Currently I've got a standard B23F motor in my 84 242, but I read on this message board that the intake manifolds and exhaust manifolds are interchangeable for the B21, B23, and B230 motors. Going on that, I got lucky this weekend at the junkyard and bought a 740 turbo exhaust manifold and turbocharger for $100 (turbo is in bad condition, but I've got another T3 already, so it was just for the turbine and compressor housings, exhaust manifold looks to be in good condition).

Anyways, I didn't have time to get the intercooler and the oil lines off before they closed, but I plan on going back this Saturday to scavenge some more.

My questions are:
1.Are the pistons interchangeable between the B230FT and the B23F?
2.Will the B230FT oil pan fit the B23F block (so I don't have to tap the oil lines)?
3.Is the intake manifold significantly different on the B230FT (I noticed a location for where the turbo bypass valve empties back into the manifold)?
4.Are the valves swappable (I assume the turbo has sodium-filled valves)?
5.Does anyone know of a decent turbocharger rebuild shop in Southwest Virginia (there's one in Salem, they claim to be Garrett authorized, but I'd like to have options)?

Read this thread, and browse some of the related topics over at Turbobricks. Basically, you can run low boost (~5PSI) on a stock B23F - stock LH-Jet, ignition, etc...

1)Yes, B23FT pistons can be swapped into a B23F. Ask for Kenny at T-bricks.

2)The oil return line enters the block on a B23FT. The common solution is to add the fitting to the B23F oil pan (carefully - must flow freely or turbo will smoke.)

3)The intake manifolds are identical. There may be some fittings in place on one and not the other, but it is all swappable.

4)Valves can be swapped, but that is a lot of work. You might just swap an entire Turbo head. I picked one up for $30.

5) Nope, sorry.

Oh, and I had one more question: Will the valve cover off the 740 Turbo (black with white letters) swap onto my B23F engine?
