    But how is the smoking now? That was why you vented the drain line, right? It's a concept just like a vented drain pipe in a house I guess. I never thought of applying it to a car.

    As far as the welded diff, it's totally a personal preference thing. I got totally used to it now (doesn't mean I don't notice it, just that it doesn't bother me at all), and I've gotten to the point where I really enjoy the 100% predictability of it. My dad (who is 70) and I were goofing around with the car one day including "off roading" with it lol. After we were done he had me weld the diff in his beater truck that he drives around and gathers fire wood with, etc. He's 100% happy with it.

    So anyway, it's not for everyone, but it can be super awesome. I should disclose though that I spent years racing sprint karts, so I have a special affinity for the "no differential" life. Haha

    I can vouch for that IF you shift with boost. It turns out that the 4L30e can handle a decent amount of abuse if you don't shift in boost, and don't try to put too much torque through 3rd gear.

The slip does not say but it does give 1/8 and I am usually in the mid to high 7s at just over 100 so I figure 3.5 to 60 and another 4.0 60-100.

    Let me know what you think, I tried trimming the video to start from 0 mph but it looks like I got from 10mph to about 70. And I didn't ring 1st gear all the way either. The car is hitting 10-11 PSI due to boost creep when high the power band. Also keep in mind the car is basically gutted, no carpet, panels, light weight seats, no softop or frame, no hood, No bumper supports, no spare, etc... No Auto, its the ZF with a stage 3 clutch and chromoly flywheel. Style 32's wheels with 245 45 17's all around

    If you look at the seek bar at the bottom of the video im going 70 by the 4th second the entire video is 6 seconds long:

    If the video doesn't do justice, I know I could take this car out this evening and get it to runn 0-60 in 3.5-4 seconds with a better video. About 99% confident.

    The car really lights up in redline, I wasn't expect it all. I was thinking she was going to be wore out by 6,000. Maybe the S52 cams helped?

    I'm very curious about this. I may try it on my E36 that I am draining to the drainplug but from a top mount. Super cheap China turbo in my case that may just be shot already, but kind of doubt it, I think more likely I have issues with my drain setup. I was going to pull the pan and weld in a conventional drain setup, but I always like to try stuff if there is a reason to.

    You are timing so maybe it is that quick. I am definitely surprised you are doing that well on street tires. Based on my track times, I figured I am that quick on drag radials with 50% more rwhp.

    I agree,

    It really doesn't make much sense to me either. I knew the .58 AR would spool up quick but I really thought it'd be done at 90+ or at red line - but that's not the case.

    This is with a 2.5" down-pipe as well, not too shabby. Like I said 12+ psi is going to be pretty crazy. car starts building boost right around or a little bit before 3,000 rpms

    I think I may have to install a stiffer spring as I've tried turning it up but it doesn't increase probably due to back pressure opening the wastegate

    I think we all probably felt that way until we put a fresh 4 clutch in.

    Tapped my block for my topmount oil drain. I don't have many miles on it but it's never smoked. I also have it vented.

    I have over 200+ Miles now, no smoke what so ever.

    Car is an absolute blast. I think I may have built my (within means) dream car.

    pretty awesome

    That's fantastic!! A turbo E36 turns out to be a phenomenally fun car!

    Guys,

    I have been absolutely beating on this car and it doesn't skip a beat. Other than 245 tires rubbing no issues at all

    Pretty sure I've kept in boost for the 300 miles I've driven it.

    I'm back everyone!

    Now I have crazy wheel hop in 1st and second gear. Rear end starts bucking so I let off

    Any ideas?

    If you can "drive" the car, its not built. When I first went down this road, I wanted to build a car that would be = to or greater than a 996TT. Since I couldn't afford one of those. I wanted a bullet proof 500-550whp car that I could go out and beat the snot out of with out calling a tow truck. I didn't want a car that could only run from 60+mph.
    Yes the $3000 extra in drive line parts sucks. But, to say you have a car that can only put down 500hp from 60mph on sucks more. Adding power is easy, having it all hold up and putting it down isn't.

    Looks like Zack bumped it up around 7,200. I didnt really notice it until you said something, I thought it was at 7,000.

    For now you could just weld on a $40 Max Psi brace for the front diff bolt if that is the issue. I never broke a diff bolt. It us possible tgat just running stiffer diff bushings will do the job.

    Once you start breaking diff output stubs, you need to go to the 210 diff. Reducing axle hop and not running R compound tires should make it less likely you break a diff output stub.

    You can twist a driveshaft in 2 launching if you have traction.

    You can damage transmission internals if you have enough torque.

    More power, more mods needed to handle the power. More cost.

    Some of those mods, like a 210 diff conversion with solid front mount, and a DSS one piece drive shaft that replaces the guibo with a u joint, noticeably compromise daily driveability by adding NVH.

    I've got a 188 cover with solid aluminum bushings and the front delrin bushing drilled out to 14mm I'll sell you cheap. I'll even send you the stuff to drill out your diff and tap it to 14mm, shit I probably have a 14mm diff bolt since I went 210.

    Anyways I never bent or broke diff bolts with that setup and I could bend them on command with factory bushings. I only went to the 210 because the 188 was screaming after a few pulls.
