well the problem didnt happen again , but i really didnt go out the same time at the peak of the heat at 12-1pm since that day , but if their is a problem it should happen all the time not at a specific weather? right ? now the car is perfect , but ill also do wht everyone suggested and keep u posted soon.

regardless of all of that ,driving this car once a day and goin on wot makes u forget any issue/problem in the world , hehehehehe

you wont believe how good this kit it is , no matter how many turbo cars u have been in , this kit and the car togather makes something words cant express , but the smile on your face will express alot once u drive it , i cant wait to see your reactions after u do the installing and everything . best of luck

No lag, just BOOOOST! I'm wondering how it will feel with a 4.5l stroker kit... hmmmmm... might have to start looking for a HR3.5L block to get built.

its not only abt laag , its abt everything , power,sound,looks, everythin togather makes a specific packege that is music to your ears and makes u feel like you have been unborn

do u still have ur TT 370z ? i like wht u did with the bumper , did it really make a big difference ?

What would be considered a normal temp. range for the HR and VHR?
I know newer engines are designed to run a little hotter for emissions and efficiency reasons but how much higher are we talking?

hindi1973 · 04-22-2011, 07:09 PM

well the issue is gone , it happened once it was 3 dots above normal, and the only explaination is since the coolent system was added new with distilled water and waterwetter so it wasnt runnin properly and their was little air , i didnt bleed it or anythin just kept on driving it around the block,and today i looked and to me i think the coolent is working propely and i checked the pressure from the valve and it didnt push out any air just water , one of the guys in the forums advised me , and found it after the system worked propely the car needed half large bottle of water of disttled water to add. so problem solved . it was just a matter of time and little air in the new system ..

guys does any know who's car is this? its for export only ? and i never saw it before ,the kits looks like GTM KIT ,and it has many extras as well , its not your ordinary person, but why would a person wana export a car like this after spending so much money ! the price is on the low side as well , or in other words amazing price ! if its working properly but to me its clean as hell , look at the tread on those NT05'S YUMMMMY

well i figured to update to u like i promised i know it has been long but i didnt have time , we took the car to a mechanic and checked everything , all looks good and everything , we bleeded the cooling system and made sure their was no air , also we found out the ac pressure is low around 250 so we made it 550 exacty like the green sticker when u pop the hood , anyway i ordered an upgraded radiator , i want fans but i didnt know where to get one , and gtm site doesnt give u a price when u click on the item there , so i got a CSF radiator with shrouds for our heat which is reachin 115-120f , the only issue which is pissing me off and i have no clue why this is happening , so when i drive and their is no traffic , the ac is flowing fine and flowing cold air , as soon as i get in traffic and it heats up a bit , the ac flows HOT AIR as if i switched the ac off , i tried everything and it seems everytime it heats up it goes on limp mode and switches off the ac automaticly, and when i drive off after i sweat my as* off it gets cold again , i check the oil temp and coolent temp everything seems normal around 220 oil temp and the coolent temp is either on the half mark or one dot pass it which is fine ,

am started to get pissed off ,am tryin to convince my self that when i change the radiator and the coolent system gets better the car will not go to this limp mode , fingers crossed , all help is appreciated !

anyone ? plzzz

yes, the car shuts down the a/c if the coolant temps reaches a certain threshold , its a safety feature to try and save the engine from overheating. i would think about getting the stillen front bumper move both oil coolers to the opening on each side. Get 2 little fans mount them on the inside of the oil cooler, have them wire it up so when the cooling fan engages it will activate the fans. I dont think you need an upgraded radiator as the factory is fine. also get an oil pan spacer to allow you to hold 1 more quart of oil. finally, only run straight distilled water, as this transfers heat the most efficiently.

hindi1973 · 05-15-2011, 05:19 AM

actually the oil temps are fine so i dont think we need to upgrade anything in that range sometimes the ac shuts off and the oil temps are 210-220 which from my knowldge is normal in all 370's , so am thinking about stronger fans , but i dont know where to get them from since gtm site doesnt tell u a price or anything so u cant order it , i guess ill try to vent more air by cutting the black plastic front grill and messing around with that plus the radiator and ill keep u updated . but in any case if i wanted fans to mount on the oil coolers where can i get them from ? thanks man

p.s we will need to think in all the next upcoming builds so the issue doesnt happen again so we will take all precaustion's for this matter.

am also thinking do u think it might be the meshimoto thermostat isnt good or faulty ?

yes, i thing going back to the original t-stat is the best way to start. i have had a few car come in and overheat intermittently , the cause was t-stat.

jnaut · 05-15-2011, 12:53 PM

the factory fans are great, dont cut them or replace them. the issue is else where.

Over heating and AC issues has long story with almost all Nissan motors , specially in gulf , i think you did everything could be possible with this.
usually Nissan stock engine need air come through to perform well , imagine how it will be with boost.
My advice to you , add more cold Air ducts in hood , front bumper (if you can see under hood almost no space for the engine to breath) . Add performance thermostat . You said that 2 Oil cooler been installed in car already , where you mount them and specs plz.

Always keep distance in traffic to avoid at least the hot air from other cars and don't Push the car hard in this extremely hot weather.

Last thing try to reduce driving your car in hot climate.
