Just FYI the stock 90-97 spark plug wires will fit into the VVT VC if you trim the rubber a little bit. I used a razor blade and slowly removed rubber off the top of the boot until they fit down fine. I have had no problems with them like that.

The bracket for the 94-97 ECU grounds can be transferred over to the 01+ block. IIRC, the OEM 90-93 ECU grounds attach to the back of the intake manifold, and those can just be attached to the 99+ manifold.

Alrightly. So Oregonmon has his VVT swapped '90 with a MS3, and GreddyGalant has his MSM swapped '92 now with a MS2PNP.
They're both screaming for tachs.
I've Ctrl-f'd every post with the word "tach" in it, and all they seem to say is "wire it to the tach".
Is this at the cluster? One of the ignitor wires I capped? Please spoon feed wire color and location. Thanks.

Following the instructions in the op connects the tachometer in the cluster to the tach output wire (2I). If you've connected it that way, and you have a tach driver circuit, and it still doesn't work, you probably need a pullup resistor.

Ok someone explain this?
Is this the 1k ohm resistor between -IG and GND in the diagnostic connector?
Tried that (both ways) and it didn't work. Black/white and yellow/blue are soldered together, tacho pin is enabled in TS, and still no tach. WTF.

On every 90-93 USDM car, if you loop the wires as directed in the OP, you get a wire that is connected from 2I (black/white) to the cluster (yellow/blue) without routing a redundant wire to do the same job. Just FYI. Adding a wire to do that job is unnecessary and clutters things up.

Thanks for putting this together.
I'm in the process of selling my entire powertrain (engine, trans, MS3, etc etc) and turbo setup to someone with a NA (think its a 95).
I'm going to install a LFX.
Being that we can use all of those working bits (I'm keeping my radiator/ fans, throttle cable, steering) how much of this will be necessary to perform the swap? I imagine I will be forced to use the GM harness and ECU so I could even swap over the harness.
We are thinking we'll simply take everything out of my car and swap it over to his.
