Zacho,
My ******* china-bay is cracking around the outside of the T4 flange, albeit not on the inside. I'm sure it will crack around the inside if I continue to use it. I think just welding a thicker pass over the cracked weld is just delaying the inevitable... What do you think?
Seeing as how I just cut the flange off it and was going to get it welded to my rb26 that I got from you, I'm thinking of saving that money, and buying a rawbrokerage or something. But they sell for upwards of $1700!!! How much time would you say you put in? If you have 20+ hours into yours, then I guess $1700 is reasonble.Last edited by ST240; 04-06-2012, 06:29 PM.RB30DET 240sx 13.00 @ 113 junk 60' - RB25DE head, 740cc, precision 6262 .58 (majorly choked), nistune - 370 whp.

Have any pictures of what you mean Andre? I am not sure if you mean the crack is on the actual flange OR if this crack is around the weld around the base of the flange meeting the collector.
Like I have said before I am not professional at this. That said, I personally like to drill the ends of cracks in anything I can being repaired. Just taking a small drill bit and taking the time to drill the ends of the crack and then welding over it can actually be a repair to last some time. Like anything repaired though Id still look for a long term solution.
You know the one that I now know after building this is that manifold prices are generally not unreasonable. This manifold took me ~40-60 hours first time round. A lot of that time is taking very careful measurements to get zero gaps on all runner joints & cutting the 6-1 collector on the jig as best I could. After the first manifold it takes much less time since you have a jig/measurements to go off. The $13-1700 manifolds are fair in my opinion. Always thought 6boost was best value I could find.
Might as well post some pics of this manifold installed.
