1HD FTE Conversions.
If want your 80, 105 or even a Nissan Patrol to go hard, the 1HD FTE powered Toyota Land Cruiser is a safe bet, and we have played with them long enough that maybe it’s time to chat to us. We have done many conversions and own a number of modified FTE powered 105 cruisers. We can guide you and provide the items required to help you increase the performance of your Land Cruiser by over 3x if you are interested.
At Performance Diesel Intercoolers, our mission is to help you extract optimum power from your diesel engine with the best intercooler kits available as well as other parts to complete the package. Our systems feature the largest core width that you can reasonably fit to optimise cooling and performance.
The Benefits of a 1HD FTE Conversion
Regarded by many as the best diesel out of Japan the 1HDFTE is a relatively simple engine with grea power potential, with good km and is reliable and good for many km. They bolt directly into earlier 1HZ and 1FZ powered Landcruisers and can be considered a factory option and uses factory parts to make it work, which means owning one is easier when it comes to repairs.
We think the FZJ105 is the best starting point, for many reasons and these days would choose the auto option as a stepping stone to doing one of the 6 speed auto conversions we are working on.
Run with an ECU (1HDFTE) or go mechanical (1HDFTM)?
In standard form the electronically controlled injection pump was rated at 121kW for the HDJ79 motor/ECU and 153kW for the HDJ100 motor/ECU with 430 Nm at 1400-3200 rpm; its redline was 4000 rpm.
Once modified, the last of the HDJ100 responds best and a very close second is the HDJ79. The early 100 series engine is a bit lazy and upgrades need to be considered differently. Thats when considering injector and turbo upgrades or just a module.
The 1HD-FTE engine had a service mass of 348 kg for models with manual transmissions and 341 kg for models with automatic transmissions.
We have designed our own wiring harnesses for doing conversions into the early 105, so if all you get is a engine harness we can supply the parts to get into the fuse box and across the dash so installation can be done with minimal impact.
The electronic 1HDFTE conversion will need:
- Engine with sensor and engine harness
- ECU – management system
- EDU – amplifier/spil valve controller
- Accelerator pedal since these are “fly by wire” design.
- wiring to connect power to ECU, pedal, immobiliser, EDU and relays then down to engine harness.
- sump and pickup to suit your chassis.
- mounts to suit your chassis
- exhaust system
- Fuel filter and lines to suit turbo diesel.
- speed sensor input into ECU for it to function correctly (an issue for those installing in early 80 series).
- someone to install everything and make it all work.
What Sets Performance Diesel Intercoolers Apart When Considering a 1HD FTE Conversion?
We have built many and still have a couple of our own FTE converted 105s and they are all pushing respectable numbers. We aim to achieve the best results with the right components. This is from a mild increase to those wanting to see their vehicles pumping out 300rwkw. Our recipe works and you will end up with a reliable and durable system for going on that next expedition.
- We designed our diesel intercooler systems to be the best in terms of performance and efficiency. The size is maximum possible for the space and cooling is as close to ambient air temp as possible.
- With years of research and development going into the design of our diesel intercooler systems, we also ensured that they are manufactured to the highest standard and from only the best materials.
- We offer the best customer service and support available in the industry today. We are always at the ready to provide assistance and advice, and we will much rather lose a sale than sell you something you don’t need. Contact us today, and we will help you assess your performance needs.
1HDFTM Conversion
These can be easier to source than a 1HDFT and the FTE got a few improvements to the cooling system and had stronger casting for block and crankshaft.
If you want to stay away from the electronics and make the conversion simpler, the mechanical FTE option might be worth considering. Keep in mind if you have a late model 105 it might now pass an engineering inspection if you go this way.
For 1HDFTM you will want a complete 1HDFTE engine, minus the injection pump and harness is OK as you will need to get a 1HDFT pump built and can use the engine loom from a 1HZ.
For 1HDFTM you will need:
- 1HDFT injection pump or get a 1HZ pump and have it converted to be a 1HDFT pump.
- Injectors modified to work with the lower injection pressures.
- different rear timing cover or modified rear timing cover to have the 2 bolt mounting (instead of the FTE 4 bolt mounting)
- different upper timing gear with smaller tapered hole to engage on the injection pump.
- bracket to mount the throttle linkages to the side of the FTE intake manifold.
- sump and pickup to suit your chassis.
- mounts to suit your chassis
- exhaust system
- Fuel filter and lines to suit turbo diesel
- someone to install and make it all work.
1HDFTM Compromises.
What to do while its out?
There are many things you can consider such as all seals, bearings, water pump, timing belt, tensioner oil pump seal, injectors, turbo swap etc. Ive never had problems with water pumps but if you want to swap then buying an Aisin brand pump is cheaper and OEM.
Many things are easier while its on the stand, while some can be easily done later. Also working out what’s the final performance objectives to save doing things over. We suggest swapping the turbo while its out since it is a 30min job , compared to a 3-4 hour job later.
