| If i dont want to put heating in my van at first can i just connect together the two heater pipes sticking out the back of the Ej20 engine? I may in the future wish to fit a heating system. |

Yes. The best/easy way:
2x 15mm 90° solder ring connectors
3 short 15mm copper pipes
2 x 15mm olives
4 x Jubilee clips
2 short lengths of hose
Solder up into a U bend, solder olives on ends to hold rubber pipes
If you just use a rubber tube it'll kink up

Join them together by whatever means - as long as you don't block them off instead!

Sorry to thread crash but on the same subject.
On my ej20t it had two inlet/oulets on the stat housing ive got one connected to the bottom of the expansion tank, but couldnt figure where the other went and just blocked it off....
Is this ok or am i going to run into problems?
cheers..

The turbo engines have one 12mm pipe which goes to the standard Subaru header (the pipe bolted to the inlet manifold) via a steel pipe which follows the coolant manifold across the block. If I remember right this is the upper one. The other is the same as the non turbo's and sticks out near the starter, for the heater. Off the top of my head I can't remember where the oil / water heat exchanger plumbs in to - I think it uses a third small pipe fitting on the water pump.
The turbo's generally have more bypass flow contained within the engine (the oil / water heat exchanger, the throttle body heater, and the turbo if it's water cooled, as opposed to just the throttle body heater on the n/a's), so this may be enough to keep the thermostat warm when the heater flow is blocked. I have never tried it though, so you'd have to experiment if you really want to block some of the pipes.

Do you mean literally on the Stat housing down by the water pump or the do you mean the metal pipe that comes up from the stat housing and would eventually connect to the heater?
My Subaru stat housing has three oulet down at the Thermostat ? one for the oil cooler, the other is for the heater return (similar to N/A engines) and the last I can't rmember. Unless you have the wrong coolant pump fitted as there is a difference between the pumps with the dualcam and quad cam engines. Dual stat housing has two outlet and the quad has three.
If however you are talking about on top of the engine the metal heater return pipe which flows to the thermostat housing then there are only two connections, one for the heater return and the other is the return from the Subaru header tank ( I've connected this to the Turbo coolant outlet)
Either way so long as the your confident that the coolant is flowing the correct way and that the components are recieving coolant then all should be good.

Not just yet dude  ....
Two small plates need welding and id managed to crush the hard line of the rear brakes putting the engine and gearbox in, so brake fail... and the major headache, bottom ball joint needs replacing...
Gets to 90 pretty bloody quick though but i need another silencer in the system, bit too much for these old ears to take 
Turned a few heads at the MOT station
