Right so I've changed the injectors and the miss is still there. I tried raising the fuel pressure and its still there. The plugs look ok but I cant find my feeling gauge so I'll have to check their gap in the weekend. Next option would be new plugs and try another ignitor Starting to run...

http://www.supras.co.nz/pics/plugs/ Some appear to have burnt oil on, that will be from the previous build with a broken piston. Surely if it were an electrical miss there would be black plugs and un-burnt fuel? If an injector was misfiring then there wouldn't be any excess fuel and...

Will do thanks :)

Yeah - I'll double check the plugs tomorrow along with swapping out injectors. Not sure on the brand - cheap brand - but I have changed them once already and the miss never went away. Dwell in the stinger is 2.6ms - I tried up to 3 and down to 2 but there's no difference...

I will try the other injectors tomorrow night and see how that goes

0.8mm - which is what i've been told to use with the 7M ignition system

I will take them out tonight and have another look. Last time I looked they were pretty good. Its not totally load dependant - I can cruise along at say 3,000rpm and its fine - but if I'm going up a hill at 3,000rpm so I have to press the gas a little bit more then the miss is there...

Hey all I have a 1G-GTE with a 4424 Stinger. I have put this thread in the 7M-GTE section as I am using 7M injectors, ignitor and coils. I have a "very" bad miss from 2,300rpm right up till around 5,000 rpm when full boost is reached and the miss seems to go away a little. I say a little...

Well thats the thing. Inside these things there's nothing to them. The only thing I can see that's got any wear on it is the small rubber grommet/seal that goes around the shaft, that seals the front section from the middle. I cant see how this would cause a slow reaction in the BOV's...

Well true - but my ECU will shut the engine off if the wastegate creeps to much :biglaugh:

Well I've checked it over and over and over again - and this is the thing: http://180sx.locost7.info/images/bov_internal.jpg The red diaphram hits on the vacuum source that's on the rear housing - which stops it from opening properly. I will double check it all again tho just to make sure....

It’s a stage 2 T3 with 58-59mm compressor wheel and .58A/R exhaust housing. I think it's a Turbonetics - but no-one knows for sure. I've been told by a reputable turbo shop they doubt it’s a "cheap china" knock-off or "eBay turbo". The only distinguishing features are, its water cooler, the...

Yeah I was thinking about getting a 2nd one and putting it straight after the turbo, i.e. before the intercooler. I was even thinking a Bosch one, like the upgrade for the stock 7M one.... thoughts on this?

OK I removed the insert - but the sound still remains. It's deffinatly a squeak coming from the turbo, not the BOV - must be time for a new bov - bugger....

That's a good idea. I will try that today. thanks :)

Here's a few videos. The first one you can really hear it but the 2nd I cut the video a bit too short - but I love the speedo in the 2nd one :) Oh and ignore the rev counter - its not really accurate. http://www.supras.co.nz/videos/surge1.wmv http://www.supras.co.nz/videos/surge2.wmv...

That's similar to what mine sounds like. I'll take another video today

Hehe - cheers. I had washed if but really poorly for the dyno. I really need to give it a decent polish to bring out the metallics etc

Yeah it's just like an HKS one. Internally VERY similar, to the extend I cant fault it. I've checked all the vacuum lines and tried a few different sources as well. I have no vacuum leaks. On idle the valve sometimes gets sucked open (its fine as I'm running a stand alone with map so doesnt...

Also - when free revving "hard" I can hear it through the air filter....
