There are no forced induction kits nor CAI for this engine that I know of.
I had a set of Downey headers, a bored TB, a NWOR exhaust, no cat, FAL black magic fan, and a K&N FIPK on my '89 3VZ-E. According to the butt dyno, my truck seemed to feel a bit quicker. Maybe I can hit 18's in my truck now.

My fuel economy did go up with the mods.
My truck is 4WD ext cab SR5 Auto and in my opinion, it was not worth the upgrading. Maybe it's because I own a SRT-4 now and with the amount of money I spent on my truck, it would've benefited more with the SRT-4. If you do decide to add on performance parts to your truck, I'd say skip the FIPK. The air from the fan hits the engine and the hot air from it heads right to the area where the FIPK is. If you put your hand by the FIPK filter, you can actually feel the heated air hitting the filter. Just get a K&N drop in instead.
