There's a few locals whom I wrote dyno'd chips for, probably going to use one of them for a before/after, none of which are b25's. We both know the 45mm is a tad large for a stock b25, but seeing this much power from a tired one is promising. Now that everything is working properly and I have a grasp of the Alpha-N OBD1, can't wait to put them on a larger/healthier motor. Might not even bother with putting the stock manifold/car on the dyno and wasting the time, effort and money.

177 is a fucking miracle on a bone stock B25.
a fresh M20B25 with careful attention is 150-155whp.

If it's just the ITB conversion then a before/after dyno would be extremely interesting to see! If you added headers and other crap, not so much.
The odo shows just under 201,000, and appears to have had a very hard life.

Still made 177whp lol. I searched and searched posted dynographs. Seems a cammed, healthy m50b25 is about the same as these ITB's.
