Title: 147 Engine mods
Post by: CeeDee on May 14, 2021, 09:28:21 PM
Hi, my name is Christo, 1st time posting. Was looking at getting some engine mods done to my 2009 147. Not sure exactly what yet. Any recommendations of who to talk to?
Thanks in advance.

To be honest Christo there is little one can do to the 2.0 TS engine that will make any worthwhile performance increases without spending a fortune.   :(

I am assuming you're referring to the 2.0 TS engine, right?   ???

Hey. Thanks for the info. Yes it is the 2.0l TS. I was hoping there would be something fairly easy to give it a little bit more acceleration.  Thanks.
Cheers

Christo, I know it may be of little consolation but if you've got yourself a nice 147, you've got a nice car!  You may arrive slightly later, but in far more style.

Hi Christo.  A good place to start will be confirming the engine is in 100% state of tune.  New plugs?  Clean air filter?  Engine oil not too viscous?
Then reducing the weight of the car.  Everything out of the glove box?  Nothing in the boot / hatch?  Washer fluid reservoirs at 50%?  Coolant overflow tank at minimum level?  Remember water mass at 1kg/litre!
Then maybe slightly lower profile tyres?  The lower rolling diameter will have a similar effect as a shorter diff ratio.  Speed however will read higher for a given velocity - not a bad thing!
Choice of tyres - the best you can afford!  Lots of tyres out there now that provide good grip and low rolling resistance.
Tyre pressures - no less than say 38psi.  This will further reduce rolling resistance - then check the pressures weekly.
Wheel alignment.  Take the car to someone who knows Alfas AND has an on-site aligner.  Front and rear toe should be at the minimum end of the scale if your want better acceleration / lower mechanical drag.  If you still want it to turn into corners like a 147 should, toe should be set as per the Alfa experts recommendation.

For what it's worth, I fitted one of those throttle remap devices to my 147 (I bought a HikeIt unit for around the $200 mark).
Plug and play, it piggybacks between the throttle pedal and cable.
It doesn't increase engine performance but there are a multitude of throttle response settings to choose from.
I use a sport setting and instead of the factory doughy response, you get a lot more go with less pedal movement.
Overall, in my opinion, a good upgrade for the money.

The 147 is par for the course for naturally aspirated 2L 4cy engines of that age. For comparison I had a 1993 N14 Nissan Pulsar SSS 2L that was rated from the factory at 105kW / 179Nm, pretty high outputs for the time and similar to your 16 years younger 147. With a unichip, K&N panel filter, custom extractors and 2" exhaust it made 105kW at the wheels on a dyno,  quick enough to keep up with XR6 Falcons of the era.

Have a look at autodeltashop.com for some 147 mods, won't be cheap though.
