So many similarities to my M20 swap: mounted the coil the same, + terminal junction box, C101 plug mounted in the same spot, even the same bends in the engine hoist hook. Makes me feel good about how I laid mine out.

Is the hook too tall to clear the hood or something? I have the shorter '85 m20b23 hook in my car.

Mine was bent from lifting the engine and trans together with the engine hoist. I should have used a load leveler.

The only engine/trans i've put into a car so far had been an m30+5spd out of an e32 (1 of 200 5spd US '88 735i's!) into an e30.... the adjustment on the load leveler wasn't even enough to clear the rad support. can't imagine what I would have done without the leveler

[bassboy3313]

Looks real good! Congrats! Feels good to have a short To Do list doesn't it?

Are you running the tach signal from the fuse box plug?

Thanks man! It does feel good. As for twch, I am using a windows tablet running tunerstudio for my gauges.

Mine bent from doing the same thing. I even used a load leveler too. It has been lifted with hoist many times, so I imagine it is getting pretty worn from bending so many times. Will definitely get replaced if it ever needs to be lifted again.

Great work! Are you running the registered version of tunerstudio? I've been contemplating paying for the extras that come with the paid registration, but I'd like to see someone else do it first and let me know it is worthwhile.

[bassboy3313]

Yes I am and it's definitely worth while.

I did not see a coolant over flow tank ?

M42 radiator has it built into it. Attached to drivers side of radiator.

Good progress this weekend. Got the seat belts bolted down, rear strut brace/battery tray welded in, new battery strapped down & electrical taped/wire loomed all the exposed wires in engine bay. Also got the front end back together with signals and HIDs working as they should.

E30 projectors and housings?

I think it's weird that a lot of e21 people swap in the m42 rad to clean up the bay because of this, while people swap the e30 expansion tank into e36's because it's the 'euro' setup.

[bassboy3313]

Yup you got it. And that is pretty interesting about overflow tank setups. Didn't know that about e36s.

The e30 style is self bleeding, while the US e36 tank has the manual bleeder screw. US cars have a jump post and sometimes emissions stuff in that location

Hey bassboy... Random question. Where'd did you get your profile photo? I'd love to see more (high res) pictures of that car.

I got it from google images actually.

Do you have a higher resolution copy you could post?

Took her to the local bmw picnic we have every year and not one hickup. Felt so nice to drive! Definitely gets up and goes and is totally controllable through the slidy corners too. What a blast!!

[bassboy3313]

Lower hose clamp was loose, so tightening that hopefully has fixed the leak. I also took the turbo off to try and fix an exhaust leak. Using ultra copper gasket sealant as amother layer of sealing hopefully fixed that as well. Waiting till tomorrow to fire it up so the sealant has full time to cure. Put turbo blanket on as well.



Got some more goodies in the mail too.

UUC EVO3 shifter. After feeling this shifter in a friends car I had to have one. Got a hell of a deal on it off ebay too.

Electronic boost controller and db15 harness to control boost through megasquirt.

i put one of those shifters in my M3, very nice. too bad i can't enjoy it anymore.

[bassboy3313]

Shifter feels amazing now! So much crisper and tight. Definitely worth it.

Did some surgery to my megasquirt ecu today. Been wanting to have megasquirt control the cooling fan, but never knew how to get it working. After talking with Keith, the guy who made the unit, turned out to be easier than I thought.



Had to solder in 2 wires in order to have relay control from a spare pin on the db15. After doing that and buttoning the ecu back up, just had to run the ground wire from a 40A relay to the correct pin on db15 connector and tweak the settings in tunerstudio.

I am having one issue tho which I believe I found the culprit. With ignition off, the radiator fan will run constantly. With ignition on, it turns off unless engine temp is higher than allowed through MS. I then realized that I wired the relay to be constant power for both +12v pins. Which makes sense why the fan is running constantly when ignition is off. I'll have to run another switched source wire to the relay tomorrow morning to see if that solves it.

I also need to figure out the boost control settings since I got an error in tunerstudio when I turned it on with default settings.

First time seeing this build! Wow, that went nicely. How did the soundproofing work for you and what variety did you use? Not fond of the old insulation myself. And do you have any other pictures of the m42 radiator install? I picked one up to put it in my car

[bassboy3313]

Thanks! Not so much soundproofing as it was heat blocking. I just laid down some aluminum backing tar paper in key heat areas. Does great so far and not as noisy as I figured, so worked both ways I guess. I don't really have any other pics of radiator. Used 2 of the small e30 rad mounts, cut slots in frame rail for them to mount and had to get creative with hoses. Nothing too bad.
