rb20 revving issues

[cashed240]

ok here goes. . i have a 90 coupe w an rb20 that i just installed, thanks to this site and others i wired it and it starts. . . and runs, but it idles a little rough and the exhaust smells like raw fuel. i put new ngk plugs in. i am using the z32 maf because wonderful OSAKA didnt send me one with the swap, anyway it wont rev past 2500 and is slow getting there. while it was running i unplugged the maf and it had no change. . . i tried the ka maf (rerwired accordingly) and still no change, idles fine, smells rich and still revs sloooooow to 2500. i HAVE searched and still cant find an answer. please gimme some direction to look and what to ck and how.
