junkyard turbo's

[powerjunkie]

im thinking about building a turbo'd 300.

i see turbo's in volvo's all the time at the junkyard. From what size volvo engine would be the best turbo to use on a 300?

im not looking for huge numbers or anything. i just want to say i have a turbo under the hood. (everybody likes turbo whistle)

I think anything in a volvo (or saab, another plentiful turbo in junk yards) is probably way too small for a 300. If you are brazen enough, you could do a twin turbo setup, but that is going to open up a whole new can of worms (literally) with all of the piping that you would have to do. I am sure some other members will chime in soon with their opinions also. If you can find a turbo diesel, truck, then maybe that turbo might work. I have heard that a turbo from a diesel engine twice as big as the intended gasoline engine is a good starting point. I am not sure of the validity of that but its what I have heard. Hope that helps

so a volvo/saab turbo wouldn't even give me a couple of pounds of boost? or would i just be burning the turbo up from my displacement?

the volvo engines are pretty small
here's a thread about VW 1.8T turbos
http://fordsix.com/forum/viewtopic.php? ... highlight=

somewhere in there it mentions that the Super60 turbos from the thunderchickens might work if you rebuilt them with bigger housings

worth a thought

GM 6.5 turbo seems to match well with the stock 4.9.

Do a search on ford-trucks, there is a write up with dyno information.

At just a couple lbs of boost it wouldnt even be worth the effort.

I've see them set up as twin turbos on some of the Aussie Falcons.Would have to be a twin set up to work.

 

[yodabiri]

There was a person who was modding a 67 mustang for twing turbos out of a 2.3 mustang (if my memory serves me correctly), maybe they have had progress.

 

[powerjunkie]

cool. thanks for the responses guys! ill look for some bigger turbo's at the junkyard.

The 98.5 to 2002 Dodge Cummins with a manual transmission had a Holset HX35. That looks like it should be good up to about 4500 rpm and 400hp. The automatics had an HY35. From what I've heard, it was an HX35 with a smaller exhaust housing. I would think that you could find both fairly easily. Either turbo should make loads of torque, but from the maps, they won't like high rpm. The 2003-2004.5 H.O. might be good for a little more, but I'm not sure of the exact specs.

 

[JGTurbo]

I ran some more tests and it looks like the HX35 would work even better on a 250. I have seen these turbo's boost the 359 cubic inch Cummins to 40 psi at around 1800 rpm. It seems like that would be about right size of turbine to get a 250 cubic inch engine up to max boost at around 2500rpm. And you've got the two factory sizes of housings to choose from to fine tune it. TST Performance makes a larger housing as well. But on a 300, you could boost it to 12 psi at 1500 rpm and the turbo still wouldn't surge, so you might as well take advantage of the smaller turbine housings and make some killer torque. Dang, this turbo looks better and better the more I research it. I might have to give this a try....

well my 1st turbo set up used one turbo off a 80s turbo probe 2.2? out of the junk yard. there was only the motor not body at the junk yard.

doesnt look that good but for free it worked.

 

[powerjunkie]

cool guys! i went to the junkyard today. they want 100$ for a little volvo turbo. they wouldnt part with any powerstroke turbo's. and i couldnt find any 2.3 turbo's there.

so instead of getting a turbo, i bought a bench seat (wayyy better condition than my old rag covered seat) for 50$. i had 20$ credit so it only cost me 30$. so i guess ill start saving my pennies for a turbo.

has anyone tried nissan turbos? from Z cars? i found one that has the turbo still in it.

ya that 6.5 diesel turbo worked pretty good for this guy http://www.ford-trucks.com/forums/250890-just-turbod-my-300-six.html

ive heard many guys taking about twinnies in the 300 since the 300 like the low rpms like below 3500 twin turbos wouls spool up quicker and give you more boost in the lower rpms ya its a bit more plumbing but if i were to do it (which i am) i would build a seperate intake box on the passenger side and run both turbos off that

 

[wallaka]

Eh, just get the right A/R exhaust housing and a single will spool just as fast. Yeah, there's more inertia there but there is twice the exhaust volume moving against it too.

 

[9.ford.5]

so for this engine you should look for something with a smaller turbine A/R then right? since compressor A/R doesnt do much

 

[powerjunkie]

well my whole budget changed. i got another truck of the same year. im putting another 300 six in it. so im spending my money on fixing my new truck up. i dont have time anymore to even think about a turbo.

 

[86F150SIX]

so will a turbo from another inline six (diesel) like a Dodge Cummins work on a gasoline Ford 300?

It seems too easy to me, just go to the junk yard and pick up a used turbo out of a diesel, and then just do the proper mods to the truck and its done.

 

[XFlow_Fairlane]

I would find a pair of IHI turbos off a probe or thunderbird.

they are cheap and would be about perfect on a 300.

 

[michael_cini]

great topic guys. so, what single junkyard turbo should i look to use in my 250 I6?

thanks.
