Had a wee look on the search but couldn't find a full answer

Is it possible to twin turbo a vRS Fabia? I've the chance of getting my hands on another standard turbo and the old bit grey cells started ticking. I'll probably be shot to bits (as usual) for asking.

I know it would probably cost a fair bit, but what would be required to do this conversion (if its possible)

Right, get thinking :P:D

Cheers folks..................

what do you mean when you say twin turbo's? two equal size turbo's, or one large and one small.... anything is possible with the right skills but it probably isn't worth it anyway

One smaller, so it will spool quicker.......

Dont think there would be much point in 2 the same.....or would they?

Its just really a thought, you know the whole "dont think anyone has done it yet" or "dare to be different" lol lol

ok, on a 4 cylinder engine there is probably no point in having 2 equal size turbos, where they really come into play is on v6's and v8's where the cylinders are arranged in banks so the turbo is as close as possible the the cylinder heads...

sequential turbo's (one large and one small) this can be a good way of making lots and lots of power, but it is fraught with massive headaches involving bypass valves, non-return valves, and lots of vacuum/boost hoses, and tbh with the advent of vnt turbo's used on the diesels it kind-of does away with the need for it altogether... some old'skool porsche's and iirc the nissan 200/300 has them

Ah i see. I knew there was alot involved, but not that much lol I also understood that it wasn't a case of "buy it n bolt it"

If there is no real advantages of even attempting it then i think i'll look into something else........Supercharging anyone??? :P

Yeah it can be done, but on a Fabia, there isnt a lot of room, and not a huge benifit.

If your thinking about twin charging, a Supercharger with a big laggy turbo would be a better idea.

Having said that, Air Con would have to come out I think, and the internals of the engine would need a fair bit spent.

I have been looking at a big S/C for my vRS, but still um'ing and ar'ing at the mo. Reason would be is to loose some of that heat a Turbo makes. And I could do all the work myself, bar the mapping.

Also, who doesnt like the sound of a screaching S/C.

Only biggy with a S/C is they like to be services every year at least (if your running big power or an aftermarket one), unlike the turbo setups, which you can just drive for years without much trouble.

HTH. Dave

fancy the SC because of the noise and the fact that its "instant" power delivery with no lag. Think i'd want the charger to kill the lag before the turbo kicked..............

Oh too many ideas and not enough time and money lol

Wont work, as you would need to split the turbos to work on two cylinders each (double exhaust system) So same volume of air would get moved anyway. In fact you would lose power, as the exhaust gas flow over each VNT would be halved, lag would increase as well.

I like your thinking but..............................BAD IDEA

Sequential would work, but as already said, plumbers nightmare. Think TFSI with a supercharger. Golf 1.6 TFSI petrol would be cool

Find yourself a stuffed Mk4 Ibiza Cupra Petrol and swap the engines

I know Kev at Jabba was up for it so you'd have the support of them I'm sure!

Not interested in doing an engine swap tbh Dont see the point in changing engines until it goes bang lol

Nos and water meth?

Oh i dont know anymore :rofl:

I am surprised that no cars are fitted with a supercharged diesel because they work at low revs. I have seen and worked on a 7 or 9 cylinder two-stoke boat engine before. It had 2 or 3 superchargers, a turbo the size of a car and pistons of 1 foot (30cm) Diameter.

The only twin charger engine is the 1.4 TSI VAG one in the Golf GT, new Ibiza and hopefully the new Fabia vRS. These are Supercharged and Turbocharged.

I think the Vectra and others have Twin sequential turbo's, one large and one small on a diesel to help remove turbo lag, I don't know how good a bigger turbo with Variable vanes would do.

i just want an instant boost tbh..........charging it SOUNDED like a good idea after the initial twin turbo thought lol

I am surprised that no cars are fitted with a supercharged diesel because they work at low revs.

you mean an Sdi fabia?

Haha Wilf...

SDI stands for Suction Diesel Injection

Not Supercharged lol.

Doofus..

Doofus..

i have to get one wrong once in a .....day LMAO

Doofus.... haha, what a word. Not heard that for a while.

Get a S/C off a rangerover or small truck, or you wont make power.

Do it. Now.

The drivability of a S/C car is soooo much nicer than a turbo'd one. And the torque line will be flat as.

been thinking more about the charger option.............dont know where to start looking for the bits.

All help/advice would be mucho appreciated

I though about putting the Eaton M45 on a VRS when i was first thinking about buying one! I use to own a Polo g40 and loved the instant boost and blow-off whoosh!

Mazda did a Comprex diesel engine in the 626 years ago, that was a supercharger.

So this is a feasable idea and not just wishful thinking? I do like the charger noise and think coupled with the turbo would be pretty devistating

Trust me, super-chargers are a bitch to graft onto an engine not designed for it. It is possible, but given that one of our members in the Morris Minors Owners Club has been trying to get an A Series engine to run sweet with a super-charger for 2 years, does not bode well for an ECU controlled diesel.

Interesting engineering problem though.

1: SC mounting location

2: SC drive from engine (Needs a belt drive)

3: Intake Air flow changed (MAF/ECU/Fueling)

4: Pipework

to be fair, an a series morris engine is difficult to get to run right without a supercharger strapped to it... i reckon that the turbodiesel engine will more than be capable of coping with supercharging even with the standard internals, you'd still have a mass of pipework and bypass/non-return valves though, then a custom remap... of course fitting the damn thing to the engine is a bit of a challenge, there aint much space to play with but i'm sure it could be done...

but in all honesty, from my experience of eaton blowers it would be very dissapointing on a diesel engine, they simply dont make the high charge pressures that you'd need, plus you have a constant parasitic power loss through the belt drive (unless you incorporate a electronic clutch on the blower pulley like the mercedez M45 blowers). fwiw i reckon you are better off sticking with the vnt turbocharger and having a fiddle with that instead, maybe you could torture an old turbo and take it's compressor housing for a DIY hybrid

Just turn the turbo into a experiment, using it as a minature jet engine instead

Hmmm...........i've found out that i can get a PD130 turbo with a goosed shaft. How much to replace the shaft and do a "diy hybrid" on it...............

Although i fancied twin turbo/SC the furby, taken under advisement by you guys, i think its an idea for a bigger car, with more space

Thanks to you all Once again this site proves invaluable

it's not a DIY job to fit a new shaft because the shafts and impellers need dynamic balancing as a complete assembly, think of it like this... they have to spin at very very high speeds and any imbalance would make it vibrate and wipe out the bearings.... it may however be possible to find the bits you need for a DIY hybrid then visit a turbo specialist to get them to balance it for you, you may be able to save a huge amount by doing it this way rather than using an off-the-shelf hybrid
