alright about the spacer, thanks lucky. Vfast, where can i get some info on the professional products T/B? whats the significance of the adjustable tps? is there a website i can check out their T/B's at and get info on them?

Adjustable TPS so you can ensure you have the correct voltage being sent to the ECU if you have changed your idle speed. Normally you would have to wallow out the tps holes to modify it enough so you can get some adjustment outta it. Also, I'd go with a 70mm TB.

lucky is only partially right about the spacer plate. the EGR valve mounts to this spacer and it can run hot with the exhaust gases flowing through it so they piped engine coolant through it to keep the temperature down some to compensate for the temperature effect of adding the hot exhaust gas back into the fresh air flowing into the intake. Once I took my '88 off road, I removed the EGR valve altogether and plugged the passageway in the upper intake with a marine expoxy compound. I also plugged the air passageway in the spacer plate and removed the coolant lines from it so the intake air stays as cool as possible and it isn't being diluted with the burnt exhaust gases the EGR valve used to add to the mix. you wouldn't want to do this if you still have to pass emissions testing, but on a drag car ever little bit helps. You'd be surprised how much cooler the intake maniford is without this EGR crap running through it.
