I have a older aftermarket turbo kit for a my 6.9 and i am just confused about its setup. It is a kit where the turbo exhaust inlet bolts straight on the exhaust manifold. I dont know exactally how these kits work, but there is 2 outlets on the exhaust manifold, 1 for the turbo inlet and 1 that goes back to where the exhaust would come out originally, thats what is confusing to me. Why is there 2 exhaust outlets on the aftermarket manifold? Shouldn't there be only one for the turbo ontop the manifold. If not, where do I hook up my turbo exhaust outlet pipe? Any help is greatly appretiated, Thanks.

 

There is a crossover pipe from the drivers side the goes to the bottom hole.try this..

Well this turbo kit is a bit different, the turbo bolts directly on top of the driver's side exhaust manifold, and the outlet pipe runs down close to the y-pipe. I dont know, I need to get a good picture for yas.

 

Do you see any names on the turbo?



Does it look anything like the picture?

 

No. It does say RAYJAY on the turbo housing, and on the one piece for the intake it says Turbo Engineering INC. I would post some pictures, but I dont know how to.

 

That could be a little tough to find parts for.
Hey dave did you wrap your crossover pipe and what with may I ask. ??? thanks

 

I think I have all the parts I need, with the exception of 1 or 2 gaskets, its just that I dont know how to set up the exhaust.

 

Yes, I wrapped my up pipe and cross over pipe with header wrap.
Double layers of wrap, each soaked with ceramic high heat paint to keep the water out and the heat in the exhaust.
More heat in the exhaust = more boost.
The down pipe is also wrapped down past the transmission to keep the firewall and floor cooler.

Do remember, I have internal engine mods, so I want all the boost I can get.
A stock engine would not make it a mile at the boost numbers I am running before the head gaskets blew.
I see twice what you are running about every day, 15 to 20 is normal cruise boost on the interstate.

Kyle, your first step is to upload your pictures to your gallery.
You can create a new album called turbo if you want, then upload the pictures to it.

Nice truck by the way.

 

Your turbo setup would have run a crossover from the pass side manifold into the drivers side, so that both sides feed the turbo, GM style. Your downpipe will then come off of the turbo itself.

 

Hey, thanks, I'll load up some pictures for you.

 

I did some searching looking for RayJay turbos.

Found a site in Australia that still has them listed as turbos they service.

http://www.turbofast.com.au/

They may have info on a US site if you contact them, or you may find one if you seach the net a bit harder than I did.
I see a lot of pages about RayJay turbos on the Honda and BMW cars, small motors like 2.3 liter though.
And several pages related to airplanes and boats using them.

2730 hits on Google for "RayJay turbo", I looked at the first page of hits.

 

Thanks Dave, I have put some pictures and info about the turbo in my gallery.

I saw on the tubo it said RAJAY. There are many sites with them.. the company was sold and so some people are having time trying to get support and parts... http://www.gpopshop.com/rajaykits.html

but if you go to http://www.turboengineering.com/ Not sure, did they designed the turbo setup that you have using the Rajay turbo?

Nice looking truck.. btw

 

Thanks, I never noticed. I always just looked fast and never saw it was Rajay, I'll look into it.

 

RayJay turbos were popular in the 80's, but I don't think anyone makes them or parts for them anymore. Might be able to find some stuff on ebay.

You might be able to swap it out for another turbo if it's in poor shape. Take a picture of the turbine flange, exhaust flange and overall turbo and post it up.
