Bolt on turbo kit (28 Viewers)

If stand alone could pass an OBD2 readiness scan in emissions states, I would be ponying up the $$$ right now. Stand alone with a smaller turbo (or a larger turbo with modern efficiency features) would be freaking amazing. Anybody who doesn't live in a state where they plug into your diagnostic port to do emissions testing should seriously consider spending the extra money/time/tuning to go that route. I think the 1fz with the freedom to tune as you see fit could match any v8 swap.

Yep it really does. I have put up dyno's of my truck with a small turbo making 400awhp. When a 6.2L V8 swap only makes around 265awhp.

I think I would be happy with the kit Scottryana is putting together. Looking for more boost is a rabbit hole I don't want to go down. Once you get the computer right then there is the arp head studs mls head gasket and on and on.

Bingo.

To me, it's not even a question of how much boost, but boost being available at low rpm. Like many modern turbo cars (audi 2.0t, ecoboosts of all varieties, honda 1.5 turbo, etc), a small and clever turbo just makes it feel like a big motor. No lag, no hesitation, just power when you want it.

I feel like my 1fz has plenty of low end, it just falls on it's face in the mountains at elevation on the highway. I went down to Phoenix and had plenty power at that lower elevation. If I lived at sea level I would be ok with a stock 1fz.

It does have the power, it simply loses a lot of it in the transmission and transfer case.
Especially going from 1st to 2nd is robbing you of a lot of power.
A better transmission, more efficient one, would change the perception of many people driving 1FZ everyday.
Now, boost it a little and have a different tranny, would be a wet dream.

Would be nice if someone could figure out how to adapt one of the newer 8-10 speed AISIN automatic transmissions to a FZJ80.

That's my plan

Are you willing to do the R and D necessary to mate new 6-8 speed autos?

Didn't think so.

 

[Rwhat]

Why is that the question?? For $2k it is a piece of s*** ECU. You could go Haltech or Motec for that price.

Please explain this then. I don't doubt you.

 

[Rwhat]

I see a lot of post of your HP claims, but no good videos or actual data. What can buyers expect without some cool videos?

400 AWHP sounds pretty sick, what's the drive ability of it? Is 400 AWDHP a daily driver or a 16 second quarter mile queen?

[scottryana]

I have posted several dyno sheets and a 0-60 video run in 6.x seconds @6600lbs. But that is with my turbo setup, not what this kit will be.

10 spd sounds really nice on the paper. In reality people complain about gear hunting. And that's not aftermarket.

In the other thread we have it figured out already. At very minimum $5000, not including labor, I would say it is definitely not worth the effort of the money.
With that money you can boost your engine very nicely and get a much bigger smile on your face.

It cannot be done for less than $2000 no matter how you slice it and dice it.

 

[dogfishlake]

I know that isn't the set up you are designing @scottryana , but I just had to post that up. Your truck looks like it's going to rip the straps out of the floor!

What allows then to get power down low is not just the turbo but direct injection along with the boost.
to much cylinder pressure down low is just going to ping. with direct injection there is now fuel in there as the piston is coming up so it cant detonate until it is added later near the top

I have the 10 spd trans in our Raptor. It doesn't hunt really at all and drives very seamlessly.
In contrast the 6spd in our 16 Tacoma is all over the place, drives me crazy and I hate it.
It comes down to how its controlled. Also the Tacoma has no torque so it needs to down shift all the time

FYI the 3.5L ecoboost in the ford is direct injected with twin small hi-tech turbos and makes almost full torque down at 2600. regardless of turbo tech it couldn't do this without direct injection

 

[scottryana]

Well I am not so sure that is a benefit of GDI (Gasoline direct injection) the main benefit of GDI is increased fuel efficiency, since you are wasting very little fuel and you can also run leaner. The biggest problem with traditional fuel injection is you can really only inject fuel efficiently when the intake valves are open enough to get the fuel in the chamber. The timing of the valves and injectors are not as precise and you end up with a less than perfect atomization of fuel on the closed valve at the beginning and end of the intake cycle. With GDI you have the injector sitting in the combustion chamber and it can spray fuel at anytime including the end of the exhaust cycle.

So while you could not get the same fuel mileage out of the 3.5L Ecoboost with port injection you could make the same power at the same RPM's just at the sacrifice of MPG.

One of the downsides that many people are finding with the GDI engines is that without fuel being sprayed on the back of the intake valves they are getting terrible deposits which limit air flow and cause sealing issues. (One of the reasons you hear fuels claim they have detergents added). SO many manufactures are doing both port and GDI.

This is a picture from F150ecoboost.net what shows the Ecoboost valves.
