would i be able to install a newer series II into my 94 SSEi without too many problems??
also would i be able to use my existing SC or would is there a difference in series I and II in the SC'*.
thanks

Definately just get the overall package of the series 2!

To use an M62 (series I SC) you'd need the lower intake, which has holes for injectors. Series II heads also have holes (correct?). So you'd have two sets of injector holes. What would you do with those? Nitrous nozzles?

hmmm, I may have just stumbled onto something here...

Sorry John, the heads have a totally different valve sequence between S1 and S2.

You need the WHOLE ball of wax to do this. Engine, trans, wiring harness, and PCM to do the swap. And for minimal gain? At higher rpm'*?

From 225hp to 240hp. You can make up the difference with a pulley.

And you could sell your 94 SSEi and buy a 96 SSEi for cheaper than a full swap.

yeah i prolably could except i just bought the 94 and really like it all except for the 174000 miles.
if i wanted to replace the engine i would have to find another bonnie SSEi in the salvage yard is basically what you guys are telling me??

The entire drivetrain, including trans, and the PCM and entire engine/trans wiring harness. Be prepared to rip the entire dash apart, run into some complex problems, and even custom fit some mounts that may be different.
