1990 Toyota Tacoma – Haltech PS2000

This was a little bit of a long project for the client as the client worked diligently to put in a 1997 3.4L (5VZ-FE) motor in this chassis.   After the motor was in, the Haltech PS2000  was wired by the client.  It was fitted with some  individual GM LS1 coils and a Haltech Wideband was also put into the mix to help speed the tune.

The truck was delivered to us and after many hours of trial and error in trying to get the right configurations to start the the engine and making sure the engine was in TDC and it had not jumped a tooth or something we managed to bring it to life.  Even though we managed to start the engine it still had a noise of a miss and then the (passenger side) head started to show sign that a noise was emanating from that side.

We notified the client and he came and picked up the truck so we could take it to a Toyota specialist and have the motor diagnosed.  After a few months elapsed the truck was coming back and the problem was found and rectified.

The problem ended up being the tensioner built into the exhaust cam having a bunch of slack.

Truck was brought back to now do the actual tuning on the Platinum Sport 2000, a little street tuning was done before it was loaded up on the rollers to get the final touches on the timing tables.

Tuning and test were mostly done in 3rd gear.
Best power ouput was 127whp or 142whp(dyno jet) on this set up.
Down the road a TRD Supercharger will be added to deliver more WTQ since this car is going to be living doing
much rock climbing duties.

Would like to thank Nick for trusting in our recommendations, calibration and engine management system to get his project off the ground.
