I need some help in figuring out an aftermarket turbo. I deal directly with BD here in Canada and was on the phone with them today regarding there BD Turbo systems. They make one for the 94+ trucks but don't recomend it for the older 12v because they havent tested it. The specs are 4" outlet 12cm w/g turbine and a 64mm comp wheel. This is a large wheel and I will need some fuel to spin it but I have a Bully dog fuel pin and BD 40hp injectors coming. What things are different between the older/newer trucks? Are there other pieces I will need to buy? I have a banks intercooler coming so I'm not worried about that. Also i realize i will need a piston pump probably soon as well.

 

You could also call Piers Diesel - www.piersdiesel.com. They are also in BC.
Your '89 has the baby-H1C which only has a 3" air inlet if I'm not mistaken. The 91.5-93 intercooled trucks have a 4" inlet. Also, the non-I/C trucks have a 2" outlet to the intake, but none of this makes any difference with the aftermarket turbo and intercooler.

 

I don't think you'll have enough fuel to run that turbo. With the fuel you'll have you'd be better served with a hybrid.

 

If I go to the DDP 75hp Injectors is it possible I will have enough fuel. I just dont think the DDP injectors are much bigger then the BD 40hp injectors. I talked to BD and their 40hp non i/c are the same as their 60hp intercooled injectors. As far as DDP go their 75hp is compared to the i/c injectors as well so that is only 15hp more then the BD's. How else can I bump the fuel enough to supply this thing.

your link didn't work!!!!

 

guess I'll have to go to the DDP stage 3 or 4 injectors and just bite the bullet Anyone got a used set they just cant stand anymore

 

It would take a lot of fuel to spin the 64 wheeled turbo.

 

Just got off the phone with the turbo tech guys at BD this morning. It turn out the salesman was a little confused as the BD Super B turbo I was looking at is actually a 12cm w/g turbine w/a 56mm extended tip comp wheel. Looks like this thing will actually spool awsome with some fuel upgrades without having to break the bank on monster injectors.

 

Yeah, that ought to work out very well.
