7.3 IDI Mods

Turbo for idi
I think it is an HX35. I have a bigger turbo for my Detroit 8V92, but I have the whole 8V92 engine to bolt that big Garrett too.

I been seeing common boost pressures on Silver 92s 22-26 psi at full throttle uphill

Going to guess its way too big unless it has twins like the E9 and a couple other big monsters. Any measurements of the wheels or housings? You can get a used 7.3 powerstroke turbo for like 150 bucks on craigslist. Has some goofy flanges and fittings, but you can make an exhaust brake out of the EPBV. Almost went with one myself for that reason.

Turbo for idi
Im not going with the big Detroit turbo. I don't see the need. This truck has had some pump and injector mods. I'm going to use the 6bt turbo. I don't need stupid power. After all, its a work truck.

From the top;
- cold air intake. Make your own if you cannot buy and some 4" hot air pipe elbows and pipe will work wonders when extended to front on engine bay. Should cost about $50.00
- have your local exhaust dealer fit a twin 3" system and straight thru muffers from stock manifiolds. Should cost about $300
- add an electric fuel pump and raycor filter to fuel line system so you have the standard mechanical pump plus an electric pump delivering adequate fuel supply to injector pump. Cost about $50
- New paper air filter. Should cost about $65
- remove and close off fuel return line from standard fuel filter for better starting. A plug can be purchased to fit fuel line return orifice in filter housing. Should cost about $2.50
- Now you will flow air through the engine and match that increased flow to a adequate fuel supply from the dual pumps.
- Use a cetane fuel booster and injector pump lubricator like Powerkleen at 1 ozs per gallon
- Turn up the injector pump screw by about an eight of a turn and you will have the best performance that you can get from the lowest dollar.
- These engines were strangled for air when they were released and just by providing adequate air flow and fuel you will gain about 20 to 25 hp and if the engine is in reasonable condition you should be able to use that increase in power..
when you say dual 3” are you day run true dual exhaust from the header?

When you said to add an electronic fuel pump and racor filter in addition to the mechanical pump, does the new pump and filter get installed before or after the mechanical fuel pump, and before or after the existing fuel filter?

When you say to disconnect the return fuel line from the filter then plug the hole in the filter housing, where do you run the line that was going into the filter? And..

You should start your own thread and ask these questions.
You will get current answers for people that are active on the Forum.
The info in the old thread is good, but it is like going to a Cemetary and asking for advice
from people long gone.
Reading through the post, do not run a mechanical pump with an electric pump.
One or the other.
The trucks did come with a cold air intake from the factory. Follow the plastic tube from
the air filter housing.
If you want to gain more HP, add a Turbo, IP that puts out more fuel as well as matched
Injectors and a few other goodies.
