Hi Rahl,

That black IC is a proper 3.0L version, and any halfway decent PDR guy or bodyshop can pop out that dent in the inlet tract. That IC requires a 1978-89 3.3L rear wing. If you want to run the stock 3.0TC decklid, or a Ducktail, then TurboKraft offers a custom intercooler package.

Either our Garrett GT30R or K27-7200 will satisfy your goals. Everything else equal, the Garrett will be a lot more responsive, and we can also offer it with a divided (twin-scroll) turbine housing to complement those headers.
Any turbo larger doesn't make sense unless you have additional intercooling, they just have too much airflow.

Leask WUR = highly recommended. We have a few in process at the moment, should have available in the next 2 weeks. Otherwise, send yours to Leask.

Camshafts: the key to this is your low 6.5:1 compression. It just sucks. Therefore IF you do cams, you need ones that make the most of the CR to maintain as much off-boost torque as possible. That means stock camshafts, SC camshafts, or Edelweiss camshafts (of which we are the US importer/distributor). The SC cams will peak in the low/mid 5,000rpm range; the Edelweiss cams carry past 6,000rpm but overall you are limited by the design of the flat manifold so the engine is usually all done by in the low 6,000rpm range irrespective of camshaft profile, porting, or CR.

Sample TK 3.3L: ported, single plug, headers, muffler, LNIC, K27-7200, factory SC cams, just 1.05bar boost.
