I am seconds away from ordering this kit. This was a lot to read thru, but well worth it. I have a brand new fm2 kit minus turbo and may pull the plug, start over. Any specific suggestions as I have a fully built 95 block, big valved and cammed bp4w head skunk2 intake manifold in a 901 chasis any 93octane everywhere. running a MSPNP2 no vvt. Feel free to pm Sav as my CC is on standby. power goals are the best power curve while staying under 350whp. I am pretty sure I want 6258 not sure about waste gate and if I need to get rid of my intercooler.

I made 309hp on my 6258 at 17psi. With spool that's better than a gt2560r on FM manifold.

greg made over 400hp with a 6258 and e85 at 23psi I believe, so this turbo is plenty big for most setups. No need to go with a 6758 unless going for over 400hp.

You want the medium spring for 15-18ish psi setup.

Color me curious....while the 6258 easily achieves power goals I am curious of the power curve of the 6758. When playing with GT2860’s, GT2868’s (FP hybrids) and GT3071’s I was surprised to see less mid range “hit” and smoother power delivery of the larger turbos. The GT30’s were softer but had real legs. The 2868’s were the best overall and the 2860’ hit the hardest.

6258 for that power goal. At 400whp I shift to the 6758.

Spool difference is minimal between the two, maybe 200rpm between them at most. It's more of a feel thing. The 6258 feels totally smooth and linear, the 6758 "hits" a tiny bit harder. The 67 is still buttery smooth when compared to any GT28 Garrett, though.

Not that unusual. It takes probably 1 to 6 weeks for the foundry to cast the manifolds. Then another 1 to 4 weeks for the machine shop to do all the machine work. I am assuming that Savington is getting 15-25 at a time. More then that and it becomes really expensive to put money up front. It can also be hard to predict order rates. What might seem like a good amount may turn out to be not enough, and over ordering can be just as bad.

The downside of being a small business and catering to a niche market is that there can be a ton of things completely out of your control. Especially when it comes getting things made, quickly, and not in humongous quantities.

Yea I get it. I have managed several automotive businesses from small to large. It just sucks because this is the set up I want but time has limited me. My builder has a 2 year back log and my car is up and than my turbo set up isnt gonna work.
