I emailed Crower Camshaft and asked them regarding Camshaft for the 3SFE engine WITH Turbo. Here is their answer
Regrinds on your stock cams are available. Specs are typically 10-15 degrees
more duration and .010"-.015" more lift. HP gains are in the 5-15 range
depending on tuning. Rough idle is common if we exceed the above figures.
Cost is $100 per cam. Allow 1 week shop time + shipping. Send cores along
with detailed note stating engine model, intended application, power adders
(turbo, NOS, etc), rpm range to address below.
Thanks for your interest in Crower,

> I have a Toyota 3SFE engine. I'm planning on turbo charging it. Do you have a cam for it?
