TD04 Turbo

Theres a lad at work converting a mazda mx5, he is after a TD04 but he said there are 2 types, a TD04H and a TD04HL?????

Is he right??? I said id ask for him, can any of the turbo guru's shed somoe light on this please?

He said the TD04hl has a bigger compressor wheel so he's after the one with the smaller compressor wheel

Im sure 1 stands for Hybrid.

Need to know for sure mate, want facts so i can let him know exactly what the crack is

think ill tell him to google the fekker

Ha its amazing what a bit google can do for ya!

All i needed to know

The TD04L differs from the standard TD04 only in that its exducer is about 0.15-inch larger in diameter. A compressor and turbine wheel have two basic diameter measurements, the inducer -- where air goes in -- and the exducer -- where air goes out. In an exhaust turbine wheel, air goes in through the larger diameter portion and spins out through the smaller diameter. An compressor wheel is the other way around. The TD04L uses a turbine wheel with a 1.86-inch inducer and a 1.62-inch exducer, up from the TD04's 1.57-inch exducer.

An exhaust housing size and design is only half the equation, playing a large role in determining how fast the turbo spools up and the maximum capable rpm, but having little to do with how much air the turbo can actually pump. The compressor size and design determines how much air the turbo can pump and ultimately how much boost it can produce.

So he wants a std TD04

See. Told ya lol

TD04HL has a larger 19T compressor wheel, the standard TD04L has a smaller 13T
