Great work sounds like you picked up a good one with good history!
Reading through this and other GTR forums you get so much decent info and get to chat with knowledgeable people who've been through GTR ownership and its joys and downfalls.
I've just recently had a wheel stem snap clean off in my fingers (when taking the plastic valve cap off!) and raised it on this forum for people to look out for it, as if it'd broken off at speed it could have ended in tears...I bought some new ones including the sensors from a member on here. Something you might want to check out as they all corrode after time...
Apart from that (which can and does happen to all cars with metal wheel stems) mines been absolutely faultless.
With regards to forged engines Ive read the advice/opinions and people's experiences. From that, the general concensus seems to be if torque levels are above the 'safe zone' (approx 600-620) then you're running the risk of bent/thrown rods on standard internals. Seems that decent tuners will keep torque limited to this for that reason.
I don't track or launch and with my power levels, I'm hoping I'll be OK (as I don't have ÂŁ5k+ lying around to go forged).
But then an engine failure at more than double the price and then some due to a thrown rod would be a disaster!!!!
I really do want to keep it long term so might look into it for peace of mind. Bank loan interest rates are good at the moment!
You tempted to look into the forged option at some point?
