Bolt on turbo kit (6 Viewers)

To the issue of CARB compliance - Are you planning to sell kits prior to getting the approval or are you going hold off until you have it in hand?

Since so many of us are in non-referee/smogged areas, a CARB plate wouldn’t mean a thing either way.

To 16 states it matters. But it will likely be determined before certification if any physical changes will need to be required. I’m not doing two kits so trying to keep everything within the requirements.

yeah, Yuma doesn't care. you can label it for "off road / race use only" that way people in California can register their vehicles as farm vehicles. problem solved...

^^^^
I get Joey’s method - KISS / no version 1.0/1.1 business, just wait & make ‘em all same-same.

I've said it B4 it's done when it's done. And the more time spent in the R&D the less complaining later.
So thank you for time spent so far !

Just some quickie updates:

• As of this morning I've ordered a big ole batch of Turbo J-pipes. Looking at between 7-8 weeks for those.
• Wits' End is officially a SEMA member so s*** is definitely getting real!

The 1FZ Turbo Oil Drain Fittings are done. They are all machined, anodized, etched and each has its alignment dowel. Now I need to order up the hardware, AN fitting, AN cap and drill & tap. Why drill and tap? Because it’s a funky size and I’ll be supplying the tools needed to make it install properly.

Where are the intercoolers?

 

[jjdeneen918]

About those intercoolers....placement.

Any idea on placement. I’ve been looking at other builds, but many are air-to-air. They have been above the engine, making good scoops enticing.

Any thoughts, or R&D, on where it might go?

Not sure if water-to-air would benefit from forced air, or as much. Fluid dynamics wasn’t to forte.

The only intercooler design I am interested in doing is an air-to-water and it’ll be on top of the valve cover. There are several reasons for this:
* placement- the accessibility on top of the valve cover is much easier to work with than the front of the grill.
* hoses- running 3/4” flexible hoses is a ton easier than running 2.5-3” aluminum air tubes around the engine bay.
* production- doing a one off for the grill is a very different animal than making a production piece that everyone has to use. On my end it’s easier to have a base core and just laser cut aluminum pieces that just need a good tig welder
* cost- all things considered it’ll be less expensive on the production side
* effectiveness- this I don’t know conclusively. I refer to those that have done this many times over.

As far as the actual production unit(s), nothing has been started because I need to complete the Turbo kit first AND I need to get a full understanding of demand. If demand is good, I’ll continue to move forward. If not then someone else can jump right in.

Air-to-water is the intercooling route Toyota went with the new 200t and its fantastic and compact. The IS200t made me fall in love with boost. Also, I think this method is wise considering the speeds we run on trails. Is there a plan for efans to assist intercooling at low speed?

 

[scottryana]

@jjdeneen918 There is zero benefit to using a hood scoop over an Air-Water intercooler. The cooling is 99% done inside the cooler by the water. The air flow has to go over the heat exchanger, that would be mounted up front in front of the radiator.

@Twinair I agree for the way most people think they want to use their 80's the AW intercoolers work great. On my truck I have a heat exchanger with a SPAL pusher fan and it keeps things nice. I would use a different intercooler if I were to do it again but all in all it works well.

Forgive my ignorance, but I thought the intercooler was the heat exchanger. Are they 2 different components?

Joey said the intercooler would most likely be over the valve cover, but Scott you mentioned the heat exchanger going in front of the radiator... picture references the same.

 

[scottryana]

They are 2 different components. In an Air to Water intercooler you also have a heat exchanger that cools the water.

Different engine but basically what you are looking at.

Awesome diagram!

I’m still learning about all this, I’m sure I’m not the only one. Good tech chat.

I assumed the water/air intercooler just plumbed via the cars radiator & used the engine water pump to do the work. Totally wrong & ignorant on my part, but makes sense now reading.

Turns out it’s totally independent system. Separate water pump, radiator, etc..

I found this YouTube video that I thought explained it well..

 

[scottryana]

Yeah I think there are some diesel systems that are setup using the car's radiator but you would definitely not want that in a gas application, the coolant temp in a car's radiator is much hotter than you would want your intake air temps. Using the separate system you get air temps much closer to ambient than the car's coolant at 180-190f.

Plus routing garden hose is much easier than routing exhaust pipe under the hood

 

[Mandrake]

The W2AIC system in my Jaguar is siamesed to the engine coolant system for both filling/burping and expansion purposes via a 1/2" ID hose on the cold side of both the radiator and IC heat exchanger. Many people have added a separate reservoir amd divorced the systems, only to report no change in IAT2's. And before it's efficiency is brought to question, the system is quite good- with just a thicker heat exchanger, it's supporting 650+ hp for me without any problems.

A tee in to the existing cooling system might be easier than its own reservoir when you get to that point...

 

[Heckraiser]

No way this kit will be altering/modifying the looming monster in the back reaches of every OCD mudder's mind, the factory cooling system. Bad idea.

Separate system allows anyone to use with no modification it if they choose, or try their own thing at their own risk.
