As most know I have an unhealthy obsession with the BMW E30 chassis cars, it runs in the family. Dad and I started looking for a turn key E30 M3 race car last fall to replace out haggard Chump/WRL E30 that we will be retiring and selling this winter. We're taking a break from racing but still wanted to do some track days, instructing and other poo poo. After not finding anything turn key that we liked I decided to pick up a project because I'm an idiot. So I bought a race car rolling chassis and an engine. They aren't supposed to work together at all. This is my first engine swap and likely way more of a project than I am anticipating. Either way it'll be fun and I'll need all the help I can get. I'll probably also have general car and garage stuff going on that will end up in this thread. Garage needs a clean and reorganize, truck needs to be lowered, VW needs a suspension refresh, 320i needs Megasquirt, etc. The Car Car is a 1988 E30 M3 that was gutted and started being turned into a track car 10+ years ago. Guy that started the work ran into some financial trouble and had to sell the car quick. It was sold and sat at one of the top US E30 M3 shops for the past 10 years largely untouched. Owner of the shop pulled the S52 that was in it planning to put in a S54 but never got around to it. He sent out an email this spring selling it and I picked it up a couple months ago then promptly didn't do poo poo with it. List of goodies from his listing: code:
The Engine So I'd love to throw in a proper s14 but in an attempt to be at least a little financially responsible that is not going to happen. I looked at a lot of options and ended up deciding on the F20C out of a Honda S2000. Engine is from a 2002 AP1 with 31k miles. I have engine, transmission, ecu, fuse box, engine and bay wiring harness, radiator, stock intake and some miscellaneous hardware. I will need to do the AP2 retainers and oil squirters so I don't blow the thing up too quickly. F20 was picked because it makes good power (240hp), is light (426lb with trans), has a nice high rev limit and wasn't too expensive. E30's handle best with a light engine in front, I've driven everything from M10 to S54 to M60 powered cars and the lighter the engine the better. I also looked at building a M42 stroker, rotary, newer I4 BMW engines and several other options. Stuff So now the fun stuff...this engine will not fit without modifying things. The steering rack in the s2k sits in front of the engine, in an e30 chassis the oil pan interferes with the subframe and steering rack. In order to place the engine as low and as far back as possible you need to modify the oil pan or subframe, if not the hood will not close. I plan to modify the subframe and move the steering rack (as little as possible) to place the engine as low and far back as I can get it. In addition to this I'll be attempting to line up the shifter turret with the stock cutout in the e30 body. Plan is initial test fit with and without the oil pan installed. I will be taking a ton of measurements and pictures of this for later reference. Once I determine where the engine will like up with the subframe I will make temporary mounts. I'll make a simple jig to locate the mounting points for the subframe to body and chop out the center section that interferes with the oil pan. Then stick engine on a stand upside-down, mount what's left of the subframe and start piecing things together. Sounds simple right???

So the kind of good news is this has been done before and I've talked to the person that did it. He has over 40k on this swap and it's his daily driver. He modified the oil pan for more clearance then pushed the steering rack into the subframe a bit. This is an option I'm looking at but I'd rather not modify the oil pan this way since it reduces volume and makes adding a pan baffle a little more difficult. Some helpful things he told me. He fought with the factory wiring and stuff for a long time, hes in CA and needed to pass inspection which I won't. He used the stock S2000 radiator, I got one with my swap and may use it. He fought with a two piece driveshaft for a while before getting a custom one made. Stock S2000 engine mount arms with OEM E30 engine mounts, I will probably go this route but use poly engine mounts. Might also look at making custom mount arms to get the engine lower and exactly where I want it. NitroSpazzz fucked around with this message at 14:49 on Sep 13, 2016 |

Like I said on FB, you need a custom plate for that. Something like L8R H8R. I can't wait to hear it.

have you looked into getting a custom built tubular subframe by the arc asylum dude? That looks like its the way to go

BraveUlysses posted:have you looked into getting a custom built tubular subframe by the arc asylum dude? That looks like its the way to go For reference here's his for S54 swap: That picture brings up one thing I need to figure out, the steering rack. Stock the E30 rack sits rearward of tie rod connection point (I need to measure how far), it is VERY likely I'm going to have to move the steering rack to make this fit. Say the stock rack center line is 1.5 inches behind the tie rod points, if I move it to 1.5 inches ahead how much would I gently caress my steering/suspension geometry?

Ok, this is cool, but as with any other heavily-modded E30 M3, I have to ask; wouldn't it be cheaper to sell the M3 shell and start with a cooking model E30? There is a serious price discrepancy.

Jesus poo poo, TT44s in the rear? Proper bits. You know they have TTX front strut setups too right? Just a bit of fab... (and probably doubling the cost of the shell) Nice basis and cool idea. Quick thing on the todo though - you don't need a bias valve with a pedal box that has a movable pivot. Because, you know, I'm sure that will make or break the bank.
