Re: can i turbocharge a favorit

In all probability, yes, BUT how strong the engine internals are will govern how much extra power you can achieve and how long the engine will last with the extra stress. I'd not bother really, find something more powerful. Looking at your location I'd have thought parts would be a problem too.

Re: can i turbocharge a favorit

You can turbocharge any engine.
How long it lasts depends on how much time and money you put in. Safest way would be to start with as late an injection favorit as possible.
Rewire the engine loom to run a megasquirt ECU witha 3 bar map sensor and GM coolant and air temp sensors. Torque the cylinder head down, and don't run more than about 6-8PSI boost through a good intercooler.
See if you can add a second injector on the second bank of the megasquirt injector lines, to the inlet and use the ECU to control the necessary fuel enrichment under boost.

It isn't a weekend job, probably weeks in the doing, and months in the planning getting the parts togther. You might be able to use some of the parts from a later fabia, and use the turbo from a turbo diesel as they tend to be small for the size of engine, compared to the petrol equivalent.
Don't forget you need to work out oil and water lines for a recent turbo.
Junk Yard turboing can be done, just means you either spend big bucks to get it quick, or wait long times to get it cheap.

Re: can i turbocharge a favorit

Ah, a man like me. Contrary to what you might think, given my forum name, I have not actually done this conversion yet. But I am going to do it. I'm currently still in the research stage and I'm hoping that this site may be of some assistance.

My original theory, and you may still be able to do this flipper, is to use the carb, turbo and intercooler from a Renault 5 GTT. Unfortunately, my proposed car is an M registered 1994 model (on the verge of being purchased) and so has tighter emission regs. to comply with and a cat - hence the carb won't cut it.

I have since decided that there is no reason why I cannot modify the current injection set up to be able to run a turbo. My understanding is that later Favorits and all Felicia 1300s have single point throttle body style injection systems. These effectively use a throttle body on the manifold which acts much like a carb and one or two short, fat injectors (in comparison with MPi injectors). These inject fuel fairly contantly and supply all the runners of the manifold and all cylinders. This is a wet manifold system rather than the normal dry manifold system which only has air in the manifold until very nearly at the cylinder head. On MPi cars which are converted to run a turbo a common mod is to link fuel pressure to manifold pressure using a special fuel pressure regulator. In this way, the fuel pressure increases with boost pressure and delivers correspondingly more fuel. This is apparently good for up to 10psi of boost. I am wondering, however, if this will work with a single point injection system. Anyone got any thoughts?

If it does work then it'll be quite an easy conversion, and with 8-10psi of boost I reckon over 110bhp will be easily achieveable with very easy mods.

One last question - the standard favorit has a 67bhp? high compression engine (9.7:1 CR?) so I'll need to reduce this. Does anyone know if any other engine has a head with a lower CR which will be a straight swap? Also, if there are low CR engines in the range, is the CR lower due to differences in the head or in the pistons?

Re: can i turbocharge a favorit

The Favorits badged as LXi, or GLXi have 54bhp. The models badged as LXiE or GLXiE have 67bhp. The 54 bhp[135] engine is the low compression engine, and the 67bhp[136] engine is obviously the higher compression type. The 135 has dished pistons, where as the 136 has flat top pistons. The cylinder heads for both types are identical.

Anyone seen my anorak?!!

Re: can i turbocharge a favorit

Do you know the respective Compression Ratios for the 135 and 136 type engines? Am I right in thinking the 136 has a CR of 9.7:1? If the 135 has a CR of anything less than 9:1 then I think I'll have to re-consider the car I actually buy as I should be able to turbo that with no compression lowering mods.

Any clues on the other stuff? Multi point injection on these engines ever? I might end up buying an older Favorit with a carb and doing the Renault 5 thing for simplicity. What was the last year they had a carb?

Also, is there any engine strength differences between the 135 and 136 engines? (e.g. better bottom end or anything).

Sorry - you might have to pop that anorak back on!

Re: can i turbocharge a favorit

i dont think there's any strength differences between the 135 and 136 fav engines. Although i think fav cranks are weaker than original skoda rapid 136 or 135 engine cranks...i think i saw that somewhere. They will be hard to find though.

Re: can i turbocharge a favorit

there is an mpi version of the favorit engine its in the felicia (felicia 1.3 is the same engine as favorit) u might be able to use the head.
it would make it more efficient lol

Re: can i turbocharge a favorit

I think Dave is right - the only difference between the 135 and 136 engines is the piston type. - He beat me to it!

It has been done before btw, as has a Cosworth V6 conversion

It is also possible to rebuild the 1.3 engine to 1.4 spec with things like V8 Rover valve springs, increased compression by shaving the head, lightened strengthened and ballanced pistons conrods, reprofiled cams, porting and polishing the head etc, and 140bhp is possibe. Imagine that with a turbo too! 170bhp lightweight Favorit anyone? However - piston rings would definitely be a weak link, lasting maybe only 10,000 miles at such high compression.

Maybe a MG Metro turbo would be a good match? Should be cheap as chips too, and all carbs IIRC.

Re: can i turbocharge a favorit

Nah, the turbo on a Metro was huge. Originally they bought a batch of turbos rejected by Lotus as too big for the Esprit turbo. So too big for a two litre, but ok to fit to a 1.3. Just because they were cheap.
You would end up with lag city. So slow to build boost you can get out check the turbo badges are still there. Then when it spools, you end up with so much power you need to limit boost heavily because it breaks gearboxes.

Seriously, for a mainstream junkyard turbo, what you really want for a 1.3 petrol is, something from a 1.9 TDi

Alternatively think about supercharging with an intercooler. Mini Cooper S blowers go cheap on Ebay, and you can get an adaptor to allow you run it into a standard throttle body instead of directly mounting to the top of the engine.

Without much modification, can a G60 engine fit in a favorit?

Re: can i turbocharge a favorit

Flipper,

Whilst it is true to say that pretty much any engine can be made to fit any vehicle (i've seen a Rover V8 in a mini driving the front wheels!), some conversions are always going to be harder than others.

The first question to ask yourself is "what sort of power do I want?". I would suggest that 115bhp or so in a Favorit with upgraded suspension and brakes would be more than sufficient to give 0-60 in sub 8 seconds performance.

By far the easiest way to get the necessary power on the cheap is to turbocharge it. If emission regs. allow where you are, or if your car is old enough to use a carb, why not just adapt the turbo and carb from a Renault 5 GTT to your engine? You'll need a high pressure fuel pump too. The original cast manifold can be adapted to mount the turbo with a thick plate. The cast manifold will retain heat better and be less prone to cracking so it's not a second rate part.

To get the compressions down without having to remove the engine, just take off the head and do a compression ratio check (using a burette etc. - see any engine tuning book) and then work out how thick a gasket you need to get the compression down to about 8:1. Then get a copper gasket made up to the correct thickness.

This is what I now propose to do but my only issue is finding a Favorit old enough to use a carb and no cat and also run on unleaded. My alternative is to get a Felicia MPi and adapt the injection with a Megasquirt ECU. Does anyone know the make of the Felicia MPi injection? Is it Bosch?

Re: can i turbocharge a favorit

thanks
alot for all ur help.
knowing that I'm just 17, im new to the whole car mod industry but i'm trying to get with it.
here in jamaica there are tons of fast cars( mitsubishi evo 1 to 9, impreza sti bmw m3...) so i want a car that can atleast give the honda civics a challenge.
the favorit i have was my fathers and he was opting to throw it away. becuz favorits aren't common here and they are not high in HP, nobody wwanted it. i decided that i was going to be unique and take up the challenge of upgrading the car.(exterior, interior and performance-wise)
thanx agen for u info and i'll try to modify my SKODA FAVORIT

Re: can i turbocharge a favorit

favturbo - all favorits run on unleaded just fine all ally headed 135 and 136 engines do. any favorit from 88-93 will be carb fed no cat and run unleaded. 93-96 on was the SPI favorit era.

Just to throw in some bits of performance infor for you guys.

For an easy extra 100cc the fabia 1.4 8valve is the same basic engine, uses the improved MPI cylinder head from the felicia, and a long strok crank short rod combination to get the extra 100cc from the original bore. The engine casting on this unit is much improved especially in the bearing \ crank areas. However there are some engineering bits to do with removing hydraulic lifters etc.

The felicia MPI head uses narrower valves stems and have less valve guide protrusion into the port area, and a ever slightly changed port shape. they are usefull however they have a single valve spring instead of the twin spring set up of earlier engines - one step forward one back.

The cylinder heads can have the inlet valves extened to just under 39mm if you increase the bor of the engine to 78mm using czech supplied liner kits.

theres a company called engitec who can supply built engines to the uk off the shelf, should be an easier and cheaper way to get 115hp than a turbo charger.

Things to be aware of - the favorit shell twists. Ive done a it to a few of them with hard driving, to take serious power you really need to seam weld the shell and have a good roll cage - one that mounts to the suspension turrets. dropping a 1.8t lump or something in is just asking for metal fatigue and a car that quickly bends to the point where you lose all handling.

as far as handling goes best suspension easily available is HP branded from czech. Worth [paying out the extra money to get the competition stuff instead of the road stuff.

Braking wise brembo do disks for the standard favorit brakes and EBC \greens stuff do pads, service the rear end properly and thats all the braking you could need.

DONT trust the goodridge braided brake hose kits - their data is wrong you need a 4 line kit, they often try to sell 3 line kits - these dont work.

The MPI felicia engine easily attained 90hp with basic exhaust airfilter and ecu remapping work. however it did require uprating the fuel pump and injectors as the original items didnt have enough spare capacity for the power hike.

Re: can i turbocharge a favorit

Why dont you try a engine builder for rally cars as a customer at my work
owns a ex skoda works felicia running 132hp at 8500rpm normally aspirated.

He takes it rallying and has beaten of some big powered evos, cossies ect ,

the last time at knockhill he came 16th overall and beat all evo entrants.

Out of 1300cc and 700kg weight, 131hp its certainly interesting

felicias had 1.3 spi to start with and then moved on to mpi. the 1.3mpi as i think someone said is good for 140bhp anyway.
