hello

just bought my first alfa today. its an x reg alfa 146 2l ti twin spark.

can anyone give me any info on the engine. done some searching on the internet but cant find the right answer.

anyway does this engine have a turbocharger on it or is it just a really quick accelerating engine?

cheers in advance

thanks

The twinspark engine isn't turbocharged in the 145/146 from the factory, but it is a peach of an engine.

It's a twin-cam four cylinder 16 valve engine with two spark plugs per cylinder versus the single plug per cylinder of conventional engines. The 2.0 has a balancer shaft to smooth out vibration, and most of the engines have a "phase variator" fitted, which is basically a widget fitted to the inlet cam that changes the valve timing to give better power when you floor it, and reasonable economy when your not (that's why it feels like someone's lit a saturn V rocket behind you when you go over 3k RPM). Known weaknesses include a tendency for the engine to use a little oil (check it WEEKLY, WITHOUT FAIL otherwise it'll be game over), cambelts must be changed at 36k (not the 72k alfa recommended) but other than that they're really rather good.

I'm sure someone else will be along shortly with more info, but welcome to the world of Alfas :D

Cambelt must be changed at 36k or 3 yrs; whichever comes sooner and to be brutally hones, I wouldn't let it go a mile over the interval due to the increasing number of engine fatalities.

Other know weakness is erratic idle and MAF (Mass Airflow Meter), do a search on here there are umpteen posts on these issues.

In the 145/6, gearing is short, suspension is "firm" to say the least and the high driving postion and quick steering rack make the car feel like it's doing 90 when i fact you're only doing 50.

Phase 1 engine (alloy top) was 150bhp, phase 2 (plastic top) is 155bhp which was/is based upon the old Lampredi unit used in both the Lancia and FIAT 16valves. Some engines do drink, none of my have though but best be safe and check it regularly, as noted earlier.

Regular oil changes are a must and don't use crap oil. Alot of us North East Alfa owners use Seleni 10w60 Racing as recommended by our local specialist, who sadly is no more.

The twin spark was replaced by the 165BHP JTS in the later 156's etc.

There are a couple of guys on here who are very knowledgeable and can no doubt give your detailed info.

Send me the chassis number and i'll tell you exactly when it was built, the colour engine variant and even trim level.

But now for the things to look for:

1: Lower wishbone bushes, worn bushes give you a knock and wandering direction, as they get worse the inside third of the tyre evaporates faster.

2: Diesel sound on start-up, if it clears after a few seconds then it's the variator starting to wear internally (yes, your car has one), if the noise stays you have a noisey tappet, a flush, oil and filter change normally quietens things down.

3: Cambelt, should be number 1 but I see you have another thread for it already, they are not the problem, it's the plastic tensioner, the belts will go over 90K miles, mine is proof, but I have a metal tensioner as is the only one sold nowadays, the recall did not include 145/146/155s so don't rely on a dealer to tell you of the new timings for change, 3 years or 36K whichever is soonest.

4: Rear swing arm bearings, these are starting to become an issue, there is a kit for replacing them, but to get the bolts out you have to be lucky or well equiped.

5: Front top mount bearings, when these go every bump on the road will sound like a bomb is going off in your footwell, a ***** of a job and not one for the faint hearted mechanic.

6: Drop links, again they knock on the bumps, but you can inspect these simply, if the rubber bushes (x4) are split, replace them, they're only pennies.

7: Jerky wipers, a sign that wiper motor failure is iminent, pick up a good'un on ebay for 50 sheets.

8: Side light bulbs, I don't know why but the 145 and 146 eat side light and number plate bulbs, I got narked with this fact and just fitted LEDs, job jobbed and not changed a bulb for 3 years.

9: Airbag light, damn those underseat cables, disconnect the battery, bend the pins in the plugs slightly and reset the light (you need diagnostics for that).

10: Clutch slave cylinder, getting difficult to select gear? Wet gearbox? Low brake fluid level? Pedal stays on the floor? You guessed it.

146 Ti, Engine: AR32301 (CF2) 2.0 TS 16V (155 BHP), Interior: Anthracite Cloth, Built Jul 2000, Build #: 00225439 (2 before mine so yours was the 7th last), Engine #: 2077605.

In all yours is one of the few 146 Ti's that can use Alfadiag thnaks to the use of the M1.5.5 ECU in it.

Cambelt is half days labour at a garage (4 hours) expect to pay around £400 for variator, 3 belts, 3 tensioner and 2 idlers, but for that price I'd also throw in a water pump (though they are very reliable in the twinny) and an ECU read, as well as sorting other niff naff probs that dont need parts.

Justin (from BMC) can change the belts in just over an hour if he's not interupted - no wonder Alfa charge so much.

I would imagine about £380+ for belt, aux and variator change - some garages have a reluctance to tackle the job.
