“That’s the 2.5L DOHC 4 valve per cylinder Non vanos 325i engine from '92.” Thanks for explaining that, I get frustrated reading threads that just give a bunch of code numbers that I don’t know.:biglaugh:(seriously) Good luck.:tup: ---

> [@MPD47](#): > > Would you like it for stupid cheap with trans?? It had mint compression across the board all within 8psi of each other IIRC right around 165~ Maybe, how stupid are we talking? The wife is starting to bitch about my spare parts supply. But an engine and tranny are always worth keeping around for a track car. Which Glen events are you doing? I have to schedule a few more after the cage goes in. Should be a fun car after the swap, it’s not too bad before with a little suspension work. ---

Front 53.6% Rear 46.3% Total weight (3/4 tank of fuel): 2741 Tearing into the e30 as we speak, had to turn the pcar sideways in the barn to get the front of the e30 in due to the amount of boxes of shit I have sitting around right now, but atleast it got me out of the rain. Hopefully should have the e30 prepped, the wiring done, and the m50 prepped for tomorrow. 🙂 More pics soon! ---

Ok, so I lied, it’s going to be a 4 day swap. Got a ton done today, but I dont feel comfortable with how close the fan is to the radiator (when installed which it’s not in these photos) so I refuse to run it like that. Gonna grab a thin electric tomorrow and toss that in place instead. Also going to wire up the connectors (see below) during lunch to make it a plug and play swap. Everything else is pretty much buttoned up other than an exhaust… so I’m going to be driving it straight piped into Buffalo on Thursday to get it tightened up at Mufflerman. Should be entertaining :lol: ![http://www.mturck.com/e30/DSCF3950.jpg](http://www.mturck.com/e30/DSCF3950.jpg) ![http://www.mturck.com/e30/DSCF3955.jpg](http://www.mturck.com/e30/DSCF3955.jpg) ![http://www.mturck.com/e30/DSCF3956.jpg](http://www.mturck.com/e30/DSCF3956.jpg) ![http://www.mturck.com/e30/DSCF3960.jpg](http://www.mturck.com/e30/DSCF3960.jpg) M20, good riddance. ![http://www.mturck.com/e30/DSCF3952.jpg](http://www.mturck.com/e30/DSCF3952.jpg) Ireland Engineering springs 🙂 ![http://www.mturck.com/e30/DSCF3953.jpg](http://www.mturck.com/e30/DSCF3953.jpg) No, there were not any leaks or anything… ![http://www.mturck.com/e30/DSCF3964.jpg](http://www.mturck.com/e30/DSCF3964.jpg) Need to finish wiring up the connectors tomorrow. That’s the e30 engine harness connector (left), and the e36 body harness connector (right) which I need to put together so I can interface the e30 body harness with the e36 engine harness. ![http://www.mturck.com/e30/DSCF3965.jpg](http://www.mturck.com/e30/DSCF3965.jpg) ![http://www.mturck.com/e30/DSCF3966.jpg](http://www.mturck.com/e30/DSCF3966.jpg) e36 pan (top) vs the e34 pan (bottom).

Yeah, I hope to fire it up tomorrow, hopefully there are no issues and I can be doing siqqq burnouts. Gotta pick up my m5 master cylinder from Napa tomorrow (or maybe Skrapper got it for me? Not sure…). Put that on, put the fuel lines on, put the new bolts in the new flex on the driveshaft, drill one hole for the center bearing, put the radiator in, put the electrical plug and play connector in, then it’s ready to go. Still a decent bit, but mostly little stuff. Of course then I have other stuff like the springs and what not that **I** want done for Saturday. ---

The e36 one is significantly wider, it still fits, but the bottom flanged part doesnt line up quite right. I need to cut approx a 1/4" off it and drill a new hole. Will not affect function at all. I’ll take pics to better explain. ---
