Finally tearing into the engine pulled from a non-running '94 940T so I can plop it into my '91 740T. I have pretty much zero prior experience with engine building, but gotta start somewhere. Not seeking to break any records, but would like to have a bit more pep than stock without sacrificing daily drivability

Brief history of the engine from what I was told: it overheated after the last guy blew a hole in the radiator reservoir, and he tried to rebuild it without replacing the head gasket. Didn't hold compression afterwards, he got frustrated, and sold it to me

I'm pretty certain the block is going to need some love at a machine shop, especially given the notable rust in cylinder 2. Probably worth noting I had to douse the internals through the spark plug and intake manifold holes with PB Blaster to get the engine to move enough to access the bolts holding the torque converter. Is there anything that jumps out in particular I should be wary of at this stage, or should I just finish stripping the block and send it to the professionals? Is the scoring deep enough to be of concern?

I have a couple heads to choose from, one attached to a running '90 NA 740 parts car and the other to the '91T. I'm guessing the heads are all 530s and interchangeable, the one pictured from the '94 940T is a goner I'm guessing, based on the hole where the front of the camshaft sits. Would it be worthwhile to have the head ported, and/or grab an IPD Turbo cam while I'm at it? I'm in California and subject to smog testing unfortunately, so I would need to be mindful of visible upgrades that aren't easily reversible, but I don't imagine pulling the valve cover is part of the standard testing procedure

Either way, open to options and appreciate any constructive community input and advice!

Also if anyone is interested, the '94 940T shell is a rolling slicktop wagon with a clean title, would make for a good base for a drift build, feel free to hit me up if somewhat local to San Diego, I need to get rid of it sooner than later lol

First driver was likely staring at her phone and saw a green light from her peripheral and went for it. Second is basically standard bike behavior downtown, but hey at least he waved

Anyone know what these are, besides a wheel balancer's worst nightmare? This is the only picture unfortunately

What's the purpose of this clip? Seen it on every 7/9 series I've had so far, is it to hold a paper map or something?

First time pulling an engine to rebuild, any advice or insight is welcome! Planning to fully tear it down, if there's anything in particular I should be looking for during the process, that would be great to know. Printed numbers on the side are B230FT 6821105 05121

This came out of a '94 940T, the previous owner ran it after blowing a hole in the radiator while showing off for a girl or something and overheated it. Hoping that the block is still good, if the head is warped, I have a couple more I can replace it with.

The plan is to drop the whole drive train into my '91 740T (pictured). The turbo is still pretty strong on it, but would there be an advantage to using the one from the 940 instead? May look into doing some upgrades as well to produce a bit more power, but nothing super crazy, I am in California so I would still like to be able to pass smog. Also currently undecided on whether to use the crank fan from the 740 or convert to the electric one from the 940, if there's a significant advantage to either, feel free to chime in

I'll probably separate the transmission and get the engine on a stand after the weekend, I'll try to keep you guys updated if interested!
