Adding 50 hp is just a few lines of code.
I'm curious, are we talking 50 more to the wheels or crank? For either case what are the drawbacks?
I don't know the exact answer, but usually the pros have to out weigh the cons in order for a manufacturer to produce any product out of their comfort norm. I can chip or program my diesel truck and let it run like a raped ape, but it's not going to like it for long, something is gonna give out.
As bad as it pains me to agree with 1engineer, :jk: he is spot on with compromise. You can't do any mods without compromise, whenever you change a part to make it better, it usually makes another one weaker meaning you are always going to be chasing and replacing the weakest link.
Jetboy, IMHO, why would they change their setup? Lets look at this from their POV, we have a proven system that works, sales are good, and the general consumer is happy enough. (I prefer durability over speed) Toyota has alot to lose if the new system doesn't give the consumer more power and unyielding reliability. Imagine a world where when you hear t4r and think... they used to be good, but now they are no better than the rest.
Just sayin, i would like more power too, but I don't want to give up anything else. The toyota senior design engineer over the t4r project probably gets paid alot of $$$ and is really good at what they do.
I think Toyota will incrementally increase power to make the numbers that the marketing guys ask for. Probably about 50 more at the crank. I'm sure it's a tug of war internally between output and durability. Toyota's reputation is based on long term reliability so I suspect they won't compromise that much for a few more hp. I expect the 7GR to be around 305hp and about 280ftlbs. Its easy to gain a few high rpm hp to meet a 300hp target, and in effect just sell the same engine. It's a lot harder to add torque - or in reality lower rpm power which is what we really want.
For this reason I think the 2.0L turbo is a better engine in terms of power output than even a 300 or 325hp 7GR will be. To compare the NX200t weighs almost exactly the same as the 5th gen 4runner, and is about a full seconds faster 0-60 with less peak hp and less torque. But the hp and tq are at useable rpms.
OTOH my speculation is that the RX 350 that replaces the current one must have better performance. So the 7GR that goes into the 16 RX 350 will need to improve by a substantial amount to match the performance of the NX200t. As such I think we'll see something like 350hp 285tq in the Lexus version tuned for 91 octane and 305/280 in the taco with 87 octane.
But take it with a grain of salt. I thought for sure Toyota would build the next taco on a 150 chassis.
