You'll certainly need it, I just wasn't sure whether favorit needed them, as it has a slightly different springs compared to Felicia. Pushing the spring a bit more didn't help? Did you put the cups in the right order? They are slightly different.

The old mounts are just deformed, this is how they should look like. Did you need a spring compressor to remove them?

Unfortunately, Forman doesn't have mountings for ARBs. You'd need to fit front axle subframe (which has different mounting points) and arms and rear axle from Felicia.

Favorit was a light car, Felicia is some 100-200kg heavier.. My estate was like a boat, ARB was definitely positive. I agree, that modern cars with to stiff ARB can be quite nervous, but that's not the case of the Felly. You are onto something with the cmaber - Felly has pretty low caster angle, so many people racing them are looking for various methods to increase it

That might be possible, since caddy had a 1.6 engine, which I've never seen in the Pickup - with exception of the Fun. I didn't find any official info about which variant was used on which model...

I also added an ARB on my Felicia (with otherwise stock suspension) - the handling improved, especially with R14 wheels, the car felt stiffer and rolled less - but it wasn't too stiff, like more modern cars tent to be. I later added a rear ARB to keep things balanced (my estate didn't have it from the factory)

IIRC, 22mm is exclusive to Fun and it'll be hard to find. All other models had 20mm. It can be found on all 1.6/1.9 Felicias or 1.3 with ABS.

All these engines had same head and deck shape. The difference happened when they switched from cast-iron (130) to aluminium head (135/6) - different bolt pattern and channel layout resulted in different shape of the head, but the block required only minimal changes in areas around the head bolts. Water/pushrod passages don't need as tight sealing and exact shape and cylinder liners and oil passages fit perfectly.

There's another variant, although I've never seen it done: Felicia seats with side airbags have backrest frame from Octavia MK1. That means, you could swap foam and upholstery from Octavia (or other car using the same frame). Bottom part of the seat could be more problematic, but it might fit after minor modifications

https://youtu.be/jbteh1MAgLI Here's video of fitting MK5 Golf seats - which should be similar to MK2 TT. They fit to mounts, but end up too high, which is why they had to mod the floor. MK1 TT had different mounting, with rails integrated in the floor. That's require somehow welding Felicia rails onto the TT seat.

I think they mean storage box in the cargo area. I haven't found any info, but I found a picture of a removed box, which suggests it's glued

Wow, that's actually more primitive than ones in Felicia, which had basic automation. They also had some "bonus" functions not wired in the factory installation - as motor units were re-used from VW T4 - like secondary switch or disable signal (so they can be adapted as rear windows). Unfortunately, the outside control wasn't amongst the functions - although, there are two pins with an unknown function.

Wow, it's serious downgrade then, because that function was present in MK1 and MK2. Does it at least have one-touch rollup/rolldown? Yes, Felicia's Windows do require some extra wiring, but for example mirror switch can use the same power input as windows. And windows are at least smart enough to have one touch rolling and do work for some time after ignition is switched off.

You don't need to turn the ignition on to move windows on the Fabia. All windows can be rolled up/down from the outside by holding the key in lock/unlock position. As long as the microswitch in the lock works 😀 As long as the motor's have automatic functions to roll up/down, it's definitely worth it.

Yes, it is a rebranded Inca, but Inca is derived from Ibiza Up to the B-pillar, they're nearly identical, just like Felicia/Pickup

It's a coolant drain plug.

You'd need to replace the rear beam. 93 favorit and Felicia had different mounting for the stub axles to fit MK3 golf brakes.

Caddy pickup or caddy van? The Pickup is just rebranded Felicia, so it'll fit, but the Van is based on Seat Ibiza, so the mechanism Is different.

Pretty much yes, 136 have flat pistons, while 135 have an oval recess. There was a huge variety in camshafts and heads, IIRC, the 136B had the largest duration, while the 136M (Felicia) had the best head design. The 136X also had a different ignition timing to achieve a bit higher power. Maybe I could find some more information. Yes, the head design is the same, as the 135 has been derived from the 136. I think that were attempts to chip tune the ECU, but it requires hardware mods. Maybe it'd be easier to get carburettor instead. Turbo was done on the MPI engines, but it's a lot of work, which requires custom software and ideally a Fabia block.

There should be a sticker in the engine bay. Felicia can have 3 variants of AC, only one is documented in the workshop manual - can you post a photo?

I don't think there'd be any gain, as the hole provide enough air for the larger 1.6 and 1.9 rads. Back to the topic, IIRC, the grill and chrome frame on the facelift model is identical to the Octavia MK1, so there might be some options. However, mounting around the chrome frame is different on Felicia.

Yep, it extends more in the bottom portion and helps direct air to the radiator

Early Favorits had just small slit, I'm not sure whether it did anything to cooling.. however, I've read numerous topics about Felicia front swap, where removal of the scoop behind the bumper cover lead to reduced cooling performance. Yep, and it's same on the other brands, like my SEAT with considerable smaller grill:

Felicia/Favorit was designed to supply cooling air through the bumper, the grill is mostly cosmetic - 1990-1992 Favorits had no grill at all. I've even seen some flow simulations that showed that grill can actually take some air away from the radiator, due to low pressure area on the bonnet edge ( probably reason why the newer Škodas have top portion of the grill blocked out)

256mm conversion is well documented. I think that some variants of Mondeo had the same calipers. But it doesn't work with 13 inch wheels. Some variants of Sierra (non-ABS I think), had 238mm discs and calipers with 54mm piston, which should be the same as Felicia. But I don't know which discs can be used with that conversion
