Have had a busy wknd! Have now fitted the 2.1, its in and running! i'm knackered! have to stop the radiator deciding to drop coolant all over the place for no particulat reason (the rad and all hoses are fine), then its on with the running-in! i had a good mate of mine helping and it still took most of fri, sat and today to get it all sorted, although i did repaint the engine bay + loads of parts, properly bench build and test the new engine etc. which took a long time. The old engine was unsurprisingly in very good condition indeed. Anyway now have the 2.1 in with all new gaskets, timing chain, single mass flywheel etc, and the engine bay is looking very clean. I'm pretty chuffed.
Here's some pics:

VERY NICE!!! Can't wait to see dyno and seat-of-the-pants results!!:D

Okay, granted, I really want to know more about your 2.1L stroker, but can you tell me what process you used to paint your engine bay? I got all my rust issues sorted and primered those areas with a POR-15 over-rust primer. I have everything taped off and am about to hit it with some generic grey sandable primer and then some of this Dupli-Color "Arctic White" I found at the local parts store in spray cans. Then probably a quick shot of clear enamel to lock it in.
If there's a better paint or method than my white trash one, than I'd love to hear about it. Your engine bay is definately the cleanest I've ever seen!
I love your valve cover and intake manifold too.
Also want to hear about your experiences with the single mass flywheel once you've had some time with it. Did you go with the M20 setup?
-
Looking really good!
Few questions:
-- What's that cylindrical thing @ 3 o'clock in the the 1st pic? Some sort of catch can? I thought you guys didn't get the charcoal canister?
-- What's with your exhuast header looking different (or are my eyes deceiving me) ?
-- Do you guys ever relocate your batteries to the rear?

I thought only verts had it up front.

Thanks guys!
Answers to questions:
-The engine bay was not done as well as I would have liked - but I'm a perfectionist. Main reason being that the whole engine transplant was done in a weekend - the top pictures are from friday, the last picture sunday. The process was nothing unusual. I used gunk and washing up liquid and household detergent etc to get the engine bay spanking clean, then wire brushed and sanded all the rusty btis and bits with yellowed lacquer off. I put down a few coats of white primer, then a few of the correct alpine white II paint using rattle cans. I haven't used any lacquer as the rattle can only suggests to use lacquer with metallics etc. although in hindsight I'm not sure whether this was the best move and I'm considering giving it a light dusting where i can just to seal it.
-The single mass flywheel is an M40 effort, sadly not lightened any more than standard, but I haven't devoted too much attention to this as I was more concerned with getting the engine spot on, and I potentially intend to have the engine out again after 10k or so to check everything and can revisit this then. If not, I'll have the box off at some point. The flywheel is still 9kgs, so not much lighter than a dual mass.
-The cylindrical thing is the P/S pump
-The exhaust header is different, eagle eyes there! Sadly in the UK we have the manifold shown which is not quite as nice as the LHD ones. The reason is to give clearance for the steering rack U/J. It's not a bad design, but the pipes are unequal length. there are some aftermarket items, and later I may collect some e36 m42/4 manifolds to see whether I can make something fit.
-(Battery is in the front on UK cars sheepdog) Some guys relocate the battery to the rear, I have just under 20kgs of stereo at the front of my boot (I run a spacesaver spare wheel to free 10kgs from further back in the boot), I don't really want to shift any more weight to the rear at the moment, I quite like the cubby hole too!
I can't wait to have her run in. My brother does some serious mileage and is insured on my car so I will get him to help run it in, it will suit him and me as i won't have to spend on petrol and waste time pottering around for no reason and he'll enjoy the car no doubt.
-
CONGRATS man... !!!!
edit: hmmm.... those pistons look suspiciously large!
-
Looks good and congrats but, what happened to the ITB's?
-
febi, oh yes, very large indeed. not as big as you're intending though iirc! The 2.1 runs ok-ish on the motronic btw, will obviously be mapped on megasquirt soon though.
the ITBs will be on a bit later, need to get the engine run in, mapped etc and to be on top of the MS stuff before then. Need some cams too. Can't wait for the TBs, will be a while though as the plenum's still at the bodyshop

-The cylindrical thing is the P/S pump
The aluminum thing beneath the PS reservoir is the P/S pump? Maybe you misunderstood my question? I don't recollect seeing that on any of our US spec e30s...anyone with me on this or am I missing something here?
-

I see it too. Definately not the PS pump. It's right beneath the PS Reservoir. That's exactly the same location as the charcoal canister on our US cars, but this looks different. Hmmm...
Hey Airik... If I remember correctly from some of the schematics I looked at, the UK cars have the fuel filter in the engine bay. That's probably what that is. :cool:
Tim, we have a charcoal canister in that location and our fuel filter is under the car on the driver's side along side the fuel tank. I presume that yours is in the engine bay, and that's what we're looking at.
-
Paint job looks pretty good from here Tim. Did you put a clear over it, or did your Alpenweiss II spray paint have a built-in clear? I heard you can't do that with the enamel unless you mix it right there and add a hardener, but I know JACK SQUAT about body and paint work.
I painted my intake and valve covers with Rust-O-lium silver... I really don't like it, but better than it was. I guess when I have some more time I'll try to recreate the black "winkle coat" finnish on the early M cars. I just don't have time to do all that right now.
-
oops, yeah its the fuel filter. apologies, didn't mean to insult your intelligence guys!

is their any advantage to this? i find it strange that they relocated it all the way to engine bay..
-
Hah, no worries Tim S. As much as we like to say our cars are the same little difference like this spark my interest a lot of times. What do you guys have in place of the rear fuel filter on the d.side infront of the rear subframe?
IIRC the charcoal canister thing is just for emissions over here. I am not 100% though.
Dan - just the car driving already, rustoleum or no rustoleum. You missd the CCA auto-x again this past Sunday :mad:
-
i would get the engine mapped with the TB's

I know, I know... But, I hate the thought of not taking care of this stuff while everythings out of the way. It's been a slow process as I'm essentially working 2 full time jobs now. 1 is my real job, the 2nd is getting this car pieced back together.
Car will be all back in one piece next week as I'm driving down for the event at Barber.
I'm doing the Audi Driving School at Road Atlanta this weekend. Fortunately, we're using thier cars! :D
I'm going to Robeling Road in June, and I probably need to sign up for the Peachstate BMWCCA school at Road A for June, if it isn't full already. Are you going?
-
I'll be @ the Road ATL mini track session on 6/4 and for the BMWCCA HPDE 7/8 & 7/9. Roebling is a bit far for me as I don't have a trailer assuming something happens :eek:

I'm not sure you know. Only the petrol tank sits in front of the rear subframe on the driver's side - when I have some more time I'll try to see exactly what you mean.
Got 200 miles on the engine so far, went for a long drive to devon yesterday, everything is going pretty well. She ran a little hot for the first half hour or so, I think there was greater friction as everything bedded in, but since then everything has been great. the fuelling doesn't seem perfect, but is plenty good enough to run with. Cranking is a little difficult, but when I go to MS I can just increase the pulsewidths on cranking a little. I've changed the oil once after 1/2 hr running, and the oil seemed fine, nothing untoward going on. I'm not sure about the performance as I've only used light throttle and low revs as i run her in, a friend wants me to get the car on the rollers on the 23rd, I'm not sure if I'll have enough miles in by then. I don't think I'll be on MS then either. we'll see.
-
it's all too much tim! good shit.
-
what compression ratio is in your engine tim?
-
i would get the engine mapped with the TB's
why's that? I'm running SD at the moment, and so I want to get a strong map before putting the throttles on, at which point I may go blended alpha-n/SD or hybrid alpha-n. but then I'll have cams on too. i need to run the engine in gently, putting the tbs on now would not be wise.
The CR is a bit under 11:1 for the moment, when I work over the head I will get it skimmed to bring it to 11:1.
Thanks for all the kind comments guys!
-
how far will you be able to rev it?
-
the bottom end will be strong to significantly over 7k rpm, but the rest of the engine won't be up to much more than 7k rpm. after i've ran her in and finished mapping, until the head work/cams/itbs, i will be revving to 7k, after that maybe a little higher.
-
What if you put more aggresive Cams and valve springs? A high revving 2.1L would be awesome
-

yeah when i get around to doing the cams, big valve head and putting the ITBs on I will rev it further, but only once the engine has settled right in and done a good few thousand miles - i plan a partial rebuild at some point to check everything over and do the top end of the engine. i like to take my time and do everything properly, and this new engine is still running in, so revving high isn't high on my priorities at the moment, but i've built it with components that are capable of revving highly.
-
Been playing with my intake today, I got it back off the bodyshop as the guy's busy and hasn't got around to trying to fix the bubbling problem and spray it again. so i told him i'd have a crack at sorting the bubbling out etc, then he can spray it for me. i think i'm getting there now, p40'd heavily over the fibreglass after digging out all the bits that had bubbled, have had it in front of my fire for ages after this paintjob and seems ok at the mo, we'll see. if it doesn't bubble i'll get it sprayed properly again. Got some 23.8lb injectors to go on too, its all slowly coming together. the engine's running in nicely, feels a bit lean on the motronic, but a friend is trying to borrow a lambda meter thing so we can have a tinker with the MS mapping.

im at a loss of words...
all i can say is keep us updated!
-
Can we get some audio of the ITBs with the plenum? :D
-
which s50 are those off of? probably are the same on both?
-
more details on the 4 throttle bodies please! That engine just keeps getting better.
-
the s50b30 and b32 throttle bodies are different, and both obviously need a lot of work to fit an m42. i think in my members bit there's some stuff on my itbs. the vacuum rail, fuel rail etc needed modding, throttle linkage chopping, flatting and re-tapping, the bodies themselves needed machining to mate up to our head and a few other smaller odds and sods
I'll dig out some pics of the bodies without the plenum on later.
the good news is there's no bubbling on the plenum after spending the night at high temps. need to tidy up some parts of it and properly prep it for painting. im thinking of having it gloss black again, not sure if i want any transfers on top, mb a silver 'BMW M Power' logo, although i'm not sure. any suggestions appreciated!
i'll work on getting some audio once everything's sorted properly!
