Any Turbo kits or interest for a Vantage?

I love the Vantage, but it's just too slow for me to justify the expense. I was wondering if anyone has done a turbo setup for one or if there's just not enough interest for someone to step up and do one...I love the car, just need some more power, and the WAY overpriced supercharger kits are a joke imho...

just curious, but how is a turbo kit going to be any less expensive? AM's are very low production cars. and very few buyers are looking to modify their car so extensively. for a company that makes products for these cars, they have to increase prices to recoup their costs to develop, manufacture, and sell their products.

+1 I don't see how it'll save you money either.

A sub $1000 turbo kit for a Vantage?

Yeah go right ahead and put that on your car and watch the hilarity ensue! "My engine isn't running right" "My car won't start" "My engine is sputtering at high RPMs" and so on and so on...

Somebody message the seller and ask to see a picture of one that has been installed, I'm interested in how good their photoshop skills are!!!

In all seriousness, I would be very wary of anything that seems too good to be true. I know from our experience with the AMs that the ECUs on these cars are some of the most difficult to deal with. Most other modern vehicles are on a Bosch EDC17+ or ME2.8, sometimes Siemens. Point being, the protocols for those ECUs are 10x easier to deal with than the AM.

The other thing to consider is, if you are adding forced induction to a NA vehicle, then you can't just tinker with the existing settings and make it work, you actually have to write tables from the ground up which control boost settings and either integrate them into the existing ECU or utilize a secondary unit to control the new factors etc. etc., and that's just the beginning of it. For example, assuming that you can gain control of the boost, you then have TPS and Mass Airflow sensors which are expecting to see certain airflow values at certain throttle angles. Forced induction will throw that out completely and then you'll have to recalibrate the expected values for that entire table (probably at least 200 discrete values per table, depending on the vehicle). Once that is done you'll probably find that the fuel pressure is far too low for the new airflow and you'll have remap the fuel tables to increase the fuelling rates. Most likely you'll realise that the injectors are now running far too close to capacity and that they will need to be changed to larger volume units. Remap the fuel settings again for the new injectors. Probably revisit your TPS and Mass airflow settings again to fine tune them now that you've altered the fuelling.... and that's all assuming that you can get a secondary ECU to communicate effectively with the primary ECU and take control of these functions.

And so on, and so on. So yeah, if someone can accomplish all that for $1000.00 (or $10,000 even) then I will take my hat off to them!
