I suspected that the Heads were somewhat different in FI, but putting the B230 head on the B23 should not be a problem. Integral versus remote PS resovior also shouldn't be an issue. AC might be with some pulley differences, but is that an issue? I shouldn't think one couldn't use the appropriate crank pulley on either crankshaft. We are keeping the 87 instrument cluster with electronic speedo from the differential pickup. A machine shop given the mechnical speedo drive can make a plug if the '84 trans is used (I've done this).
I don't see it as a problem to do at all. Even a cam driven distributer shouldn't be an issue, if only bashing the firewall a bit.
Personally, I'd want to hop it up a bit, doing the math & cc checking the heads to get to a 10:1 or 10:3 compression ratio. It's probably a 9.3 or 9.6 now. A touch of decking the block may be in order. Then I'd factor in the "H" or "VX3" camshaft. The turbo or ipd sport exhaust can be a later fitment.
I've pulled a few good autocrosses at Club events, sometimes beating 240 Turbo times. This is using my '79 245 which has a B21F overbored to B23 specs with the B21F head carriying the "H" cam. I figure I'm about at the B23E specs or 140 hp and 140 ft-lb. I've low end torque *OVER* most Volvo Turbos, but naturally lose in HP if a good Turbo driver can keep it on boost.
I've also sucessfully autocrossed the spouse's '88 740 Turbo mit M-46.
I'm really quite happy with the '79 with above power mods, preferring it over the 740T. THe sport exhaust is a tad louder though, which leads to 740 use for longer trips.
