Hi im having trouble with the car and its starting to do my head in, if any one can help it would be much appreciated.
Ill give a brief spec. R32 GTR (r33 engine), HKS gtrs turbos, Apexi power FC, Splitfire coils, Greddy iridium plugs, Tomei fuel pump,
Tomei pressure reg, Sard 555cc injectors, running around 500bhp at 1.3 Bar(when its running right).
The car runs ok flat out under 1 bar boost, it will give a slight pop just before the turbos come into action,
its when i turn the boost higher than a bar and the revs hit 5,000 the power just dissapears and the car starts to pop
and miss its not violent but the loss of power is very noticable. To make it strange you could push the revs on in third with
the car spluttering and as soon as fourth is engaged power returns with no miss.
I replaced the plugs 2 days ago with greddys and noticed a slight improvment(gap set at .6)
More recently with a slight load uphill the power comes and goes but with the o2 sensors
off this problem is all but gone.
If any one has any suggestions please help this is really starting to annoy me ive run out of things to check
and the moneys running as thin as my patience.
Thanks, Kieran
