1.6L -> 1.8L turbo TUNING question!
 

I currently own a 92 na6 1.6 L Miata I recently purchased everything I need to 1.8 (97 na8) swap it and when I do this, I also plan on throwing on an FM turbo kit that I have purchased. I plan on using ms2 or ms3.

I think I have everything sorted, however I’m unsure about which base map I should run, should I run the base map for the 92 1.6L because that’s what matches the harness I’m using or do I run the base map for the 97 1.8L because that’s the motor that I’m using. I’m new to this, so any help is super appreciate

Use base map for 1.8, will still need some tuning.
Source NB throttle body, when running MS, gets rid of the extra IAC hose...

I appreciate the advice🫡 Im guessing that gives better calve cover clearnce for the tps?
Does getting an nb throttle body require the bd throttle cable/bracket too or or they the same? And is the wiring on the tps a different connector?

It gets rid of the extra plumbing and makes the cold side IC piping easier.

Stolen from carpassionchannel. Thats how I did it years ago, works great.

I built a VERY simple bracket for the throttle cable, like some 90° bend sheet metal with a few holes and some spacers to get the cable positioned right, thats it. 30min of work
