Thread: tdi engine into series 2a

Have a look here

http://www.glencoyne.co.uk/200di.htm

It's a bodgy effort, but shows it can be done. Not sure if you would get this registered in any state (even QLD) though...

actually with an engineers report for the mounting of the engine you probabley would get away with it in qld as the 200 TDI is basically the same spec as the original 2.25 but with a better head and higher injection pressures. so maximum power is not much more than for a top condition 2.25 petrol engine but the difference is all the torque is low down , (which he stated on the site)

because of the minimal changes in power you probabley wouldnt even need to change the brakes.

Have a look at the Series 2 Club Forum, (which I can't get to work right now). We've had a long discussion about this, and one member has documented his conversion. There is a lot of really good information, mostly about all the little details these sorts of things usually involve.

2.25 Petrol - 77/81BHP @4250, 124/127ft lb @ 2500 depending on 7:1/8:1

200Tdi 111BHP@4000, 195ft lb @1700

Is a 37/44% power increase "minimal"?

The transfer case would certainly stand the torque, as would the Salisbury rear axle (not standard on any 2a), and the 2a gearbox might - but the Rover rear axle certainly would not. The difference in maximum rpm plus the extra power would probably leave it undergeared, although larger tyres would likely offset this.

It would be OK with a light right foot and would run very nicely - but I expect it would be easy to break things, and you would really want to at least fit six cylinder front brakes and probably a booster.

A 200Tdi from a defender bolts straight in as long as you move the battery box and the engine mounts. A disco 200tdi will too if you make a funky dump pipe for the turbo so it clears the firewall.

300Tdi is a bit more work.

I don't know the current rules in QLD, but it used to be that you multiplied the capacity by 1.4 for a turbo (2.5x1.4) - which was above the maximum permitted engine size for a SIIA SWB but not a SIII.

how is it then that you see some landys with v8's in them still running the same drive line .... Are they still rego'd to the original engine and just taking the chance they don't get caught ? ... And if i was to stick with the 186 holden donk do i need an engineers for that in Victoria ?

Rules vary from state-state. What is legal in one state isn't in another and vice versa (until the NCOP comes in).

QLD rules are that you need a Mod plate for any engine conversion except a factory (bolt in-out) option. I'm sure you need an engineer's certificate for a holden conversion in vic (or a tdi conversion).

but what are those numbers when the engine has no turbo charger....... re-read the conversin site again...
