Looking for part advice for first turbo setup...

86 GXL

I'd like it to be streetable and reliable when finished over big HP numbers...maybe 300-350whp on a conservative tune?

I've got a 1987 turbo block with bad oil seals that I will be rebuilding. I plan on doing a large street port on it as well.

The turbo I think I've decided on is a Holset HX35 with divided exhaust housing. Not much information on this turbo, the compressor maps I have seem to be just about perfect for a 13b. I'm wondering how much boost to run as well...

Manifold is up in the air yet, I'm considering making one myself.

Wastegate--I'm thinking of using a Tial 44mm to combat boost creep from a turbo capable of nearly 4 bar...

Fuel - Walbro pump, stock fuel lines. Will I be okay running 550cc/1600cc injectors, or should I get larger primaries?

Fuel control and gauges - Megasquirt. AEM Wideband. AEM Pyrometer. AEM Boost/vacuum gauge. AEM Coolant temp gauge.
