Good feedback, because I don't think an inter cooler is going to work clogged with buckshot mud. no way to use an under the truck breather in hunting use. I'm not sure about that radiator-looking oil pump/cooler getting coated with mud either. I have seen this setup on Camaros for street use but not for off road use. I enjoy driving my wife's X5 turbo makes that vehicle an Ultimate driving experience but how do you get similar low end turbo boost for the 4.5L Toyota?

2K keep up the good work. There's plenty of members watching this thread as a viable option for forced induction that can be quickly taken back to stock.
I too am interested in your package but am trying to give you real feedback on what on/off road 80 users want out of such a package. You've done a great job of exploring our options here! I need quiet, more fuel efficient, durable power options. I think that's what will make a profit for you.

Thanks guys! It works for what it is. You can obviously custom make a snorkel if you are running into a lot of water or just simply remove the turbo. Not looking for selling these in big numbers. I don't know if I would even have the time, just thought it would be cool to do and luckily it worked out great for me.
Mine sounds like your videos and its totally stock.. Well actually it sounds like a bunch of damn cicadas.. thinking its the resonator. Anyway, I'd be interested in the lower cost option and install myself. I'm hoping the numbers would be similar to the yota supercharger which would make this a great option at 1/2 the cost.
So.....what turbo would you recommend for a v8? would a turbo from a cummins 5.9l work well for 5ish liter motor?
not saying I don't have enough, but in my book, more is better and i have the means to tune my fuel/spark maps easily.

Compressor mapping is done based off of displacement size, rev range and desired power. Without a little more info anyone would just be giving you guesses.
i.e. a 2L four cylinder that revs to 10,000rpms and wants to make 800hp would use a bigger turbo than a 5.9L cummins that revs to 3,200 and makes 200hp.

Yes dual turbo systems sequential or compound are expensive, because you're buying 2 of everything (turbos, wastegates, blowoff valves, turbo controllers, oil lines, water lines, etc) and they are difficult to get dialed in. I think most people just looking for a little extra power will be really happy with a fairly small single turbo, since it will have minimal turbo lag and will meet their power requirements. I know EMS has a lot on their plate but their system sounds like it will be very modular allowing the end user to pick their turbo and accessories based on power goals. Lilevo's system is also well documented and produces double stock power. As soon as we get some numbers we can see where 2kcruisers system fits in.

Well, its a 5.3l, , max rpm is 6k, shooting for ~450 hp so as not to overwhelm the 4l60e. I have plenty of torque so this is just an exercise in boosting the fun factor.
I will run the numbers when I get back to the house but you could probably run any of the small turbos (PT5862,6262, GT30, GT35, BW7067, BW7670, etc) if 450hp is your goal. Is that awhp or flywheel? Big difference. Lilevo is 300awhp probably close to 400 crank hp.
One of the challenges with a V8 motor and single turbo is where do you put the turbo so that both exhaust manifolds have equal length runs? Most guys do a front mount but I am not sure how much room you have up front.

Ok running the numbers I was off. The smallest turbos run off the compressor map at 5,000rpms running 10psi.
SO you would be looking at: (smallest ---> largest)
Precision Turbo - 6262, 6266, 6466
Garret - GT(X)35, GT(X)40
Borg Warner - EFR7670, EFR8374
All of them would meet your goal at fairly low boost levels, stay on the compressor map, rule of thumb the smaller the turbo the earlier in the rpm range the torque comes in, larger turbos spool later but make more power. i.e. the Precision Turbo 6262 is a 705hp capable turbo while the 6466 is a 900hp capable turbo, of course you wouldn't run them that hard.

I was thinking of experimenting with a rear mount turbo just like the OP did. Doesn't look all the difficult and it's easy to go back to stock. I am looking at crank hp because thats the number I need to watch for transmission protection.
Be careful 2K, you might just sell a ton of these if the numbers back it up. Lot's of interest around these parts.

Yeah, hoping to make some time to run over to the dyno soon. I will most likely keep the smaller turbo in during the dyno or maybe take the larger one also and swap it to see both numbers. Then I can see where they both start spooling comparing A/R, compressor and wheel sizes.
