Re: ready to make needed

if you don't know where you're starting from then you should really find someone who does ... rather than getting bespoke additions to the car in the hope that you'll get to your magical figure you need to take it somewhere that has experience in these matters and hand the car over (with lots of money) ...

... the obvious answer though is to buy the 3.2 version ... would probably be cheaper too

Re: ready to make needed

With an exhaust, induction and re-map you'll probably see the 165-170bhp

Re: ready to make needed

Yup I'd say new air induction and new exhaust from the cat backwards first, then remap when complete. You'll probably gain around 25-30 bhp total. But beware, the 2.0JTS are often 25-30 bhp down on quoted bench figures when actually mounted in the car

It'll still be much better to drive afterwards, just don't expect to reach the magical 200bhp figure which I would also love from my 2.2 JTS!

Apparently the induction is a shocker particularly on the 2.0 but also not good on other JTSs...

Re: ready to make needed

look here, don't know about the differences between ts and jts,

but mentioned was head work, cams, induction, properly tuned exhaust and a remap.

Don't know if part of the idea is to make it rev higher also?

Re: ready to make needed

To be honest you'd be better off with either the diesel or the V6 if you are wanting anything close to 200bhp. Extracting that from the 2.0 JTS is going to be very expensive, these cars are often 130-140bhp as standard and even with a remap, induction and full exhaust you're not going to get that much past 165bhp or so - right where you're expecting to start

By the time you add cams etc, you might get 200bhp, but it won't be the most driveable thing in the world, and emissions and fuel economy are going to nose dive. The 3.2 makes much more sense I'd say.

Re: ready to make needed

Yes, it is going to be both expensive and involve a lot of work.
I have a friend who owns an Alfa 156 JTS, after a lot of problems and a lot of money spent, he got the car pretty much as he wanted it. I will not quote any figures as they are quite hard to measure, really, but the list of modifications is :
- battery to the boot
- BMC CDA where the battery was(I do not think it matters much)
- Supersprint manifold, with heat shield(the textile sort, the name escapes me at this time)
- custom straight through center
- Ragazzon backbox
- C&B stradale medio cams
- increased CR(not by using other pistons or conrods, by working the .... lapsus due to sleep depravation, damn it)
- Dastek Unichip + remap (not the best remap, if you ask me, but ...)
The ca is very loud, at least for me, especially when cold at idle, quite some droning inside, but it's pretty fast.
Although I would have sold the car in stock form and would have bought a GTA.
