Don't want to spend more than 1200 all in on performance mods. Could kinda do a turbo build with the 780$ cx kit, tcd 179$ tune, $180 for a wideband, and blue top bigger injectors running 8 psi (ish), but not sure how I feel about that (would be on stock hg and bolts). Any input as to that?
... oh and a couple hundred to have a down pipe made
also don't know what the deal is with the fuel pressure regulator... is the stock one useable on low power levels?89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...

It is possible to get 160rwhp on a DynoJet from a fully stock M20B25 engine. Doing so requires balancing of all moving parts, swapping rods/pistons around to get the most uniform deck height, precision rebore and precise matching of piston diameters to the bores, a three angle valve grind, matching of valve springs, and a new or blueprinted cam. You also need a fresh ignition system and professionally cleaned and rebuilt injectors.
We decked the head to the max to slightly raise CR and modified the cam sprocket to bring the cam timing back into spec. A minor tweak of the CPS mount was used to slightly advance the spark timing.
That engine in my Spec E30 pulled 161rwhp on a DynoJet on a 100F day. The numbers would have been slightly higher on a cooler day.The car makes it possible, but the driver makes it happen.
