Here is an Idea though, what about a complete Tubed front end, meaning Forward of the Firewall to tip... That would be the Shit!!! Would leave so much open for all kinds of options (motor swaps, Coil over crossovers use, so so so much more) plus it will give some greatly need open air/room... Should not be any harder, just a little more material... That would be the BEST way to go!!! IMHO of course, but we all know that matters the MOST on here

A complete tubed front end would be a SHITLOAD more work and design involved, I would have to redesign EVERYTHING, which involves all of the suspension geometry, way more mounting points for stuf like body panels and the other engine mounts, crash safety design, etc. All this design is WAY more complicated then it may seem and would take much longer to do than I want to spend.
If I was making a purpose built track car I'd consider it, but my car is being built for the street, and I do want to get it running sometime this century

As I said with DM's post, I'm not looking to redesign the whole front end, its fine how it is. I DEFINITELY am not out to do any radical design changes like rotate the engine layout and have to find a different drivetrain to go with it. This is just for a simple redesign of a bolt-in part.

Would this include the straps? If this could include mounting provisions for aftermarket steering racks that would be prime.
Why no cromemoly?
How much??

I'm talking about building the 2 longitudinal straps and the 2 transverse ones - the front support that has the front motor mount and runs parallel to the radiator, and the rear "dinosaur bone" as my buddy calls it, that has the steering rack running through it.
Using an aftermarket steering rack, now thats a great idea that had not occured to me, thanks for that idea! I am deleting my all wheel steering so the rack will be more comparable to most other cars out there.
I will look into a few different options here:
1)I will look into some inexpensive racks out there, like some ford or chevy racks, I'm sure they cost loads less then even our reman'd racks do. Cheap is good!
2)I'd like to consider a rack that has has a much better ratio (I think thats the correct term). In other words, a rack that requires fewer rotations of the steering wheel to get from lock to lock.
3)This probably is the least practical option for me since its really straying away from the original design of the car, but I'll at least look into it, it might be more do-able than I think: Adapting an electric rack or a hydraulic/electric rack from an MR2/S2000, etc. It would be nice to delete the power steering pump and beltline altogether, but I dont know if the electric rack is up to the task of the extra weight and wider tires, or it might require some extra sensors in the steering wheel or input from the ecu, or is might just be simply crazy expensive.
4)Are there any aftermarket steering racks out there that would be suitable? I've never looked into this subject really.
Chances are (I'm just being realistic and trying to stick to my goals) a different steering rack is not going to be incorporated into the design, but I'm NOT ruling it out - its worth looking into.
Oh, and chromemoly is not an option for us at the moment because none of us have any experience with it, and they are not ready to begin using it yet.

Saved about 15lbs, we can even sell them with a chromemoly front motor mount.
Wasn't that expensive, but no-one was interested at the time.
Some pictures can be seen here from last season when I still had the twin setup:

I assume subframe isnt the best term for what I am describing? I never did like suspension and chassis terminology, hehe. What is it called then?
Thanks for the pics! Out of curiosity, what was the price on that? If the price is right, I may just end up buying one from you instead of going through the hassle of building it
