      Questions on potential new purchase

      By latino_R35 · Posted

      Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers

      Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.

      Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.
