after doing some mods(intercooler with piping, dump pipe, air intake, safc II, AVCR) to my car i encountered this problem.....

when the car hits approx 4500 rpms it just starts to choke, loses power...higher the boost more it chokes more power it loses....

first thoughts were that the fuel pump is not pumping enough fuel so that was changed( WALBRO 550hp )spark plugs changed as well, still problem persists........

after that coil packs were checked and tested and are all good.....

anyone experienced anything similar to this please HELP!!!!

dont know what to try next!!! :huh:

Gap your plugs to 0.65-0.7mm if you haven't already. and use BKR6E.

that was done as well, didnt help.....

spit fire coil packs..

yeah, thats what i need, spit fire coil packs....

after few hours of testing again today i think problem was identified....

faulty ignition amplifier.....when it was replaced i got much better results straight away....after that coil packs were tested again one by one...this time they didnt test as good when car was running on high rpms....2 needed to be changed, 4 not in very good condition but they will do for now.......

car is running good now but i dont know for how long so i definatelly need a new set of coil packs and i think spit fire is what i wanna go for....

does anyone know a good place in perth where i could get set of those????

cheers :)

    • Kinda glad I never got to this ..    https://www.facebook.com/groups/1483859159195077
    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
