Hey guys so looking into buying a skyline soon and just had to get some input. I was looking at a beautiful gtt already decked out with a decently modded rb25 but then I found out about the GT4 so I looked into buying one of those. I found one for way cheaper than the gtt and now I'm interested in buying it because of the all wheel drive. Also cause its bone stock and unmolested. Now my next questions are how difficult is it to put a turbo on the rb25de sand how drop in is the rb26dett. I have seen only 1 post about the swap for a GT4 but I cannot find that post again and every time I try to look this stuff up nobody has any info on this and I was surprised even YouTube did not have anything, any ideas ?? Just want to get the details before i choose unwisely.
