      I got it back on the road yesterday. Turns out I had loose turbo center housing, and the bearings were moving in it, so it was leaking.


      I'm usually not one for fake euro plates, but this one fits my project.




      Most people say their photos "don't do the car justice" but my car looks a lot better in 2D. Cosmetics are way at the bottom of the list of things to improve.





      More videos and increased boost coming soon.

            Either my new passenger side rear wheel bearing just took a crap on me (doesn't make any noise and turns smoothly) or that's CV grease collecting in a really odd spot. I was in a hurry when I took this picture and didn't inspect the boot fully for tears. Not happy to see it, CV joint boot or wheel bearing replacement, either job is a pain in the ass.


            Driver's side wheel bearing needs replacing too.

            My car is neither pretty nor powerful. Right now I'm tuned to 9psi, with a conservative timing map. It's enough to pull on a BRZ, which you could do in a Camry

            I can't wait to get to the point where I can put my det cans on and slowly dial in more advance. I need to solve this problem and replace my left wheel bearing and diff first, then turn the boost up more (15psi) and finish the fuel map.

              I like this picture, and the turbo badge is awesome! I'm pretty sure I have that plastic piece for your bumper from a broken one I have laying around. That'll make a world of difference in my opinion.

              Please... your car looks 1000000x better than my turd. I mean at least yours is all one color and your valance isn't all messed up.



              Plus your car is actually working and making boost while I'm just sitting here in NY making brake lines for my car is the artic tundra of 0 degrees.... But seriously keep up the good work! you'll get everything sorted out soon enough.

                  Thanks. I think my little piece is laying around somewhere. I have new bumper trim strips that aren't cracked up but there's no point in installing them until I get some un-cracked bumpers. I'm still working on the megasquirt guide, I've been too busy with school, work and my car going wrong.

                  Thanks. I used the output of the Zeal daughterboard (Bottom of R19 -> Zeal -> Banded side of D8 ), it worked fine until my ICV packed up.

                    I jacked my car up and ran it with the wheels off the ground the other day and heard my driver's side wheel bearing making some noise. I already did one without the proper presses and it was kind of a pain in the ass so I had the guys at WOT-Tech in Pompano do this bearing for me. It's the first time I've ever had a shop do any work on a vehicle I own.

                    While the car was on the lift I was able to see that my subframe and trailing arm bushings are pretty bad, so next week, my spring break, I will be replacing them. I thought something didn't feel right in the rear when I drove it hard, now I know what it was.

                      Hey man, cool build! Cool to see that the fix for the turbo was easy(loose chra). I like the custom manifold too:p

                        Man I feel your pain and admire your tenacity...

                        I want to avoid all of those problems so I am having my engine fully rebuilt, no turbo. All I read on the forums is the trouble they cause!! Still, I understand their appeal.

                        Secondly, I've completely stripped my car and am rebuilding it to new. Everything.

                        It will cost around 20G but I will have a brand new 1991 318iS.

                        Cheaper than a Honda Civic.

                        About one year to go before she is done...

                            Since I found out this past Wednesday that this week is my spring break (I have been so busy I lost track of unimportant things like breaks ), I get to use it working on my suspension and drivetrain. I'm going to be using Condor Speed Shop UHMW subframe and diff bushings and RTABs. They should sharpen things up in the rear. As is, my car is really twitchy with the tail out since the subframe bushings are pretty much rotted through, and on a wet road if I get into boost the rear end breaks to the right without fail.

                            The source of my axle leak, pictured below, is an odd one, and a frustrating one. The outer CV joint retaining cap is leaking at the seam where it is crimped to the axle stub. This is a problem, because apparently it's impossible to get a boot/rebuild kit that contains this cap. Someone please correct me and provide a link if I'm wrong. Really, I'd love to be wrong in this case. I'll have to take the axle out and clean it up to see exactly what's causing this joint to leak, CV axles are never fun to mess with. I will be replacing the boots and grease, and if it doesn't look like re-crimping will fix it, cleaning up and sealing the joint with epoxy (kludge alert!). I want to buy a good, leak free used axle to have as a spare though.



                            How about a picture where nothing is wrong for once? Oh, wait, you can see the cracked bumper and trashed paint from this angle.

                            The loose cartridge housing really threw me for a loop, I've never seen it before, and the bearing bosses did not appear to have been damaged in any way, almost as if the housing was bored for oversized bearings. As for the manifold... It's a kludge, at least it makes the car sound different with the unequal length runners.

                            Nice! I would do that to my car if I could afford to. Boost it! Turbos don't cause any problems if you can afford to not take shortcuts and do everything properly. A brand new turbo, rebuilt engine and the budget to have the suspension and drivetrain completely refreshed from the start would've eliminated a lot of the problems I had. It's funny, work I'm paid to do always turns out better than my own cars because I'm not the one funding it and don't take shortcuts
