Yea thats the way to do it, either a 2jz-gte or 1jz ignitor, I'm pretty sure there the same part. A 93 should be a 2nd gen 1jz by the way, look at the intake turbo pipes above the turbo's, if the PCV vent is on the Y-pipe its a 1st gen, if it's on the other alum pipe beside it, it's a 2nd gen. All 1jz-gte's are MAP, MAF is what's on the 7m-ge. So you lengthened the wiring harness yourself? Tedious work but it's worth it.
