Another possible turbo option?

for the cage. I was thinking about this myself, nothing major, just something to properly mount 4 point harnesses for use with some Status seats

It will be cool to have more FI options with the z you cant go wrong there.

trying to bring tq up to match power is better done with gearing, rather than swapping out your kit.

All you are doing to bring them closer is moving the powerband down, based on the definition of HP/TQ. You can do (effectively) the same thing by shortening the rear gear.

If you shorten the rear gear to 4.64 (really short), you'd get effectively the same feel as if you'd kept the stock rear gear, and had 508tq. Of course, you wouldn't want to go that short, but you get the point. You've got enough in the way of CR gears that you should be able to get away with something pretty short for track use.

Trying to fix your problem with a turbo kit means you are trying to improve the piping issues, and having to run a more expensive turbo with a broader efficiency curve. While it would be nice to have those things, I can't imagine going from one single to another, especially before you identify your real issues on track.

Well said Dan,

I think what I took as increase in torque only was really to increase efficiency, which the increased torque will be a byproduct

this thread has doubled since i last looked at it..... yikes. hahaha

This is the compressor we'd be using... .

You can use whatever turbo(s) you want, but this engine will not make the torque most people are used to seeing with the VQ35de's. Not to mention that things have not been pushed hard since there are only a few people with built engines.

For a view that isn't as close up I sneaked in and took this. Might have a fitment issue but once that's resolved I think torque should increase a tad.

We'll be overhauling Tim's setup with a built motor at some point in the future but with other back to back testing that we've done with similarly spec'd turbochargers, im confident that we will see a noticeable gain in torque and a widening of the power band.

I see you snuck a camera into our shop, huh?

Aside from the bonus' of a built motor, where do you think the choke points are on the current setup? i.e. what are you looking to change and evaluate?

In the end a turbo is a turbo. Yes the new billet wheels are a bit better, and the turbine wheels are also improving, but in the end the idea is to deliver air/boost to the engine. You just can't make old school V8 torque with a modern high revving V6 which was designed to make top end HP.

Even the twin scroll (most efficient turbo configurations due to superior scavenging) reached maximum torque and simply stayed there all the way to redline, much like an N/A engine. Just my experience with these engines I guess.

All Turbos aren't equals. A turbo isn't just a turbo. No one would expect to see the same results from a 6266 or a BW S300SX compared to say a similarly sized Turbonetics or shelf Garrett unit that technically "measures out" the same. There are a lot of advancements in wheel designs, housings and more. Actually enough to an extent that people are upgrading similarly turbochargers for redesigned units.

I'm not trying to reinvent the wheel here, just make it turn faster through other options and little things I've picked up through out my time with the platform.
