E30 S52 Build + Turbo Install

[Sh3rpak!ng]

A friend of mine here in LA is from Milwaukee and was visiting his family a few weeks ago and randomly saw your car in a parking lot. He snapped some pictures and sent them to me. I only saw the rear photo at first and immediately guessed s52 turbo - and I was right! Then I wondered if you were on the forums, and lo and behold, a month later I randomly stumble upon it!!

Sick build, very impressive and quality work. Subbed for more progress and a retune when you get the headgasket sorted!

I'll keep an eye on this as inspiration for my own!!

What turbo manifold is that?

Good & Tight.

I will get it checked to see if it is flat.

I know there are some companies making turbo and manifold gaskets from inconel, turbo gaskets being more common, I haven't seen any for bmw manifolds though. Be you're best bet, but get ready to shell out for the most expensive gasket you've ever bought.

Pics of the carnage.


-There is some detonation.
-Cyl #1 had a leaky injector for awhile.
-The tune has been super rich.
-I have some port matching todo.







Zipties for the documentation
























I will be ordering a cut ring gasket, new arp head studs, exhaust nuts and researching the best exhaust manifold gasket today. Also, I will take the head into the shop to have it inspected then after it checks out I'll get it back to port match everything then send it back to get cleaned up.

Every tracked s52 I've seen has scored cam bearing caps. Yours aren't too bad, just make sure you match them back up to the right journal and bobs your uncle

I have the rally road oil cooler cap, IE is the same thing slightly different design. It's much cheaper, I believe I bought the rally road cap after my brother bought the IE cap and I saw that the two ports mix and are not completely independent, I remember thinking that you might lose significant oil pressure if you ran a feed off the oil cooler line, but I may be wrong. I just got the rally road cap to be safe.

I got a junkyard oil thermostat and it works excellent lol. S54 thermostat housing would probably be the cleanest and best way to do it but I couldn't see myself forking over $400 for a thermostat housing.

I talked to John and ECS and he said he has sold hundreds of these head gaskets and hasn't had one customer come back with a complaint.

Oil cooler ideas w/ links.

Cooler(s): https://www.cantonracingproducts.com...&category=2350

- Not sure of what to do with the cooler size. I haven't measured anything yet but thinking I could run two of the smaller Canton coolers in tandem behind and to the left and right of the kidney.

Or do I just go S54 oil cooler and call it a day?

The head gasket replacement journey.























Keeping organized.


Too much wear?


I can feel this one with my fingernail.


Now I just need to disconnect my downpipe and remove the ARP head bolts and see the carnage.

New setup. Running 245s in the front and 255s in rear, 90mm studs.

[DrLeadFoot]

A lot happening! Congrat!

Thanks!! Can't wait for things to calm down.

I also got married!

Ordered new rear wheel bearings, the allen bolts that attaches the axels to the diff. Gotta get that new diff installed!

Going to have the talented Snap powder coat the M-Coupe cover and some other parts.

Side note, these tires are awesome! Slowly pushing the limits while being scared of curbs and cement walls but it's on rails! I still need to address some rubbing issues. Thinking I'll totally cut out the inner fender a quarter of the way from the outside of the car and fiberglass it back shut and/or purchase some adjustable rear coils with some stiffer springs.

Test fitted the wheels with out the tires. The fronts look good. 17x9 et25 with a 15mm spacer making them et10. 245/40s should be okay.

The rears are so tight but don't touch. 1mm of clearance from the trailing arm and spring perch. 17x10 et20. I hope the 255/40s stretch a bit on the 10in wheel.

Urban Motorworx is mounting them and should be ready for pick up tomorrow morning.

Hopefully concours can squeeze me in for an alignment tomorrow if all goes well with the fitment.

The parts are slowing coming in!
