As Koalar has said, the t-jet conversion is probably the best option. Everything you need to know is here, even if you don’t go down that route then there are worse ways to spend a few hours of your time.Yes im toying with the prospects of adding a turbo to a 100hp. Has it been done by anyone!?
There's also the mini Supercharger that could be adapted!?View attachment 475403
Im not after mega Bhp. Im after a nice low down punch up to 70 miles an hour. Not much point having anything more these days with the amount of cameras around.Turbo and mechanical superchargers run low compression pistons because "normal" compression will cause the ECU to cut power to avoid the engine blowing holes through its pistons.
Diesels inject fuel into the hot compressed air. A turbo releases engine potential that can never happen with normal aspiration. A turbo diesel will often have a lower mechanical CR than a normal aspirated. It allows more boost to be used. But the CR difference is less than you'll see in petrol engines.
Not as far as I am awareHas anyone done a Fiat coupe 20V?![]()
My Engine and Gearbox, have 106000 miles. Passed the Mot with good emissions. Gears work Lovely and drives lovely. Think ill definately be doing the TjetYou can't turbo or supercharge the standard 1.4 to make any noticeable difference, regardless of what YouTubers say, the compression ratio is too high
The compressed fuel and air will ignite before the spark
It's right at the border line of being possible if it had direct injection, and very careful tuning, but even then gains would be very limited
Fiat put in a stronger better balance crank, stronger flywheel bolts, different cans, better cooling, lower compression
Engine parts are expensive, I like rebuilding engines, but haven't done one for decades, just the pistons, rods and rings are over a grand, it makes more sense to swap the engine, your old engine is worth £300-700 if it's running okay
I find that difficult to believe, normally aspirated typically ~9:1 typical diesel ~20:1 seems odd that these values could be swapped around. Could you elaborate further with a real example of mainstream passenger vehicle? I may be wrong, (I've been wrong before).... A turbo diesel will often have a lower mechanical CR than a normal aspirated.....
Compression ratio of none turbo VW is 23:1
The TDI version of the same engine is 19:1
Pre ignition is not a problem here with a diesel as you are only compressing air, nothing to ignite untill the diesel is add later, but cylinder pressure are, it's reduced to limit the chance of engine damage and blown head gaskets
petrol is completely different your compressing fuel and air
If the compression ratio is to high the fuel and air will self ignite before the spark
And will quickly melt the pistons
There's several way round this, low the compression ratio, inject water, change the fuel
The 1.4 16v engine is not a good candidate to add a turbo to, the 1.4 tjet was a completely redesigned.
It's not a direct injection engineRight starting to make sense now. But if you had your own ECU couldn't you compress air then inject mixture!? Just saying like.
@Cinq999 on here has a modified 1.3I would prefer to build one out of a 1.1, 1.2 or 1.3 Panda
