Turbo not spinning on idle??
 

Hi guys I just finsihed mounting my turbo on my car for fun on a 1.0 lol nissan and it has a t25 on it but on idle it spins like for 1 second stops and then spins (idle is about 700rpm) btu once at saya round 1000 it spins like normal and you can feel air coming from the cold side. I think its jsut that the tiny engine cant handle that turbo on such low revs to spin it what do you experts think?

lol yep in cold and rainy U.K :(. It's just my car i use to drive around on etc for long journeys so I decideds to add a little fun factor O0. I made a mistake its a 1.3.

not all turbos spin at idle. If you boost fine dont worry.

Re: Turbo not spinning on idle??
 

Mine doesn't spin at idle, but if you give it a quick rev it will start spinning and stay spinning at idle. It just needs a little push to get started. Either way it's normal for a turbo to not spin at idle.

though so but just wanted confirmation. Some people been telling me the turbo is too big for my car beacsue of this, is that true? I haven't hooked up any i.c piping to see how if its laggy or not but i know there is a good amoutn of coming from the compressor when i ope the throttle and its spinning.

nothing is too big ::)

Just get it together and see how well it boost's

A T2 is not too big lol. You can get smaller turbos, but they are really tiny. The turbine wheel is miniature on a T25 anyway and anything smaller would most likely fall on its face even on a 1.3L.

haha you guys are spot on lol, made a direct pipe to see whats going on and had low'ish psi and damn that thing spins up very fast.

Another question i have is when the i.c pipe is hooked up on idle how does the engine get air?

Through your turbo's intake :1

Once everything heats up you may notice it spinning at idle. Also if it's a new turbo it will loosen up a little after use. When I first installed mine it wouldn't spin at idle but it does now even when cold.

eventhough the blades arent spinnign, air is still going through the turbo. the blade system is not air tight. so if you idling, and the blades arent spining with all the piping hooked up, the egine is still getting pleanty of air

i test fitted mine today.. spun the first few seconds of the fire-up and at idle turned off.
