Hi guys.project sj turbo needs some info before start.
Due to space lack i was hoping for a water intercooler.Can anyone confirm if i could use an automatic vitara radiator to plump the extra ports on a second small front mounted transmission radiator that cools the water on a water intercooler?
This way i use my waterpump and keep things simple.
Turbo is tf035hm forester on 0.5bar.Is this efficient?
The rad is this https://rover.ebay.com/rover/0/0/0?mpre ... 2611083006

Water intercooler will only reduce inlet charge to the same temp as coolant, somewhere between 80 - 90 degrees C. Air intercoolers will get down closer to ambient air temp and with water spray even cooler. Even using a small air charge cooler would probably be better than the radiator method.

Trying to piggyback a water to air setup off the engine cooling system is not smart. It needs to be a closed system with a heat exchanger. You can get them below ambient air temp under the right conditions, but they're really only preferable if space is not available for a decent air to air setup.

Space is very tight under my samurai hood.Cannot put a front intercooler.And i want to prevent heat soak conditions like stuck on mud or trying to climp an objstacle.
Yes YLD80Y i will get a closed system with an auxiliary pump for the water intercooler.What about turbo coolant lines?Can i route them to an automatic radiator?Or avoid an auto radiator and get them from near the intake valve?
Somewhere was a diagram for the coolant lines but i cannot find it.Teamswift is closed btw?

If you are going to run a water and oil cooled turbo, then it would be best to cool the intercooler and turbo together I think, on a separate circuit from the engine. I would suspect you will need to run an oil cooler also.

Heat soak conditions will occur at low speeds even if you have a water-cooled intercooler. Your secondary radiator will need an electric fan that is thermostatically controlled to keep the coolant cold enough to remove the heat from the water-cooled intercooler at low speeds. Plus the extra ancillary water pump to pump the coolant.

It sounds more trouble than it is worth, especially for space savings....

I've got a little bit of experience cramming turbos into small engine bays, and I reckon there's enough room in the front of a Samurai for an intercooler.

I already run an oil cooler with a thermostatic valve plate that open above 82 and sends oil to a toyota oil radiator in front of my water radiator.its a custom sj410 with the metal grill and g13b motor is moved alot front for dizzy clearance.I mean no room for fmic+piping.

I will add another small radiator next to oil radiator and connect this to an aux pump loop to water intercooler.In heat soak conditions my radiator fan will pull air from both radiators.But it will have to be strong enough.Its gonna be tight.But i think its doable..i keep you informed.thanks
