To Turbo Or Not To Turbo

[opiki]

Hi all.

I have just fitted a 2c toyota engine into a portable sawmill, and although its stated torque is higher than the original perkins engine the toyota is struggling to cut in the big cuts.

I have set the engine to run at 2800 its optimum torque range.

The 2c originally came out of a bus air conditioning unit and I fear it may have been "depowered".

Are there any suggestion on what to do to achieve more power.

I have screwed the diesel screw in half a turn and that did seem to help (no exhaust smoke) but are reluctant to wind in anymore.

Are the 2c and 2c-t engines the same and if so would I notice an increase in power if I bolted a turbo from a 2c-t on.

 

Thanks for reading and I look forward to any ideas or suggestions

With diesels (and I'm not an expert) I would assume the turbo version only differs in the fact that its got a turbo strapped on the site. You don't need forgies to cope with possible detonation (because thats whats happening anyway) and you don't HAVE to upgrade injectors and the injector pump but they might not make as much power (and possible other problems may arise such as fuel pressure too low). Youd probably have change the injection timing and fiddle with the enrichment screw until you get it close to right.

 

Id say you'll notice a huge power increase once you put the turbo on. If you can't find a 2C turbo (I think they came on 1950s willy's jeeps from what I can find but no doubt theyre on other things as well) Id go for maybe a CT12 off a 1GGTE (twin turbo). Theyre fairly small, would be good on a sub 1 litre petrol engine, so with a diesel engine double the capacity (2 litres) it should work fairly good (I think). Or maybe a Garrett GT12 if you wanted something that you could buy new. Rated at 120hp on petrol engines and costs around $650USD new.

i'm unsure if diesel and petrol turbos are the same, i believe they have different A/Rs to suit the different flow characteristics of the different engines
