GT-R leak #2 fixed + re-tune


Dat familiar ISMR car park.

OK so last week there was a puddle of green coolant under the car. I couldn’t locate the exact source of the problem so I topped up with water and drove straight to Indy’s hoping it was just a split hose (fingers were crossed!). Turns out it was my N1 water pump. Strange right?! Anyways, it’s been replaced with another N1 pump and whilst the car was at IS Motor Racing I thought I’d get Indy to re-tune the car.

He’s advanced the timing a bit (I really want that mid-range power back) and whilst we’ve lost 4kw or so boost is kicking in from 3000rpm now instead of 4000. Was a bit wet out today so looking forward to some dry weather (then it’s time for new tyres as these are so so old).
