Initial steps .... Garrett turbo and 3" exhaust.

This was all made possible by the creative mind of Rob Smith Fabrications.
 
Nice work, interesting intercooler placement! Do you have any heat shielding between it and the exhaust to help prevent heat soak? Also how did you support the weight of the cooler?

The black bracket in this photo as well as in post #5 both supports the Intercooler and serves as a heat shield.
 
Definitely a unique setup! Nice to see new ideas.

How do the heat exchangers behind the bumper get air flow? Hard to see from the pictures.

No two of Rob's designs are the same. He designs and installs turbos based on your unique Cruiser / engine and takes into account a number of variables not limited to but including your driving style. Most of the components are fabricated in house.

Due to lack of room, placing the heat exchanger in the grill was never a viable option. It was decided that the heat exchangers (2) would be placed in the cavities on the outer portions of the brush bar. The original idea was to install rock guards on the backside of the heat exchangers to protect them from tire debris. To continue with the process, small air scoops would be attached to the tops of the rock guards to force air across the exchangers. Both designs were installed and for some reason the exchangers ran much cooler without the scoops. The theory being that the "flat nose" of the 77 Series forced air downward over the back side of the exchangers and enhanced the cooling process.
Hope my explanation makes sense.

There is a 2" gap between the heat exchanger and the rock shield and for reasons I can't explain the downforce enters this gap and cools the exchanger.

We went through all of this trouble to make sure my Cruiser didn't look like this. I'm not a hood scoop kinda guy. :)

The shop installed an under hood lighting system so I could admire their handywork in the dark. :)
 
Observations after approximately 2 months of driving with the newly installed Garrett turbo and Intercooler.............

1) The Garrett turbo spools up amazingly fast ... The boost is almost instant.
2) Temps. have yet to exceed 850°, with the average cruising temps. in the 600°-700° range.
3) Fuel economy averages 19mpg.
4) With the 3" exhaust, the 1HZ has a nice "burble" while accelerating.
 
I'd really like to see how this setup handles long hard hills like the coquihalla in BC here

Have you tried towing much to see how it affects the temps?
 
Although I'm not familiar with the altitude changes in Western Canada, on my recent trip to Tennessee I did encounter constant grades that stretched for 4-5 miles. On those hills the boost would settle in at approximately 10-11 psi and the temp. never exceeded 850°. I've never towed anything and probably never will. **

x2.

Toyota engines seem to have a sweet spot of sorts between 2,000 rpm and 2,600 rpm, particularly six-cylinder ones. That range is also soft on fuel consumption.
