Any reason you decided to put the T in the lower radiator hose instead of the upper radiator hose?

Its not a coolant reroute at this point. That just moves the coolant lines out of the way for the turbo.

Yes actually. To prevent the motor from running too cool and staying forever in warm up enrichment mode. With the cooler temps we have seen already(60s) my car with the t-splice in the upper hose had trouble maintaining high enough operating temps. I have since moved it to the lower and copied what I did for Artie.

Ha, That is something I wouldn't even think of since I am so used to my Texas climate. Makes sense.

I use the heater core line to feed my turbos. Keeps you from having to tap that water neck on the water pump. Instead of JBwelding the large 5/8 barb on the T fitting, just use the smaller 3/8. Unless you also need a port for the return line from the throttle body, in which case I'll shut up now.

need to get the water out of the heater core back into the front of the engine. the factory mixing manifold doesn't fit with that turbo setup so that's how we roll.

Update- should be getting the couplers in today and have it out on the street later on. But in the meantime, here's some pics that Tim took of the downpipe/exhaust he made and some comparison pics to what paul has.

In case anyone is confused that is my exhaust mirrored so as to make it easy to compare to Artie's. On my car it exits on the driver's side(LHD car)

All done with a few exceptions:

Artie couldn't find a K&N at the local auto parts stores that fit so we temporarily installed the way-too-small filter that came with my BEGi S kit.

Getting a lil turbo flutter with the non-adjustable FM BOV. Guess he has to look into a lighter spring.

Stock clutch starts slipping as soon as you get into boost down around 2600rpm. Thing was making 4psi at 2200. Artie has an ACT XT clutch waiting to go in. He's just a lazy bastard.

Very nice setup so far man
