So Ive got a rampage, this is uh... rough. No rust, but its had a hard life. I brought it home after it had set for many years. Rebuilt the carb, added some fresh gas and it fired to life, but spun a rod bearing 3 days later. It was pushed behind the shop, and dreams of a high HP power plant have been dancing in my head. Turbo 2.4's, a NA or boosted 3.0... or maybe even a high compression carb engine. But, like most projects money and time are always the problem.
I also had intended one when I first got it, to convert it to propane. Gas was 4+ a gallon and propane was $2. I did alot of research and found it was actually a cheap conversion due to the propane powered schwans trucks that are in the local JY's. Propane also has a octane around 105 so a high compression motor could easily run on "pump" gas. I also stumbled upon a website, that had propane powered toyota rockcrawlers. A few of them were running suck-through turbo setups... The high octane made the propane and boost a great setup.
So, after thinking about it, why not build a turbo 2.2... that runs on propane? I have all the parts to build a decent motor, a turbo, tons of easily converted log parts... Just makes sense!
So here is what Im thinking...
*use the rebuilt 84 turbo bottom end a guy gave me a few years ago, never been ran.
*use my g-head that has backcut valves and was rebuilt a year or too ago, to only run 3 miles before the oil pump seized, resulting in my tona getting parted.
*use a log intake/turbo with the injector holes welded shut, and smoothed out inside. Should make the intake flow better without the injectors in the middle of the port.
*then lastly, remove the factory TB from the turbo and build a nicer, freer flowing piece that would allow me to bolt on a propane carburetor.
Sounds simple enough, although as a whole it could be improved on. I have all the pieces aside from the propane bits, and even new they are not very expensive. I think 200+hp would be attain able and would make the l-body truck fly! There a few more factors to be considered, mainly spark control. So... what do you guys think? Do able?
