Bolt on turbo kit (6 Viewers)

[scottryana]

I am sorry guys, but to give you any kind of timeline would be nothing more than lip service by me unfortunately. The person that took this project on is definitely moving forward with it. They have bought a 1FZ engine for mock up, they are getting the 1/2" flanges water jetted, they have purchased some of the turbo parts. It is moving but it is not their only project and I assume it isn't even their #1 project. Worst case scenario the kit doesn't happen but we get a lot of good data or even some individual parts. This guy is a well known Toyota character and I know he is reading the thread so best thing you can probably do it show support and perhaps any ideas you might have and hopefully it will give him that extra push.

Hey Ryan, how close are you getting on this? I'm anxiously awaiting. Engine rebuilt and balanced, ARP studs, cometic HG. Now all I need is a little boost!

I think it is a great idea to put a bolt on turbo kit together with quality parts at a good price point! There should be quite a few buyers for it. I'm a fairly competent guy when it comes to mechanics, but I have ZERO experience with turbos. I want the extra power for the hills in the PNW, but the idea of piecing together my own turbo kit is intimidating. I also don't have the time to do the proper research or redo anything. I'm sure there are a lot of guys out there that are similar. The idea of buying a quality kit is very exciting! Hopefully this comes to fruition. I am definitely a buyer.

Ryan, I have been wondering for quite a while when you were going to do this, with all of your work on your two LX450's and your knowledge it seems like a natural progression. Thank you for spearheading this! Hopefully you can get something for your efforts. I'd be happy to buy you a beer anytime.

Show of support:

I am going to re-turbo my truck one of these days, maybe next spring or next fall? If this kit is available whenever I pull the trigger (i.e. when I catch up on my deferred maintenance), I will buy the sucker. If it doesn't leak exhaust, my wife will send the creator of this kit a bottle of his favorite booze or gift basket.

AZ folks, can it be registered there? Thanks

I've been reading a lot on some AU sites. They seem to have a lot of turbo experience on the 1FZ. Have you been looking across the pond as well to see what they are doing? I recently ran across mention of the Camtech camshafts and they look impressive.

How big of a problem is the twin scroll turbo? Is it just too expensive to overcome the closed/open loop issue on a basic turbo kit because boost comes on too soon and she leans way out? I guess this is where we get into piggyback Haltech systems and things get spensive.

 

[scottryana]

The AU guys have a very different ECU than we do in the US, they do not have OBDII, things are very different with their trucks. I have been part of the AU turbo group since 2015.

Twin scroll is not a big problem, my silver truck is twin scroll. But we are talking about using the best turbo possible within the constraints of stock ECU. Using a cheaper cast turbo, I was going to use twin scroll, but with the new CNC wheels and investment cast BW turbo, I think it would boost too quickly for the stock computer. Again if we were building the "BEST" system it isn't how I would do it. But we are building the best system we can given the constraints of the stock US computer.

If you want to go buy a standalone ECU, a CNC ballbearing turbo, a 6boost manifold, and a Hypertune intake manifold, and lets get busy building a serious system. But those 4 components alone would cost you $9000.

Yeah this would be a great solution. Looking at a rebuild soon and am considering the 5.3 vortex swap. I really like the 1fz but the lack of power in the sierra while climbing hills is super frustrating. Nothing like being stuck in the semi-truck line on Hwy 80! How feasible would it be to reverse this for a smog inspection

Good to know. So I often see on my Facebook feeds high mileage 1FZ AU motors with ECU for sale from $800 - $1500. You are saying this would open up a whole new world of options with the non-OBDII ECU? Or is there a list of issues with this idea that are more trouble than they are worth?

 

[scottryana]

That I couldn't help you with. There is a guy doing a late GENII 1FZ here on mud, he is using a non-US ECU, and might be able to give you more information.

Will the AU ECU work in a US spec FZJ80/1FZFE, and if so, what would the advantages be? What would not work, the EGR system?

Or, is it possible to physically (components/firmware) modify a US spec ECU?

If you are running a non-US spec ECU then you will be tossing the EGR system in the bin. That much I know.

@scottryana please stop it... just stop with the updates on this thread.. and get your focus back on track with the black truck. That's all

Black truck is on hold for a little while. I am broke. Haha.

Interested. Subbed.

Its pretty easy to registrar anything is AZ. All any OBDII vehicle needs is a clean CEL and a good gas cap, they dont even look under the hood.
FWIW - I have a turbo 80 reg in AZ

Let me get this straight.... you have a turbo in the same rig as your CAMPTEQ?

Bro, we really CANNOT be friends, my jealousy runs too deep. Hijack over.

No no another 1997 White locked 80 turbo'd at dealership day one part of a joint build venture of a Washington Toyota dealership featuring Man-a-Fre, Safari, Warn, Kaymar, and ARB.

I wish the US wasn't as strict on the whole emissions thing. Where I am there isn't any rules about anything emissions related but with the restrictions in the US there isn't many real all out hp builds with standalone etc. back to the gtr derailment I've had a r32 and r33 and they were both cheap but fun cars. The guy who works for me has had either 9 or 10 r33s and he only makes $400US a week. He used to literally change his gearbox or clutch in under an hour on his own where he had done it so many times. The supply of reasonable skylines is drying up in Japan so they will very soon be a thing of the past. No idea where I'm going with this post I've been drinking for hours and it seemed I had some kind of direction when I started typing but I'm going to post anyway
