MIKe30's 11:1 cammed OBD2 s52 build

[e30polak]

yowza. gonna hit your thread, see if you cleared it up yet.


Gathering the last bits yet, don't plan on starting it until it's ready to roll, so it's going to be a few more days. In the meantime, here is what showed up today :)

Your car is going to sound amazing with the euro headers and this cat-back! :pimp:

Good luck Mike, now get her done!!! :hitler:

So close to getting this started and I'm stuck on a stupid booster issue. Rented a tap/die set from autozone since my unreliable friend didn't come through with his... only to find out it's a re-thread set - to fix damaged threads only, not to cut new threads. fml.

Got her started tonight!!!! At first it didn't stay running, think it's little vacuum issue. I know a couple places that I neglected to put hose clamps on and my throttle body is missing one screw. forgot to order one when i ordered my other stuff, oops.

Started it again later and it stayed on, doesn't respond to the throttle too well though. Aside from a vacuum leak, I'm thinking I either have the wrong plug in the TPS, or I need to check my TPS values and set it right.

For some reason I feel like my tps wire was plugged in on the traction control sensor part of the tb when I received the motor, but the only other 3-prong plug I can see is the ICV one - and I'm pretty sure I have that right.


Anyway, feels good to hear it run. Have to take care of the booster tomorrow, I had a lot of troubles today with it trying to cut and re-thread it. It came out like shit and I think I'm going to try and have somebody weld it up tomorrow. Hope to God that a weld will be strong enough for the lever forces when braking. Anyone think it's a bad idea?

Can't wait for a vid of the exaust tone.

The no brake booster would cause quite the vacuum leak ;)

Glad you got it running now get it finished man!

Who said I'm making any videos?! ;)

Funny though, my dad was there when I started it. He used to have a garage with his dad back in the day so he knows his way around cars. I started it up, and he plugged the mani where the brake booster goes with his finger (I actually cut/installed a small piece of hose with the check valve attached thinking it would act like it was capped off, but guess not). After the motor shut off, he goes - hm, sounds like you have an exhaust leak!

"ya, think dad? It's open headers... haha"



later on i tried it again, but I taped off the end of the check valve with electrical tape. This time it stayed running but it still wasn't acting right with throttle and the rev's would stay high and come down super slow. We'll see how today goes..

There's very little leverage on the rod, it's mostly compression. So a GOOD weld will be fine. Make sure an experienced professional does it. It's worth whatever the cost is.

I went with the cut/rethread the shaft and drill out/rethread the clevis pin option. I ended up with a weird thread size. I had some local Mennonite guy do it, as a proper tap/die set is $$$.

Thanks for the would be assurance. Turns out the guy I went to today to do the weld (an ironworker by trade) was able to thread it the right size. He said the weld would have been the strongest point on the entire rod, but the metal surrounding the rod may have been ever so slightly compromised.

He felt much better about it being able to thread it properly. I threw him a $20 and went on my way.

Yea, my dad said good tap/die sets are middle 3-figure territory $$$


Uploading a vid now :p

Very nice! welcome to the club!

Very nice! welcome to the club!

Thanks! Have to go outside and mount the master/bleed the brakes.

I tried to find a master bench bleeder kit but couldnt find one. I'll see what I can do without one, but I don't think it's going to be pretty.

I'm thinking from the sounds of it, I can get it to where it's safely driveable, but then I'll just buy a new master and new slave for the hell of it and install them later (before I drive it on a regular basis and definately before my hpde day comes up).


Trying to take it out for a spin tonight!

I have a snap-on one and it works really well but I dont think you want to pay there price if you only use it once.

sounds awesome with open headers doesn't it?! congratulations and welcome to the club :)

[z31maniac]

Don't worry, we were able to bleed the master find on the car, with all new calipers, didn't take as much fluid as I thought it would either.

Congrats on getting it running!!

Congratz dude :D
