Just to give you guys an idea of what I'm talking about:

Translation:- What a joy to find another lover of the Rapids! I have the sedan version, but honestly I like the hatchback better than you have. Too bad they never offered it here in Mexico (because mine is sold by SEAT under the name "Toledo"). If only I hadn't bought it anyway (although I'm not really complaining about the extra space in the trunk). Te ofrezco una disculpa. No se por que entendí que habías cambiado el motor completo (supongo que por lo que mencionas de haber tomando el turbo del motor de 1.4 de 150 caballos)...

Can a moderator please delete my last post? I misread it. I thought Pedro had swapped te entire engine...

¡Que alegría encontrar otro amante de los Rapids! Yo tengo la versión sedán, pero sinceramente me gusta más el hatchback que tú tienes. Lástima que aquí en México nunca lo ofrecieron (porque el mio lo vende SEAT bajo la denominación "Toledo"). Si no me lo hubiese comprado igual (aunque realmente no me quejo del espacio extra en el maletero). Se ve que le has invertido mucho tiempo y dedicación a tu coche y te felicito por ello. Yo el mio, desde que lo compré, siempre lo he visto como un Audi "disfrazado": porque literalmente todo lo que realmente importa es de esa calidad. Recientemente he visto un A1 de primera generación y me quedé asombrado: el reposamanos delantero es igualito. Y siempre me ha asombrado que pese a que lo han criticado siempre por sus acabados austeros, en lo que realmente importa, que es la calidad de ensamble y el equipamiento, siempre tuvo de sobra para su precio. No se allá en Chile pero aquí son pocos los coches que traen detalles como la puertita detrás del descansabrazos trasero (la que conecta con el maletero). El mio tiene también el asiento del pasajero ajustable en altura (que es raro ver incluso en coches más caros), portamapas en ambos asientos, cinturones de seguridad ajustables en altura, manijas para los pasajeros en las 4 esquinas, espacio para llevar anteojos... no se, supongo que esta de más que yo te diga todo esto, teniendo tú uno, pero es que no termino de entender que la gente no entienda que era una verdadera ganga para el cochazo que es (en España en particular, hablan muy mal de él, supongo porque es un coche tan práctico, que lo veían mucho como Taxi. Y además porque el Toledo original era derivado del León y éste deriva más bien del Fabia; siempre dicen que es más un Córdoba). En lo único que se ha quedado corto es, en mi opinión, la parte de la potencia. No es que le falte, en sentido estricto, para el tipo de uso para el que fue diseñado, pero el motor que yo tengo de 1.2 de 110 caballos resiente mucho cosas como usar el aire acondicionado e ir con 5 pasajeros en carretera. Quisiera actualizarlo obviamente, pero como seguramente lo entenderás, por mucho que quisiera ponerle al mio todas las cosillas que tú le has puesto tú al tuyo, realmente lo uso en tono familiar, y pues tengo que ser un poco conservador al respecto. Es una excelente plataforma para irle poniendo cosillas y vale la pena el esfuerzo. Aquí vendían el Golf y Todavía venden el Jetta, pero es que no se me antoja tener un coche mucho más grande y pesado sólo para tener más motor. Así es que igual que tú, yo lo que quiero es un coche más contenido en dimensiones y peso, pero con la misma potencia. Básicamente, quisiera ponerle el motor 1.4 de 150 caballos y la caja de cambios que sigue (tengo la de 200 Nm manual). Lo mantendría básicamente de serie salvo por el cambio de motor y transmisión, principalmente para no tener problemas legales y para facilitar el mantenimiento. (Igual y consideraría cambiar los frenos también. El mio trae 288mm ventilado al frente y 232mm sólido atrás con las ruedas más ligeras que encontré: Avus del Golf IV de 15". Pero creo que el freno de 312mm requiere ruedas de 16". ). ¿Crees que me pudieras asesorar? Me interesan TODOS los detalles que me puedas dar al respecto, especialmente si te ha surgido alguna dificultad y cómo la has resuelto. Por ejemplo: ¿con qué motor y transmisión venía tu coche de fábrica y cuáles monta ahora? Me refiero a los códigos de motor y transmisión. Dónde has conseguido las piezas y cuánto te ha costado... Muchas gracias de antemano y felicitaciones nuevamente. Saludos desde México. P. D. Mi coche esta de serie, salvo por algunas modificaciones muy sencillas que todavía no completo. Compré un interruptor de una Arona y un sensor solar para agregarle luces automáticas (limpiador automático no me interesa, ni retrovisor electrocrómico, sino hubiese cambiado todo junto). También compré el apoyacabezas central porque el mio sólo traía los laterales. No esta completo porque sólo encontré uno de los insertos de plástico que van en el asiento. También quiero ponerle aire acondicionado automático pero según he leído es bastante complicado. O la pantalla más grande...)

That's nice and encouraging. Care to share more details? What engine did you have? Which engine did you install? Where did you get it? How much did it cost? Did you change the transmission too? What issues did you have to overcome?

This is the car I would buy if it was sold here (1.5 and manual). I'm envious. It seems like you won't be able to get a manual transmission on a decently powered car soon.

It seems like I never replied to you @Carlston I was hoping to get a set of Pepperpots, but I never found any, so I ended up buying a set of new MK4 Avus 15" 6J wheels I found on sale. I fitted the stock size on them (185/60R15 Michelin Energy XM2) and went to Aliexpress for a set of generic hub caps, since the original ones have the old blue and white logo and look kind of odd. They didn't come that way, though. I had to buy the loose silver and black emblems and glue them. I replaced all five wheels, including the spare (I now have a full size spare, so no 80 Km/h limitation). Ride quality is fine, not great, because I'm afraid to hit some pothole and damage the rim. That's why I've been using 36 PSI on front and 34 PSI on the back. Steering is quite nice and I get very good mileage (I've seen as low as 4.xl/100 Km). Alloy wheels are definitely stronger than steelies. It looks really clean to me...

Sure, we all want lots of power. But for me, to upgrade my car (Rapid) to match the same amount of power of the larger VAG cars (Jetta / Golf / Octavia) would be more than enough because the other goal of mine is to do so without making maintenance for the vehicle too complicated (such as attempting to retrofit an EA888 engine). I want to be able to service my car with stock parts, just borrowed from other models. According to your input, in order to hit around 150 HP of power, I have three options: 1) Keep the CJZD 1.2 engine, and work from there. 2) Upgrade to the CZCA/B 1.4 125 HP block, and work from there. 3) Swap everything for a CZDA/B 1.4 150 HP version. Option 1: Keeping the existing engine From what others report, it seems possible to just upgrade the turbo and do a custom map, but it's complicated at the moment, because there is some incompatibility between the readily available turbo units and the amount of displacement provided by the engine. Summarized, they simply doesn't blow enough pressure at low RPMs to spin up the turbine, and then supplies way too much pressure at higher RPMs. A variable geometry turbo would probably solve this issue, and the first idea that comes to mind is to transplant the turbo from the new 1.5 TSI. However, there i still a mismatch of displacement (a larger one, in fact) and proper operation is not warranted. However, there is an alternative. The standard turbo design is modular and it seems like there is no necessity to alter either the turbine cartridge or the exhaust side of the casing. It should suffice, at least in theory, to built a custom intake casing with the variable flaps. Since this doesn't spin like the turbine, it doesn't require the same amount of accuracy, and it doesn't use exotic materials such as inconel. Therefore, it should be possible to build such a thing in a standard mechanical shop. Conclusion: the least expensive path, but complicated due to reliance on custom parts, so it kind of defeats the goal of keeping things stock. Option 2: Upgrade to the 1.4 125HP bloc and work from there What happens if you bolt a large standard turbo into a CZC? I guess you won't experience the low RPM lack of power others have reported, yet boost would be sustained longer than with the medium standard turbo, for some extra power? The way I see, this is the path to take if you want to avoid messing with the electronics, since you don't have to figure out how to handle extra features of the 150HP version with the existing ECU. It should require a custom map, though. Conclusion: It is way more expensive and complicated to swap the entire bloc, and also more wasteful. What do you do with the old bloc? Results, however, are kind of warranted with this option and I can see why @TheFozzy opted for this. Option 3: Swap everything for the 1.4 150HP With this option you're essentially copying the entire drive train of a different car. Issues are unlikely, since all the parts are already meant to work that way. But this is the most expensive option of all. Will an ECU from the 1.4 150HP engine play well with the rest of the electronics of the car? Who knows. General stuff: Can features like the regulated oil pump or the variable exhaust timing be retrofitted into the 1.2? Not that it's too important to do so, but it would be nice to explore that possibility, because I'm pretty sure it would have an overall positive effect on the engine (if it becomes more efficient, it has to burn less fuel to produce the same amount of power, and that not only increases your mileage, but also reduces the wear and the possibility of cooling issues). I've noticed that CZC (125HP) has a higher compression ratio than the CZD (150HP). And both CJZ (110HP) and CZC engines use the same type of Lamba probes, but the CZD user a different type. Are there other differences that I'm missing? P. S. I'm checking data from here: https://www.upownersclub.co.uk/attachments/ssp-511_the_new_ea211_petrol_engine_family-pdf.7106/

Oh, I got you. It's just that I can't believe they just lied there. It's not just a marketing gimmick; this is downright fraud. You can't put a 192 HP engine in a car and rate the car at 192HP. You have to rate the car according to what it actually produces. I wonder how does VAG gets away with this...

1.5 TSI Variable Geometry Turbo. Shouldn't be too complicated to adapt it mechanically. To have the electronics handle the extra actuator properly, probably much more complicated, but at least in theory, possible.

Unless I'm missing something here, this simply can't be true. Power is a factor of torque x angular displacement. So if you lower the torque, you must raise the RPMs, in order to have the same power output (this is, in essence, what a transmission does: exchange, both up and down, torque and RPMs). It's basic Physics... I've investigated and the manual 2015 Polo GTI uses the MQ350 transmission. There must be a DSG equivalent with a 350 Nm rating installed in the automatic version.

Well, I just spent the whole Sunday re-reading the thread and doing some research because I'm really into this. And I think it just paid off, because I picked up some bits that I missed at first. The most important of all: do 1.2 and 1.4 engines share the same basic bloc design? I remember someone mentioning that they do, and that they are just bored with larger cylinders. If so, they must have the same bore / cylinder spacing, and if that's true -and contrary to common sense-, then the 1.2 engine is stronger by virtue of having more metal on it. It appears to be the case, as both have 82 mm spacing, despite having different bore diameter (71 vs 74.5 mm). Sure, the displacement is lower, which limits the amount of power you can extract from it at the upper end of spectrum, but in the end, this is not a naturally aspirated engine, but forced induction, so it can burn as much fuel as we want it to, as long as it has enough oxygen for it, and it doesn't melt in the process... None of that concerns us folks who are just looking for modest power gains with minimal modifications (basically, the goal of this topic), like in the 140-160HP range. But it does, however, open the possibility (at least in theory) for some interesting future modifications, such as swapping the head to add exhaust valve variable timing, which appears to be only present in the 150 HP variant of the 1.4 TSI, and not in the 125HP version, or the 1.2. And of course, installing a beefier clutch and transmission. For now, I think all the problems mentioned here could be solved by a variable geometry turbo, as someone suggested earlier. Shouldn't our efforts focus on that?

Let's do some common sense analysis: Most people don't care about what's under the hood of their car, specially when it comes to transmissions. So why do they put an MQ200 transmission on the 125HP version of the 1.4 TSI and the MQ250 on the 150HP version, the later being more expensive? There must be a technical reason for it. I doubt people at VAG are stupid and they don't know that they could save money by installing the MQ200 across the entire range. One possibility I see is that MQ200 is destined for small cars while the MQ250 for medium cars, so the axles are different (wheel bolt pattern on small cars is 5x100 and 5x112 for medium and beyond). Maybe there is only one version of each, so you have to use the MQ200 if you want the 5x100 bolt pattern, and MQ250 if you want 5x112. However, this is obviously not true, having some cars like the Golf, with both MQ200 transmissions and 5x112 axles. The other possibility I see is the way the safety margin is designed. The rating of a transmission is not so much for continuous usage, but for catastrophic conditions. Like you push the clutch, engage first gear, forget you're pressing the clutch and release it suddenly. If you have an MQ200 transmission, and an engine with up to 200 Nm, such as the stock 1.2 TSI, it will just stall, and nothing would break. Same for the MQ250: up to 250 Nm, like with the 150 HP 1.4 TSI, a sudden clutch slam will result in nothing breaking and only stalling. But maybe -just maybe- if you install an MQ200 (rated for 200 Nm) with a 150 HP 1.4 TSI (rated for 250 Nm), if you accidentally slam the clutch, the engine will not stall, and something in the transmission is going to break.

That's the first thing I did when I bought my car. Some guy bought my wheels (16") and tyres and put them into an Ibiza MK5. He gave me his (15"), which I still have. Too bad the MQB wheels are tighter and don't clear the brakes without a spacer. I just have them in storage... I ended up replacing the steelies I had originally fitted with a set of Golf IV Avus wheels. From my research, they are the lightest 15" wheels that fit properly, other than the Audi forged Pepperpots... I was about to buy a set, but they sold and I've been unable to get more.

I think you're wrong here. The Rapid uses a lot of MQB parts, but the platform itself is PQ26+ I think. There are obvious differences, like wheel specifications (I've got a set of alloy wheels from an Ibiza MK5 and they don't clear the brake calipers without a spacer). The Rapid I have (a rebranded SEAT Toledo) uses exactly the same wheels as the Golf IV. I mean, literally (I've got a set of 15" Avus wheels on mine). Brakes are also the same (288mm ventilated front, 232mm solid back). Now that my car is about to hit 6 years old, and out of warranty, but in good shape (I've only put 50,000 Km on it yet) I've been thinking about the possibility of upgrading it. I was thinking about buying a nicer new car and keep this as beater, but the market is so depressing right now. There are literally no fun cars anymore and by fun I mean small, high powered and manual transmission (I can buy the WRX here but 1) It's not small and 2) it's a lot of money and I'm sure my another half would go ballistic...). They don't sell the Fiesta ST here, which is my idea of a nice car. I just read the whole damn thread and I wonder why nobody has brought up the topic of the transmission torque limit? The 1.2 TSI is always paired with the MQ200 (if manual), which is rated to 200 Nm (I know the DSG version is rated to 250 Nm). How safe is it to run 250+ Nm on an MQ200? Given that I can't simply buy what I'm looking for, and assuming money is not an issue, how likely do you think it is to swap both the transmission and engine with a stock 150 HP 1.4 TSI and MQ250? They did sell this model with the 125HP version of the 1.4 TSI and the DQ200 DSG transmission, so at least engine mounts and the like can be sourced easily. I'm not really looking for über power, just a reliable car that has a decent amount of power for the size. Damn Skoda for never releasing this combination... And damn the whole industry for not making more fun, manual transmission liftbacks. P. S. I'm exaggerating. They do make the manual Integra, but in their ****ty wisdom, it's not going to be offered here either.
