Events/Trails DIY Turbo V1.0, Boosted 80 = Happiness

[nigelsiam]

All of this waiting is making me nervous...and giddy. Nervous because it's going to make me part ways with my cash so easily and giddy because I will be smiling non stop when I get this installed!

Let's go!!

I'm thinking early spool up better for mud. Is there another way to do the oiling system without putting it under the truck?

Haha! I felt the same exact way when I began this little project of mine. My wife was like shut up about your turbo already. LOL

Yes, I already made that change, remounted all lines on top of frame. Removed the oil reservoir tank and now getting ready to order some turbos with ball bearing internals for even quicker spool.

Assuming your engine is otherwise stock, would the injectors and fuel pump likely be limiting factors for top end power here with your turbo set-up? IOW, if you are otherwise at the max that the stock engine can produce safely with your turbo set-up, could you bump this up a substantially more with just changing injectors (e.g., STI) and fuel pump (e.g., Supra TT)?

I am just thinking of next steps that would still keep this simple (e.g., no new engine management).

 

[2KCruiser]

Yes, of course. These motors as many you have built them know that they are capable of pushing over 1000hp. However with stock internals and some mileage on it, I feel very comfortable boosting all day long with my setup and not having to worry about having a hole in the side of my block. My AFR is reading great numbers, so I am not even close to leaning out. So I do plan on adding some more boost until the ECU tells me NO. But again, the way it sits now is more than enough power compared to what it use to be. By not changing injectors and pump you are saving close to $1500+. That's what makes this setup so great.

 

[Backwoods Rambler]

How would the AFR #'s be affected by altitude? Some folks could be making 11k+ foot climbs with their rigs.

 

[2KCruiser]

That's what turbos were original designed for. At high altitudes the air in less dense, lacking oxygen, so the turbo compresses the air making it more dense and cramming it into your manifold eliminating that lose of power.

In aircraft it's still commonly referred to as turbo normalizing when you return the engine's performance to its sea level base line.

 

[2KCruiser]

Exactly, they started using them in aircraft motors more commonly I believe during WWI.

Cool. Thanks. I thought you were intimating you were somewhat approaching to the stock limits (e.g., of the injectors and/or pump) but wanted to go significantly further. I also did not know the noted injectors and fuel pump were that pricey. Excellent to hear this about the remaining additional "headroom" apparently available. Cheers.

 

[scottryana]

Damn 2KCruiser, you need to find a new place to buy injectors and pumps. The 440cc injectors and Denso pump are only $600.

 

[2KCruiser]

In my field, most race injectors are $150+ each and Race pumps start at $300+.
I was not talking about factory upgrades.

 

[scottryana]

What race injectors are high impedence 11mm, and bigger than 440cc and fit the 80 series? If you have found some I would love to know. Which race pumps? Walbro 485's, and Aeromotive's are less than $180 each and the 80 only uses 1.

 

[2KCruiser]

Was not specific on application, just general speaking here.

 

[2KCruiser]

Actually if you replace the injectors and pump, most likely you will spend more than $1500 since you are likely to install an engine management system as well.

 

[scottryana]

Damn thought you might have some inside lines, I have been looking at aftermarket injectors until my eyes have crossed. The 440cc injectors are about the only option in this size. Also looking at a 540cc 3S-GTE injector, but the hi impedance and 11mm inlet size make them fairly rare. As for pumps, Denso, Walbro, and Aeromotive will all work and supply 300-500hp at the wheel worth of fuel @$180-230.

In my opinion engine management should be done before injectors and pumps regardless.

 

[2KCruiser]

Did you try RC Engineering?

 

[scottryana]

Yep, they said their SL4-0550 might fit but they don't know since they have never tried it and don't have any data on the 1FZ-FE motor. So I would basically need to drop the $600 to be a guinea pig. I think I will try the 540cc 3S-GTE injectors.

 

[2KCruiser]

Exactly why my setup is so sweet. No need for all that extra work and $$$.
Brushing off my own shoulders...

 

[scottryana]

Yeah I guess that is one way to look at it. But we still don't really know what your system does for the price.

I mean you're only 14% faster, while lilevo that did the extra work is 108% faster in 15-60mph pulls.

I guess for me it really depends on the Return on Investment, for me is $3000 worth 14%? My ROI to do the turbo meant I have to make 300awhp or it isn't worth the effort, time and complications. You have a lot of the system in place all of the expensive things, why not just wrap up the small things and see some real gains?
