id be interested in some too if you still make them. I really need a new motor also!

Just wanted to give my 2 cents worth here. First of all you can have your stock 12a "honed out" like I did, buy a boost controller, upper hard- pipe kit,blow off vave, and 1g mas air mod and that will all get you EFFECTIVELY into low 13's! I havent even upgraded my fuelpump or pressureregulator, or even advanced my timing. Im running (up to) 22PSI BTW.

what stae do you live in? i live in illinois

OK, Ihave done the 1g conversion a few weeks ago while i had the manifold off(warped and cracked,gee,LOL!)and the first thing i noticed was that the engine idled alot better. also, i had a weird surge at the top end around 5400 rpm, that was gone until my tps went out! Any way i installed a air fuel gauge today and it says that im running rich at idleand full boost, but under decelleration it drops off the scale! Now keep in mind im at 1.15bar,around 19-20 psi, motor and injectors still stock, 122000 miles on it!!and abot 150 miles per tank, keep in mind that this car only leaves my shop to go to the track and to go for short blasts down the road. one more thing about this conversion that no one has talked about is their spark plugs!!Im a dealer for NOLOGY wires and i can tell you that i have them and another quester has got some from me,bp89,and those worked really well with the mas,any way the thing is that no one has said one thing about SPARK PLUGS!!!Come on people,more boost/fuel need cooler plug!NOT hotteras some people think. i was running BERU silvercore plugs #S5,that is their hottest plug,B4 the mas swap. after swap i noticed quite a bit of soot(unburned fuel!)around the plugs! So now i call DENZO and tell the engineer my problem and he said he had the answer which was thier new IRIDIUM plugs that run A HELL OF ALOT COOLER!!the plugs helped out because i was gettin spark"blow out"when i tried to go past 15 psi now there is no more problems.that soot on the plugs wasnt there B4 the 1G conversion beacause of the more fuel provided!!Has anyone tried to pass any smog tests with the 1G mod yet? ;D

here is a good question, im running 19 psi, 1gmas,apex avcr, modded 12a flowing about 500-540 cfm. i hooked up a new air fuel(autometer lunar)guage and i have a new mitsu o2 sensor. its reading rich at idle and full boost. it drops off completely at deceleration. is this the way i need it to read? :-/
