You know the surfs have the temp guages with the factory resistors in them which make them read cold/normal/hot?, ie they lie sometimes?, theres a thread on pirate? on this?

2L-T
The 2L-T is a 2.4 L (2446 cc) turbo version of the 2L still being produced since 1985. The bore and stroke are the same but the 2L-T has a compression ratio of 20:1. Output is 86 hp (64.1 kW) at 4000 RPM with 139 ft·lb (188.4 N·m) of torque at 2200 RPM.

2L-TE
Developed as a new version of 2L-T, the 2L-TE features a new development used in Diesel engines at that time, the EFI (Electronic Fuel Injection) system. Although Toyota used this fuel injection system in gasoline engines years before, this is among the first Diesel engines to adopt such a system. Although the basic construction is similar to a modern gasoline injector, the EFI system in 2L-TE utilize considerably higher injection pressures. The EFI system meter fuel with great precision and succeeded in increasing the engine's efficiency. Like the 2L-T , it is 2.4L (2446cc) and it is a SOHC (Single Overhead Cam) engine, having 8 valves. It also comes with a Turbo charger. The bore is 92 mm and stroke is also 92 mm. Due to the EFI system, the 2L-TE is stronger than 2L-T, having maximum output of 97HP (72.3kW) at 3800 RPM and maximum torque is 24.54 kg.m (240.3 N･m) at 2400 RPM. Redline of this engine is at 4800 RPM. Compression ratio is 21.0 : 1, slightly higher than 2L-T. 2L-TE was replaced by the KZ engine in the year 1993.

hi dude im sorry to say it but would bet my left testie that its a hairline crack in the head have found from past surfs ive had they will run ok on the road but once they start working hard the temp goes through the roof and has always been a crack in the head that caused it easy fix throw a 2.8 hiace motor in it............you can get new head from bnt bout 650 last time i looked

have you locked your viscous fan?

[Rypuppy]

Is there much hassle chucking a 2.8 hiace engine in them? Like gearbox mounts, engine mounts and so on?

easy to change to 2.8 you need to change sump and oil pickup from 2.4 and to be safe use the engine mounts as well everything bolts on sweet and the exhaust will need modding you may need to swap alt as plugs are normally different but bolts straight up
