R32 gtst over heat

Hi all! 

Ive got a r32 gtst. I was driving on the free way and flawed it abit. My temp gauge it 'H' so I stopped. Had a look no leaks or anytbing. Cruised it home and was fine. Had a look at the oil and wasn't milky either. I've bought a radiator off a r32 gtr. Flushed it and re filled it with coolant. I let the car idle for 1 hr as I let the bubbles out. The temp didn't move  at all from cold. I then took it for a drive and it rose just sbit over 'C'. Is this normal

R_34, I have done a full service including the change of the thermostat water pump and coolant before it over heated.
The water in my old radiator was pretty brown and dirty. Could that have also been a issue?

Being an Iron block, the coolant need to be changed more regularly to avoid rust of the coolant galleries in the block.

The rust particles that get in the coolant tends to block the thermostat. Your symptoms (car not heating stationary and barely heating when driven) leads to a thermostat stuck open or partially open that allow too much coolant to be cooled in the radiator.

When the car overheated on the freeway the symptoms leads to a stuck closed or partially open thermostat allowing too little coolant going in the radiator.

And you say that you changed the thermostat before the overheating so I repeat : your thermostat doesn't seems to work correctly. Was it an oem unit ?

      Thank you, 100% the intent. New coils were due and the 17" sixers look/feel loads better than the stock wheels. The aero options are so spot on.   Thanks for the warm welcome, all!

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      98 r34 gtt Been rocking my latest setup and car running like never before. Have put a good 200 miles on it since all the latest changes and additions. everything is dialed in and have been driving it a bunch.   However, all a sudden last weekend as soon as I pushed throttle passed 4k and the engine stumbles, (slow or fast acceleration) hesitates and doesn’t go above 4100 or so, like a misfire. Everything else seems fine. I had a “good” set of coil packs that I removed from car when I first got it when I changed them over to new coils. I swapped out current ones for those, but no change. I also changed the plugs, no change. Seems to rev over 4 when out of gear with no load just fine no “misfire”, but as soon as its in gear with a load of any kind, it “misfires” as soon as rpm drop back below 4 k it runs perfectly, smooth, starts, restarts and drives fine as long as I keep it below 4 k while in gear. All readings look fine, no CEL   Any idea as to what could all a sudden cause an issue when pushing rpms passed 4 k?

      Nismo GT Pro LSD configurations

      We're arguing semantics. I am saying 45 accel and a 55 deccel ramp are "2 ways". Even a 45 degree ramp and an 89 degree ramp is "2 ways", because it is literally... two ways. The cusco 55/30 ramp is a 2 way. It's two ways. I get it though - in normal nomenclature a "2 way" would be 45/45 or 55/55 or 60/60 i.e the same locking in both directions. And something like 45/65 would be considered "1.5 way". I would then say if we're getting into the nitty gritty then every locking diff is a "2 way" diff and we should not speak in 1.5, or 2 ways but ramp angles instead. Which ofc if one of those ramp angles is 90deg, that side is not doing any locking. :p So Nismo don't obviously sell 3 things. The fact of the matter that they only sell two items really goes to show that there's a 2 way and a "1,5 way" which is really a 1 way. I believe the actual lockup for the 'adjustability' of the GT pro is really just setting preload for when the ramps actually start locking up. It's not changing how much 'wayness' there is. It is (somehow) horribly explained. People just buy whatever diff and go "locks up good bruh" and that's what ends up on socials forever.
