Hmm...for the full conversion.....

*/C, throttle body, lower intake, accessory drive, L67 harmonic balancer, fuel rail and injectors (cannot use L27), engine harness and computer (will need computer for boost control), and other little knick-knacks.

I saw your post in the wanted section...and as Wilwren already mentioned, you are better off looking for something already */C'd, either to drive or to scavenge. I'm doing an L27 conversion myself, but I have a leg up on everyone else in the fact that it is going INTO an ssei and I already have all the parts. But doing a conversion like you are planning, doesn't make much dollar sense.

The drive axles are also different diameters.

Heads are the same for the S1 L67 and the 92-94 L27, but he also is lacking the roller rockers that came out in 93. It would be good to get 93-94 L27 or 93-95 L67 heads.

Our injector bosses are in the LIM, not the heads.

Actually, the 92 heads are different due to the non-roller rocker pedestals, but compatible. Port spacing and bolts are in the same places.

if you search, you can find posts about my Reatta with a supercharged LN3. Most all would be the same for you L27.

But as mentioned, your transmission is the weak link. I'm just, uh, kinda forgetting about it right now. I've got about 17k miles on the setup, 170k miles total on the drivetrain, and nothing'* blown up yet. I don't have any doubts in the motor'* durability (have had the oil lab tested, nothing abnormal). Though long term, the tranny issue will come back to haunt you, but hey, what etter excuse to use to pick up a 6 speed manual?
