I’ve tried searching but can’t find an answer to my dumb question so I’m ready to be fillet and barbecued.

Im having second thoughts about going with a GT2560 for my build and wondering if my kraken t25 low mount manifold will work for an EFR6758/EFR6258. The dimensions seem to be the same at least for the bolt pattern. Can someone help me confirm how dumb or reasonable this thought is? I’ve messaged Kraken but not expecting an answer for a while.

Manifold works, but the DP wont.
Pick your Kraken parts AFTER you've made the decision on your turbo. Non-built engine 2560, built engine 6258, when you're concerned about money. When money doesn't play a big role, just go EFR, BUT the 2560 is still a VERY good fit for a miata

yeah definitely will have to get a kraken dp for it but good to hear someone else say the manifold would work.

your advise is sound my friend but hindsight 20/20 for me. I planned on running the 2560 on my stock engine for a couple of year but then found bad bearings when I pulled the oil pan off to drill so the plan has possibly changed… should’ve listened to all the threads saying built it right the first time. Now I’m going to Frankenstein a forged build together. I think I’ll still go with the 2560 first but want to know if I have the option for EFR sometime down the line.

I super wish that I would have just gone with a 6258 from the start. My situation is a bit different than yours but after spending close to 4k for a kit and all the hardware to make it work just to turn around a year later and buy a Kraken kit and a BW6258 was really dumb in hindsight. Buy once cry once. The EFR will do 90% of what the 2560 will do on low boost but give you headroom, especially if you already have a built bottom end. The only difference in the EFR kit vs the 2560 kit is the downpipe and some of the fittings/hardware. You will be saving yourself time and money by just going with the EFR now.
