What is the difference in 1.5 DCi Engines

[montfish]

Apologies if this is in the wrong section.

I have searched for the answer to this question, but have been unable to find out the information i needed.

I have a 1.5 DCi Megane, the 80 bhp version, and i was wondering, what is the difference between this and the 100 and 106 (i think) engines respectively???

Thanks for the replies

other than the gear box, and a remap, i don't think theres any difference

100HP and 106HP have different turbo: multi-vane variable nozzle turbocharger. Only 106HP comes with Renault/Nissan 6-speed gearbox. The difference between 100HP and 106HP is in the injection system: 106 has six-hole piezo-electric injectors and 100HP has solenoid injectors. Injection pressure is the same though. Another difference might be that 106 version has more reliable injection pump than earlier versions.

I have a 1.5dci 80 bhp and a 1.9dci 100bhp, theres only 10mph difference in top speed but obviously the extra 20 bhp helps alot more with acceleration

I didn't believe the turbo was bigger...i thought it was due to no intercooler on a 80bhp...Intercooler on 100bhp and intercooler and increase in map for 106bhp (6 speed included)

theres intercoolers on the 80 and 86bhp models

Cool cool Didn't know that now! Cheers for that!

It's the 60-odd bhp variant in the older clio which hasn't got an intercooler.

Correct. !.5dCi unit with 65/70HP has no intercooler. It is used in Dacia, too.

Buy a 1.9dCi. The easiest way by far.

We have only 1.5 DCI MANUAL, all the others are aut' .

By the way,I saw your signature, and my fuel( i dont know how to say it, i hope you will understand it) is 9.1/100 in town for a tank.
Is it ok?

[Poddy]

thats very high, how do you drive your car?

[UnrateD]

I dont drive like a maniac, but i also like sometimes to be the first in green light.
Usually i drive normally. Between citys it shows 5.7 crusing 100 km/h and 6-7.5 crusing 115-120.
When i bought this car i thought it would be economic as i read: 1:22 in town lol.
