Yes, J&E will make you turbo pistons. 8/1 compression w .8 bar is a good combination. If you have the stock 993 cams they are great. The plastic manifold can make up to 750 or more HP. Probably do not want to run a KKK or T3 hot housing turbo. Probably a T4 based GT35 for up to 600hp. .83 hot housing will spool up fast on an EFI turbo. Probably in the 2500rpm range on a 3.8. However, you could go bigger and badder but then you need rods...

Some of the magic is in the intercooler. Bell makes a good one.

As to exhaust, what do you really have? If something like B&B headers they are to long. You want short or short and equal headers. If you have the 993 heat exchangers the M&K Y pipe is the best shorty w heat system.

Or, check with RarlyL8/Brian about equal/equal length headers w a T4 flange. Tial makes a light weight SS hot housing GT turbo that uses a clamp to mount instead of bolts that could be cool.

If you come across a set of take off 993TT heat exchangers or headers, doing a twin turbo package is possible but the new single turbos are probably as efficient and except for the exhaust, easier to plumb.

If you have the stock 993 Motronics you might consider adapting it with a larger MAF sensor and custom chip as it would keep the knock sensing function.

That's my two cents worth.
