Awesome info-thanks!Long story short we had an off in the snow at Pacific forest rally and totalled the first build, It started 21 legit stage rallys, so I can't complain. The cage is legit, fia certified and weighs 105 there is no better option in my opinion. More motor in the sense of higher compression and stage 3 vs stock compression and stage 2 cams. We will keep the first motor as a spare. The 4.75 issue has been resolved one of our local rally friends had a machine shop water jet out new washers out of hardened steel instead of the junk M factory was supplying. Car will be significantly lighter due to the chromoly cage, and lexan windows, plus fixed aluminum calipers, and few other upgrades, You can run the 4.75 with a broken and or missing washer you just cant downshift to first while moving, but if the broken bits are in the fluids its going to quickly take out the rest of the tranny.
Oh sorry to hear about your total but glad about the 21 starts-that's a lot.
Hopefully the dnf's were minimal too-but in rally,of course expected.
Thanks for the info on the cage.
I'm familiar with custom cages,but haven't been on their website for a while.
Above link shows only steel choices of CDS or T45.
But their other materials are shown here:
You mention Chromoly-did you go with the 25CrMo4?
I need to study up on the metals...
Concerning the higher compression and bigger cams-got it.
Would love to see what a full built 2.5 NA can put out.
Glad to see you have the fd washer situation handled-but it sounds like you are still sticking with a 4.06 on this build over the 4.75 anyway?
I should have picked up more of those NIB Ford racing 4.06's when I had the chance when they were like $138.00
I only bought one.
I may go 4.75 on one or both(eventually)of my duratec Foci-any chance you(or the machine shop guy) could sell me a couple of those washers?
Sure sounds like cheap insurance!
