turbo swap...is it worth it?

[preachermanhull]

i may have access to a complete turbo set up off of a 99 7.3...would changing that out be worth the trouble on my 94.5? Would i see more boost?

If it is a L-99 and you change your up-pipes it is worth it as you have more turbo options later on down the road and will allow you to easily use 3" plenums and a L-99 spyder when you deside to intercool your truck. You wont see more boost but it will spool faster with the tighter AR ratio.

If its cheep enough,do it but get the up-pipes and the spyder and 3" plenumbs if its a L-99. If its a E-99 get the spyder and sell it elsewhere as these are hard to find

More turbo options? It gives you the choice of a 38R... nothing else.
Early or late 99? Either way, IMO, not worth it. For the work involved there will be no real performance benefit at all. Yes, you might see a little more boost quicker. But for the L99 you have to change out everything turbo related, and I do mean everything- turbo, pedestal, up pipes (possibly the drivers side manifold too), intake plenums, intake Y, then you'll also have to snag the intercooler and install that or fab up an IC delete pipe since the OBS intake Y won't work with a late 99 turbo. You may have to push the firewall back to clear the turbo too. If it's an E99, you only have to swap the turbo, pedestal, and up pipes but again, not really worth it because there isn't hardly anything to be gained.
If the parts are free, I might go ahead with it but the juice just isn't really worth the squeeze for an SD turbo swap.

Yes manifold change on drives side is required . You will need everything, up pipes, plumum turbo pedistal boots manifold hot and cold si pipes

Some people say that the drivers side MUST be changed, others say the late model up pipes will work even with the OBS manifold. Yes, the manifold is different for sure, but you might be able to get away without swapping it. YMMV but I wanted to put the info out there for the OP.

i think the manafold change may have somthing to do with the year, seems like guys with 97s dont have to change them but older ones do?? IDK, never done it.

I think the change over would definitely be worth it, you get rid of the early style pedestal, and if you're smart, you will put the late style Bellowed up-pipes on it when you change.....and while ur at it, stick a 38r ball-bearing turbo on it too....

IMO its only worth all that work is you are getting all the parts for $500 or under, and if you had a failure of your stock setup. And I mean everything including the 38r. If not put your money into a d66 and an intercooler setup.

The 38r wont support stage 2s and your still have to custom fab your IC pipes.
