This side shot is pretty good for showing what body parts are tacked on for camouflage.

Correction. Late 80's. 1989 was the last trubo shipped to the US. In 1989 at one point the 944 turbo was the fastest car Porsche produced that topped out @ 161 mph. This same car even outperformed the 1989 911 turbo on a track test. Today a stock 944 turbo in good eng shape will give a 986 S a run. Turbo lag is what kills it but with a chip and shimmed wastegate it will perform in the 987 S league or better. It seems Porsche intensionally put restriction on the intake plumbing of the 944 turbo. By removing the stock airbox and snorkel, stock AFM and replace with a MAF and cone filter throttle response was inproved drastically specially in the 4k rpm range. Here's a graph of someone measuring a stock airbox vs a MAF.

A turbo 4 Boxster and lighter weight will be a great combination. I can already picture Porsche intentionally restricting this car as they did the 944 turbo so it doesn't outperform the S and 911's.

I know this topic sort of died but I wanted to raise one more faq on Porsche and their other turbo 4's they made in the past. I don't think they will make the Boxster turbo this potent but look at the potential.
