Hi guys, I'm installing jnukyard kit with 14B on my 90 civic and I'm wondering about the intercooler piping size and general shape.

I've planned to use the DSM pipe leaving the turbo and connect 2" piping to it to a DSM SMIC. I know these pipes are 1.85", wil there be an issue using 2" silicon connectors?

Also, I'm planning on running the charge pipes near the front crossmember/radiator to where the intercooler will sit (resonator box spot), good or bad?

Manifold is STD with BMC adapter plate

Pics/Ideas/Bitching welcome

Well it sounds like a workable plan, but no, the silicone couplers will not make the conversion.. too much risk of them leaking. I would say try and figure something else out.

Maybe you could always add some fiberglass to the piping and raise the diameter up that way?

Would I be better off cutting the flange off the compressor and IC and weld 2" pipes on them?
I'll probably need to modify the endtanks and I don't think the compressor housing exit is close to 2"

I guess fiberglass could work well, the differenc is "only" 5mm so it wouldn't require lots and, I assume, it does stick to bare metal quite well.

Keep the ideas coming, I need to sort this out before I go insane.

Damn, cutting off flanges and ----.. this is sounding complicated.

First off, let's examine the metals you are working with. I know the IC is aluminum, so you will need to modify it with some skill.. a push/pull welder or TIG would work the best, but MIG is possible. You might think of just getting a different one or doing my previous modifications idea.

I'll get into this more with you later tonight, I have some things to do first. I'll let you know your possible options in my opinion.

Silicon will work fine just make sure you use some clamps on it so it doesnt burst off. And if you dont like it later you can do all that crazy welding and ----.

Yeah, I didn't say the aluminum was going to be easy, but there are ways to properly weld it. As for welding the turbo, I would suggest something else to add some meat to the pipe.

My thought is to get some of those torch rods used for filler and miner welding.. I've used them before to fill a hole in the exhaust manifold on the truck (------- air pumps and environmental friendly ---- went out the door first thing on that bitch). You can just add metal to the turbo outlet, melt them with low heat, is a good filler. You can then grind it down to spec. Fiberglass would be your answer on the IC.. I wouldn't suggest fiberglass in contact with high heat.

If it's only like 5mm (i don't feel like looking up the metric conversions) then that would only be 2.5mm of filler added all the way around, very do-able. Just some suggestions for you, let me know if you think any of this will work for you.

Another possibility could be to use the same size piping then the IC and little pipe leaving the turbo ~1.75"

I've seen DSM with 300hp with that size tubing
The only problem is that the TB is ~2.25" in diameter

Would this be a feasible choice?

I'm leaning toward the fiberglass idea but I'm keeping my options open

quadnie

I really haven't exposed fiberglass to high temps for long periods of time. Anyone want to jump in on this one? I feel like just molding some around one of my downpipes and watch to see what the ---- will do.
