There are heaps of options, heaps of big thick cores you can get for cheap, Koyo single cores on ebay can be had for just over $500 delivered, Racepace triple pass radiator for $550 or you can just buy a stock replacement..........
The fact that you hear knocking on bumps and when its unstable means your suspension is probably stuffed or something is broken.......
If your wheels are /--\ you probably have too much camber, get it to your local wheel alignment place and get them to check it, while doing that they can run an eye over the suspension and look for anything obvious...
I should be ready to bolt it back together BUT i just need a confirmed answer with that sensor, as you can see in the second pic the sensor bottoms out on the adapter and i need to know what to use to seal it etc.... As soon as i know the answer to that i can get it all back together
They look similar on the outside but this is a triple pass radiator, i found cheaper Koyo rads etc but after talking to a few people it seemed the N flo was a good design as it keeps the water in the radiator longer etc....
The whistle is awesome, its one of the reasons i havent swapped the bigger turbo onto the car as i do love it!
It probably has the big Apexi mufflers which make it quiet, which is what you want for a street car...... If you want it loud and obnoxious change the exhaust.......
Will require supporting mods and a few things to bolt it up... If you want a direct fit you need to go something like a HG or Kando kit etc.....
Also, i should clarify it is a single scroll T3 rear housing, i have had a few txts asking..... Sorry if i wasnt clear!
HG or Kando etc.... Been proven so many times on here.... Go through the RB25 thread, so many good results from so many big name tuners... The NEO is a killer engine!!'
