been through this before when i done cosworth management on my xr2 but was a while ago now and cant find anything with the search function so thought id ask again,

which is the better throttle body to use? 2wd or 4wd and also which is the better TPS to use as i remember there is 2 versions of that as well,

im using a different plenum cover so no need to worry about that side of it,

thanks marc

no sure about the best throttle body but i thought they where the same.
you will have to use the correct tps for what ever ecu you are using.
l8 4wd tps
l6 2wd tps

edited the title now as i cocked that up anyway lol,

with regards to the tps to match the ecu im using it will either be T6 or F88 so that makes no difference,

The PF09 Throttle Position Sensor will provide more accurate readings through the linear sweep than a PF01.

Should be easily calibrated for use with either T6 or F88 Marc.

The throttle bodies themselves are both of the same size, the only difference I recall on them is that the 2WD idle screw is secured with a 14mm locknut which needs slackening before the idle speed can be adjusted.

The 4WD unit uses an O-ring to secure and seal the screw which is recessed into the underside of the throttle body.

For a competition car you need to weigh up the pros and cons of easy adjustment on the 4WD one against the extra security of the locknut on the 2WD one.

Hope that helps

cheers will, on my old throttle body we used an R clip and lockwire to make sure the idle screw never came out and just had the o-ring to keep it secure once adjusted,
