can you put a deisel turbo in your car that run on gasoline? i heard about people using school bus turbos....i am curently in japan and they are trying to get ride of all these deisel vans..it's part of this clean are law that they are putting in and i figure i can go to a few junk yards and juss rip out a bunch....but would it be worth it?!?!

 

alot of diesel turbos are not wastegated, take that into consideration, prolly lag like a mother too.

 

i was driving around my unlces van last night that he is about to junk and i was asking him if it was koo if i rip out the turbo and he said it was koo and while i was driving it i heard it spool up pretty early...i juss wonder how it would in a gasoline ran car....i think the big turbos on thoes big trucks lag like a mother but these smaller ones on these lil vans should work fine for what i want with my car

 

Well depending on the vans engine size, ,mine spools fast simply because it has 7.3 litres of V8 feeding it, but put that behind some 4 banger, it likely would never spool at all.

 

these vans are 4 bangers.....i'll ask around over here....thanks for your help tony

 

If I remember correctly the mapping of the exhaust and intake flows and temps for most diesel turbos do not favor gas motors.

One of the biggest differences about a diesel motor most people are not aware of is that a diesel does not have an intake throttle.

From an intake perspective it is always WOT.

Another difference is that the fuel is also not injected or mixed during the intake stroke. There is an injector that uses hundreds or thousands of PSI to squeeze fuel into the cylinder when its time to make power and the piston is almost to the TDC of the compression stroke.

The 'throttle' on a diesel only effects how much fuel is injected.

Since a diesel is a motor that runs on spontaneous combustion it wants a hot wad of gas to spray some fuel into. Pressure = Heat which is the reason why each intake stroke wants to get all the air it can.

For these reasons a diesel will normally flow a certain amount of air for a certain RPM and the only thing the load changes is the average temp of the combustion gasses.

In a gas engine the heat of combustion per volume of air is fixed, but the amount of air the engine is fed is varied to control power.

Since turbine and compressor maps are combined and optimised based on things like volume, pressure and heat all these facts combine to make most diesel turbos specialized to their application.

I would not be suprised to learn that there are some that might be suitable for a gasoline engine though.

 

Tony, my injectors fire at 24,000 PSI (inside the injector) from the last article I read, most old school pure mechanical setups run somewhere around 10,000 psi of line pressure. You are told to check for leaks with a piece of cardboard, if it cuts it, you have a leak, it will also cut your hands with the fuel pressure.

 

Powerstroke Kicks Ass

Its about time the equivalent of the electronic fuel injector was made for diesels.

Actually to be honest, all of us powerstrokers hate the EFI...each injector is 250 bucks...LOL But they do make for easy mods, i mean I did a downpipe, and reprogrammed my PCM with a superchips plug in to have an instantaneous 300hp and 600 ft lbs...self tuning can be fun, but when a cam sensor goes south on the interstate, or rather at the front gate of base *cough* leaving the truck stuck for a second to reset, one likes the mnechanical setups. I wish my truck had a cummins, but it would be slower.

 

Mechanical injection systems take a shit every now and then too.

Take it from someone who is now having to work on diesels for a living.

I would take an EFI system like the powerstroke over a mechanical distributor system anyday.

A MFI for a diesel could easily set you back thousands.
