Another GTR TT Z

DOOMMONKEY777 · 07-01-2020, 12:10 PM

Noice, i was just there at RAD getting my Z tuned, what turbo setup is that? Exhaust manifold goes right in to the turbo housing, is that aftermarket or is this a vr38dett turbos? Also those numbers are kinda low, how much boost and what octane is that?

EDIT: Ok on the second glance i see that those are vr38dett turbos, still how much boost and what octane?

I do have a CSF triple pass radiator. If you get one, just expect to replace it every 2 years.

Great progress! These turbos actually spool by 2800~~ with an aggressive tune. It's amazing for autoX/track.

I regret upgrading my GTR Turbos to be capable of 800 since it's too laggy for autox now. Do you have a return system already?

Congrats on the new found power!

Yeah, pulled off a 16 GTR with about 70k or so miles if I remember right, it's their own plumbing. 12psi, 93. I ask it to be a conservative tune because I will be trashing this motor for 20-30min @5.5k-7.5k rpms if the heat lets me.

What made you go with the GTR turbo's?

OEM reliability.

OEM reliability.

CSF radiators lasts about 2 yrs avg before they start to leak. Their quality seems to went down hill some the last couple of years.

OEM reliability went out the window soon as you went boost. Don't care ever if it's GT-R turbos.

I wouldn't go that far - I haven't gotten the feeling yet that CSF is intentionally trying to defraud people.

Naah, It has worked well for me so far. No issues. The radiator is cheap when you look at the overall cost of things. I will pay it every 2 years with no issues.

I didn't go that far. Other forums have reported the same things tho.

Nice build, I can't wait to get my Z in there soon for the same build. Hopefully this month since yours is almost/already done.

How's the car feel now, power/tq? Also curious if the upgraded fuel pump still cuts at hard turns/up and downhill.

Hope you like it!

It feels great, totally different car now. Power and torque are where I wanted them to be, constant/predictable and early on, not really interested in peak power. I feel it would be difficult to manage on the track if there was a sudden power output change at 6k for example.

It's not the fuel pump that was the starvation problem, it's the tank. I have the CJM Road Race pump setup from the 2nd batch years ago and have never had a problem.

I love it! There are a list of little things that need to be done still but should be sorted in a month or so, not in a big rush yet.

One thing to note, the volume is significantly less now from the exhaust, my cut outs are pointless and I just leave them open all the time. There is minimal difference between open and closed and I can only tell when I am next to a wall.

For this winter is a custom 2.75" straight exhaust. And I thought I was done.
