On a side note and update, the reroute is great, but routing the heater return back to the rad after the thermostat does cause super slow warmup, and in the cold weather, I can't get my coolant above ~160F. While I'm sure that this will be awesome on a hot day at the track, I think I will probably modify my setup in one of four ways:
1) Run a radiator blocker in the cold weather like trucks do. (I think paul made one for his car.)
2) Put a valve in the heater core return to the radiator and almost close it off in the winter and open it for track days.
3) Put an inline thermostat in the heater core line (if they make one that small).
4) Take the thermostat out of the back of the head and put it somewhere after the heater return.
Not sure which path I'll take yet.

also i think you said you were running 3/8" line for your heater but were going to run a shut off valve... does this mean you would recomend a smaller line?

im in the process of doing my re-route, i was thinking about mating the heater line with the coolant line after the thermostat... any feedback/thoughts on it? turbo tim told me he wasnt sure but if i welded them together on a small angle theoritically it should create a suction...

So for you, I'd either try to put the heater return BEFORE the thermostat or put a serious restrictor into the heater core return line before it merges into the radiator return. YMMV.

sorry about that brg, i meant to say BEFORE. so you are saying its a good idea to do it before? because tim said he wasnt sure if it would work alright... to be honest, my temp is so high currently... on the track in 5 laps without the heater on the cars at 3/4 of the way over on the temp gauge... as soon as the temp passes half way all my power is gone... you have a Link... do you know of any way to help this/ tune the link because nobody can help me with it... not even the tune shops.

hmmm... i have an aftermarket rad.. its a 2.25" rad, not sure of the brand... dual core. i think its about 5yrs old, drained it last year. im not exactly a genius when it comes to radiators or the cooling system so where can i find/unclog the small passageways? just ordered an inline t-stat housing and 180* t-stat from shore motorsports. I am going to work on the car either tomor or tuesday, im going to bring my camera to take pics

nice setup brgracer, I'm gonna add it to my page of coulant reroutes. It's been a while since I updated the site, but a completely new site is in the works!

Nice job, brgracer. What do you use for a coolant supply to the turbo? I used a J-shaped piece coming off the coolant pipe (green arrow in pic #1), but was wondering if there is a better place. Anyone else?
I've also turned the t-stat cap pointing to the intake side. My thermosensor is in a fitting I got from BEGi -- it's a nice billet piece that's tapped already, and fits inline with the larger hose that goes to the top of the rad.
On another note, for those of you wo have removed the t-stat neck, how do you route coolant to/from the air valve on top of the intake manifold?

olderguy: doesn't make sense because they both have coolant coming OUT of the thermostat neck (since it's a tee). Am I wrong in this thinking? It's been awhile since I've looked at where those hoses go/come from in an OEM application. Anyone have a diagram of where they go? I can't figure it out from the diagrams on the m.net/garage parts index.
