Et3 Motor?

ET3

 

A DOHC 16 valve version of the TU3 with variable valve timing was introduced in 2005 with the Peugeot 307. However, this version was named ET3, possibly as a prelude for the new PSA/BMW Prince engine family.

 

taken from wikipedia. anyone ever seen one? could they be used in competition? do they share the same parts?

 

Model /Output /Notes

ET3 J4/ 90 PS (88 hp/66 kW) /Fuel Injection, catalyst.

Bottom end might be similar, but manufacturers like to continuously change the specs of things like that

 

Interesting to see that with all its fancy bits and bobs, its still only 3bhp more than an '88 TU3S...

There is also an electric-engine (the SA13) for the 106 listed on the parts CD.

a 1400 16 valve motor could be useful to the rallying fraternity, especially against suzuki swift 1.3 16v's, but i suspect that the ET3 and TU3 are similair only in name like you say. ive never seen one, or heard of a 1.4 16v TU.

I have, there was a review of the aforesaid 307 in an autocar a few weeks back. It had quite a nice torque curve IIRC.

could be a possibility for a nice high power 1400 you think? i could do with a spec sheet on it really.....

from the specs - same bottom end as the 1360, same bore/stroke. DOHC 16v head with 11:1 CR, 87bhp@5250rpm - 98lbft@3250rpm.

 

Looks like a really torquey motor compared to the 8v.

The engine block is pretty much the same as 8v TU's and is alloy, think pistons are different and the head design is very different from the 16v TU5. Not sure how good it is for tuning but they are pretty rubbish to drive, don't rev very well, sound rubbish and feel quite flat, although a lot of this will be down to ECU programming and fly-by-wire throttle. Possibly has potential, but you may be better bolting a TU5J4 head onto a TU3 bottom end, it's been done before with good results.

and its making that power with all the 3 way emissions equipment in place, hmmm could be worth looking into.... and also this modern engine is running a stupidly heavy flywheel to make it feel smoother, which invaribly stops it revving freely!

Yup, could make quite a bit of power if you can extend that torque curve up a bit.

the ET3 is a 1.6 16v with VVT and leaky headgaskets...

 

is used in most of the peugeot range

[Gregg 0]

ET3 is only 1.4, the 1.6 16v is still a TU.

 

The headgasket leaks are exactly the same as all the TU's, front right corner above the alternator Although according to Peugeot, it's actually the cam seals........

 

VVT operates on the inlet cam only and is probably used to get that nice looking torque curve and meet emmissions standards, they really don't like been revved past 6k.
