exactly what i thought, then i noticed the gloves in the goofy face tranny picture.

nice ride, totally :)

Little update on my "Home made turbo" setup
 

I have posted my build, which is complete, before and said that "I am building a motor for more boost." So, my BMW 525 is now watching me build another engine for it! Things are coming along.

I think I am done buying parts. I went a little overboard in what I am replacing but I figured do it right the first time and not regret things later. So I am doing all of the chains, all of the chain guides, tensioner, oil press sender (yeah, i dunno why either), I sourced 30 new oil pan bolts to keep my powder coated beauty looking perfect, sourced new main bolts, valve stem seals for the non vanos head, and all oil related gaskets and seals are brand new. Its hard to find some of these parts - I used autohausaz.com for most of them but they don't have everything.

Stuff not in the picture is valve cover gaskets (all), some plastic cover caps, new caps for the valve cover, and some dowels for the flywheel/crank/etc.

ARP studs, and a 0.140" MLS are here also.

To be combined with these parts:

It should, hopefully, be one of the cleanest engine rebuilds I have seen! Just need to find a little bit more money to go to the machine shop and get the block decked and honed, the head checked, and then powder coat the block and head. I am going to probably be soda blasting my head this weekend and re-assembling it once it's checked out up at Jays shop.

Progress feels good!



UPDATE


So as everyone knows I bought a '92 E34 525i and am now getting around to building it. With much thanks to Jay (Multiplex) and his gracious use of cleaning machines and such, I am making this thing look like it never has before.

Here are some pictures of how it looked about 6 hrs ago:

Then, Jay and I tried out the soda blaster - for those not familiar (and I had never used one until today, though I researched it...) it uses essential sodium bicarbonate (baking soda), water, and air pressure. It's not an abrasive - it has more of a chemical reaction to hitting the aluminum at accelerated speed... people describe it in layman's terms as "exploding on the surface" so basically the soda breaks down as it hits, without ever affecting the finish... and so... this is what I was able to accomplish:

and most importantly... the combustion chamber! Pay special attention to the valve seats! Freaking beautiful.

I am going to spend time removing the residue from headgasket and intake/exhaust gaskets, but you get the idea.

This head had 180,000+ miles of daily driving. It was formerly in a homemade turbocharged E34... the kid I bought it from said he never head detonation since he was running 7 or 8 psi on a T3, and now I 100% believe him!

Nice project! Most people only ever work on the i6's and that badass little v8 in the 540i's.
Personally, I would polish those combustion chamber's until they're smooth. You can take it to a mirror finish if you want, but whatever.
It keeps hotspots off the chamber, and also keeps the formation of carbon deposites (which also cause hot-spots) to a minimum over time.

Re: Little update on my "Home made turbo" setup
 

I had the machine shot soda blast my block - ------- amazing how it comes out. No marks from beads of any sort, just the raw casting. You can't help any pitting from corrosion, but all the white ---- disappears. Looks like a sick build, maybe too much so for HMT :o

Re: Little update on my "Home made turbo" setup
 

haha yeah this build is technically already done and been running since summer, the motor is just "phase 2"

Here is the setup

I love your car/setup :) Good work ;)

Re: Little update on my "Home made turbo" setup
 

thats cool. i have a 95 m3 that i hope will be boosted if i can ever figure out where to put the turbo. so for now i will just work on the civic

Re: Little update on my "Home made turbo" setup
 

very nice.. i was lookin at bmws again today, test drove a 93 325i manual, it was nice but i found out it was salvage

Re: Little update on my "Home made turbo" setup
 

All E36 guys run them bottom mounted down by the ground. It sucks because of oil drainage and access to the turbo. There are a couple top mount manifolds but they're $$$. Do what I did - make your own ----.

----, if your breakin it down that much you might as well get some beefy rods and pistons
