installing a turbo to non turbo c223 engine

Postby bizz80 » Sat Oct 28, 2017 5:02 am

i have an 85 trooper with c223 engine install. i was thinking of installing an ihi rhf5 turbo on it. i've never install an turbo to a non turbo engine before. can i just install the turbo without any modification to the engine? from the spec, c223 and c223T have the same compression ratio.

Many people here have done it. I have never done it... Nor am I an expert. But there are several writeups here as to how people have done it. I think most people just turn up the fuel screw is my understanding.

Diesels are "easy" to turbo, as far as compared to a N/A gas motor.
Especially mechanically injected diesels, as pretty much all factory N/A diesel bits can work well with a correctly sized turbo(both turbine and compressor wheels and housings).

Results vary with realistic goals, factory bits availability, money, skill, time, design of entire system, quality of aftermarket parts used, money, skill, time, determination, personal research invested, and money, skill, time.
Unskilled, uneducated, inexperienced, tools/facilities lacking, and faint of heart, be warned:
All vehicles are hunks of crap. Designed by individuals, the majority of which, have never turned a wrench.
Which one do you want to fall in love with?

Yes it can be done. I installed a Garrett gt1749 on my c223 5k miles ago. It's amazing how different the engine feels. How much boost are you planning to run?

so, basically, you can just install a turbo on a NA diesel engine wihout any major modification?
the ihi turbo is the only part i have lying around, and doing any major internal and injector bit on c223 engine just not worth it.
thx

The na pop off pressure works with the turbo perfectly. I didn't raise my pop off pressure nor modified my engine internals. I installed the turbo, turned the fuel load screw about 1/4 of a turn and that was it. Finding a good location was the harder part due to space.

i'm not planning on adding too much boost. to honest, i'm still searching on how much boost the ihi rhf4 turbo makes.

The connecting rods aren't very capable of holding the extra pressure.. they had a long run with converting these to turbo..

But interestingly the rod problems were only with the turbo engines from the factory. There have been many others who have turbod their na motors and havent had any problems.
2 86 Trooper II diesels, one 4 door the other 2, both projects.
86 Jeep Cherokee Pioneer with factory 2.1L turbo diesel.
05 Jeep Liberty Limited with 2.8L diesel (totaled)
06 Chevy Silverado with duramax
2014 Jeep Grand Cherokee ecodiesel

Adding a turbo to an NA c223 isn't all that risky if planted into a 2wd, from what I've heard from Jerry Lemond. One of the weak links in the turbo c223 in a trooper or 4x4 truck was over-reving while in lowrange. They'd throw a rod.
Leaky turbo oil seal leaking into the intake was one other weak links for the turbo engine...Again, over-reving from a runaway engine (running off its own oil) killing the rods

Actually the na rods are beefier than the turbo first gen rods, they look a lot like the 2nd gen. The problem was over revving and the governor not being able to react fast enough. Just keeping the red line below 4000rpm will give it a decent live after adding the turbo.
