Anyone heard of this swap or have any links???

If a V6 is used, the weight distribution of the car could be improved over that of a straight 6. OP, I think you're on your own regarding mounts and details, but it's an interesting idea.

[Fidhle007]

You prove it since you are making the claim that you weighed them.
You simply said the M20 and S50, didin't specify just the block, the whole engine, or everything including manifolds and fluids etc. Here it says the s50 (look at m50 since the engine labeled s50 on that site refers to the euro s50) weighs 41 pounds more than the m20... http://www.bimmerforums.com/engine_faq.php
BTW that most likely referring to either the dry weight of only the engine itself or just the bottom end.

Anyway at the very least the statement as a whole was false since you said the m20 makes more power than the s50. Regardless of what you meant, that is what the statement read.:D

Wet weight of the car before swap and after swap: 2800 w/ M20 @2750 w/ S50. At no point did I say the M20 made as much power as the S50 and have gone back and edited my post so even morons like you can understand it.

b230ft swap do it

Even though these "brick" engines (so named because the car is shaped like a brick) are a dime a dozen here, and I have seen a few done up in 240's and even a ridonculous one in a P1800 wagon, I'm still kind of leaning towards the 3.8L GM. The main reason is I can have extremely good power numbers right out of the box with no mods to the engine, and all I need is a bigger fuel pump, the engine, a transmission, a wiring harness, and an ECM, and a welder basically...I know there will be LOTS of other things I need, but that's the meat and potatoes of it... Even doing forced induction on what I already have would cost more and take longer... I think I'm going to start selling some E30 parts I have laying around and start piecing this thing together. I will be posting pics and making a detailed build thread about it as well. Hopefully as I get rolling someone can sticky it so some other people may get interested. A lot of people underestimate these engines, but having owned one and gone 156mph in a front wheel drive V-6 four door grocery getter.... I'm a believer.... Of course the 4T65E-HD trannys they come with lick cow cum off fence posts, but I guess GM can't be as good as the euros on everything.... If anyone knows of this swap being attempted or if you can find a link, let me know. Or if anyone may be looking for certain Cabriolet parts that I won't need, I'll be posting a list of what I have in the classifieds. You can email me too at warmsquash1@yahoo.com if you want to see if I have something. Thanks in advance!!

......so you want to be different........and you want links to other people that have done the swap.




ok?

Yes and yes. I don't need a step by step walkthrough, just mainly if anyone has tackled the wiring. Its my one achilles heel. I can do it if I want, just would rather cheat a little on this one. I can do anything else that's required blindfolded (as time and budget permit). It will be challenging, but not impossible. But since it appears so far that I will be the first or at least ONE of the first people to do this swap, I guess I'm going to have to figure it out on my own and make sure I do a damn good job of taking pictures and posting a write up... :pimp:

So you're saying i'm a moron because you can't express your thoughts in a way that other people can understand them?:roll: You said it, that's why you went back and edited it to not look like a moron.

And how is typing some numbers and pressing submit reply "proof" that the m20 weights more than the s50? I can make up claims and numbers too, that's not proof in any way.

Already posted numbers, kid.

^ Did you even read what you just quoted?:roll:

Already replied to that, kid.


I don't see any of this "proof" you speak of.

[Fidhle007]

There's a difference here, I don't care. I could go take a stock E30 and weigh it and then take one of my swap cars and weigh that too but that takes more effort then it's worth to argue with you. Actually, arguing with you is too much effort in the first place. I build these cars for a living and have actually had them on scales pre and post-swap. If you choose not to believe my "claims" that's your loss. I'm simply offering what I've learned from my experience up to the community but if you would like to make your own discoveries, be my guest.

I honestly don't know which is heavier, i'm not even arguing about that. My point is that I don't think your weights accurately reflect the weight difference of the engine + trans. Sure you may have weighed the car before and after swap, but even if those weights are accurate, it doesn't mean the m20 + getrag is heavier. There are many variables that could have caused that difference in weight, for example, just one gallon of gasoline weighs a little over 6 lbs, so even if at the second weighing there was only a couple gallons of gas more, that could account for the difference alone. Then there's the impact on weight of other things removed. Did you remove AC, power steering, oil cooler, washer fluid reservoir, sound deadening, or cruise control? I highly doubt you kept all of that in when you did the swap.

An accurate comparison would be weighing the engines or transmissions alone, outside of the car, like someone did here with the m10, m20 and m30 and their corresponding transmissions:

[Fidhle007]

I removed nothing except the oil cooler. A/C had been deleted off the M20 previous to the weigh in and my cruise was still fully functional. (Cruise control only weighs a few pounds anyway...) Both weights were with a full tank of gas and roughly the same exhaust but I did lose a few pounds on the headers for the 24v engine. It was 10lbs at most though so hardly significant although could be a contributing factor. My point is less about the S50 being lighter than the M20, because I have no idea how other people would do their swaps, but more to point out that it's most definitely NOT HEAVIER which seems to be the general myth. It's going to be about the same and you can have nearly 100 more HP (or very close to what the OP was looking for with his V6 swap) with almost no custom work required.

I'm sorry if I come off as abrasive, I am. I work on these cars for a living and have developed a set of opinions about what works and what doesn't based on my experience. I'm happy to share my thoughts but I tend to be grouchy when provoked. It's a common theme...

OP: It will be somewhat hard to get the L67 supercharged engine to mate up and work correctly with a (presumably) T5. I seem to recall this being discussed on clubgp or something rather. Your best bet would be to get the complete 3.8 drivetrain from a Camaro or Firebird. Even though it's not supercharged, it's still 200 hp/225 lb ft. unmodified. Pretty stout for an e30!

[DTM190]

Here is wet complete M20B25 vs M52B28 (i dont know enough about the US S50s to know if they are alloy block or not but thought it might help)
