Sweet project. I used to have a '72 '02 in similar condition to your starting point, which is why I sold it- lack of time, money and knowhow.

Looks like you're set now, but
M20= timing belt
M10= timing chain

Should be sweet though. Good luck.

Man, I hope somebody saved it. It doesn't look to far gone!

And yeah I would prefer a timing chain over the timing belt, but as long as I keep it as a regular maintenance item I don't think it will be to bad of a problem.

Given the amount of work you are able to do I dont think its a big deal for you to pull a M20 out of it were to blow and throw another one in. Access to a shop and knowledge of how to use the tools = priceless

it wont blow if you replace the WP/TB/Tensioner every 60K as you are supposed to.

Exactly, that and it's not so much being able to do the work as it would be paying to get new parts and/or an new engine. I'd much rather do the $100 in maint every 3 yrs lol.

for sure.and the first time doing it it can take a bit, but I would bet if I had to do it again I could ahve it done in about 3 hours.

This past weekend consisted of a LOT of running around. Which basically means that I didn't get nearly as much done as I was hoping. However there is still some progress to report.

As I mentioned earlier, last weekend I went and picked up a 'craigslist special' m20b27 'eta' motor for dirt cheap. That catch being that it needed to be rebuilt. Luckily enough for me I was planning on an engine rebuild anyway, so the price was great. For those of you that don't know, the m20 basically came in 3 versions in he e30, the b25 (the 'i' variant), the b27 (the 'e' varient) and finally the Super ETA, which is a combination of the two. The 'i' variant is the one we all know and love with roughly 170 hp and torque. The 'e' varient (eta) was an economy version, producing a whopping 180 torque but only 120 hp. The one thing the eta did have going for it was a larger displacement of 2.7L. The super eta was just the eta block and rods with special pistons and the 'i' head (distinguishable by the casting number 885). It bumped the power output slightly to ~ 127 hp.

Just to use the eta engine by itself in a stock configuration would be silly, since it is only slightly more powerful than the M10 in stock form. So I then began looking for some other options and settled on a stroked 2.7 hybrid. This will involve the eta block (for extra clearance around the rods), the eta rods and the eta crank matted with a set of 'i' pistons and an 'i' head. Now, if it was just assembled like that, the difference in rod length and piston height between the two versions would result in a compression ration of ~8.0 which is less than ideal for a NA build. The solution to this problem is to deck the block 2mm, which will bring the compression ratio back up to where it was with the regular m20b25 while adding .2L displacement.

So now that I had an 'eta' block, rods and crank, I went on the hunt for the 'i' parts I would need. After some wtb threads I was able to find an entire 'i' engine that had bent some valves (Thanks Bill) and another 885 head with a broken rocker (Thanks Ed). I then proceeded to tear into them and see what I had to work with.

Here's one of the 'i' heads, torn apart all except the valves. I still need to pick up a valve spring compressor to get those out of there.



The other 885 head. Both of them had roughly the same camshaft wear, which was slightly more than I was hoping for. I'll have to see what the machine shop says as far as what is acceptable for cam bearing surfaces. So long as the bearing surface on one of the heads is alright I'll be fine since I'm picking up either the 284/272 or the 288/288 schrick later this month.



Then it was on to taking apart the 'i' block to get to the pistons. Wear on the block was actually better than I'd hoped for, which is ironic because I'm not planning on using anything but the pistons. At least I have a back up plan in case the eta block doesn't check up.

Pistons, Rods and Main Caps:




2.5L crank in engine block:



At that point I ran out of time and had to head back to campus. Next on the agenda is to tear apart the eta engine and inspect the crank and block for wear. Assuming those check out alright I'll then take the pistons, crank, block and head of choice to the machine shop to have then re-inspected, cleaned and machined as needed.

Also, saturday morning I went over and picked up an e30 rear subframe (thanks again Bill). Included was the 3.73 lsd diff and rear disc brake setup. This mounts in the same basic way that the 2002 rear subframe mounts, except that I'm pretty certain the track width is wider. This means that I will most likely end up modifying the the 2002 and e30 subframes to make 1 hybrid, using the e30 diff and trailing arms/brakes with the 2002 mounting points.



Can't wait to feel that LSD put down all 200 horses


Oh, and there should be a small tidal wave of parts flowing in this week so stay tuned.

as far as the spring compressor for the valve springs be wary. you can look in my build thred for the details, but basically I got a generic overhead one from amazon for about 25 bucks, and then proceeded to have to shave it down and make it more narrow to fit the BMW head. all the details are in the build thread but just a heads up it is still a pain unless you spend big money and get a bmw specific one.

I did some reading on the different types of valve spring compressors specifically with use on the m20 heads and nobody had anything nice to say about the kind you got lol. I ended up going with a craftsman c-type clamp that a couple of guys on e30 tech have used with good results.



http://www.sears.com/shc/s/p_10153_1...&blockType=G24

Once that comes in I can finish disassembling the 885 heads along with the eta block. Assuming I can't find any damage or issues the parts will then get sent to the machine shop for a more thorough inspection/cleaning. If they pass that test then the head will get resurfaced, the block will get decked and re-assembly can get started!!

good luck with that tool let me know how well it works. I have an extra cam if you plan on doing a custom regrind.

Thanks, I'll keep that in mind. Right now I'm leaning towards a schrick 288, but it depends on how much the machining will run me.

So Thursday night I needed to finish tearing apart the engines to see what condition the insides in. First thing was to finish stripping the 'i' block and get the crank shaft out.

The empty block ready to go to the machine shop:




The 2.5L crank:




The 'i' pistons, rods and main bearing caps all together so I don't loose em.




All the pieces parts taken off the block. Mounts, oil filter housing, pulleys etc:



---------- Post added at 12:54 PM ---------- Previous post was at 12:38 PM ----------

Next on the chopping block is the 'eta' engine. It has no idea what's coming:







Popped the head off. Here you can see what the eta pistons look like. They would be perfect for boost (giving a CR of ~8.0 with the 'i' head), so I'll hold on to them for now in case I decide to go down that route in a year or two.




The eta pistons and rods. These rods are 130mm where the 'i' rods are 135mm. This will help to compensate for the longer stroke of the crank.




The eta crank. Looks a lot like the 'i' crank lol.



Over all the eta crank was in great condtion. The only bad spots were two places I could catch my fingernail on the bearing surfaces. Hopefully it can be polished out and reused.

The last thing to do before heading to the machine shop was to get the valve springs out of the head.

My purdy new valve spring compressor. Worked flawlessly and got it for under $20 from sears:



Also picked up a real set of feeler gauges. Wasn't expecting it to come in a nice roll-up pouch but no complaints here:



With the valves out I could do a preliminary check of flatness on the head. Looks like it's right around 0.0025" max, so it should be easy to get it smoothed out again.






All the parts wrapped up and ready to go to the machine shop. Who says the e46 can't haul parts.

looking good. If I end up tearing my head apart for boost again I am definitly buy that thing.

Look like I'm gonna have to get my flair on. Just picked these up from Oregon. Originally used as centerlocks back in the day, they're original BBS 3-piece E63 wheels (no relation to the bmw chassis code system, just a coincidence). 11" magnesium center with 13x6" front lips and 13x8" rear lips. Rears come in at 9.1 lbs a piece, how's that for low unsprung weight and rotating mass lol. The original equipment '02 wheels were 13x5 or 5.5, so these should give me lots more grippy stuff where it counts. I may end up getting new lips for the front from bbs to get the offset where I want and possibly even bump it up to a square set up for handling, but I'll cross that bridge once I get the flares figured out.

One pic for now, more when they get here.
