begi sells a complete reroute kit here: http://bellengineering.net/Pages/intheshop.html
949racing and gearhead garage will be selling the qmax soon.
Pauls was made by TurboTim, it was a custom job.

thanks! ill read up on it, does anyone know if one way is necessarily better then another way? I know some people are saying route the coolant around to the intake side so it doesnt get heated even more. sounds logical, any other tricks? i need the most amount of cooling possible... thanks for your help guys... next weekends project.... stage 3 clutch, newer 5spd transmission, new fans 1975cfm each, and coolant re-route, then following WBo2 sensor, walbro 190HP fuel pump and maybe a new exhaust

Make a spacer for the back of the head, put the heatercore and temp sender in the spacer, then bolt the 1.6 outlet to the spacer, weld a hardline to the outlet and fab the rest up to run coldside around the motor to the radiator, join the hardline to the radiator with a hose and you're done.
You can see how the spacer is used here. http://users.telenet.be/miata/englis...nt_reroute.htm

This is what I did. Got a new top hose made up outta alloy, and a new front housing to move the ecu thermoswitch there. I have MSPNP controlling my fan but you could always get a bung welded into the new top pipe for the sensor if you wanted. its just runnig the stock housing relocated to the back of the head.
Seems to work really well and is pretty neat. As an added bonus the front of the new front housing pretty much lines up with the front of the water pump pulley so it leaves heaps of room in front of the motor for a water to air cooler for later on.

not trying to hijack, but i have a similar type question. i have already removed my heater core (along with almost everything else that wasnt welded in). the kit i have is a begi, it comes with a coolant reroute which i ran, but instead of going into the heater core, i just ran it back to the upper radiator hose. i have been told that i can just cap it off, will this limit circulation at all? if not, i would like to remove it comepletly, and if i remove it completly, what do i use to seal up the out coming off the rear of the engine under the coil pack?

If you haven't pulled a line off the back to the top of the radiator, then blocking the Begi will cause you to have NO cooling at the back and will probably cost you a motor.
The Begi unit is used just to get the line for the heater core away from the turbo and give you a return route.
Optimum routing blocks the front thermostat port completely, sends the water across all of the cylinders and out the back and then on to the radiator. If the heater core is left in the circuit, the thermostat requires a small hole to make sure there is enough flow that the thermostat sees the temperature rise.
In a system like Paul's, the thermostat has larger holes drilled in the flange to make sure there is flow over the back of the engine at all times, since the heater core route is no longer available.

what does that do in pauls situation? provide more cooling?
