I am concerned a bit about losing some bottom end power. I have founds some limitations on the JWT map, and there is a flat spot right at 3k rpm that was never there with the smaller turbo. Hell, t...

I would love to try the N1, or even to give the SR16 cams another shot. The SR16 hit a lot harder, but the 20V improved idle and the top end screams.

I would like to see how they compare on the dy...

Update on VE cams?

I was boosting hard in 3rd gear doing over 80mph, and locked the motor up. This was many years ago when the engine lost all oil from a massive oil leak. I was playing around with one of my buddies,...

Yes, hence why I managed to break 3rd gear on a P11 stack on only 10psi boost.... days after doing 3rd gear rolling burnouts. :cool:

But when I broke 4th, it was the first pull on high boost. Th...

I went through 3 gearboxes, that's when I figured out the QG stacks were the same. So I rebuilt a couple boxes and sold some. I only broke 2 QG stacks. So total I'm talkin like 8 gearstacks across ...

Element Racing used one on their G20. Worked well for them. But they never pushed more than 16psi.

Let's be real here. Even at 12,000 rpm you would need 437tq. A B13 transmission wouldn't last one pull. They just can't take that much twist.

Unsprung clutches have more harsh engagement characteristics. But sprung hubs lose springs. Pick your poison.

I broke 2nd, 3rd, 4th, and an input shaft of a P11 70V transmission. I was making we...

I would say p10/b13/b14 good to about 300 depending on use, abuse, fluid, clutch etc.
The B15 and P11 70v boxes are good to over 400whp, after that you will probably break them. I broke many.

The ...

The 50 series is still not as strong. They used these in the maxima and anyone boosted still blew them up, but they make billet gears for them now. PAR?

I am sure it will do well though, it is sui...

Did you find the pin in the oil pan?

You break an input shaft?

Oh, ok weak version then.

While on the subject of exhaust, I want a quieter muffler as well. I am using the Magnaflow straight through 3" muffler with resonator on my VRS exhaust.

I have open wastegate, and the car sound...

Oh another P11 bites the dust. This was the Rs5f70v?

I'm crossing my fingers. The 6 speed swap came with recommendations from Greg V, so I got this Spec unit from him for a 240sx. I had to buy a spec V tob. I got a 6-puck with superclamp option on th...

Try switching exhaust on SR16 cams early and you will notice a quicker buildup of boost, but on any of the 2.0 cams I have tried it loses a lot of power. I guess the cam timing of the 1.6 cams just...

I'd say, from my experiences, anywhere from 4800-5500 tends to be a smooth point. The SR16 cams will switch earlier, like 4000-4500 or so, without dipping in power delivery.

It won't affect your tune, but you will be able to load the cells you won't see while in 3rd. Like I said, peak numbers may be just slightly lower, but you will see the graph shift left a bit.

Wha...

Peak power is generally lower in 4th gear, but the turbo will boost quicker. That's my experience with over 100 dyno pulls on my car and tons more on several different vehicles.

Which dynojet is...

I suppose it could be a bad connection or wire, but it is really rare for these issues to manifest without some sort of previous trama. Accident, or replacing the headlamp.

It sounds a little craz...

Did you replace the bulb?

You happen to know what dyno this is being performed on? It's a dynojet, that's obvious. But the new 224 and 424 models readout a lot differently than the old 248c I'm using for testing.

The 248c ...
