    emission test failure

    hi guys,sorry i did'nt reply sooner.as it turns out everything with the engine is fine.the bad lambda reading is due to my exhaust being too low in back pressure to give a reading.this has been cured (for me) by some local mechanics who removed the h pipe & replaced it with a fabricated y pipe...

    power limits.......

    American Muscle Doesn't Use Any Lube!!!

    i'd fit a tyre to the odd rim and put it in the trunk as a spare.its got to look better and be safer to drive on than he pressed steel space saver mine came with,although i know thats not really the point.

    power limits.......

    i was thinking about fitting a 2 stage nos kit to my '94 auto gt.other than a lumpy cam the engine is standard.what size shot shoul i go for? also how much power will the standard 4sp o/d tranny & rear axle and their associated mounts take reliably? car has done 41.000 miles&gets an oil...

    need opinions.....

    i'd start by fitting a new set of plug leads and re-checking firing order and timing as if it has back-fired you must be getting a spark on at least one cylinder. the smoke you saw was probably exhaust gas travelling back out through the air intake

    what parts first

    thanks for the reply,the car is an auto coupe and it is my daily driver so im really not looking for huge power,in fact if you saw the state of some of the roads in england you'd probably tell me to trade in for a jeep. if over the next year or so i could hit 270 hp for $4-5000i would be...

    what parts first

    hi can anyone recommend some sensible fist mods to a '94 gt car already has a freeflow exhaust on standard headers. i was thinking of cold air induction,75mm bbk maf & 70 mm bbk t/b...... or would the money better spent elsewhere?
