L16 turboed??

[Driftease]

I almost fell out of my chair lolololol

[Driftease]

Do turbos make the floorpans come out too cause mine are gone but i never use nos?

[smoke]

Only if you have a purple glowing light around the inlet.

[Driftease]

mine was orange

[smoke]

Only effect orange has is having to downshift and upshift 22 times during a drag race. A bit like rowing really.

[Driftease]

I have a 5 speed feeding a 4 speed so I can only upshift 19 times in a normal drag race but that car has about 1.15% more awesome than mine

[smoke]

All the real hot shit these days have two five speeds, 205 and 203 transfer cases back to back and a two speed rear. That's when the awesome really starts to happen.

[Driftease]

Nothing says launch like an availible 10,000 ft lb of torque @2 RPM and 1,000 lb of grip

[smoke]

For the first 1.3 inches, it's a neck snapper.

Dont forget you need mushroom moto zx tires.....

Icehouse had a L16 turbocharged at Canby one year. How long did that one hold together? One way to drop the compression on your L16 is to put on a U67 head.

I say go for it. With Smokes help tuning, you should be good to go.

[jimmy billy]

U67 head..ill have to look that one up. Im deffently likin the sounds of it and all i have to do is get my parts together. And dont forget learn a shit load. Just wish it wasnt so hard to find these motors.

[Kirden]

It's not... In Washington :P

 

The U67 came off of the L20B. You can actually get OEM remanufactured ones from datsunpartsllc.com, but they are $500. Sometimes people on ratsun sell them for 100-200 depending on condition. Sometimes more or less.

 

Look in the engine section for the Jason Grey sticky thread. He talks about the turbo L16 about half way through the second post for a brief moment. That will also give you some additional engine info for these old datsuns :)

Do the R1 Carbs allow turbo hats?

[smoke]

Yes, and I'm pretty sure you would not even have to fab something, I have seen hats on them that I am sure were bought.

[datzenmike]

Velocity stacks????

[smoke]

No, I think he meant an turbo hat to force boost in them.

[spudly13]

Normal intercooler pipe couplers will fit right over the r1 carbs, i cut them in half, and then actually used intercooler pipe off each carb to the plenum when i did it.

I never understood the point of turboing a carbed car. I can understand supercharging as it is a more mechanical process. But for the money does it really provide more power than a properly built LZ motor?

Guess im a dumbass...

[MicroMachinery]

Any time you're dealing with forced induction of any kind(supercharging or turbocharging), you're increasing the potential for power output beyond what a naturally aspirated engine of the same displacement is capable of on it's own.

 

And just so you know, turbocharging is actually even more efficient than supercharging. Superchargers put drag on the engine, while turbochargers are driven off the exhaust(which is otherwise wasted energy).

[RTB]

Well I understand the principle of both. But I always thought on a carbed engine it would mess with fuel delivery. You jet your carbs in accordance to your environment. Wouldn't the changing boost make the jets only efficient for a certain range then youre running lean or rich?

[MicroMachinery]

As long as your fuel pressure increases with boost(to keep the fuel bowl full), the A/F ratio should stay the same(to a point). Carburetors work on venturi, and when the air moving past moves faster(as with forced induction), the fuel likewise will enter proportionately. That part of the system works just the same way that it would with a supercharger.

 

Some things do need to be tweaked, of course, but it's totally doable. People have been doing it for longer than you or I have been alive. Do a little research if you're really that interested.

[RTB]

Thats true. Also, couldn't you only run a single carb? I cant imagine there being enough room in a 510 for a turbo set up with dual side drafts. I guess its just 2 very different approaches to performance. One is optimizing every part of the NA engine to squeeze every bit of power out of it and the other is forced induction with a lot of customization. I imagine that it would have to be a relatively low CR motor with a custom grind cam?
