On the e28 what did you do about the steering/exhaust?
Not that there is really anything wrong with the drivers side going forward and around the other side, I just can't deal with not having proper headers on this car.
Have you seen any builds with headers? I can't find anything.

nice work Man!
Re: My ongoing e12 build (LS1/t56 coming soon)
Thanks, hopefully they work alright.
Re: My ongoing e12 build (LS1/t56 coming soon)
I have been making baby steps of progress with this heap, I'm working on a design for custom steering arms for the rack setup to be cnc machined. Figuring out the geometry is tricky though.
Re: My ongoing e12 build (LS1/t56 coming soon)
After seeing just how high the input on the steering box is, it definitely would be tricky.
Re: My ongoing e12 build (LS1/t56 coming soon)
I have come up with a design for a two function in one part... The idea is to make a bump steer spacer/steering arm out of high strength chromoly steel. It makes the most sense to me for correcting the steering geometry issues that a rack conversion causes. One cool side note is the fact that I could have a few different steering arm sets for different driving applications like autox, track or street. The design is still in its infancy but I feel it has a lot of potential.wkohler wrote:After seeing just how high the input on the steering box is, it definitely would be tricky.
This is why I love doing custom work so much, I like coming up with simple solutions to problems I create for myself.
Re: My ongoing e12 build (LS1/t56 coming soon)
For the first time in about three years the car is a roller again, kinda weird to see it looking somewhat like a car again. Today I welded and assembled the coilovers and brakes... One step closer to setting the engine/trans in place.

This looks promising. Along for the ride...
Re: My ongoing e12 build (LS1/t56 coming soon)
No promises, this is the first time in a long time I have been excited about a project... I'm not really sure why I like this car so much but it gets under my skin and somehow in a weird way I feel very connected to the thing...KrautnotRice wrote:This looks promising. Along for the ride...
Man, I think I need to get out more!
Therapy would be cheaper but not as much fun!

It's because E12s are special, no doubt.

Re: My ongoing E12 build (LS1/t56 coming soon)
The new gto oil pan kit came in the mail today, I will start tinkering with this car again soon. I might be selling my euro e24 resto project, if that happens it will make working on this car a much more focused experience.

Keep the updates coming! Really like your steering setup.
Re: My ongoing E12 build (LS1/t56 coming soon)
I'm pretty much in the parts gathering stage, to be honest I have been thinking strongly about giving up on this project... I'm less interested in this stuff each day. Very burnt out.Jelmer538i wrote:Keep the updates coming! Really like your steering setup.

Than you should quit....
Re: My ongoing E12 build (LS1/t56 coming soon)
New factory gto ls1 oil pan kit.
Now when I have time I can mock it up in the car and build mounts.

Re: My ongoing E12 build (LS1/t56 new gto oil pan installed)
I always enjoy your builds Brent! Can't wait to see how this steering rack turns out. Am I wrong to assume that if you figure this out, it might somehow fit into an e28 someday being that the e12 and e28 share some similarities??

Re: My ongoing E12 build (LS1/t56 new gto oil pan installed)
I have not compared them close enough to say, I don't know if this is going to work properly yet anyway. This might as well be rocket surgery as I am but a dust jockey.unt0uchable wrote:I always enjoy your builds Brent! Can't wait to see how this steering rack turns out.

Ls1 swap plans have been scrapped, going back to a BMW motor... This probably won't be very conventional.
Re: My ongoing E12 build (LS1/t56 No longer going in) to be
V10?
Hoping, hoping, hoping...

Lsx swaps are already played out.
Re: My ongoing E12 build (LS1/t56 No longer going in) to be
So what if they are played out...
I would love to own a big HP v8 manual sedan.

It came down to what it was going to take to have proper headers on it, was a dealer breaker.
New motor is inline/supercharged, roughly 460hp at the flywheel.
It will still require some work but makes more sense to me.
Re: My ongoing E12 build (LS1/t56 No longer going in) to be
I think this swap is going to be awesome. Not a totally unconventional drivetrain but it will be great.
Re: My ongoing E12 build (LS1/t56 No longer going in) to be
supercharged? Interesting.
