give around 500, not 350

[@FastLaneLyfe]

So how many nm of torque?

[@SDSGarage89]

354 lbs/ft so nm…. Uh…. Some nm of terks 🤷🏻‍♂️

[@marcopolo8249]

Pump gas?

[@SDSGarage89]

94 pump yeah

[@downshift7596]

I made 310 whp on my ct15 😂

[@MostlyCensored]

Timing bro, timing.

[@SDSGarage89]

There was a few things at play here, but you nailed the timing issue. 🤝

[@MostlyCensored]

@@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.
