TRD4Runner
Full member
Hi all,
I came across this site a few days ago, not sure how I ever missed it! Been pouring over the articles as they have been super helpful (and very consistent with my experience with tuning and engine modifications)! My ride is a 1998 Toyota 4Runner. Very capable off-road, one of the best out there but pretty incapable on-road. Actually is downright boring. So I made it fun. A stock 4Runner puts down about 147 RWHP with the 3.4L 5VZ-FE engine. Mine is sitting now at 290 RWHP with the stock engine so I've doubled the power. The main power added is a M62 Eaton TRD supercharger that I've cranked up to 10 PSI. There's a lot more to it than that but that's the gist of it. Looking to learn more and crank up the power even more (safely). Latest addition was a 2.5" exhaust that goes to a 3" cat-back exhaust. Would have done a true 3" but not allowed under California smog rules. Current project is creating a custom 3" intake but will need to figure out the MAF re-tune which I'm told is tricky. I have a piggyback ECU so can do it, just need to learn how.
