Ok long story short, I've replaced the 4g63t 7bolt in my car 3 times over 4 years and I've dune it cuz of crank walk, in my 95 talon tsi awd. also never had a 6bolt 4g63t walk. And I have a rare 4g64 tall deck 6 bolt and was going to build it. But it looks like a lot may need modes. I planed on using the 7 bolt head and this may be a problem cuz my old head chewed up medal so cam holds are scratched. And my 6 bolt 4g64 crank got scratched by machine chop burning micro polish. I was also going to use 1g MANLEY turbo tuff I beam rods 156mm. Pistons not shore yet MANLEY or wiseco? 2g for pin. Looking to build 1000up capable bottom end and building head later but I'm on a budget $4k-$7.5k also I'll have to replace turbo cuz old one chewed up housing and shaft play is really bad I'm in need of good info this is a daily driven auto cross car, I do not race it much but it's a daily driven race car. Looking for power and reliability. I just need parts lists and to stay in budget so if I have to I'll keep using the 4g63t. Any advice would be great thank you all.

I toy around with cars and do labor jobs. I'm not an English professor by any means. you should be lucky I know how to write my name j.k. LOL sorry my spelling and grammar isn't up to par. I do this from my phone not computer.
 
Ah, well that explains it for the most part. I'm sorry but I was about ready to bang my head on my desk trying to read your posts, but wanted to ask a question or two, trying to not be a dick. (I have to try hard these days!) :/
 
Did you ever isolate why the 7 bolts were walking? (thrust bearing failure?)
Yep, thrust bearings kept prematurely wearing. I even found a couple in my oil pan. I launch my car alot and drift on rally tracks wile burning the clutch. Add a stiff clutch like 2900+ and its a bit much.All motors walk but at some point. Most not as often as 95 7 bolts well thats been my experience anyways.
