Right, we have closed off the wastegate and still got only 5psi we have put 3" exhaust all the way through, we have got 5psi before and after the intercooler, we have retarded and advanced the timing, as well as setting up different O2 values we have checked that the turbo wheels arent loose we have checked the compression on all cylinders we have checked all the injectors, put a waste spark setup on it There is a link G4 storm installed we have tried running 20psi through the link and the engine just wont do it????? we have bypassed the intercooler, going straight from turbo to manifold TCS has been disconnected (would it help taking the whole unit off the throttle body?) Cat has been removed....... all the new electics have been checked over more than 5 times..... Runs hotter than usual when its idleing Have put electric fans on @ constant 92 degrees When engine is reving up in neutral, its as though its taking off in 1st gear, Sounds like its under load and has no grunt at all when test driven???????????????? Cam Angle Sensor has been replaced Just a few more questions.... Could it be that the timing belt has slipped a tooth on one of the cams? Could the crank angle sensor be playing up? Have the knock sensors got anything to do with this problem? To me it sounds like its an internal problem? Any feedback would help greatly Cheers R34-CoNvIk

yes the cat been cut out.it sounds like it under load when you rev.the blowoff valve goes off early and it set hard its not leaking.timeing been set ova and ova diffrent tunes it must be something .f**k f**k this thing lucky its a skyline.HELP .....SOS...

3'' all the way though and still the same.tested the turbo all good the motor has only done 80.000km.HELP HELP its been in the shop 4 six months we stumped

We have a R34 GTT Mods: Link G4 Standard Turbo Waste spark set up 3" exhaust Intercooler Its in the shop, and both the mechanic and us are stumpd as... The compression in the cylinders is all good Turbo has been tested, there is no air leaks anywhere even with the turbo wastegate closed off it will still do 5psi Any clues on what is happening would be awesome Cheers R34-CoNvIk

We figured out what it was... The loom that came with the engine had TCS Which was spitting f***ed up codes from the ABS and the ECU Removed the engine harness and replaced it with the DE NEO loom ( with a few more wires off the DET loom ) And now it runs mint as Thanks for your help

Yup... We've done everything from the ecu right thru the engine. The engine came with full harnes including all the parts and ecu e.t.c. The 4WD box is still in the car but converted to RWD Do you know if the codes we have are for the right thing? Cheers

Right... All done on a ENR34 GT 4 door Manual 4WD We took out the 25 neo engine 4WD, and put in a 25det neo RWD engine but kept the 4WD box in it ( removed prop and half shafts ) The DET came out of a automatic, is there any wires we need to hook up? Well the engine startes every time, we got codes 44 and 46, something about the AAC controller and ABS #44 was rectified by putting another AAC in and ECU still faults it #46 Got no idea When the emgine is running the ABS and check engine light is on, all we have done is changed the loom from the ecu to the engine, havent touched the ABS and now after the conversion the ABS is not working. Any help would be much appreciated, Cheers
