You are unlikely to find anything 'off the shelf' which meet your requirements...turbo engines deliver their power much differently to a N/A engine. It may be worthwhile speaking to Newman Cams as their RS Turbo camshafts are well thought of - which is along the lines of what you need. As far as I know they are quite customer friendly in terms of developing one offs etc

The cheaper option would be to retain the standard cam or fit a mild aftermarket profile - Kent AST1 is about the limit for a nice driveable engine lol

I'll be using a standard e16se cam

When Craig had his 8v turbo it was slower with a piper cam fitted, he pit the standard one back in iirc

You need a custom cam with more exhaust duration to get the turbo spinning faster, I looked into it, if you sweet talk kent cams they would give you advice and make you one to fit your needs.

don't turbo engines require little to no valve overlap? whereas with N/A engines, the wilder the cam is, the more overlap you get? easier to overcome when converting DOHC engines, as overlap can be removed with a vernier, whilest an 8v will need a custom canshaft.

So a standard cam will do fine,

In theory would a one off cam be worth the cost for the gain?

( bit of a silly question I know )

Standard cam will be fine, nice and smooth for power delivery and has a little more lift for better power without being to lumpy to drive!
