how many lbs of boost can a stock 5s head handle....im not worried abt. the internals just the actual head.

My take on things...

Build the following :

5sfe head + oversized valves + cleaned up combustion chamber (slightly lower compression ratio) + cleaned up head ports , especially the exhaust side) ... your uncle can probably do this easy.

98+ camry metal head gasket + new head studs (even if OEM)

Stock bottom end

2jzgte cam gear machined to fit the 5sfe camshaft end

3sgte gen 1 exhaust manifold
Upgraded T04 based CT26 or equivalent turbo
3" Downpipe to a 3" exhaust

MAP-ECU2
RX7 440cc Injectors
No need for a 2bar map since the MAP ecu has a built in map sensor...

Clutch (with 280ft-lbs holding capacity), stock flywheel is fine

3sgte oil pan or tapped 5sfe oil pan

NO MBC (just get a turbo with a wastegate set around 10-12psi)
1 step colder iridium or copper plugs

EGT gauge
Wideband O2
Boost Gauge
Oil Pressure Gauge

Colder thermostat (170*)
Intake manifold gasket...

And that's it

go price that ... probably 5000 usd ... but that's how i'd build it... should make 250 crank @ 12psi ... with the ability to tune fuel, ignition timing, and cam timing and at least 25cfm of added head flow from the oversized valves (Even if you don't do any other head work with it)...
