The coolant comes out the other side and into the coolant pump. Eimer Engineering fabricated a simple bracket to mount the coolant pump. The coolant leaves the pump and heads behind the radiator.
Here’s the pump outlet hose as viewed from behind the radiator. Those are the front sway bar, coolant hose, and driver-side fan for reference.
It’s not a good picture, but I have a T-fitting in there. The straight-through flow path is from the pump outlet to the intercooler inlet. The side branch goes to this Moroso tank mounted with another custom bracket. I’m using the Moroso unit as my coolant reservoir and expansion tank. It’s actually categorized as a power steering fluid reservoir. It’s all a tight fit with the intercooler coolant hoses snaking between the air conditioner and engine coolant hoses.
It’s mounted where the cruise control module used to sit. It’s very hard to see, but there’s a tiny hole under the middle ‘O’ in Moroso.
Underneath the cap, you see this fancy filter. It’s basically an air oil separator I think when the reservoir is used in its intended function as a power steering fluid reservoir. So, it lets air in and out to account for thermal expansion and contraction of the liquid in the system but it does not let the liquid out. Finding the little breather filter was a nice surprise as it isn’t mentioned in the product details. It does make me feel better about spending the money on this Moroso! There’s a nice fat o-ring on the cap for sealing too. For a simple reservoir, this Moroso unit is quite nice! The details of the cap and the rounded corners of the main body are nice design details that make the unit stand out.

That AN line kit is pretty cool, I haven’t seen that before.
Do you still have that alternate vented hood? Seems like it would come in handy to dissipate the heat from the turbo considering how high that air intake is in the engine bay.
Glad to finally see another post on this car. Always loved the chassis, it just needs some power to make it golden.
I gave that hood to the owner of Project AP1 S2000. I’m staying completely stock hood sticking to the sleeper stealth theme. A NACA duct right in the middle of the hood where the intake is would be optimal, but that would attract unwanted attention. While sitting stationary, the intake will suck up some of the warm air coming off the manifold/turbo. But I figure in first gear, the car will be traction limited anyway. Once the car is moving, I’m plumbing cool air towards the intake, so it should be sucking in near ambient temp air. We could possibly fab up an airbox to completely isolate the intake from radiator air, but I don’t think it’d be worth the effort.
That engine bay is looking mighty crowded, I don’t know if you could get some kind of snorkel to vent into the air filter like this:

Yeah, I understand wanting a sleeper. I had my first car stolen within six months because I put some chromed aluminum 17” wheels on it. When I got it back (with some crap steel wheels) I used the insurance money to search for the lightest, yet stock looking aluminum wheels I could find. I eventually turned it into an auto-X car, but I was always mindful to remove the race wheels and slicks immediately before going home.
Because of that initial experience, I have always tried to make my street cars look understated. I absolutely subscribe to the ‘sleeper ethos’….because, as you say ‘life.’
I have to admit… I was eyeballing a Dodge Viper hood NACA duct… I talked myself out of it to stay under the radar. Some of the air from the driver side bumper duct will work its way into the engine bay. The passenger side bumper duct will be the primary way to plumb ambient air to the intake. When the front bumper is fully mounted, there may be a gap between the top of the heat exchanger and the top of the bumper opening. If so, we can make another air diverter plate to force air to go over the top of the radiator like the snorkels.
Great build! Is the turbo manifold available for sale? Ready to purchase
I’m waiting to get my car tuned to determine the wastegate performance before I sell the one spare manifold. I’ve been driving it around, making sure all the small things are in proper working order before going in for a tune. I’m hoping to have it all ready by the end of September.
