Hi! It's been a while since i saw you on the board!

As you know i have been working on replicating your intercooler install, but with my own twist. Progress is good, engine is done and on its way in, and ic is in place. I have run into a little issue, the comp outlet is very close to the oil return line/nut, so close that i can't fit a Silicone hose in there. It only works if my comp outlet is pointing straight down more or less, but then im not sure it will cleare the steering rack.

Any ideas on this? Did it work better for you maybe since the coolant hose is thinner than Silicone hoses?


Hey man good to hear from ya.. I scan the board from time to time still and I'll get back to it some day..

Anyway about the oil cooler lines..
I think what I did was something like loosten them, and then rotate them to where they pointed down toward the ground, then tightened them back up, and then bent their angles slightly up toward the turbo block mount, then loosen them again, rotate them up high to clear the turbo outlet..

I also ground down that nub on the block with great success..
Also I ground one of the steering rack mount hole tube things down a half inch or so, made the bolt thread down further, to where the turbo outlet would clear the block and steering rack better..

I'm having dinner at my moms right now but if you want to give me a specific thread to drop some pics in when I get home I'll go out there, snap some pics, and post them to your thread for reference..

Ya I guess this will be that thread..

Yeah I basically just bent them out of the way..
To me they are basically like big break lines, they can be massaged a bit..

The oil cooler.. I straightened out the bracket on it and bolted that on one of the washer bottle bolts I believe, and the other side to my radiator spacer frame..

Me looking at these pics now I remember that these lines aren't tight on their banjo side right now so they are resting on the comp housing..
Lift the lines up before tightening the banjo bolts and that holds em up a little higher..

Also you see the blue turbo tag.. If you take a close look at it you can see where I ground that corner of it down where it sticks out there to give the lines more space..
Check out the cool spiderwebs too

Thanks for the answer,, I have yet to hassle with the oil cooler lines, that will be when the engine is in place since i need to modify them for my new setrab cooler.

My first hurdle is the turbo oil return line nut, I hope the picture explains it better.

Ok I got ya..

I don't think I ever had a problem with that line with respect to the compressor discharge piping..

I did have a problem with that line rubbing my Xmember but It wa an eaxy fix, guess I didn't quite put it back together on the same angle or something..

I guess I am going to have to go take another look at mine but remember your compressor is a size bigger than mine, which I really hope does not screw up the whole design..

I bet you can tweak that big nut around enough to get the flat side facing your discharge nipple, gain you a couple mm..
Also I might try loostening the 2 bolts that hold that drain manifold thing to the turbo bearing housing and see if you cant get it to turn a bit via some slop in the mounting stud holes.. If not, maybe hog those 2 mount holes in the drain manifold thing out a bit toward the direction you want to turn a little and get it to move enough that way to get it out of your way..


In your picture that nub on the block just behind that big nut is the one I ground the front half off of to better clear the discharge hose so the hhose pretty much runs 1/4" deep into that nub and down the block..
To give you an idea of where its really pointed..

Oh yeah..
Or maybe you could use one of these to make it work.. If all else fails..

I love your turbo upgrade. Where did you buy the billet wheel ?

Fasteddie, thanks for the thoughts, the compressor side isnt fixed in position until the engine is dropped in. Maybe we will have to continue the discussion then and see if I can get things working. I reaally look forward getting this going. Will se if i can get that nut better positioned before the drop in.


The comp wheel is from slturbo.com, a real turbo geek who knows all kkk part numbers by heart. I think its kts turbo billet who made it. I think he still have some of them left. He have a high speed balancing machine aswell, which is a minimum requirement from my side.

Cooling package with mega fat intercooler is soon in place, i hope it will work when everything is there. Might paint everything black when I'm finished for the stealth look.

Excuse me for the mega crap quality picture.

Engine is now in place, which means that the second stage of work take place, with all the piping, oil cooler lines etc need to be solved. I might rethink the routing of the boost pipes, ill come back with some pictures if it seems to work.

Just went through your whole thread again and man your car is going to be awesome..
Your rad and IC are massive, I hope you can find a sleek way to route your intake plumbing and it looks like you can..
Looking back I see that you have that updated turbo oil drain with the separator that also goes to the top of the head.. Mine doesn't have that, just the hose from the turbo oil drain to the oilpan..
I think this is what is making the difference in your compressor outlet clearance..

I'm curious to see what you will come up with for a recirculating blow off valve and the associated plumbing from the ait meter to the compressor inlet.. I would like to do mine differently and put the BOV down under rather than up top front and center, hide it..

Leadfoot gave me a couple oil cooler AN fittings that fit the oil filter adaptor on the block welded to AN fittings but I have not used them..

I also want to eventually figure out how to get the undertray skid pan thing on my car over all the piping, maybe you will figure this out too..

I think I am going to have more time to work on mine now and have a real itch to hear it run so I might fire it up soon and go back from there to connect all the loose ends..
