I'm going to do something really interesting. I'm going to put a turbo on my NA without swapping engines. All i need to so is find a place to splice oil lines and cooling lines. ANy ideas? I figured the upper and lower radiator hoses for cooling, and i was thinking maybe splicing into the oil filter for lubrication, and then going back into the oil pan. Has anyone done this before, or have any other ideas as to where i should get oil from? Should i go from the oil filter and then back into the other side of the oil filter for the return from the turbo? Any ideas would be great, and yes i know, it's so much easier to replace the motor...i did that, this is a temporary setup while my t2 motor is getting rebuilt. aObviously, i am desperate for my power! Again, thanks,

can a person turbo the higher comp. rotors???

hmmm.. interesting

Yes, I have. So has Aaron.

Alright, for oil feed you have a number of options:

A) tap the oil filter pedistal
B) Tap the oil cooler/the banjo bolts on the lines
C) splice in on the oil pressure sending unit (hard to match thread for this to work)

I chose A. As for oil return, you can simply drill/tap the front cover and install a barb and just use hose to drain (make sure it's DOWNHILL, as the return is gravity feed!) Other than that, it's all pretty simple.

Just to further critique what you said. Here are some idea's.

Don't tap the radiator hoses, leave them alone. Use the hose coming off the back of the waterpump that snakes around throught the BAC and into the TB (if you haven't done the TB mod), and goes back in under the engine. Just place the turbo in that route and you'll be perfect.
I assume you know you will have to weld up your own exhaust manifold, and downpipe (or have an exhaust shop make that part), plus the custom intercooler setup, obviously fuel/injectors/s-afc to control it (or possibly even the turbo ECU/afm/boost sensor/etc). It's a pretty easy thing to do if you're good with fabbing up your own parts/etc, otherwise I'd just leave it be until your other engine is finished.

how exactly did you tap the oil filter pedistal? And i was thinking that i would just use the t2 manifolds; that way i could use the sensors and stuff, and also the t2 ecu. You say just drill a hole in the pan, and stick a hose in there with some kind of rtv sealant around it? Tweakit makes an adaptor plate for a 6-port to 4-port. I was going to use it in conjuction with the t2 manifolds. what do you think?

Don't use the oil pan, it's too low. Use the front cover. Or just use a tII front cover (like I did) Let me find some pics. Just drill the hole, tap it, and install a hose barb (found at most any home depot) and then you can just clamp a hose to it.

Here's a pic of my oil feed spot:

extreme_rotary

yeah, pictures would be nice; i'm not familiar with how to tap the line into a hole with a hose barb, i don't even know what a hose barb is. if i don't use the front cover off my t2, you're saying to drill a hole and use a hose barb, or did you mean to use that for the oil filter platform?

extreme_rotary

so i'm drilling a hole, and screwing a hose barb into that hole, then i attach another hose to the other end of the barb? Is fuel line hose okay?

Well, here's what you do if you use the N/A cover. You either A) custom make an oil return line for the turbo, or b) hack the end off the oil return pipe and then find a hose that fits over it, then take this hose to home depot, go back to the pipe fitting section and you should find some hose barbs (one end is threaded like a bolt, the other end has a nipple for a hose), find one that will fit the hose you have. Then just drill a hole and tap it in the front cover, install the barb (just thread it in and tighten it (with some sealant of course) As for the feed, it's a little bit trickier. I used a 1/8th male/male coupler, drilled and tapped the hole on the oil pedistal, installed the coupler, then i got a 1/8th to 1/4th (all sizes are NPT) 90 degree elbow, then I got a 1/4th npt barb to thread in the elbow, this allowed me to point the hose forward (so I could run it up around the engine easier). I then hacked the metal bolt end off the oil feed pipe on the top of the turbo, and put a compression fitting on it (5/16th), which allowed me to add another 1/4th barb. This way I could install/swap hoses easily, and it looks nice and doesn't leak at all. If you have any questions, feel free to ask.

i see you have some of the connectos on the vacuum spider disconnected, can i just remove all that stuff and leave the oil lines? Or do i need the vauum lines for something? What is that vauum line in the picture that is spliced around the oil filter?

extreme_rotary

that's some interesting stuff, so if i go to home depot and ask for those connectors and stuff, with all the sizes you specified, i should be able to tap into it just as you did? Geez, i hope they know what i need... What is all required to swap out the front covers besides a new gasket?

The front cover swap isn't for the weak of heart, so I'd try to avoid that if at all possible. Yes, they should know exactly what you're talking about. It'll be a 1/8 male junection, a 1/8th -> 1/4th 90 degree elbow, and a 1/4th hose barb (the hose barbs I actually found at NAPA near the air hose supplies, my home depot was out of them) I also got the compression fitting for the metal feed bar (I removed it and brought it in to napa), and the found a 5/16th compression fitting with a 1/4th NPT female on one end, and I just threaded the barb into that. I wish i took pictures of everything before hand so you could get an idea. Let me google around a bit.

extreme_rotary

what's a compression fitting do? You said that you hooked the compression fitting onto the oil feed pipe where you cut off the bolt part. Does a compression fitting screw inside the line? or does it somehow attach itself to the outside of the line?

extreme_rotary

thanks a lot for your help, i'm going to get on this stuff tomorrow. if you happen to find any pictures, and you have a free minute, post 'em for me so i can figure out what it is that i need. Or if you have any other pictures of your own setup, they would be an excellent reference.
Thanks,

Alright, here we go:

Hose barb:


Elbow: (You'll want a 1/8th female to 1/4th female)


And a junction:


Note that none of these are actual part numbers/etc you'll need, just for reference as to what they look like. A compression fitting is a neat little device that has a cap on one end with the hose size drilled in the center of it, it'll attaches to a threaded bolt which the oil feed pipe will rest inside, and what it does, it has a metal rounded ring you place over the pipe, so first you put the cap on, then the compression ring, and then you attach the other end and screw the cap on, as you tighten it it squeezes that ring, and since it has nowhere to go, it presses against the pipe and forms a seal. I know, bad description. Let me find a diagram for that now.

Something like this:

I got a good site that at the bottom diagrams how to attach a compression fitting...check it out...

Here is how I made my Coolant inlet line.

I trimmed the BAC coolant line on the back of the waterpump so it was a straight line.

I then got some High temp silicone wrapped coolant hose(GOOD ****!).

I cut a piece about 2 inches long.
Clamped it onto the end.

I then got a barbed brass fitting and made a 90 degree turn towards the turbo.

Then get about 1 to 1 1/2 feet of the hose and hook it right up to the inlet line on the turbo.

Bam! You just made a coolant inlet line.

You can kind of see it in this pic on the top right.
It's silver and light blue(lol I know that helps )



Here is my oil return line. I'm TII engine but you can easily just route this to the oil pan instead. MAKE SURE IT IS NICE AND OPEN AND DOWNHILL! IT'S GRAVITY FEED!

Here are pics of my oil system for the turbo.

SS and AN stuff is easy and works damn well.
Just modify the lengths and you'll have your own set.


I think APT Turbo has the adapters which make this stuiff bolt on instead of having to tap turbos.



The part numbers for the oil inlet. You'll need custom length most likely
