General Anyone for 2.4 Engine Tuning??

[SchooweeNick]

I'm at present trying to help Pete (oldschool / GSR) with anything he needs to seriously look into some proper engine mods i.e. Porting, polishing, gas flowing, camshaft's and possibly further..
We're talking de-cat/ sport cat's etc. Silicone coolant pipe's
However some of this work is going to depend on how many people are SERIOUSLY interested in it.
Would like to get an idea how serious anybody else is..

I know I am desperate to bring out the potential in mine... :devil:

Anyone else???

Hi mate, I would be up for it, but im a little aprehensive about the costs, any idea what sort of costs we are looking at?
As mine is an 02' abarth so its not worth that much, and I would'nt want to spend silly money.

My car is always available as its parked up at home, I only use it once a week at the moment.

Thanks

Im interested but as i still have warrenty which is a good thing with fiat i wouldn't want to do any internal mods until thats expired.

Stilo GP:devil:

 

[Cridders]

yeah mate would be interested in that. looked at doing an engine conversion using the fiat coupe turbo engine but cant quite afford it at the mo. If the price is good i would do it what bhp are looking at running? And where did you get your brake conversion done?

Would simply supercharging not be the easiest answer for a definate 250bhp? Only problem is if Novitec are the only company doing one? Because if they insist on fitting it its no use to us in the uk/irl. A friend fitted one (not Novitec) to his Golf VR6 in 3.5 hours. It was that easy. He did this about three years ago with no problems to date.

It is so frustrating as the Abarth 2.4 engine should make at least 200bhp in standard guise. Recently I got roasted by a Starlet glanza turbo @ 60mph. Though he accelerated soooo quick at this speed he had to have NOS or something.

Otherwise i'm interested in the de-cat if possible?

Fair play to you both doing the ground work for some power mods:worship:

BOL

Yea i wanna a piece too 55.
The Nov supercharger uses two small chargers for some reason but will have more drag than a bigger superc plus 2small ones take up more space too.

Hello... i'm from the Netherlands and i have a 200bhp Stilo Abarth. Things i did to achieve this:
- Modified Engine management
- Modified Selespeed (Higher rev limit)
- Carbon airbox (with air scoop in bumper)
- Camshafts
- Larger exhaust system (front to rear, no cats at all)
- Denso Spark plugs

This set me back a whopping € 4500,-

I've been looking for more horsepower but there doesn't seem to be a easy besides a compressor. One guy here in Holland had a Novitec compressor fitted to his Abarth but he had it removed because of all the trouble. It broke down every single month. The last time it even blew up his intake manifold because of a backfire issue. I believe that Novitec stopped making these kits for the Abarth because of all the trouble.

More horsepower would be possible but you will have to spend a hell of a lot of money

That seems extremely low output for the mods you've done!!
And at huge cost's!!
I'll keep you updated on the progress then...
I was speaking to oldschool today about how far I wanna take it and at the mo we're looking at porting and polishing (maybe angled valve seats) not sure about cam's yet.. I'll get pete to post approximate prices and info as I'm really not sure..
Plus I'm hoping to get rolling roaded before to give us an idea of how it goes... pete?

I would be supprised if u would get more horsepower out of this block without major steps like flowing the cylinder head, modifying the valves and so on.

PS... i'm talking about euro's not pounds so it ain't that much. € 4500 equals about 3000 pounds. All components are top of the bill... the exhaust system for instance is completely custom build Stainless Steel including the exhaust manifold

 

[Stu DemonD]

I still think £3000 is a lot, ONLY to get to 200bhp - I would expect more.

I got to 190ish relatively cheap.

I am quite positive to get more than 200bhp out of this engine with less than £ 3,000. The 2.4 is an excellent power plant to start with. Porting and flowing is a comperatively straight forward job.

The weakest point is the exhaust and within the exhaust the cat. The manifold is quite good, which is the most expensive part other than the cat.

To exceed the 200bhp barrier it shouldn't take more than £1,500.

:slayer: Yeah!!!!I want some.
Baser who did the engine work? AutoDelta can get a Alfa 1.6TS 120hp engine to 200hp for the same money,180 for less.
A 147GTA (3.2 V6)250 as standard ups to 350 or 400hp if youve got a decent wallet.
Both Alfas and Fiats the 2.4 engine are tough little engines.I have faith in pete he'll get 220 maybe 250 with more hard work-Poor pete.

Ok tell me what did u change and what did it cost. Can u show me the dyno printout?

Mine was tuned by Madeno Racing. These guys race with Alfa's and this year also with Seat. They know what they are doing and i've spoken to mutiple tuners and they all come up with the same story. "The 2.4 engine is very difficult to tune"

Had a remap done via Angel, together with a BMC CDA fitted - cost well under £500 IIRC. No RR figures though, but it feels so much different, and I am a happy customer

Obviously the 2.4 engine isn't the easiest engine to tune. To start with the design of a five cylinder manifold is one of the most difficult to do.

Maybe this is besides the point. Still I dare to ask the question. Where is the challenge when everything is dead easy. We are going to address the problems and will get successful. The engine has got plenty of potential and is just waiting to have it unlocked.

Anyway, between difficult and impossible a whole world can be placed.

Induction is a crucial thing to get right and to start with a carbon airbox is only second best. And just in case uyou want to oppose this statement. I have advised a number of race teams to revise their intakes to get more power out They also knew what race engineering is about.

No dyno... so how do you know u have 190 bhp? because the tuner told u so? come on... wake up

My engine had exactly 170bhp when i dyno'ed it for the first time. But we had multiple Abarths on the dyno and the lowest started of with only 163bhp and the highest was 172bhp

I had the same at first.. a remap and a BMC CDA.. i dyno'ed before and after everytime i changed something.

BMC CDA does about 6 bhp (total 176bhp)
Remap gained me 9 bhp (total 185bhp)
camshafts + exhaust 15bhp (total 200bhp)

I have swapped the BMC airbox for a real carbon airbox with the intake in the bumper so it forces air into it. I noticed a gain but i haven't dyno'ed it yet (going to soon though). I think i'm somewhere in between 205 and 210bhp now.. but only the dyno can tell.

Anyway i'm hoping u guys can come up with something. I know there is a little secret in the engine waiting to be found unlocking it's full potential. Keep up the good work
And remember only dyno bhp's count.

No dyno...

Is your abarth selespeed? How did you manage to measure it on the dyno?
I was only able to get the measurement on the wheels (cause of selespeed), and it was 161 .

btw is http://www.madeno.nl/ where you did yours? I am interested in more info on selespeed remap, how it is done and what it does exactly.

I am wide awake, plus I trust Nige at Angel and I did say about 190bhp - I am not fussed if it is 180 or 190, at the end of the day, the car feels better, and it is not ME who has forked out over £3000 - maybe you need to wake up

I am interested about this dyno process on a selespeed though :chin:

Measuring a Selespeed on a dyno is officially not possible indeed, because u can't measure the loss in the transmission. But since the selespeed is nothing more than a robotized manual transmission it's quite safe to say that it has about 15% loss in it's transmission just like a normal manual gearbox. We even measured the loss of a Abarth with a manual gearbox and it had a loss of 14,8%.
So at the Dutch Stilo Club we agreed on 15% so we can compare easily.

The Selespeed remap is nothing special to be honest. The only thing it does is set the RPM limit a bit higher. Without the remap it will shift automatically at around 6400 rpm. With this remap it will shift at 7200 rpm. This way you have a little advantage in sprints

Baser what grade of fuel have/do you used?that may make a difference Also have these options been lightly done to save the engine life aswell to cope with different types of fuel you may use?

Modding the internals of an engine is an arse but more razzer-mer-dazz.
5cyl engines are a weird odd engines,rather than the usual 4pot or 6arrangement.The 5cyls arrangement of a odd(extra) cyl does make things a little harder,only afew makers had and have them now,Merc(that naff pointless poor persons merc car i cant remember,the small coupe comp),volvo(new)+Ford ST which is the same unit,old audi Quattro just to list the pop.

The other (volvo/ford) makers seem to put a light pressure turbo on theirs but that doesnt mean they have the same internals,the fiats rev a little futher being naturally inducted to produce the power,just to slap a light pressure charger may need internal strengthening or it may go bang over time.

If people wanted/needed charging,Super charging would be the best option as supers generally are kinder on the engine due to its softer(if you set it up that way)continous progessive nature even thou it takes the engine to run it its generally better.
But my personal feeling of wot id like is a nasty gruffer 147GTA or race style engine,hard rough idle,all full force at hight revs.
Its a shame that we dont know who made or designed this engine for fiat.

Rolling roads are only guides not to be taken as gospel.
