(G) Best options for torque gains?

With £500 what's the best way to get more torque, primarily, and power out of a Mk1 Sei? I've got a CSC exhaust in the post, consider it installed already, & the car already has a green cotton filter. My list is (I'm sure this lot will break the £500 limit but hey) -
* GSR induction kit
* 40mm Throttle Body
* C&B 268 cam (or something equivalent)
* Mckcrich chip

If you can afford to run it (maybe you have a friendly dentist!) a NOX kit!

Otherwise -- completely untested -- Mckrich, Pug/Citroen 36mm tb (less than £20 from a scrapper), DIY induction system.

See how that lot goes and think -- with the vast savings you've made -- about some head work before the cam.

I'd go brakes and suspension instead, should be able to get a chip too for £500.

For about £400-£500 you can get a low milage 1.2 16V. Of course the extra lil bits may take it higher, but you get nice big gains all around.

I have started a fund recently for this very job

/edit, sorry i meant for mk2 where i hope you can use the same ecu. Costs will be higher than what i said if you need a new ECU etc.

Fingers99, I'm more wanting things that are a known quantity, I'm not wanting to revisit further down the road.

Liam, I've got items in the works for brakes and suspension, I just want to bolster the engine a little.

kritip, I've got the bottom end of a 1242 8v (60 I think, can't remember), so as long as the 1108 head will bolt on that's my 1242cc. I'm more wanting torque than power.

OK. But there really are no known (objectively) quantities here at the sub £500 level!

Here's my logic:

A NOX kit will improve torque.

Larger capacity will improve torque.

The Mckritch will make the car nicer to drive. A bigger throttle body at a bargain price will help -- a 40mm body may be too big without further modifications and, generally, large increases in TB help top end at the price of bottom end.

A decent induction system will help, but you already have a filter. Make your own. It's pretty well established that the length of the system helps torque but even more important is that it recieves a good supply of cold air.

Fitting a lumpier, longer duration cam won't help torque and is a step you want to take only after gas flowing the head: that extra gas needs to be able to move.

Well, Standard 1.1 Cinquecento engine, 86 Nm at 3250rpm, 60 Selecta 1.2 engine 98 Nm at 3000 RPM, Punto 85 16V engine 113 Nm at 4500 rpm

Volvo 2.3 940 SE turbo 264 Nm at 3420 rmp, therefore you should spend 500 quid on a Volvo.

are you trying to copy my car spec?

GSR £99
40mm TB £130
C&B 268 £240
Mckritch £52

So a wee bit over budget

With the SS manifold and CSC cat back mine is very drivable if I were you start with the Mckritch then GSR then TB then the C&B if you still want more after that all these bits would transplant to a 1242

BTW if you go the NOS route that would be about £500 for the kit then £30Per 5lb refill but if you do go that way let me know how to do it! had a press of the NOS button in a hot Integra Type R I was having a go in yesterday and I'm Hooked

Don't forget that adding a GSR to an 1108 gives you the same torque as a 1242

allanhelen, no but it looks to be a nice spec for a cento. How does it compare to a standard Cinq sporting at 2500 to 4000 rpm?

Rob from Clubcento has / had NOS on his.

I don't know its a long time since I have driven a std one I am happy with the way my car goes now there is no fat spot and it pulls like a train, it's quite effortless compared to what I recall it being like.

One of the reasons I fitted the bigger brakes was that often it catches people out. They see a small car and don't expect it to be going as fast or accelerating as quickly as it actually is, so they pull out in front of you so don't forget the stoppy stuff as well when you are doing things, uprated discs and pads upfront and a quick service of the rears if nothing else.

As I said go for the GSR, TB then Mckrich first. IIRC the TB gave the single biggest noticable improvement.

You do know that once you start messing with these things you can't stop don't you? I was only looking for a cure for the flat spot and things just seem to have got a bit out of hand

This years bonus looks like it won't be big enough to fund it, so a pipe dream for now

Fit a Diesel?

On Second thoughts, probably more than £500, unless you can find a second hand tractor.

Tipo TD SX

I see I was right about the tractor then.

Okay I'm not looking to change my car, I don't want to do a conversion unless it's from parts I already have. I'm just looking to get it a little more effortless in the mid-range and a bit more power
