Sorry ahead of time for the barrage of questions, but I tried putting them all together so I won't have to ask later. So I'm installing a single turbo kit myself and most everything is in, but I can't figure out how to connect the oil and coolant lines to the turbo. The kit is a used eternal motorsport kit. There's no instruction manual that could be found so I'm using the turbonetics instructions as a kind of reference since it's pretty similar, but it's much to vague about hooking up the lines.

Here's the turbo installed in my car

I think the connections are (from left to right with the blue tape over them) Coolant retun, oil feed, coolant feed. And on the bottom of the turbo is the oil return. If that's not right can someone correct me.

Here's the kit installed on another members car


The oil return line is pretty straightforward and I'm pretty sure feed line just needs the tee fitting installed near the oil pressure sensor.

The coolant lines are confusing me as I don't know where to splice into. The turbonetics kit instruction doesn't really look like the Z/G so where exactly can I cut into the coolant line to run to the turbo?

Apart from the turbo I think this is one of the fuel lines


Is this another fuel line? And if it is, would it connect to the fmu? I have a JWT FMU that is connected to the fuel pump in the tank.


And last question. Is this the an oil temp sensor?


Thanks for any help

 

You are correct on the pluming. As for which coolant line People usually attach it to the bypass hose that goes from the passenger side pipe in front of the engine and attaches to the front of the thermostat. Turbo goes in between those 2 connections.

As for those "fuel lines" I have no idea. Looks like a weird system that I would never trust. Put a walbro in the tank and get a simple boost reference return system like cjm motorsports stage 0. It's worth the money over some of the jimmy rigged fuel systems out there with these turbo kits.

 

Looks like vacuum lines to me bud.

 

Most top mount ST kits , PL and MTM :

a) remove the "throttle body" warmer line"
b) connect one port found on the rear water log to one Turbo port.
c) connect second port found on the drver side water hard pipe to the other Turbo port.

Not much water flow is needed. Just enough standing water to wick heat from the cartridge bearings when the engine is shut off.

 

Never heard of a turbo kit using fuel lines. Thinking of it, I've never even seen that kit before.

The PowerLab instructions would help out.

I put the walbro in the tank. Just wasn't sure what these other lines might be. Kind of took a guess. I'm learning as I go through the installation so I'm probably wrong about those lines being fuel.

Thanks for the coolant line clarification

 

That's what I was thinking after I looked at some of the old pictures. Maybe for the boost control solenoid?

I'm not putting in a boost controller yet.

 

Yea it's a custom designed kit from a shop in North Carolina. Unfortunately they're not around anymore so I'm having to wing most of the install. But I'm learning a lot

Any idea where I could get my hands on the Powerlab instructions? Couldn't find them through the Powerlab site or through google.

I did find jeffie7's post though

your fuel kit is returnless id imagie so drilling out a walbro and instlling it into the tank is all thats needed for now. take a peek into the greddy instructions on how they set up the oil feed lines as it tees off where the sensor goes on the bottom passnger fron side of the block. you want your oil return to literally drop straight down into the pan. as for the coolant lines, use the above info as i cant recall on my previous setups. id invest in a turbo timer and secondary oil filter as well.

 

Those black hoses look like vacuum lines and a vacuum distribution block.. Also a pressure sensor in that last pick, prolly from the boost gauge..

Plumbing looks correct to me and like said earlier use the line that feeds the throttle body and u should be good...

Good luck!

 

Thanks for help guys. The turbo is all hooked up and ready to go. Put some high quality parker pushrock lines on it so I'm hoping it's all hooked up right. Heres where I plugged the hoses in.


I'm a little confused about the fuel pump assembly still. Not the fuel pump exactly but the FMU that is connected to the pump assembly. Its this thing right here.

The line that comes off the FMU and runs up to the engine bay. What does it connect to? And do I even need the FMU? Seems like this was designed for a twin turbo setup, and I'm only running single.

Would there be any benefits of keeping it in and hooking it up on a single setup?

 

I've never even seen that kit before.

 

Yea as far as I know its only one of two complete kits that were designed. So it can pretty much be called a custom kit. Seems like it should work though. If it doesn't I'll take it as a learning experience and try to build another motor up for some REAL power

 

The signal line hooks up to any vacuum "Always been a fan of going off the compressor housing myself, but it's your call". This allows the RRFPC to function and give you that much needed fuel pressure while in boost but go down while in vac. Just be careful with routing the signal line.

 

Thanks RDZ. I ended up hooking it up to the nipple on the front of the manifold. Seemed like a good place

 

I would put heat wrap on these lines that are dangerously close to the extremely hot turbine.

The electrical wires and that rubber hose will not like the heat.

From your other pics it looks like the plastic cover on the a/c line should be removed and replaced with heat shield as well.

Just an FYI.

 

top mount kits need turbo blankets.

 

what about turbo quilts? or a throw?

 

Yea I have a turbo blanket. Looking at how much heat the turbo made from a few videos, it seemed like a worthwhile investment
