Turbo Conversion!!
Discussion
Hi lim a new member and im wanting to put a turbo on my clio 1.2, im looking at a punto GT turbo to install as its a 1.4 turbo and near to my engine size, im just curious to know if this would be possible ??? and also if i can use a dump valve with a standard turbo?? replies would be great i would also wanna know how the setup would go about??? thanks guys

Best advice, don't bother.The cost of the install and the insurance hike wont be worth it, especially as by the time you have done the conversation your car will probably be worth about the same but you will have spent several grand on something that really isn't worth it.
Save your money and when you can afford something with a bit more performance buy it.
To answer your question, anything is possible but just because it is possible doesn't mean you should do it.
A turbo conversion on a naturally aspirated car would cost a lot and you cannot just plonk a turbo in without having to strengthen the internals. Why not just save up and get a bigger engined car at a later date? You would probably be better off getting a clio 182 when you can.

Just buy a Punto GT Turbo.i understand but i wouldnt be paying for the conversion because my dad is a mechanic so we would be doing it but i would just be paying for the parts i.e the punto turbo, intercooler n new manifold to suit so it shouldnt cost that much it just finding the parts cheat what u think, n i also have changed the car allot in looks so wantin to keep it a couple yrs before i can afford bigger, i got scorpion cat back exghaust n body kit so wantin to keep for a while but wantin more power what can you recomend aswel as the turbo project im wanting to carry out?? thnks guys

Just buy a Punto GT Turbo.Why would anyone want to turbo a 1.2 Clio? This is a wind up surely?

How much is the insurance hike?I really dont think its worth it, for all the hassle involved you may as well just buy a turbocharged car to begin with.

Forget the 1.2 engine then as said above.Stick a decent engine in the car, I should imagine a 1.2 clio won't cope well with a turbo and may just blow itself to pieces.
If keeping the car is a must, then the engine swap is the only logical way to go.

I don't want to be rude, welcome to the forums and all that, and I'm glad that you're trying to make you car more interesting performance-wise, so good for you. But I'd be tempted to side with the others unless you really know what you're doing. Maybe hack round for a couple of years in your standard car, save up, then buy something that may be more suited from the factory (how much are 200sx's now?)At a rough guess, on one of those engines all else being equal, on stock internals you're limited to to about 7psi. that would be equivalent of a 50% bigger engine, so if you're determined to do it, why not plonk a 1.8 engine in? It would probably be easier. I can really recommend getting hold of a copy or ten of a magazine called "Practical performance car" it goes into the kind of home improvements you're talking about. if it doesn't help (though it's recently done a series on home-turboing) it's a good read anyway. No I don't work for them!
The bit I've bolded is what's given me some concern that you may not fully understand the systems involved. Though you've come here for information and advice, which is laudable. So I'll tell you. And in 6-7 minutes, someone will come along to tell me I'm wrong!
An awfully large amount of petrol turbo'd cars have a dump valve as standard. It's a relatively common feature. However many are of a recirculating nature, so don't give as prominent a "pssh" sound as some like. Without one the turbo would stall when you shut off the throttle. The compressor is sending all this high-pressure air through the throttle to the engine, but suddenly, the throttle's closed! (There's some natural delay from your foot being let off the accelerator, to the engine slowing down, to the exhaust gasses slowing down the turbine blades. This is not "lag" as commonly used, but it is related) It has nowhere to go, so it backs up to the turbo, and can stop the blades spinning. So all that excess pressurised air is "dumped" to the atmosphere to stop this happening.
There's also something called a "wastegate"on the exhaust side that is what controls how much you pressurise the intake air. So don't fall into the common trap of thinking they're the same thing.
Do stick around though. And good luck whatever you do
Phew! I need to sit down! Oh, I am. Well, I need to go to the pub then. Se y'all later.
EDIT: Happy now? You pedantic buggers!

You're wrong. All petrol turbo'd cars have a dump valve as standard.
Do I get a prize for beating the 6-7 minute estimate ?

As for why, who knows, cost reasons maybe? Most modern OEM BOVs are recirculating and dont vent to atmosphere.
Wouldn't you be better off going with the volvo 480 1.7 turbo lump, that being a relatively straightforward conversion being basically a renault engine. Plus you can pick them up for pennies, then if you want to, spend a couple of hundred on parts to recon the engine and then slot it in.
Sure, these days there are much better modern engines about, but its a highly effective _low cost_ option.
You might want to stiffen the front of the clio up though, I know of one with the conversion and then the 175bhp modified ECU in it that when on boost you can see the panel gaps between the wings and the bonnet change!
I don't agree with those that say don't bother, I mean at least you aren't sticking loads of fibreglass all over it (are you?) however the reasons they give for saying don't bother are correct, mainly:
It will most likely devalue your car.
It will cost "some" money to do.
You will still only have a clio at the end.
If you are going to be doing it yourself, and you want the experience working on cars and engines doing such things, we've all got to start somewhere to learn, and it would be a good project. And then theres the satisfaction of turning the key on a car you have fitted the engine to yourself, so go for it.
Just re-read and realise you want to put a turbo on the 1.2 engine...err, I wouldn't bother with that either, TBH, but still.
