Hello new to this site...and am in Spain but British. Need help on daewoo matiz tuning

[Special1854]

Good day
I am new to this site, and hopefully can gain some tuning knowledge on a daewoo matiz 3 cylinder.
I would like to know if and what is available to extract more power from this engine..
However, if the site helps and advises it would be better to modify the 1 ltr then, l would listen.
It is simply the engine and gearbox that l will be using.
It will be put into a special, that will be used in car trial..ie green laning rough ground mud tracks..etc.
So l will need a bit more hp and torque..
Can this engine be bored out and if so to what size..
Cams...are they available, injectors too. Clutch...upgrade..
I can flow the head and get it skimmed..
So will await a reply.
Not sure how this site works but will leave my email...below
I suspect it will take me some time getting the special sorted , so in the meantime will think and collect information on the engine
Regards Simon.

Hello and a very warm, welcome to TorqueCars from me the admin!

So sorry for my very slow reply, I've been busy updating the site framework and chasing bugs. Hopefully we are there now, with a much faster more efficient site and server.

Pushing more power from a 3 cylinder is quite hard, they are not that well balanced and more power will mean faster rotations of the engine. If you start with a larger engine, and preferably a 4 cylinder you have a better base to work from.

You can mod this engine, but for the cost you will not see much difference at the wheels - I have to be brutally honest here, I spend a fortune tuning a car, to see not a lot of gain and wish someone gave me that advice.

One mod I would consider though is a better torque sensing differential, this will give much more traction and will stop the car getting stuck in mud as it sounds like that's your thing.

I'm sure you'll fit in just fine and look forward to Talking Cars with you.

Keep reading the articles on our site and this forum... you'll pick up loads of good common sense tips and don't be afraid to post questions, were all here to share our knowledge and experience.

We run a really fun and interesting car community and many have said we're the friendliest around, always ready to help out where we can.

Enjoy your time with us, post loads and feel free to ask any questions or begin new threads and discussions. We're always interested to hear your comments and views on our existing topics and in the hot polls.

Thank you for your reply.
Actually the diff will be locked up....or welded..so live axle.
The reason is simple..engine mounted behind driver and passenger. From there it will have a chain drive to the single rear wheel ( tricycle or trike)
The 3 cyl engine produces more torque than the 4...( due to the stroke being longer) although the 4 has naturally more power..
I therefore need to keep the weight down as much as possible, but need the weight on the rear traction..
If l have to use a 4 then some it..
But that is not my goal.
I know that l can get some more power/torque, using my own methods..
Just needed to know if anyone had tried...ie what would be the max one could bore it out to.
I also believe it could be re-mapped..but that would be down to a specialist...and on a rolling road.
Anyway thanks for the reply..if you do think of anything else, don't hesitate to drop me a line

An aftermarket ECU will give you plenty of tuning options. Something like Megasquirt and Apexi should work really well.
believe so reboring is not that easy, you can often get thinner sleeves though, providing you can get the pistons to match.
These engines are lined i

I am not after screaming revs..nor a narrow powerband..
Really what is needed is more torque..
I have thought on the route of engine management..too
But remember this will be a tricycle.. rear wheel drive..and l having a weight limit of 450 km.. so put that and engine of 55/60 hp, and that is not bad in the ton to hp ratio..
It's how to apply it, at the rear wheel...on those muddy slippery Cornish hills
Kind regards
