Hay guys, dam this hot weather, So dam hot it's not funny.

Anyway i have not been able to get higher then 12 psi on my stock turbo. Is this a heat issue? I have a FMIC, but 35 deg plus is ttoooo hot.

I readjusted the boost controller, but no good, can't get higher.

Is this a common problem. I have had no issues when cold, but today is the first hot day and hence my question.

hey mate ive noticed in hot weather my car's turbo doesnt as well, but i think its because my pod filter is closed up, so i think the added heat makes it a problem, if u hav a pod try n get a heat shield that should fix the problem

Hey

I'm sure that you know that the car won't run very well in the heat (you do live in the heat after all, lol). Mine runs liek crap.

But in answer to your question, nah, the heat won't stop you running high boost.

It's most likely the boost controller you're using.

Just to give you an example. If you disconnected the vacuum line from the waste gate actuator - so just leave it out in the air, and floored it, it'd probably hit 50 psi or something (don't try it or you'll blow the turbo and maybe your engine.

the stock turbo runs outta puff after 12psi anyways, i dont know why you'd wanna try put it up boost on a bloody hot day aswell...i can see alot of people shaking their heads right about now. you said your well aware of pinging etc and you say its fine, but most of the time you cant hear it pinging.

she wasn't pining, well not till this morning, i added soem timming. Backed off REAL Quick.

This morning much cooler temps, but turbo still seams funny. I checked it and there is no shaft play, well no more then the specs say, all good there.

Going to check engine compresion to make sure.

I am using a gozzmo IBC. I am also going to put my 10 psi actuator back in, that seamed to work better.

I tell you what, these turbo cars make me VERY paranoid. Knock, ping, bang and so forht.

hence why you leave things on the safe side especially in summer. Lowers the chances of it going Knock, ping, bang and so forth.

If you wanna go nuts with boost and timing in summer chuck a water/meth injection kit on it.

Thanks mate, i am in the process of making up some FMIC cooler water kits, and possibly injection kits aswell. For now i just need to back of a bit. LOL

Also, how much differance does a heatrange change in a sparkplug make. I have BKR6EYA, but thinking of swapping to BKR7EYA.

The reason i want to do this, is that i have a Central 20 ecu, and has been tuned with safc to get correct air fuel ration and some timming knocked out, but i still get some ping, well i think anyway. So possibly going to a 7 hetrange plug could help a bit?

Nothign wrong with it, simply put the stock one back in to get the EBC tuned to that, problem is that my wastgate still is stock and couses creep. The 10 psi gate is much better, so i will be switching to it.

It works much better with the 10 psi gate, it is just for tunning purpouses for the EBC.

Main problem since the weeknd, lack of boost over 10-12 psi, well not lack of but harder to get to that level of boost.

So i'm gona do some more research

yeh a colder range plug will drop knock a little bit...but not alot. From memory from what cubes informed me ages ago it was equivalent to 1 degree of timing pulled out i think or something along those lines.

tune your ebc for cold AND hot. Does it have two settings? If so retune for both weather conditions as stuff like gain etc etc will be different for different temps

    • So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.
    • Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
    • your right the maps for Australia came out in 2017 but are 2010 maps. i got the updated maps SD card put it in and it was the same. Same maps in my Brothers Nissan Patrol. 2020 i think his car is
    • Yeahhhh, the costs have killed me. Spent more than the cost of an engine rebuild and it most mostly servicing and a tune lol.
