Ultimate Cooling Package for the 1990-1996 Twin Turbo 300zx.
This package includes cooling accessories for the Twin Turbo Z that will yield increased power and response due to the elimination of parasitic losses from the stock belt driven fan while keeping engine temps under control. Featuring a Z1 / Howe Radiator, Z1 Radiator Cap, and SPAL 16" Electric Fan kit.
This kit includes:
Available as an option below is the SPAL 185TS thermatic switch turns the fan on at a temperature of 185 degrees and turns the fan off at 165 degrees. Also optional is a modified Coolant Temperature Sensor Adapter for ease of install.
Select the standard or high amp fan option below. The standard fan and high amp fans flow roughly the same volume of air up to 5 mm H20 static pressure. However as static pressure increases the high amp fan increasingly out flows the standard fan. The high amp fan requires significantly more current to operate and may pull up to 30 amps under high load. The high amp fan includes a considerably heavier and more expensive wiring harness and relay. While the standard fan meets the cooling needs of many street driven Z32s, the high amp extreme performance fan is often required for more demanding conditions, track use, hot climates, or on Twin Turbos with a tendency to run on the hot side often because of other issues. Z32 owners should ALWAYS keep a close eye on coolant temperatures and aftermarket gauges including warning lights are recommended.
Automatic Transmission owners PLEASE NOTE:
This high performance, aftermarket radiator DOES NOT include an integrated, internal transmission cooler. Customers installing this radiator into an automatic transmission equipped vehicle must add an external transmission cooler. Z1 Motorsports stocks and sells a variety of both universal and vehicle specific transmission coolers which can be found Here.
Please Note: High Amp fans require modification of the "gasket" for proper fit.
