Like to see something different.. From what I remember, the draw through turbo setups always have a different sound..(old turbo 1 dodge 2.2)

From the thread that had all the calculations I came up with (257.9 x 4500) / 3456 = 335.81

335.81 x .80 = 268.65 cfm

I'll start looking through the turbo maps again and see what will work for me. I'm still leaning toward the t3/t4 combo for availability and for the quick spool/big boost.

I know there are some videos and pictures of my rig floating around but none that I know of on the internet. Here is a random photo for a little rock garden at our local stomping grounds. Tillamook State Forest, Oregon.




I also have another Land Cruiser project as well. It is a 1964 FJ45 LV Land Cruiser wagon. I put a '04 6.0L Chevy Vortec, 700r4 tranny, spring over rear, 3 link/coil overs in the front, 315 (35") Toyo tires, Power steering, tube fenders, air conditioning/heater, and whatever seats that will fit inside that have a built in heater

Okay talked with a local turbo place in Washington and he had me call Turbonetics. They suggested a t3/t4 e50 stage 5, .48.

Personally I don't want to be spending $900 on a turbo set up. Are there any places that sell rebuilt turbos that will have this set up?

try blaast, who is a sponsor on here. he rebuilds turbos and has a lot of rebuilt ones in stock for sale, and can definitely recommend the right turbo to you. I'm telling you, you should really check out some of the holset turbos. There are some compressor maps on honda-tech if you do a google search for them.

I started looking at those as well. Called a place and the guy recommended a HY35 that came out of the '00 - '01 Dodge diesels. He said the HX30 would be a good alternative as well but thought the HY35 would be a little better for my application. I found some compressor maps dsmtuners.com so I'll keep digging around.

here you would get a accurate vacuum signal from in a boost application, even if you had it between the mixer and the inlet of the turbo.

btw fwiw, i had no problems with the ranger, except for 1. i kept blowing out the gasket between the mixer and the air hat (huge *** super sticky windshield sealing tape fied that. then 2. that created the problem of it ripped out the stud that mounts the hat to the mixer out of teh mixer (its only aluminum and was hitting 24psi). 3. had too small of a tank (8 gal forklift) and not enough places to fill it.
Doing a draw through design would replicate how my set up is currently right now. Currently the entire set up is being run off of engine vacuum and by putting the mixer on the suction side of the turbo it is keeping the same characteristics. I believe for a blow through design you will have to run a vacuum tube from the mixer to the vaporizer. So under boost that vacuum line will travel to the vaporizer diaphragm allowing it to open up more to let larger amount of propane to flow through.

Here is a link to the one off turbo propane set up that was set up originally in Australia. He is using a straight t4 with an external wastegate. I am deciding between a t3/t4, HY35, or HX30 and I want to use an internal waste gate.

the hy35's are a little harder to come by because they are newer, but the hx35's that came on the same trucks in the years earlier are very similar. From my understanding, the hy35 is slightly smaller and a lil bit more efficient, but the hx35 is not far off at all, and a very popular turbo around HMT. Different size exhaust sides came on different trucks depending on the year, whether it was auto or stick, etc so there is room to play, and there is at least one company (bullydog or bulldog?) that makes a different aftermarket exhaust side also.

heres one build with an hx35

Joseph Davis is using one for is 500hp build if he ever finishes it, along with a lot of other people if you ask around
