Alright guys... Tell me a story. I rebuilt my 3vze and hooked it up. Runs good but the junky 4runner I bought to run around with while I was doing the swap still kicks my pickup around when it comes to power. I noticed when I bought it that it was a lot more powerful than the other 3vzes I have had but I had hopes that it was just old engines in my other rigs. Anyway, I pulled the tranny in the 4runner to do some work there and low and behold, I find it has the crossover pipe rerouted somewhat. This truck is nothing special as far as I can see. Decent muffler and no cat. 4-hole injectors and a garbagy intake setup. It is nasty fast though compared to the other three I have driven. Like... I don't know... There is nothing slow about it. Is this crossover deal the reason why?

 

So can you post a pic of the details on pass side of the one with the crossover deleted? And you said it's a 3'slow' as well? Manual tranny too?

 

Sorry, I guess maybe I should rephrase. The photos are of the rig that I am calling crossover deleted. 3.0 for sure. In a 3.0 the passenger side exhaust manifold empties into the driver's side manifold where it is then emptied into the exhaust pipe. As we know this creates a confusing exhaust exit plan as the three cylinders in the passenger side get to argue with the driver's side cylinders over who gets out first. This truck has eliminated that problem by routing the crossover straight into the pipe and plugging off the usual entry into the driver's side manifold

 

The passenger side is exactly the same as stock. The original crossover is still there. Just modified slightly on the driver's side.

 

Gears and tire sizes same in all the vehicles ??

 

Indeed. Both sitting on 31s and 4.56 gear ratios.

89 ext cab: 95 3vze with 180,000 miles, Toyota intake. Denzo single injectors, 2.25 exhaust. A cat and a glass pack muffler. Manual transmission.

90 4runner: 90 3vze with 180,000 miles, aftermarket intake (not sure the brand but it looks kinda badly installed. Just bounces around in there. Cone shaped filter and a straight pipe back to the throttle body) bright yellow injectors. I haven't pulled it apart yet but I assume 4-hole. 2" exhaust, no cat, magnaflow (not flow-through) muffler. Manual tranny
