Lightened engine internals

Im looking at replacing some of the OE parts of my 2.0 TS engine and box (147 Selespeed) with lighter parts. Getting serious bhp out of the TS is pointless and expensive but making it more responsive and freer revving would make it a completely different car to drive.

So far, work on the to do list is removal of the balancer belt, lightened flywheel, lightened crank aux pulley, induction, exhaust and finally a remap.

Is there anything else that would see a significant benefit? Obviously I could replace everything with uprated/lightened part, but as always cost is an issue. What about the crankshaft?

I already have eibach suspension, uprated pads and braided hoses, so it handles and stop pretty well.

I'd put fast road cams in... and supersprint it.

Re: Lightened engine internals

I think I would just go for a turbo kit. Novitec do one and I'm sure Autodelta probably have something off the shelf. That would be my first choice.

I did for a while. Got a couple of Alfa's now. They say "you always come back" and I'm no exception!

As much as I appreciate the replies, if I wanted to spend £4k plus on a turbo or supercharger, I would. Or Id just buy a GTA. But I didnt ask that. I asked about lightened internals?

Re: Lightened engine internals

since a fancy crank would cost a fortune, and involve what is effectivly an engine rebuild to fit, £4k shouldnt seem like that big a figure.


imo of course.

Re: Lightened engine internals

take the crank out and have it balanced and lightened, cost about 150 quid to do that

Re: Lightened engine internals

have to do it myself and he flywheel

if you have a smaller race clutch fitted you can reduce the mass further on the flywheel

As E.A says, the list is allmost endless...

Re: Lightened engine internals

If you go for a lightened flywheel, make sure it's from someone reputable. Don't want it letting go on you.....

Re: Lightened engine internals

I haven't done much research yet, but if all else fails, I'll go for the one Autodelta are offering.

Carry on my friend, the more the merrier as far as Im concerned. If you get yours done before me, you can let me know what you think.

A company in Singapore (156 lighten crank) will provide a lightened crank aux pulley cheaply (under £80 delivered) and it adds up to 8bhp and 10nm of torque alone (thats according to their dynographs mind you). Simple to fit too. (This info came courtesy of Aziraphale).

These sort of simple changes will transform the TS engine. No balancer belt, lightened flywheel, lightened crank aux pulley, lightened and balanced crankshaft, the usual induction/exhaust and a remap would see you pushing 180bhp+ (and thats a conservative estimate). All for less than £1500. And the best thing is, you can do it a bit at a time, so you dont have to fork £1000's in one go.

Re: Lightened engine internals

sounds great mate, what engine do you have? i have the 2.0 and i have the same idea as you, being that i would love to lighten and tune the parts more as opposed to just adding things on to increase hp. what is the purpose of the balancer belt and why would its removal improve perfomance, why is it there in the first place then??

Same engine as you mate.

As for the balancer belt, my understanding is its there to balance the engine, giving a smoother drive (especially when in the upper rev range). Removing it may increase vibration above 4-4.5k revs. But, Im removing mine based on my experience from driving another 2.0TS which had it removed - it was noticeably freer revving and more responsive. The rest of the car was standard. Ultimately, it gives a more responsive drive and adds a handful of extra horses too. And its free to do!

Someone more knowledgeable than myself (not difficult), please feel free to give a better explanation of the function of the balancer belt!

Re: Lightened engine internals

I noticed a healthy gain when I took the balancer belt off and the car didnt loose any reliability either

Re: Lightened engine internals

about 10lb less mass to spin around... should be quite an improvement.

Whether it's a good idea to do it or not, I'm not so sure.
