I'm trying to upgrade my 1994 F-250 IDI from the stock turbo to the Turbonetics TS04 but I'm running into a couple of obstacles and I was wondering if anyone had done this before and could offer some advice. The main problem that I'm having right now is because of the larger compressor housing diameter of the TS04 it is hitting my injector lines and intake. I'm thinking about getting a spacer built for the exhaust inlet and oil return bracket but before I go to a machine shop I wanted to know if anyone knows of a kit that comes with these pieces or if someone has a better idea. Thanks for the help.

i think your trying to achieve more boost correct?

 

Yeah I'm trying to get a little more boost and decrease turbo lag.

 

well i got some bad news. these engines without some serious SERIOUS mods wont handle more than about 12 lbs of boost then you'll start blowing gaskets ect. a built 6.9 can get into the 18 lb neighborhood and dave S made it to 25 but i believe still has odds and ends failures. the advantage of a 6.9 is the ability to use head studs. the 7.3 has no head stud kit. and the cylinder walls are thin compared to the 6.9

the wastegate on the factory turbo can be adjusted to make the 10-12 lbs the 7.3 can handle i believe.

for the 6.9 to get more boost a banks kit, ATS, or hypermax kit will make all you need and fit correctly.

others will hopefully chime in and correct me if needed or expand on this. i just recently aquired a factory turbo engine that im going to transfer the turbo onto mine. and will if i can get some instruction turn the wastegate up. also turbo spool times are adjusted with fuel settings i think.... i read something recently about the torque screw and fuel screw adjusted in sync can reduce turbo lag with the factory setup or the 3 big kits made for these engines.

 

I've been told by several engine builders and specialist that the 7.3 IDI will actually handle closer to 15-17 lbs of boost without any problems. I already own this turbo. It's not a matter of whether or not it will work I just wanted second opinions on my idea of how to make it work.

 

Boosting over 15psi is a risk I wouldn't take, unless you have heads studs or enjoy pulling the heads. The safe max on the stock head bolts is 15 psi. Just out of curiosity, what are you boosting now? If you have the stock DP - the turbine housing will have back pressure to fight with, thus the wheel spinning slower and thus the pressure housing getting lower boost. Un-restricted cold air to the compression hosing and a un-restricted DP will increase boost.

 

The stock turbo that came with the truck had a bad turbine and since Ford was too cheap to include a boost pressure gauge in the truck I don't know what kind of boost it was pushing. I got a new TS04 for the same price as a stock replacement and figured I would go with that instead. I'm not looking to run tons of boost (right around 15 psi)or get ridiculous HP numbers, I'm hoping for circa 300hp. I'm just trying to get a truck that will tow through the Smokies without making me drive in the slow lane with the flashers on I am upgrading the stock exhaust right now with the turbo and I'm upgrading the stock intake as well. I already have stage 1 injectors from DPS Performance and their turbo calibrated pump.

 

if you could have those injectors pop tested that would be kinda interesting to see if there really is a difference between there "stage 1" and regular BB code injectors.

also the pump is the same pump between NA engines and Turbo engines (IDI) the difference there is the fuel screw is turned up. and possibly there may have been some adjustment to the torque screw

 

Do you have a powerstroke??? If you do, your engine says DI on the top. I dunno of any stage 1 injectors for IDI's?

 

if you want less lag and more boost with your stock turbo, just ceramic spray the manifolds, cross pipe and up pipes then wrap them with header wrap thats been soaked in the ceramic spray. also larger exhaust and better flowing intake will help

 

there are. heard the company that makes them sucks, terrible spray pattern and not very reliable

 

I think he has a stroker oreo. Anyway, it would probably still help whether its a PSD or IDI.

Posted at same time, he may or may not, he just has to respond.

 

well, seeing as how he said the turbo is hitting the injector lines and intake its safe to assume its a idi.

 

Just checked out DPS performance, your right, I guess he does have a IDI. Not that familiar with the stock turbo I guess.
