- After experiencing some ignition issues with the LQ9 coils, I decided to overhaul the ignition system and upgrade (yet again) to the IGN-1A coils. Hopefully I'll be able to get the car on the dyno soon and with any luck crank it up to break that 700 WHP mark!

Thanks for videos like these, very valuable info for us building our 300's. Keep up the great work!
Yesss another build video! Its been a few months glad to see another!
I love this build!! Between you and garage project motorsports ive pretty much got all the info i need. I have my build in progress now and just got my driveshaft today from the driveshaft shop..... customs have emptied my pockets though!
Hey Robert, that's exciting! I can't imagine it's cheap to get parts across the border but I admire your enthusiasm to get the build under way. I'm certainly no expert but glad you enjoy my videos! Good luck on the build and thanks again for coming back!
She's super clean I love the setup
Thank you!
This is quite possibly the most bueatiful 2JZ I have ever seen.
Thank you!
Glad you made the switch. Car looks great too! Those coils are badass i love mine.
Thanks man! Can't wait to get it back on the dyno and hopefully crank it up! It's not going to be a 900+ WHP beast like yours, but it should be enough for a good time! =)
XtremeCoupe haha hell yea man you should make 700whp no problem
That's the plan!!
Goddamn that engine bay looks so clean and well put together it's like an OCD person's wet dream! 😍
Thanks!
Keep up the good content 👍🏻
Beautiful Clean Build on this is300 Brother!🏁🏁🏁👏👍👌
Beautiful engine bay with the exception of where you mounted the fuel pressure regulator lol
Thanks! To each their own!
Nice ignition upgrade dude, can't wait to see how it does on the dyno! What do you suppose the limit is on the stock ignition system? I'm at about 500whp at 22psi and all is well so far. Looking to turn it up a little with e85 and hoping my ignition (among other things) will be good.
Hey man! I was running the factory IS300 ignition system at 28 PSI on ethanol and didn't have any issues at all (running Denso Iridium IK27 plugs gapped at .020"). I'm still impressed with the capabilities of the factory ignition system, I just wanted to upgrade to something that I knew would be enough for anything I want to throw at it in the future.
XtremeCoupe Cool that's good to know. I'm running those cheap ngk copper plugs but might upgrade to iridiums during tuning. Thanks dude and good luck to ya.
Thanks man! Good luck to you as well!
One more question that you’ve most likely answered 100 times. Sorry in advance. Who did you use to build your wire harness.
No worries! The harness was built by Tweak'd Performance.
You find it necessary to run x2 450 pumps at the 6-700whp mark?
Wish I knew how to do that to my is300
Tremendous
You have a badass IS300 i wish to make my Is as cool as yours (im 13 and i have an is300)
Paint the vvti cam gear! Bought not built?
Do you have any footage on the recirculating catch can build. I'd like to see how that all went together! Awesome build!
Unfortunately I didn't get much as far as pictures/video of the catch tank fabrication. I should have done a time-lapse build on it!
I hear your frustration bro. Keep up the great work. What's your ig page?
Thanks! It's @two.jay
Do you make and sell the catch can?
I did make this one, but I don't play to make or sell any more of them. Sorry!
two jay ok. Thanks. Looks good man.
What kind of intake manifold is that?
It's one I built myself using the stock lower intake manifold section and parts from Ross Machine Racing (RMR).
@@twojay It looks awesome and I love how it comes straight forward like a GTE manifold instead of to the side like a lot of these aftermarket ones.
@@r.a.w.performance6602 For sure.
two jay, could you share any key details or resources that allowed you to successfully remove/relocate the OEM ecu box?
I had a full custom engine harness built by Tweak'd Performance that has the "patch" harness essentially built into the harness itself. The factory ECM is mounted next to the AEM V2 near the firewall on the passenger side (under carpet/behind dash). Before that, I built a huge extension harness and had the ECM mounted underneath the driver seat. I believe Figs sells ECM extension harnesses now for people that are looking to relocate the factory ECM.
@@twojay Thanks! Forgive my ignorance, because I haven't yet studied the wiring diagrams, but what about the wiring inside the OEM ecu box that doesn't go to the ecu itself?
I'm in planning phase, but the Link G4+ Xtreme has the canbus stuff figured out so the OEM ECU can be eliminated. I think I pointed it out in another one of your videos. It is currently offered as a kit, with patch harness, that puts the new ecu into the OEM box. Seems like a great solution, except it loses its plug and play goodness factor when you want a forward-facing manifold with DBW throttle (to keep cruise), and to ditch the OEM coil ignitors in favor of the IGN1A coils...
@@GroovesAndLands Yeah that Link ECU looked like a really cool option, but there are definitely some configurations where it's not quite as ideal as it seems. If you planned to stick with the stock intake manifold (factory ECM location) then it would be very clean and simple solution. Once you start trying to fit stuff where it wasn't intended, some level of rewiring/relocation is almost inevitable.
With my current setup, part of the custom harness still runs to near the factory ECM location because like you mentioned there are a few connections for the body harness up there as well. I basically run that portion of the harness through the engine bay and down through one of the holes behind the driver side headlight, so those connections are basically hidden behind the front bumper. The one drawback to this is that water could easily get to these connections if the car was ever driven in the rain, but that is non-issue for me because that will never happen. Hopefully that all makes sense.
At what point did you abandon the stock coils before going to the LQ9's? I'm running 24psi on the stock coils and havn't had any issues to speak of.
The LQ9 coils did not work well for me, that's why I went to the IGN-1A coils (as seen in the video). I was not experiencing any ignition issues with the factory ignition system, but wanted to upgrade to something that I knew was not going to be a bottleneck moving forward. I'm able to run more dwell and a larger plug gap with the IGN-1A coils which should mean a stronger, more efficient spark. That being said, I think there are plenty of builds that seem to have good luck with the factory ignition system.
@@twojay Cool, I was just wondering if you had run across a limiting factor with the facorty setup. Love the build and would like to communicate with you about a few other parameters on your setup. Is there a way to PM through TH-cam that you're aware of?
@@akarilotube No hard limitations other than having to limit the plug gap as boost/power increased. I think there's a way to message on YT but I'm not sure.
@@twojay Here's my setup, If you'd like to communicate, Brent at Side B Productions has my contact info. th-cam.com/video/0sTRSRC3o84/w-d-xo.html
I see you still have abs running next to the turbo, have you noticed any issue of soft brake pedal after boosting for a while?
Yeah I'm still running the factory ABS but I have not had any issues with a soft brake pedal or anything like that (yet).
Ls and lq9 coils will randomly fire if they get to hot.
can u make and sell the catch can?
More like XtremeSedan
Haha, no kidding! Might be time to change the channel name...
Hey man, what FFIM is that? i plan on going na-t soon
Hey Henry,
It's actually one that I built myself using the stock lower intake manifold section and components from Ross Machine Racing (plenum extrusion, throttle body, etc). I believe there are a few off-the-shelf options available out there for the GE.
XtremeCoupe damn bro that's impressive as Fuck!
What did you do with the abs?
It's still there under the intake pipe. I did have to move it slightly to provide clearance for the turbo/intake though.
Are you selling your LQ9 coils ?
Hey! Mojo actually gave me a refund (minus restocking fee) for the LQ9 coil kit. Sorry!
Yeah I am still on factory ignition and it's starting to break up here and there. I just got my GTE upper plenum to mount to the lower GE one so now it's time to do more upgrades lol.
Nice! Sounds like a fun build!
Yeah should be nice when it's finally done. Only paid 2000 for it with the turbo kit already on it and it's a clean title. Love your car btw super clean!!!
Awesome! Thank you!
I have soooo far to goooo! :-(
