Questions on MapEcu3, Turbo'd 5VZ and the 98-99 year model ECU.

What turbine a/r would you recommend for the gt3076 with a T4

 

Depending on how much power you want .63 or .82 probably going to be your choices. 63 will get you to almost 400hp with pretty sweet spool.

 

Dang I'm not looking for that much power. Which one would be the most efficient? See I'm wondering if you chose everything right and not ran a ton of boost if you could create some power while still getting good or better fuel economy.

 

Smaller is more efficient down low and larger is more at top. You might like the .86 if you want a smooth hit. You'll probably get spool in 2k area. Feels good around 3k and fully spooled at 4k. The .63 would be pretty supercharger hit. Lots of low and mid. Either way they won't hurt mileage. Just depends on how much skinny petal. I didn't get any worse mileage on my truck. Playing around different story.

 

Due you have to run premium? Has anyone got away with running like 89 octance? And can you run e85, maybe on a different tune?

 

E85 on a diff tune. Tbh i wouldn't run below 93 octane as that is what Toyota tested the first gen taco's on...

 

Dang 93 octance is so much more expensive though. And is there an easy to to switch between two tunes? One run with e85 the other with 93.

 

Yeah if you go with a piggy back you can have the dyno place just make you two swap-able tunes using a laptop, one 93 or higher and one E85. Or you could just have them tune it on 89 whichever you prefer.

 

Ok I see. So what is your setup looking like so far? Do you have plans on what you are going to do/ go with?

 

Well yes I have everything planned out and ready to go however this build sits between what muscle cars are available around Christmas lol. So if i find a nice Nova or Chevelle this build goes out the window for awhile, but if i don't then its here to stay .

 

Can you use this to add a 7th injector and add more fuel that way without having to upgrade injectors to get close to 300 hp?

And what is the fuel rail pressure in the 5vz?

 

I just run crappy ca 91. I can't get 93 and e85 is kinda rare. I might do meth injection down the road if I get knock sensitive. You should hit 300 really easy with that turbo.

 

Here in Texas you can choose 87 89 and 93 you can also buy like 110 and 150 from some places and is you go farther out you can find E85.

 

Oh I know you guys get all the awesome fuel. You get really good at tuning if you can tune ca 91. I'm lucky vp fuel is local to me for meth and I have e85 at my local gas station, but I can't switch maps on my truck on the fly unless I have my laptop.
