2nd gen IC into '90 non IC Q's

[theoldmanW350]

Hello all. I just bought a '96 IC for my stock '90 non IC. I have the hot side pipe/boots, turbo elbow and the intake horn. Gotta get the cold side pipe. Do I have to purchase an IC H1C housing for the turbo elbow to fit up? Would using an 90* elbow from my H1C to the inlet pipe be sufficient? Also I've come across the term "clock your turbo". Is moving the turbo out of stock position "clocking" a turbo? I obviously gotta move my comp.housing to make this mod. happen. Is it a simple unbolt, rotate, bolt backup? Thanks guys.

Forgot. Any special precautions before I remove the AC condenser lines from the compressor? Also just went out to look closer for the intake fit up and looks like i'll have to cut my throttle bracket. Any one out there gone a different route with a homemade intake horn? I'm familiar with siliconeintakes.com and seems I could fab something up from there. Thanks again.

Caleb will chime in soon since he has done this on his.

Get yourself a IC throttle bracket. There is some trimming involved, but much less than if you run the original. I had to trim my battery tray a bit too. I used everything off a 2nd gen, from the turbo outlet elbow to the intake horn. As for clocking the turbo, loosen the v band clamp, and rotate the housing. I had a built H1C left over, so I pulled the stocker. You should be able to find a reducer and a 90 degree bend to make your current turbo work with it all.

Gotta get the cold side pipe.

The cold pipe is straight with beads on the end. If you don't care how things look under the hood and won't go high on boost, just get some exhaust pipe.

Do I have to purchase an IC H1C housing for the turbo elbow to fit up? Would using an 90* elbow from my H1C to the inlet pipe be sufficient?

If you change to the later housing, you have to get the corresponding compressor wheel. If you want to use that elbow, you may as well find an HX35 or get an IC 60mm upgrade. I originally used a 90* reducing elbow from Frozenboost with my H1C. 3" to 2" 90* reducer I think. Measurements are in the thread above.

Appreciate the replies so far. The v band clamp! Of course. I saw right past it. Glad it won't be a pain. I'll grab a 90* reducer for the hot side from the turbo. I'm thinking of getting a flange fab'd then buying a 180* exhaust pipe piece for a homemade intake horn. Then of course a straight pipe for the cold side. Anyway the project is a bit slow going. I do have a line on an HX35 from the same guy I bought the IC from. $250? A 60mm compressor/wheel upgrade is almost the same price. My current goal is to make a capable tow rig. I hear the HX35 gets hot when towing (goal: bed of hardwood plus a cord of hardwood in a trailer) and can snap its shaft when letting off the gas too quickly. I've read the hybrid HX35/40 is a sure bet. cmann250m I appreciate your write up. Thanks for the reply.

I have the HX35 now. I really like it with 3.07 gears and an auto, which is what you have if I remember correctly.

The HX35 may get hot if you're throwing a lot of fuel at it because it has a quick-spooling 12cm housing. Reliability shouldn't be a concern. The HX35 is tough.
If you get a 60mm upgrade, you'll have more air flow and have more exhaust flow with the stock 18cm housing when compared to the 12cm housing of the HX35.

It depends on if you want quick spooling or excellent flow. Both of those are also determinants of how much fuel it has.

Thanks cmann250. I went to my local scrap and salvage today to grab a square of metal to fab up some lower mount brackets for the IC and found some 3" aluminum tube for the IC pipes. At a buck a foot I couldn't pass it up. All the tube I've come across on the net is T6061 aluminum. This pipe is not T6061. This pipe has been sittin out in the elements so has some surface corrosion (a whitish powdery corrosion). If I scour it clean outside and inside would you (or anyone readin this) use it? The quality of the aluminum may be such that it will continue to produce a powdery surface corrosion and I don't want that burnin up inside the engine. Not sure if this is even a concern. I just wanna get this project done.

[cmann250]

In my experience, I've always had a film of oil through the intake tract from running a high mileage turbo. It's just enough that the inside of the pipes do not feel dry.

I don't see corrosion being an issue if your truck is doing the same thing. Maybe try it for a week or two and see if the corrosion comes back.

[theoldmanW350]

I've had this project completed for a week or so. Finally! Still want to fab up a DIY boost leak detector but for now the old man drives just fine. I thought the new IC would quiet the engine a bit but no dice. No matter. The pyro is measuring about 100* coooler and i figure a compressor upgrade will lower temps a bit more(?) I was gonna list my own observations for this project but anyone out there considering the same can ask away. Cheers.

Post up some pics if you can. I did the psic on my 90 along with an alum radiator. Did the intake plate flip, cut/modded/welded throttle bracket, 24v air horn. Turned out good, but had I been aware of the 2ndgen setup I would thrown the ic and rad in there. Next time.

I was going to take pics during this install but ditched that idea. There are already some good write ups here and on other forums. I got the measurements for where to cut the charge pipe holes off DTR from member flashgordon (actually his whole write-up is helpful). Actually I will take some pics though the truck is all back together.
