More research.
I'm about 30 minutes from buying a complete volvo head for the little 4 banger. As it is w/ V8's, induction is the key to power, and right now, a Volvo B234F head is the best head out there for this stupid little engine.
Problem is,......it don't just bolt on.
I mean it will "bolt on" but it is about an inch too short in back. (So you have to have a 1x1" block of alum tigged across the back of the head to cover exposed water passages in the block.
The pressurized oil passage has to be reloc'd, the drain backs re drilled.
The head itself is actually off center bore spacing wise, but not so much as to cause interference issues, and CP makes a piston that actually takes that into consideration. (just means that the only piston I can use is one from CP)
The block dowels don't line up.
The Volvo head uses the intake cam to drive their distributor, so you gotta block it off and weld it closed.
You have to modify (read grind open the holes) in a FP wire lock or Cometic head gasket to match the head/block water passage mis match (can you even fathom grinding on a head gasket that is gonna see 25 psi of boost)?
The posted pics from the guys that did this swap are old, and look like the guys that did it are named either Frank, Enn, or Stein.
This actually doesn't look bad, but look how much stuff is going on:
And,....am I seeing things or does it look like dude might be ducting waste gate exhaust back into the exhaust at the turbo inlet?
I mean I've seen TT'd V8's w/ full serpentine accessories included that don't look like anywhere near as "busy" as these examples do,and I intend to have PS and A/C on mine.
