Yeah, it's unfortunate the realization. I've got an 09 V with a cold air intake and took the muffler off. You should have the car up in the air and look at the pipe. It's literally a straight pipe. Two resonators. But sounds like a truck. Frees up the exhaust gas, and with my driving, close to 20k like this, it gets better gas mileage if I try and it still passes other cars eco driving. You might try better spark plugs. The 2ar (2.4l) can take our 1ar crank and rods for power and a reflash. Frankstein Motorsports on YT does this for his MR2. He eventually puts in the v6 2gr. So yeah, swap that muv. I'd say keep the V and modify it. Its not worth shit these days. And with Yota making a new Venza, good luck. I'm going the long road and at 128k. Last 35k I owned it. 19 yr, enthusiastic driver. Still solid, still pulls. I'll poke fun at bigger engine cars and I keep up. I pulled on a v6 mustang the other day. Idk what was up. Still did it though. Won't take over too well on the highway but she's much freer there too. Its a significant change. Did a 450 mile trip on 1 fill up going through Oklahoma taking advantage of their Toll roads. 80, I do a good 5-10 over no problem. Kinda scary because it's an easy but unfortunate ticket. Anyway, I'll be keeping it. I had it appraised before I touched it, at about 105k and Toyota said 6.5...nope!! I'm just going to rebuild and clean at 150k. I'm a aspiring wrench monkey so it's a must for me. For me right now, it's the only dd I have, again I'm 19. So no swaps. I'm broke. I'll save up and get something that makes more sense. Come back to the V if I have means and money. I'd love to turbo it. 2.7l turbo. I'm sure that would make a good bit of power. Don't forget Drifter, Popadakis, Ik I butchered that. Uses the 2.4-2.7 with big single turbo and nos. A few parts in house but most of the stock engine till 7-800 needed help. He said head gaskets and valves. They don't move fast enough for them. If you have money to throw, you can do just about anything to anything. You don't build power, you build to handle power. Toyota did the last half. So don't fret to hard about it blowing, you'll need to do a lot. If she dies though, she dies, just swap it then lol. I'd go all out then. LS-awd. Imagine.... Its almost hard. But if you have the fwd, they already made the channel for awd. That's why the exhaust is basically a straight pipe. Good luck. We will need it.
