- In this update, I take the car over to the dyno to get everything dialed in. Everything goes relatively smooth aside from fighting some ignition issues throughout the course of the dyno session. I ended up having to stop around 21 PSI due to ignition problems and will have to re-evaluate the ignition system before attempting to turn it up any further. So far the LQ9 coil "upgrade" is a huge disappointment.

Looking good buddy. Hopefully you can get the ignition figured. 👍🏻
That's what I get for using GM parts! Haha.
XtremeCoupe yeah what the hell were you thinking?!?!? Lol
@@twojay How much lag did you gain with the 9180 turbo?
This video should put things into perspective about what's required for a build like this and the time involved.
Man, I love these videos! Gets me super excited to get my turbo is300 up and running again!
Hey Corey, thanks for watching and good luck with your build!
Man! I was pumped about this Dyno Day video till the LQ9 coils started their shenanigans.
I remember once asking in one of your videos about your ignition setup, when I found out it was the stock IS300 ones I was shocked. Now I am even more after knowing theyre more capable than the LQ9 setup.
What we do here in our side is, we use Toyota 1ZZFE or 1UZFE smart coils for 1000+ HP drift cars.
As well as in my IS300 at 22psi without a single hiccup. They have been working perfectly for awhile now.
Cheap and Toyota reliable.
Good luck!
Yeah I'm kicking myself for not just doing the 1ZZ or IGN-1A coils. It seems like some people have really good luck with the LQ9 setup, but I am already running out of patience trying to troubleshoot potential issues. I may just bite the bullet and swap to the IGN-1A coils because they are proven to perform well while being very reliable. Just stinks that I have to modify my brand new engine harness for different coils. Thanks for watching man!
I was never a big fan of the LQ9 setup for its known heat soaking and now you with the misfire at a relatively low boost settings. I went the 1ZZ route for it being cheap ($100 for six coils), and as well because it is very easy to find too.
I hope you will be able to solve the problem soon and shoot for 30+ PSI.
Good luck man, and keep the videos coming!
Great build man, I just got my IS300 a few months ago, not looking for these types of gains but damn your set up is nice!
Nice! Thanks for watching man!
Great videos.. Love the is300 .
Thank you!
Loving the videos man! I'm sure there will be a simple explanation to the ignition problem. I'm relocating to the USA in a few months and my first project car will be similar to yours. Love the car and your attention to detail. :)
That's what I'm hoping! Thanks for the support and good luck with your project!
Nice car my friend. I own a 2002 is300 sportcross.I love the looks of it. Hopefully one day is going to be a 400 to 500 whp daily driver.If i ever get it done her name is going to be "The Supra Wagon...
Do you do this stuff for a living or is it a hobby? Great content btw, I look forward to each new video.
im convinced... im buying an IS 300
I heard the IGN-1A race coils are the way to go, but yeah that's a bummer. I hope you figure it out, looks like it's still a beast!
Yeah after doing a little more research, I'm kicking myself for not going a different route as far as the coils go. Do you know of anyone that makes an IGN-1A kit for the 2JZ-GE VVTi? I found a couple kits for the GTE but they have different valve covers. Maybe I'll just have to find some GTE valve covers and do the IGN-1A setup...
Not sure about them being available for the GE but it'll look better with GTE valve covers at least. Yay for spending more money...
Very nice man! I'm sure you'll get the ignition stuff sorted out. Do you work at or own a shop? Pretty sweet that you have access to a dyno like that! 🤘👍
Thanks man! I work for a company that develops performance upgrades for diesel pickups. It is very nice to have access to a dyno for sure!
600+ hp is still enough to run circles around pretty much anyone in St. George who dares challenge you to a race. What are your plans for putting the power to the ground? Are those tires meaty enough to make the most of it?
600+ hooks up in 5th gear! Would definitely be fun to have a different rear wheel/tire setup to maximize traction for high power runs.
get some MT's and call it a day bro
I'm really happy for you man i should of built it when i had the money... now it's going to be slow going for the next year but after the move i'll start working on it going to put a e-cutout in after the header going for the sleeper look on mine so no point in wasting $$$$ on a turboback etc when i put the turbo on and head work in fall it will make it even better just doing supporting mods first like fuel system and drive shaft crank pulley , ecu and new na tune till boost etc.
hope you get it worked out bro and I do have to ask was it hard to paint your dash ?looks so clean ;] I'm guessing that black top coat came off of yours like mine did and that's why you painted it ?
Not going to lie, refinishing the dash was quite a bit of work. Pulling the dash out really isn't too bad, I think there are a few good DIYs on the dash removal process. Stripping the old sticky paint off was extremely messy and pretty time-consuming. The end result is well worth it though!
XtremeCoupe for everyone that didn't fix the sticky Dash problem if you use armor-all wipes it comes off really well
@two jay And I don't remember if you said this or not in a previous video, but is your intercooler powder coated or anodized?
@two jay What size is your intercooler? Length x Width x Height. And how is it doing with cooling your charged air? Do you think that you need a thicker one now or in the future?
we're does he get those wonderful toys.....got a dyno in the bat cave ....yuup
I used to use lq9 coils and had nothing but problems. I sold my setup for 1/3 the price I bought it for because I hated it so much and wanted it gone. Buy Ign1a coil packs and you won't ever have an issue again. I will be shooting for 1000whp with then and a .28 gap
Yeah I'm kicking myself for not just doing the IGN-1A coils now. Seems like the LQ9 setup is just totally hit or miss and that's not something I want to deal with. I want something that is proven/reliable and it seems like the IGN-1A coils are the way to go. Did you go with someone's kit or did you make your own setup? The Induction Performance Kit is really nice but I'm guessing I'll have to get some GTE valve covers for it to work.
Oh I hear ya man I spent 800$ on my lq9 setup and ran into nothing but trouble making 740whp one time but the curve was not smooth by any means. I'll have a wire harness for sale very soon for Ign1a if you need. I bought wires and bracket from induction performance
Yeah seems like the Induction Performance setup is the way to go. What EMS are you running? Do you have any idea what you're commanding for dwell with the IGN-1As? Why are you selling the wiring harness just out of curiosity?
Not sure on the dwell settings I don't even have my base map setup just yet I had started the car with the lq9 ignition settings just to get it running. I have a proefi 128 and it was wired to fire out of each of the 6 ignition outputs directly from the ecu. Selling my harness because I just ordered a tweakd engine harness that includes Ign1a plugs. You could also convert your lq9 harness into an Ign1a by sourcing the clips for it. I know it's been done before
Oh nice. Yeah the thing that stinks is that I just barely had a custom engine harness made for the LQ9 coils (made by Tweak'd as well). Maybe they can just modify it for IGN-1As or I can do it myself like you said.
shame about the ignition system, was there any particular reason you swapped out the standard lexus setup? also what sparkplugs are you using and gapped down to? eddie from the griswolds making an appearance too 😂
Hey Robert,
I changed the ignition system because I assumed the factory IS300 setup was nearing its limits and wanted an upgrade that would be good for as much power as I could throw at it. Little did I know that these LQ9 coils are absolute junk (so far). I'm running Denso Iridium IK27 plugs and had them gapped down to .020". These are the same plugs and gap that I have been running for a couple years without any issues (with the stock IS300 coils)
Haha, glad you noticed Cousin Eddie!
XtremeCoupe thats great thanks matey 👍 so once you have this issue sorted how far in terms of boost pressure are you going to turn it up to? yeh i love the griswolds especially the christmas vacation, we put it on every year it just never gets old 😂
I would REALLY like to push this thing to around 30 PSI and hopefully get over the 700 WHP mark!
Christmas Vacation is must-watch every year for sure!
Have you thought about running the M&W Pro 16. When I use to work for Real Street. That's what they used.
Hey Robert, I'll have to look into that. Thanks for the info!
Any boost response curves of the two turbo's?
What does this turbo make on pump gas?
what head haskell are you using and are your pistons 8.5:1 the piston how dose the car feel off boost?
I'm running a stock GTE headgasket in combination with 8.5:1 CP pistons which probably puts my compression ratio between 8.2 - 8.3:1. Even with the compression ratio that low, the car is plenty responsive when out of boost and spools very quickly with the EFR 9180.
18th time watching this vid. As ii finally solved my ignition issue. And alexis is pulling 8psi solid without spark blow out. It was my coil wires being exposed and causing some electric shrort under boost. Hope you got your issue sorted out my dude
Thanks for the info! So what did you do to solve the issue? Wrap the wires in something?
I soldered in new pigtails and covered the wires with thicker sleeves.
XtremeCoupe any voltage drop from alternator at wot at higher psi?. Just ran into that issue with a dsm. We thought it was ignition box, coils, and it turned out to be alternator.
What was voltage dropping to? I typically see around 13.5V under WOT but have always wondered if the stock alternator is sufficient for 2 big fuel pumps, 2 ECMs, tons of gauges, etc.
what does the car do 0 to 60 and quarter mile? I have a stock sport cross 2002 and just starting to think about what to do
Hows the sportcross doing? Thinking of getting one.
did you try messing with the ignition dwell?
Yeah, I pulled dwell down to around 2.0ms and still had issues.
Did you figure out the issue? I'm dealing with the same BS on my VVTi GE turbo is300. ProEFi setup. Changed plugs, put in new coils and coil packs, going to test a spare working igniter next to see if that's the issue.
Very annoying. Just got it back from the shop and put down 600+whp, and now this shit's happening. :(
You're using LQ9 coils with an igniter? That doesn't seem right.
No. Stock coils, stock igniter, GE VVTi motor.
As far as headwork, anything done? Stock cams?
Just BC valve springs, retainers, and 272 cams (stock valves, no porting).
Do VAG COILS
I'll look into it, thanks for watching!
Is this engine the stock 2jzge engine or is it the 2jzgte?
Neither. It's a built 2JZGE.
Oh tight you bulit the ge yourself
Yep!
hey bro love the build. Im doing one myself as we speak. Ive been doing a bit of research and i stumbled on this website that talks about the common problems with the LQ9 coils. Im just showing it to you in case you havent seen it, maybe it helps with your issues with the coils...apparently people are running 30-40 psi without problem.
mojoperf.com/?q=node/5
Hope this helps
Hey man, thanks for the link! I'll check it out and see if there's any new info. It seems like there is a huge discrepancy between LQ9 users, some have great luck while others have issues similar to mine. I may end up ditching the LQ9 coils for something newer and more reliable (such as the IGN-1A). I don't like worrying about possible engine damage with misfire issues.
