turbo help
okay wasnt really planning on turbocharging the old 6.9 in my 87 but a couple of you guys deffinately got me thinking other wise now. i cant help but feel like ill be opening up pandoras box tearing into this thing... anyhow i dont know what new aftermarket turbo kits are going for but im fairly sure i cant afford it so anyone on hear know a cheaper way i can do it maybe finding the right used parts??? im pretty satisfied with the old 6.9 as it is with only some air filter mods (didnt have soup bowl but had tiny air inlet i cut out to match up closer to the intake opening). everything else is bone stock. im just looking for a little more out of her. you guys think 3 inch exhaust and i guess you can turn up the injection pump or so ive heard, would help me out at all???

turbo is the best bet to get more out of it.with a diesel more air in and more air out makes a happy diesel engine.you can turn the pump up but are you getting any black smoke now?if so you have all the fuel you can handle.and as a good preventative measure have a pyro in before you turn up the pump.also your fuel system may need attention your ip and injectors may need replacing and that will restore a lot of lost power as well.another way you can go is lower gearing which will kill your mileage too.but all in all you cant beat a turbo

no i havent noticed any black smoke... so would i be okay to turn the pump up a little without killing milleage?? also it seems to run good so is there a way i could first check the pump and injectors?? maybe they have already been replaced or maybe just still good................. ??

As stated, Turbo is the best thing one can do to a Diesel, it's not cheap.
As stated, Turning up the IP without a pyrometer is dangerous.
Free flowing exhaust can't hurt.
Turn the IP up till you just see black smoke under load (ie: pulling a long hill)
Then turn it back a little until there is no black smoke ... black smoke is unburnt fuel wasted! A little puff when accelerating is acceptable.
-Enjoy
