  1. the turbo starts to come in at 2500 and hits 7psi at 3000 and full boost at 3500, so once in second gear there is no lag as the revs are allways at the right level to hit full boost as you change up.

    in the lower gears yes especially with a low compression engine

    the ball bearing turbo will hit boost faster about 500 rpm sooner,£1200 would be money well spent

  2. crank, conrods pistons balanced

    arp conrod and main bearing bolts

    expensive but super strong 2/3rds sronger than stock

    heavy duty oil pump

    rods shot peened to strengthen them

    ceramic coating on the piston crowns

    forged pistons if you are going forced induction

    total seal rings

    are the pistons the same size as the ones you took out?

    if so you will only get half a job done.

    the bores will be worn if the engine is the original one

    you should really as mentioned get a rebore and use 2.9 pistons, or go for 3.0 pistons,

    you will have to get the cylinder walls checked to make sure they are thick enough to take the 3.0ltr piston rebore

    have a stroked crank and go to 3.1 or 3.2 ltr

    the mods depend on how deep you pockets are

    make sure the company reboring the block have the experience in doing them and the right equipment.(the right torque plate)

    there are very few engineers that do and they will try to hone the block out,

    i found out to my horror, my local engineers said they could do it, and honed cylinder 4 out a tiny bit off center and the block lasted a few thousand miles before the cylinder went oval.

  3. hi some wiring help please (not my strongest subject)

    on the loom which supplies the lambada probe / o2 sensor

    four of the wires go to a connecter which then is plugged into the o2 sensor

    my question is what is the 5th black wire for and connected to?

    mine is cut off and icant see any where it should be connected to

    is it an earth to chassis?
