Well, the old 318 was officially sent to the crusher as of last night. Lots of work and memories in that car


Anyway, new stuff... I got the ARP head studs in after much finagling. It's pretty difficult to do without removing the cams. There is very limited clearance, so you have to drop the nut down vertically onto the stud. Then, you have to drop it below the stud and work it up around while rotating it horizontal. Took a while for me to figure out that trick (not sure if that made sense).

I torqued them down in sequenced steps to 85 ft-lbs. Gotta let them sit for 24 hours and retorque.










Then I got working on the front subframe. Welded in the inner reinforcements. It was tough getting a dremel grinding tool in there, but the weld was pretty simple. Gonna do the outer reinforcements tomorrow.

If possible I would widen the hole on the outer reinforcement plates for the front subframe. I've had some issues getting a socket on the lower motor mount nut. A little bit of a clearancing may be necessary.

I wish I had a fooseball table and an engine stand in my garage.

Great work and progress! Whats the goal for it to be complete?

Ok. I'll test it out with the mount before I put it back on the car. Thanks.

The Foosball table is just there because there isn't any other room for it in the house. There's too much stuff around it so you can't actually play

I go back to school in just about 1 month exactly. I REALLY want it done by then. Otherwise I probably won't be able to work on it again until winter break. It's gonna be tough for sure though. Mostly because of the fabrication I need to do for the supercharger, tuning, etc.

Me too. Can't wait to get this thing on the road.

Was one bead away from finishing the front subframe reinforcements and I ran out of welding wire... That's usually how it goes. Off to HD.

Here's what I've got done in the past few days.

Pressed the bushings on the fleabay control arms back in. We'll see how long that lasts....



Welded in the outer front subframe reinforcements



Gave her a fresh coat



Fresh 75W-90 in the 3.38



Picked up some 245/40 V12 EVOs with 50% tread for $35. Not bad...



Got to work on the engine bay













The obnoxious early model airbag sensors were plastidipped and reloated to the bumper support tubes. Hopefully I won't crash and die





Suspension arrived

Koni Yellows with H&R sports. I think I'll be swapping the sports out pretty soon for Race springs. We'll see... The springs have this pretty cool clear coating that I haven't seen before. Seems to keep them in good shape.

How much did you pay for the suspension? I want the exact setup..

Man I'm always way late to these threads, I really gotta check outside of OT like, at least once a month.

Anyway, only get races if you're looking for an absolutely brutal, no-compromises setup. That's what I ran on my car back in the day and it was absurdly stiff. Practically no body roll, but it lacked the ability to dampen even a pebble in the road.

I have your exact setup now, with the shocks set on "normal" and it still handles very well, honestly I think having a little bit of body roll makes the car feel more predictable in a turn, and its still pretty damn stiff compared to stock.

$400 shipped from bfc. They're in good, not great condition.





Joey, we'll see about the springs. The spring rate on my coils was in between sport and race, and I thought it was perfect. I would rather go stiffer than softer.

I could actually compress these sport springs by hand. Something I wasn't able to do with my coils. It's probably due to the extra height and progressive spring rate, though.

Just keep the orientation the same as the original location and you should be OK. The airbags will get initiated just a hair sooner with the sensors mounted on the support tubes, but that likely won't affect overall function. They might go off with a bit lower impact force than the OEM location but that's just speculation on my part. If you hit a parking stop hard and they go off, that'll be proof my theory was correct .

And on bumpy race tracks, cars are considerably faster if they dial down the stiffness. Super stiff causes cars to bounce over the road surface, rather than making constant contact with it.

Anyway, Konis are teh shez. Nice buy, CJ! This project is coming along nicely.

Yep, I'm hoping that the 3.38 should do a good job of making up for lack of torque.

I guess we'll see!

Yeah, I know. But I'm not sure that h&r race are really breaking into that threshold. They aren't that stiff compared to actual e36 racecar suspensions.

cj, couldn't you just get some delrin and make your own bushing(s) for the control arm??

I suppose that's a possibility. I would need to wait until I get back to school so I could use a lathe, though.

Welding/Engineering guys... Any tips for welding this up? I'm planning on using low-temp aluminum welding rods that I got from HF with a propane torch. I bought some aluminum bar stock. I'm planning on cutting out the shape of the original mount and grinding down a "V" on each side at the joint of the weld. That way I should be able to get more filler in there. Then I plan on griding down the inside gap to spec. then I was going to weld a reinforcement across the end (since it doesn't actually need to be open).

I know it's gonna be tough, and probably won't work, but I think it's worth a shot.

Re: S52, now with more snail

Short answer: Don't. The "Alumiweld" rods and similar are not high tensile strength. It's very brittle. Pay an experienced TIG operator to weld it.

Or send it here and I'll do it for free. Just pay shipping both ways.

This is what I suspected to be the case, but since I'm not a welder, I couldn't say it with any sort of authority. Just seems like a bad idea without a proper tig.

I would take you up on that, Ken, but shipping both ways would just get me another ZF.

I'm gonna see what I can do. I've already bought the rods and stock so it can't hurt. Worst comes to worst, I'll find someone that can weld it. I sent in a picture to a local place and they had no interest in sending me a quote. I wish I knew somebody that could TIG.

Isn't the primary risk that you get it welded up, but then it lets go while under load?

Don't worry, guys. I gave up. My torch doesn't seem to put out enough heat. The transmission absorbs it all. I sat with the torch center on the seam for 2min or so, still the rod wouldn't melt. No way I would be able to get a solid weld if it's that hard to get it hot.

I'm gonna contact some more people and see what they can do.

Whenever I'm done with school I'll be looking into taking some welding classes and buying a mig and tig. I love welding.
