Turbo or charger?

[Bobitupa]

Hi recently been on utube and seen a couple of boxsters with twin turbos And superchargers was thinking of maybe doing this myself but gabby got the faintest idea about where to start or who to see to do it also would it be safe in my 98 model has anyone had it done and where and more important the cost of it all would also like to hear what kind of performance it gives too I'm in the uk cheers bob

no supercharger kits currently on the market (perhaps some used ones floating around, but ask yourself why they are not getting made anymore ...). two companies doing turbo kits - tpc racing and turbowerx. i think the tpc kit is only for the 3.2L 'S' engine. turbowerx has a 2.5L twin turbo kit, but you have to remove the rear lower suspension brace to fit the intercooler.

Thanks for that I'll check them out and removing that what affect would it have on me motor ?

your motor would be fine, your back wheels would flop around a bit.

Been on both websites and they just seem to be for the s model not 2.5 also both stateside is there anywhere in uk ?

THe supers (TPC) are not being made for a 2.5 because there are not enough 12 yr old, 2,5 Boxsters left around to make it profitible. They are apparently still made for the later boxsters and Caymans.

The turbos can probably pack some more punch because they are smaller and can be tucked away easier with larger capacity. The supercharger is larger and limited in output because it can only be so big and still fit in very limited space, and there is only one real place it can go.

I don’t know about the durability of the turbo chargers but the superchargers are quite reliable. They are the same ones used as OEM equipment in the little Mercedes “Kompressor”, some ‘80s Buicks, among others. It is made by the most established supercharger company around (forget who) and is good for about 100K before it needs a $35 rebuild kit installed. Turbos, probably less life and more expensive to repair.

The downside to the super is it is a royal bit_h they are to install in the box. The turbo may be easier. Neither will pass any stringent smog inspection that I know of without some payola.

Considering how many of these things blow up just fine by themselves, I would strongly disagree with the statement that adding forced induction will be "fine."

I wouldn't remotely consider adding boost to one of these things unless the motor had been built for it. I briefly considered building my 3.8 with low compression pistons and turbocharging it, but when the thing makes 400HP normally aspirated, who needs any more than that in a 3000lb car on the street?

if you read the post in context, the statement "your motor would be fine" was a reference to removing the brace. i was just trying to respond to the Op and keep opinion on FI vs the M96 out of the dialogue.
