Simpson Off-Road Engineering is pleased to offer a quality oil and coolant supply/return kit for 1HZ-T conversions that will not only look good, but ensure a safe and reliable supply/return of oil to the turbo/sump, and coolant supply and return from the heater hoses on the firewall.

Our kit taps into the oil pressure sensor on the side of the 1HZ block with a brass T-piece, runs oil around the back of the block to the CT26 turbo through a PTFE Stainless Braided crimped hose with billet AN fittings, and then returns oil to the sump. The kit is supplied with a quality nickel coated, welded steel oil supply/return flange and water supply/return flange for the turbo ports. The coolant lines are tee’d into the ‘inlet’ heater core hose, and ‘outlet’ heater core hose on the firewall with the supplied brass and billet fittings.

All lines are Stainless Steel Braided PTFE hoses with max working pressure of 3000psi, matched with crimped AN 6061 T6 billet aluminium fittings for a reliable and safe system. The return line sump connection features a swivel 45 degree fitting for easy install. Our braided lines are all pressure tested individually before packaging.

The kit is supplied with a billet AN Steel weld-on bung for the sump. Using our kit, your sump will need to be removed, a hole drilled, and the fitting welded on. With a welded AN sump fitting, leaks will never be a problem - when you’re somewhere off-road and isolated, you can’t put a price on peace of mind!
