E30 M52
-
2 setbacks early in the game:
-front lifting point/corner of the head is cracked (engine didnt come with a lifting hook, just a lifting strap wrapped around it)
Not a critical mission failure, just an annoyance from a previous mechanic doing something wrong while lifting the engine
I drilled out the ends of the crack, called a mobile welder, they wouldn't do it because its cast alum. (Nonsense, ive had a head and trans case welded before) so I put some JB Weld into the crack and wiped it clean in addition to the drilled holes to keep
It from expanding. I will need to come up with another front lifting point that will work with a load leveler.
-After sending back the basic S52 tune, I received the M52 tune but it is for 91 octane and um... an M52B25, instead of a B28. Rev limit according to the website on that one is "7400+" so needless to say I am awaiting a response from my email to Sssquid tuning.
Not mad at them or anything, they have been awesome, I just need the tune to be right though.
I think 7k is dinan stuff

Sssquid Tuning responded today, checked their records and I do in fact have the M52B28 tune as desired, the B25 was a typo, however, the 7400rpm limiter isn't sitting well with me because I know how these 24v engines get a bit crabby about harmonics after the big hand hits the 7 and the tune was for 91 octane anyways so I am having a new tune sent for 93 octane with a 7100 soft limit and a 7250 hard limit. At some point when its in the car I will put it on a dyno and see how its doing and probably get another tune revision.
I have considered making my core support removable for a while now but I think I need to make it happen for this install. I just don't think the 24V was meant to be lifted at the extreme angles required to fit into an E30. I will be looking into removable core support gameplans and alternate front engine lifting points tonight.

let all the air out of your front tires and jack the rear of the car way up in the air.
insertion angle is all about positioning. car-ma sutra, or something.

Really not needed. I've pulled / installed m5x/s5x motors in e30's 10 to 15 times and only 3 or 4 have been with removable core supports. It's not a terrible fit.

Continuing on with my MO of spending just a few minutes a day on the project, I finally got the intake manifold off.
It isnt called a "mess under the intake" for no reason!
OBD1 will only slightly help with that.
For those that arent aware of the difference between an M50 manifold (thick and healthy) and an M52 manifold (frail and anemic), here it is
After I remove the E39 harness, brackets, and accessories I will be plenty busy cleaning the block.
RealOEM will become invaluable as I make a list of other clips/brackets/hoses that I didnt buy yet to mount the OBD1 harness and accessories.

The race is on!

Try oven cleaner if you haven't already!

All you have to do is bolt a supercharger on to win the race (this comment works two ways)
I would be very interested to see how this M52 would do against an S50 though
