Will these fit? I want to replace all my exhaust manifold bolts with studs. Those stupid manifold bolts that come with HRC kit suck. After 2 days the bottom ones were loose enough to spin with my fingers, not to mention they suck to torque. Since i have to yank the turbo off to get in there might as well reaplce them. Thanks

Yes, they fit and work well. Do a search, there are part #'s in the archives. Perhaps this needs to be in the Things we've seen before section?

Below is a direct link to the section where the 4g63 bolts are listed. They have two sizes 8mm and 10mm. The only ones that fit our 420a is the 8mm. I bought four 8mm studs, nuts, and washers to anchor the exhaust manifold to the block (these studs are the four directly behind the turbo). I believe they are all $1.00 a piece. Road Race Engineering is a great shop to deal with - never had a problem.

I only bought four to replace the Hahn Allen Key Bolts that are used directly behind the turbo. The outside holes on the exhaust manifold are bolted to the block with four of the stock bolts. I have about 1,000 miles on my kit now and they never loosened up. It is up to you if you want to purchase all 8 bolts, washers, and nuts to keep them all the same.

Hope this helps,

I went to Satan to get them... Now i remember why i hate going there. Cost me $24 for 6 studs and copper nuts.
