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.
