GT30R and watercooling??
Perhaps this was metioned before, but I need some advise on finding a good source for coolant to feed into the GT30R. Can I tap into the port where the engine temp sensor is? Or is it best to tap it from the throttle-body?

Its a state of the art Garrett GT series turbo, its got a T3 flange so its commonly used in most turbo kit applications. Dual ball bearing cartrige that dramatically improves turbo lag. I think GT30R is a little bit too small for a Maxima, but it should offer great low end and midrange punch, compared to the old school turbos I see used by 99% of the boosted Maximas here. GT3530R is a pretty good choice for power on a Maxima, its got a more efficient compressor housing, and can flow more air at less boost levels. Its not the size of the turbo that matters- its its operating efficiency- which can be read by looking at its compressor map.

No.. It's my own custom kit. My setup has been running for about 2 years. So its time to upgrade from my T3/T4 to a GT30R. I was told that these BB turbos are weak compared to the 360 journal bearing units. Not sure how true that is, but I will find out nonetheless.

What kit do you have? PFI? Custom?
Do you already have the turbo? If not, did you consider the GT3530R or straight GT35R?

Ok.. That makes sense. I will tap it from that point then back to the motor. Thanks.

I've never heard of a GT3530R. Ive seen the GT30R's, GT3040R, GT3540R and GT40's. Where do the have specs on the GT3530R? I'm guessing the compressor housing is a bit lager that the stright GT30R. Send me any info on this. Thanks.

That's complete BS...there's a reason OEMs choose BB turbos over ancient inferior journal bearing turbos.

It's commonly mislabeled, even here, but it's a GT35R compressor with a GT30R turbine and should be called a GT3530R:

I would like to hear some opinions on something. From what a few, very qualified turbo Nissan guys told me is that BB turbo's don't really spool any earlier. The difference is that they spool quicker. Is this known to be fact.
oh, and my T404e is water cooled. I can post pics of where I spliced into if you would like. It is off the heater core coolant hoses.

Last I remember APS was running a GT40/25R hybrid, which IMO is a gross mismatch of compressor and turbine wheels. The slip losses from large differences will cause lag even with super small turbine sections.
Mitsu turbos are good, but any comparable size GT dual BB turbo will be quicker to spool(400-600rpms typically), provide cooler discharge temps(not a big deal if IC), boost higher, and have a much longer service life.
Until people here start playing the turbo swap game, we won't be able to show what difference the GT BB turbos really make. However, if you read Turbo/Hi-Tech Performance mags at least, you see many many cars switching from T-series to GT-series and the benefits they reap.

Why not bypass the throttle body? The turbo should do a good enough job of heating the air to keep the throttle plates from freezing open, and that is the only purpose I can see for running coolant through the throttle body. So correct me if I'm wrong.

Yeah, if you can? Post a pic so I can see how yours was setup.
Thanks.
