ls13 mounts passenger side taller?
Are you using the R33 xmember or the stock s chassis one?
That's an awesome write up. Any chance I can get a copy of that AutoCAD mock up? My e-mail is sirdoc99@yahoo.com
Thanks!

factory s-chassis crossmember. it was the cheapest thing on the market... free
pics of one of them before i drilled/tapped the bottom.

ill get pics later, but i was able to mill the flange of the passengerside gto manifold allowing it to fit between the block and the frame rail. less than 3/16" taken out to make it work.
MUCH easier than cuting the flange off and welding it back on (welding cast iron....)
example of driftfun's ls13:

I'm working on an S13 with an LS1 also JS4KIKZ. I'll be buying the motorset next month. I notched the crossmember (stock S13) this week. NismoSilvia270R and mmdb's posts have helped me out a good bit.

Thats my plan, but it seems that there's no definite answer on which way to go. (e.g. R32, R33, or stock crossmember) I keep hearing that fitment of the motor is crucial for header clearance of the steering rack and the GTO oil pan and crossmember. Notching is one of the definites in this project no matter which crossmember used. As of now, which crossmember (R32,R33, or stock) is most likely going to allow me to put the motor as far back as possible?
The crossmember isn't the (only) deciding factor on motor placement. It's the design of your mounts.
Either way you're going to have to build or modify a header solution regardless of what cross member you use.
I plan on using the stock S13 member.

update with pics!! i let this thread get away from me for a little.
anyway--
Factory gto passengerside manifold milled to fit. wouldve been $10 if i didnt know the guy.
and the heatshield mod

and the second pic shows what you are talking about.
the top of the flange is still full thickness. the bottom of the flange is about half thickness. thats your angle.
it wasnt taken off all at once. test and check got it right down to there.
it works great.
maybe ill get out of classes long enough to take pics of everything installed.
i think chin still has a swaybar for some reason but im not sure. his thread has like a zillion pics, its chin180sx i think.
i think the swaybar issue is solved by going up and back. the gto pan has a couple notches in it, on my setup its kinda high and kinda far back. i could have gone really low or really far back, so i just settled where i could get to the tranny bolts and the back of the motor somewhat, even though i've had the motor in/out 4 times since i made the mounts.
i do not recall if they are the same length, sat the motor in, made mounts, drove car.
i'm working on getting someone to make a greddy sr style oil pan for ls1 that will be shorter, deeper, and with a different pick up than the gto pan. everyone in this thread will know how the gto pan is sooooo not the right pan for this swap but there is no alternative.

If I can find a GTO header I'll give your way a shot. If you could get some pics of it installed that would be great.
I just reinstalled my notched crossmember today. I'll be picking up the motor next month.
update. back from school and finally getting something done.
turns out that the mounts shouldnt be taller on one side. after i set it all in there. the tailshaft wasnt where i wanted it to be (after installing the driveshaft), so i redid the mounts.
now, the engine is in, the driveshaft is mounted, and its almost put together. need to finish the fuel line and get exh made.
